FOR AN 8 -BAY T -HANGAR CONSTRUCTION Airport staff requests approval of the contract for the construction of an Eight -Bay T -Hangar with Gray Construction, Inc. for a bid amount of $264,365.00.

A Budget Adjustment is requested to cover the project contingency and the increased cost over the original project estimate. This project will be funded with Airport funds but will generate revenue for the airport. The demand from general aviation for this project is apparent by the waiting list for hangar space kept by Airport Administration. Garver Engineers, the engineers for this project, have recommended the award of this project to Gray Construction, Inc. who was the second lowest bidder The lowest bidder, Phase I Turnkey, Inc., did not sign or complete their proposal and was not recommended by the engineers. The Airport Board at their July 1, 1999, meeting did recommend that the award go to the second lowest bidder, if the lowest bidder did not qualify.

However, Phase 1 Turnkey. Inc. did not sign the Proposal or complete the Proposal -farms." I'hey also did not complete the "Statement of Bidder's Qualifications" section. For these reasons, according to Peggy Vice, Phase 1 Turnkey's bid is disqualified. The second lowest bid was from Gray Construction, Inc. in the amount of $264,364.50. This amount is less than the City's Certified Funding Amount and the Engineer's Estimate. We believe the amount bid by Grey Construction represents a good value to the airport and recommend that the City award the contract to Gray Construction, Inc.

FAYETTEVI LLE THE CITY OF FAYETTEVILLE, ARKANSAS DEPARTMENTAL CORRESPONDENCE TO: FRED HANNA, MAYOR FROM: DALE FREDERICK, AIRPORT MANAGE1 DATE: JANUARY 10, 2000 SUBJECT: CHANGE ORDER #1 TO GRAY CONSTRUCTION The Airport staff requests approval and Mayor's signature for Change Order #1 to Contract #733 with Gray Construction Company. This change order includes three different items which will result in a net increase of $1,253.00 in the price of the construction of an 8 -bay T -Hangar. Item A is needed to remove an installed support beam and replace the beam with one that provides the extra strength needed for the revised design. The special shape needed for this hangar was sucessfully communicated to the engineers, but not the fact that is was necessary not to have a column erected in the open area of the unit. The unit is being designed for a special aircraft which requires additional wing clearance. Item B results from some variations in plans to allow for future growth. The original plans required the location of the electrical power source to be provided by the transformer located on the west side of the ramp. However, after some discussion between the airport manager, the electric company officials, and the engineers, a decision was made that the best source for electrical power for this hangar, when considering the future growth on the ramp, would be to use the east side transformer. The last change, item C, will result in a credit to the contract price of the unit by eliminating additional painting after the construction of the building has been completed. Since the metal building materials are treated and painted before shipment, the airport staff recommends not repainting the building after it has been constructed. The total increased cost of this change order is funded with a project contingency Attachments: Contract Review Form Two Originals of Change Order 1 Construction Contract Change Order 1. Owner 2.

Change order #2 is for a decrease in project costs of $3,263.72, and Change Order #3 increases the contract amount for $4,293.35. The increased costs for these Change Orders are funded with an approved project contingency. The change orders will cover the outstanding changes required from the contractor to complete our new 8 -bay T -Hangar. To simplify and update Change Order #2, Airport Staff requested that Garver Engineers revise two previously received change orders into a revised Change Order #2. Change Order #2 includes a credit for $4,800.00 for an item covered in the approved Change Order #1 which was not performed. A more economical alternative, which is Item C on the Change Order, was developed to replace this deficiency. Item B was incorporated to avoid problems we have had in our older units with the electric system. Items D, E, F, were items considered extravagant and were deleted or replaced with a more economical alternative. Item G was the result of a tenant's request to customize one of the unit for which he is to reimburse the airport for the cost. Change Order #3 results from changes required by the City's Engineering Department for revised plans for the installation of two fire hydrants. Engineering requested that the fire hydrants be located on different sites on the Airport, the water lines be buried deeper, and the materials used in the road cut and the width had to be changed.

The Engineer shall have the authority to suspend the work wholly, or in part, for such period or periods as he may deem necessary, due to unsuitable weather, or such other conditions as are considered unfavorable for the prosecution of the work, or for such time as is necessary due to the failure on the part of the Contractor to carry out orders given or perform any or all provisions of the contract. In the event that the Contractor is ordered by the Engineer, in writing, to suspend work for some unforeseen cause not otherwise provided for in the contract and over which the Contractor has no control, the Contractor may be reimbursed for actual money expended on the work during the period of shutdown. No allowance will be made for anticipated profits. The period of shutdown shall be computed from the effective date of the Engineer's order to suspend work to the effective date of the Engineer's order to resume the work. Claims for such compensation shall be filed with the Engineer within the time period stated in the Engineer's order to resume work. The Contractor shall submit with his/her claim information substantiating the amount shown on the claim. The Engineer will forward the Contractor's claim to the owner for consideration in accordance with local laws or ordinances. No provision of this article shall be construed as entitling the Contractor to compensation for delays due to inclement weather, for suspensions made at the request of the Contractor, or for any other delay provided for in the contract, plans, or specifications. If it should become necessary to suspend work for an indefinite period, the Contractor shall store all materials in such manner that they will not become an obstruction nor become damaged in any way. He shall take every precaution to prevent damage or deterioration of the work performed and provide for normal drainage of the work. The Contractor shall erect temporary structures where necessary to provide for traffic on, to, or from the airport. 80-07 DETERMINATION AND EXTENSION OF CONTRACT TIME. The number of calendar days allowed for completion of the work shall be stated in the proposal and contract and shall be known as the CONTRACT TIME. Should the contract time require extension for reasons beyond the Contractor's control, it shall be adjusted as follows: (a) CONTRACT TIME based on WORKING DAYS shall be calculated weekly by the Engineer. The Engineer will furnish the Contractor a copy of his/her weekly statement of the number of working days charged against the contract time during the week and the number of working days currently specified for completion of the contract (the original contract time plus the number of working days, if any, that have been included in approved CHANGE ORDERS or SUPPLEMENTAL AGREEMENTS covering EXTRA WORK). The Engineer shall base his/her weekly statement of contract time charged on the following considerations: GP -80-3 I (1) No time shall be charged for days on which the Contractor is unable to proceed with the principal item of work under construction at the time for at least 6 hours with the normal work force employed on such principal item. Should the normal work force be on a double -shift, 12 hours shall be used. Should the normal work force be on a triple -shift, 18 hours shall apply. Conditions beyond the Contractor's control such as strikes, lockouts, unusual delays in transportation, temporary suspension of the principal item of work under construction or temporary suspension of the entire work which have been ordered by the Engineer for reasons not the fault of the Contractor, shall not be charged against the contract time. , (2) The Engineer will not make charges against the contract time prior to the effective date of the notice to proceed. , (3) The Engineer will begin charges against the contract time on the first working day after the effective date of the notice to proceed. (4) The Engineer will not make charges against the contract time after the date of final ' acceptance as defined in the subsection titled FINAL ACCEPTANCE of Section 50. (5) The Contractor will be allowed 1 week in which to file a written protest setting forth his/her objections to the Engineer's weekly statement. If no objection is filed within such specified time, the weekly statement shall be considered as acceptable to the Contractor. The contract time (stated in the proposal) is based on the originally estimated quantities as described in the subsection titled INTERPRETATION OF ESTIMATED PROPOSAL QUANTITIES of Section 20. Should the satisfactory completion of the contract require ' performance of work in greater quantities than those estimated in the proposal, the contract time shall be increased in the same proportion as the cost of the actually completed quantities bears to the cost of the originally estimated quantities in the proposal. Such increase in contract time shall not consider either the cost of work or the extension of contract time that has been covered by change order or supplemental agreement and shall be made at the time of final payment. (b) CONTRACT TIME based on CALENDAR DAYS shall consist of the number of calendar days stated in the contract counting from the effective date of the notice to proceed and including all Saturdays, Sundays, holidays, and non -work days. All calendar days elapsing between the effective dates of the Engineer's orders to suspend and resume all work, due to causes not the fault of the Contractor, shall be excluded. I At the time of final payment, the contract time shall be increased in the same proportion as the cost of the actually completed quantities bears to the cost of the originally estimated quantities in the proposal. Such increase in the contract time shall not consider either cost of work or the extension of contract time that has been covered by a change order or supplemental agreement. ' Charges against the contract time will cease as of the date of final acceptance. GP -80-4 I I I II I I I IT I I I I I (b) Fails to perform the work or fails to provide sufficient workers, equipment or materials to I assure completion of work in accordance with the terms of the contract, or (c) When the contract time is a specified completion date, it shall be the date on which all contract work shall be substantially completed. If the Contractor finds it impossible for reasons beyond his/her control to complete the work within the contract time as specified, or as extended in accordance with the provisions of this subsection, he may, at any time prior to the expiration of the contract time as extended, make a written request to the Engineer for an extension of time setting forth the reasons which he believes will justify the granting of his/her request. The Contractor's plea that insufficient time was specified is not a valid reason for extension of time. If the Engineer finds that the work was delayed because of conditions beyond the control and without the fault of the Contractor, he may extend the time for completion in such amount as the conditions justify. The extended time for completion shall then be in full force and effect, the same as though it were the original time for completion. 80-08 FAILURE TO COMPLETE ON TIME. For each calendar day or working day, as specified in the contract, that any work remains uncompleted after the contract time (including all extensions and adjustments as provided in the subsection titled DETERMINATION AND EXTENSION OF CONTRACT TIME of this Section) the sum specified in the contract and proposal as liquidated damages will be deducted from any money due or to become due the Contractor or his/her surety. Such deducted sums shall not be deducted as a penalty but shall be considered as liquidation of a reasonable portion of damages that will be incurred by the owner should the Contractor fail to complete the work in the time provided in his/her contract. Permitting the Contractor to continue and finish the work or any part of it after the time fixed for its completion, or after the date to which the time for completion may have been extended, will in no way operate as a wavier on the part of the owner of any of its rights under the contract. 80-09 DEFAULT AND TERMINATION OF CONTRACT. The Contractor shall be considered in default of his/her contract and such default will be considered as cause for the owner to terminate the contract for any of the following reasons if the Contractor: (a) Fails to begin the work under the contract within the time specified in the "Notice to Proceed",or I (c) Performs the work unsuitably or neglects or refuses to remove materials or to perform anew such work as may be rejected as unacceptable and unsuitable, or (d) Discontinues the prosecution of the work, or CIiz:Zl1j F I I (e) Fails to resume work which has been discontinued within a reasonable time after notice to 1 do so, or (f) Becomes insolvent or is declared bankrupt, or commits any act of bankruptcy or 1 insolvency, or (g) Allows any final judgment to stand against him unsatisfied for a period of 10 days, or (h) Makes an assignment for the benefit of creditors, or I. (i) For any other cause whatsoever, fails to carry on the work in an acceptable manner. Should the Engineer consider the Contractor in default of the contract for any reason hereinbefore specified, he shall immediately give written notice to the Contractor and the Contractor's surety as to the reasons for considering the Contractor in default and the owner's intentions to terminate the contract. If the Contractor or surety, within a period of 10 days after such notice, does not proceed in 1 accordance therewith, then the owner will, upon written notification from the Engineer of the facts of such delay, neglect, or default and the Contractor's failure to comply with such notice, have full power and authority without violating the contract, to take the prosecution of the work out of the hands of the Contractor. The owner may appropriate or use any or all materials and equipment that have been mobilized for use in the work and are acceptable and may enter into an agreement for the completion of said contract according to the terms and provisions thereof, or use such other methods as in the opinion of the Engineer will be required for the completion of said contract in an acceptable manner. 1 All costs and charges incurred by the owner, together with the cost of completing the work under contract, will be deducted from any monies due or which may become due the Contractor. If such expense exceeds the sum which would have been payable under the contract, then the Contractor and the surety shall be liable and shall pay to the owner the amount of such excess. 80-10 TERMINATION FOR NATIONAL EMERGENCIES. The owner shall terminate the contract or portion thereof by written notice when the Contractor is prevented from proceeding with the construction contract as a direct result of an Executive Order of the President with respect to the prosecution of war or in the interest of national defense. When the contract, or any portion thereof, is terminated before completion of all items of work in the contract, payment will be made for the actual number of units or items of work completed at the contract price or as mutually agreed for items of work partially completed or not started. No claims or loss of anticipated profits shall be considered. Reimbursement for organization of the work, and other overhead expenses, (when not otherwise 1 GP -80-6 - I ' included in the contract) and moving equipment and materials to and from the job will be considered, the intent being that an equitable settlement will be made with the Contractor. Acceptable materials, obtained or ordered by the Contractor for the work and that are not incorporated in the work shall, at the option of the Contractor, be purchased from the Contractor ' at actual cost as shown by receipted bills and actual cost records at such points of delivery as may be designated by the Engineer. Termination of the contract or a portion thereof shall neither relieve the Contractor of his/her responsibilities for the completed work nor shall it relieve his/her surety of its obligation for and concerning any just claim arising out of the work performed. LI IH I I H I I I I END OF SECTION GP -80 GP -80-7 I SECTION 90 MEASUREMENT AND PAYMENT 90-01 MEASUREMENT OF QUANTITIES. All work completed under the contract will be measured by the Engineer, or his/her authorized representatives, using United States Customary Units of Measurement or the International System of Units. The method of measurement and computations to be used in determination of quantities of material furnished and of work performed under the contract will be those methods generally recognized as conforming to good engineering practice. Unless otherwise specified, longitudinal measurements for area computations will be made horizontally, and no deductions will be made for individual fixtures (or leave -outs) having an area of 9 square feet (0.8 square meter) or less. Unless otherwise specified, transverse measurements for area computations will be the neat dimensions shown on the plans or ordered in writing by the Engineer. Structures will be measured according to neat lines shown on the plans or as altered to fit field conditions. Unless otherwise specified, all contract items which are measured by the linear foot such as electrical ducts, conduits, pipe culverts, underdrains, and similar items shall be measured parallel to the base or foundation upon which such items are placed. ' In computing volumes of excavation the average end area method or other acceptable methods will be used. The thickness of plates and galvanized sheet used in the manufacture of corrugated metal pipe, metal plate pipe culverts and arches, and metal cribbing will be specified and measured in decimal fraction of inches. I Li I I [1 r The term "ton" will mean the short ton consisting of 2,000 pounds (907 kilograms) avoirdupois. All materials which are measured or proportioned by weights shall be weighed on accurate, approved scales by competent, qualified personnel at locations designed by the Engineer. If material is shipped by rail, the car weight may be accepted provided that only the actual weight of material be paid for. However, car weights will not be acceptable for material to be passed through mixing plants. Trucks used to haul material being paid for by weight shall be weighed empty daily at such times as the Engineer directs, and each truck shall bear a plainly legible identification mark. Materials to be measured by volume in the hauling vehicle shall be hauled in approved vehicles and measured therein at the point of delivery. Vehicles for this purpose may be of any size or type acceptable to the Engineer, provided that the body is of such shape that the actual contents may be readily and accurately determined. All vehicles shall be loaded to at least their water level capacity, and all loads shall be leveled when the vehicles arrive at the point of delivery. n GP -90-1 I When requested by the Contractor and approved by the Engineer in writing, material specified to be measured by the cubic yard (cubic meter) may be weighed, and such weights will be converted to cubic yards (cubic meters) for payment purposes. Factors for conversion from weight measurement to volume measurement will be determined by the Engineer and shall be agreed to by the Contractor before such method of measurement of pay quantities is used. Bituminous materials will be measured by the gallon (liter) or ton (kilogram). When measured ' by volume, such volumes will be measured at 60°F (15°C) or will be corrected to the volume at 60°F (15°C) using ASTM D 1250 for asphalts or ASTM D 633 for tars. Net certified scale weights or weights based on certified volumes in the case of rail shipments will be used as a basis of measurement, subject to correction when bituminous material has been lost from the car or the distributor, wasted, or otherwise not incorporated in the work. When bituminous materials are shipped by truck or transport, net certified weights by volume, subject to correction for loss or foaming, may be used for computing quantities. Cement will be measured by the ton (kilogram) or hundredweight (kilogram). ' Timber will be measured by the thousand feet board measure (M.F.B.M.) actually incorporated in the structure. Measurement will be based on nominal widths and thicknesses and the extreme length of each piece. The term "lump sum" when used as an item of payment will mean complete payment for the work described in the contract. When a complete structure or structural unit (in effect, "lump sum" work) is specified as the unit ' of measurement, the unit will be construed to include all necessary fittings and accessories. Rental of equipment will be measured by time in hours of actual working time and necessary traveling time of the equipment within the limits of the work. Special equipment ordered by the Engineer in connection with force account work will be measured as agreed in the change order or supplemental agreement authorizing such force account work as provided in the subsection titled PAYMENT FOR EXTRA AND FORCE ACCOUNT WORK of this section. When standard manufactured items are specified such as fence, wire, plates, rolled shapes, pipe conduit, etc., and these items are identified by gage, unit weight, section dimensions, etc., such identification will be considered to be nominal weights or dimensions. Unless more stringently controlled by tolerances in cited specifications, manufacturing tolerances established by the industries involved will be accepted. Scales for weighing materials which are required to be proportioned or measured and paid for by weight shall be furnished, erected, and maintained by the Contractor, or be certified permanently installed commercial scales. Scales shall be accurate within one-half percent of the correct weight throughout the range of use. The Contractor shall have the scales checked under the observation of the inspector before beginning work and at such other times as requested. The , GP -90-2 ' I intervals shall be uniform in spacing throughout the graduated or marked length of the beam or dial and shall not exceed one -tenth of 1 percent of the nominal rated capacity of the scale, but not less than 1 pound (454 grams). The use of spring balances will not be permitted. Beams, dials, platforms, and other scale equipment shall be so arranged that the operator and the inspector can safely and conveniently view them. Scale installations shall have available ten standard 50 -pound (2.3 kilogram) weights for testing the weighing equipment or suitable weights and devices for other approved equipment. Scales must be tested for accuracy and serviced before use at a new site. Platform scales shall be installed and maintained with the platform level and rigid bulkheads at each end. Scales "overweighing" (indicating more than correct weight) will not be permitted to operate, and all materials received subsequent to the last previous correct weighing -accuracy test will be reduced by the percentage of error in excess of one-half of 1 percent. In the event inspection reveals the scales have been "underweighing" (indicating less than correct weight), they shall be adjusted, and no additional payment to the Contractor will be allowed for ' materials previously weighed and recorded. All costs in connection with furnishing, installing, certifying, testing, and maintaining scales; for ' furnishing check weights and scale house; and for all other items specified in this subsection, for the weighing of materials for proportioning or payment, shall be included in the unit contract prices for the various items of the project. When the estimated quantities for a specific portion of the work are designated as the pay quantities in the contract, they shall be the final quantities for which payment for such specific portion of the work will be made, unless the dimensions of said portions of the work shown on the plans are revised by the Engineer. If revised dimensions result in an increase or decrease in the quantities of such work, the fmal quantities for payment will be revised in the amount 'represented by the authorized changes in the dimensions. ' 90-02 SCOPE OF PAYMENT. The Contractor shall receive and accept compensation provided for in the contract as full payment for furnishing all materials, for performing all work under the contract in a complete and acceptable manner, and for all risk, loss, damage, or expense of ' whatever character arising out of the nature of the work or the prosecution thereof, subject to the provisions of the subsection titled NO WAIVER OF LEGAL RIGHTS of Section 70. When the "basis of payment" subsection of a technical specification requires that the contract price (price bid) include compensation for certain work or material essential to the item, this same work or material will not also be measured for payment under any other contract item ' which may appear elsewhere in the contract, plans, or specifications. I I GP-90-3 H 90-03 COMPENSATION FOR ALTERED QUANTITIES. When the accepted quantities of work vary from the quantities in the proposal, the Contractor shall accept as payment in full, so far as contract items are concerned, payment at the original contract price for the accepted quantities of work actually completed and accepted. No allowance, except as provided for in the subsection titled ALTERATION OF WORK AND QUANTITIES of Section 40, will be made for any increased expense, loss of expected reimbursement, or loss of anticipated profits suffered or claimed by the Contractor which results directly from such alterations or indirectly from his/her unbalanced allocation of overhead and profit among the contract items, or from any other cause. 90-04 PAYMENT FOR OMITTED ITEMS. As specified in the subsection titled OMITTED ITEMS of Section 40, the Engineer shall have the right to omit from the work (order ' nonperformance) any contract item, except major contract items, in the best interest of the owner. Should the Engineer omit or order nonperformance of a contract item or portion of such item from the work, the Contractor shall accept payment in full at the contract prices for any work actually completed and acceptable prior to the Engineer's order to omit or• nonperform such contract item. Acceptable materials ordered by the Contractor or delivered on the work prior to the date of the Engineer's order will be paid for at the actual cost to the Contractor and shall thereupon become the property of the owner. In addition to the reimbursement hereinbefore provided, the Contractor shall be reimbursed for all actual costs incurred for the purpose of performing the omitted contract item prior to the date of the Engineer's order. Such additional costs incurred by the Contractor must be directly related to the deleted contract item and shall be supported by certified statements by the Contractor as to the nature and the amount of such costs. 90-05 PAYMENT FOR EXTRA AND FORCE ACCOUNT WORK. Extra work, performed in accordance with the subsection titled EXTRA WORK of Section 40, will be paid for at the contract prices or agreed prices specified in the change order or supplemental agreement paid for based on expended labor, equipment, and materials plus a negotiated and agreed upon allowance for overhead and profit. authorizing the extra work. When the change order or supplemental agreement authorizing the extra work requires that it be done by force account, such force. account shall be measured and a. Miscellaneous. No additional allowance will be made for general superintendence, the use of small tools, or other costs for which no specific allowance is herein provided. b. Comparison of Record. The Contractor and the Engineer shall compare records of the cost of force account work at the end of each day. Agreement shall be indicated by signature of the Contractor and the Engineer or their duly authorized representatives. c. Statement. No payment will be made for work performed on a force account basis until the Contractor has furnished the Engineer with duplicate itemized statements of the cost of GP -90-4 CI C C I I I I II C such force account work detailed as follows: (1) Name, classification, date, daily hours, total hours, rate and extension for each laborer and foreman. (2) Designation, dates, daily hours, total hours, rental rate, and extension for each unit of machinery and equipment. (3) Quantities of materials, prices, and extensions. (4) Transportation of materials. (5) Cost of property damage, liability and workman's compensation insurance premiums, unemployment insurance contributions, and social security tax. Statements shall be accompanied and supported by a receipted invoice for all materials used and transportation charges. However, if materials used on the force account work are not specifically purchased for such work but are taken from the Contractor's stock, then in lieu of the invoices the Contractor shall furnish an affidavit certifying that such materials were taken from his/her stock, that the quantity claimed was actually used, and that the price and transportation claimed represent the actual cost to the Contractor. ' 90-06 PARTIAL PAYMENTS. Partial payments will be made at least once each month as the work progresses. Said payments will be based upon estimates prepared by the Engineer of the value of the work performed and materials complete in place in accordance with the contract, plans, and specifications. Such partial payments may also include the delivered actual cost of those materials stockpiled and stored in accordance with the subsection titled PAYMENT FOR MATERIALS ON HAND of this section. I I C 1 I No partial payment will be made when the amount due the Contractor since the last estimate amounts to less than five hundred dollars. From the total of the amount determined to be payable on a partial payment, 10 percent of such total amount will be deducted and retained by the owner until the final payment is made, except as may be provided (at the Contractor's option) in the subsection titled PAYMENT OF WITHHELD FUNDS of this section. The balance (90 percent) of the amount payable, less all previous payments, shall be certified for payment. Should the Contractor exercise his/her option, as provided in the subsection titled PAYMENT OF- WITHHELD FUNDS of this section, no such 10 percent retainage shall be deducted. When not less than 95 percent of the work has been completed the Engineer may, at his/her discretion and with the consent of the surety, prepare an estimate from which will be retained an amount not less than twice the contract value or estimated cost, whichever is greater, of the work remaining to be done. The remainder, less all previous payments and deductions, will then be certified for payment to the Contractor. I GP -90-5 C It is understood and agreed that the Contractor shall not be entitled to demand or receive partial payment based on quantities of work in excess of those provided in the proposal or covered by approved change orders or supplemental agreements, except when such excess quantities have been determined by the Engineer to be a part of the final quantity for the item of work in question. No partial payment shall bind the owner to the acceptance of any materials or work in place as to quality or quantity. All partial payments are subject to correction at the time of final payment as provided in the subsection titled ACCEPTANCE AND FINAL PAYMENT of this section. 90-07 PAYMENT FOR MATERIALS ON HAND. Partial payments may be made to the extent of the delivered cost of materials to be incorporated in the work, provided that such materials meet the requirements of the contract, plans, and specifications and are delivered to acceptable sites on the airport property or at other sites in the vicinity that are acceptable to the owner. Such delivered costs of stored or stockpiled materials may be included in the next partial payment after the following conditions are met: (a) The material has been stored or stockpiled in a manner acceptable to the Engineer at or on an approved site. (b) The Contractor has furnished the Engineer with acceptable evidence of the quantity and quality of such stored or stockpiled materials. (c) The Contractor has furnished the Engineer with satisfactory evidence that the material and transportation costs have been paid. (d) The Contractor has furnished the owner legal title (free of liens or encumbrances of any kind) to the material so stored or stockpiled. (e) The Contractor has furnished the owner evidence that the material so stored or stockpiled is insured against loss by damage to or disappearance of such materials at anytime prior to use in the work. 1 It is understood and agreed that the transfer of title and the owner's payment for such stored or stockpiled materials shall in no way relieve the Contractor of his/her responsibility for furnishing and placing such materials in accordance with the requirements of the contract, plans, and specifications. In no case will the amount of partial payments for materials on hand exceed the contract price for such materials or the contract price for the contract item in which the material is intended to be used. No partial payment will be made for stored or stockpiled living or perishable plant materials. The Contractor shall bear all costs associated with the partial payment of stored or stockpiled materials in accordance with the provisions of this subsection. GP -90-6 1 I 90-08 PAYMENT OF WITHHELD FUNDS. At the Contractor's option, he/she may request that the owner accept (in lieu of the 10 percent retainage on partial payments described in the subsection titled PARTIAL PAYMENTS of this section) the Contractor's deposits in escrow under the following conditions. (a) The Contractor shall bear all expenses of establishing and maintaining an escrow account and escrow agreement acceptable to the owner. (b) The Contractor shall deposit to and maintain in such escrow only those securities or bank certificates of deposit as are acceptable to the owner and having a value not less than the 10 percent retainage that would otherwise be withheld from partial payment. (c) The Contractor shall enter into an escrow agreement satisfactory to the owner. (d) The Contractor shall obtain the written consent of the surety to such agreement. 90-09 ACCEPTANCE AND FINAL PAYMENT. When the contract work has been accepted in accordance with the requirements of the subsection titled FINAL ACCEPTANCE of Section 50, the Engineer will prepare the final estimate of the items of work actually performed. The Contractor shall approve the Engineer's final estimate or advise the Engineer of his/her objections to the final estimate which are based on disputes in measurements or computations of the final quantities to be paid under the contract as amended by change order or supplemental agreement. The Contractor and the Engineer shall resolve all disputes (if any) in the measurement and computation of final quantities to be paid within 30 calendar days of the ' Contractor's receipt of the Engineer's final estimate. If, after such 30 -day period, a dispute still exists, the Contractor may approve the Engineer's estimate under protest of the quantities in dispute, and such disputed quantities shall be considered by the owner as a claim in accordance ' with the subsection titled CLAIMS FOR ADJUSTMENT AND DISPUTES of Section 50. After the Contractor has approved, or approved under protest, the Engineer's final estimate, final ' payment will be processed based on the entire sum, or the undisputed sum in case of approval under protest, determined to be due the Contractor less all previous payments and all amounts to be deducted under the provisions of the contract. All prior partial estimates and payments shall 'be subject to correction in the final estimate and payment. ' If the Contractor has filed a claim for additional compensation under the provisions of the subsection titled CLAIMS FOR ADJUSTMENTS AND DISPUTES of Section 50 or under the - provisions of this subsection, such claims will be considered by the owner in accordance with ' local laws or ordinances. Upon final adjudication of such claims, any additional payment determined to be due the Contractor will be paid pursuant to a supplemental final estimate. I END OF SECTION GP -90 ' GP -90-7 [1 I I I I J I I 11 I J I I I I I SPECIAL CONDITIONS SC -01 GENERAL NOTES AND DESCRIPTION OF THE WORK. Detailed descriptions of the several items of work are given in the TECHNICAL SPECIFICATIONS that follow. In general, the work consists of the construction of an 8 Bay T -Hangar including connections to existing electrical service, and construction of approximately 525 feet of 6 -inch ductile iron water line. General Notes: 1. All of the work is within secure areas of the airport. Details of the Contractor's responsibility to maintain security of the airport are included in these Special Conditions of the Contract Documents. 2. All of the work will be accomplished adjacent to active aircraft movement areas, and aircraft access and safety through these areas will be maintained throughout the contract. 3. Underground utilities exist within and adjacent to the limits of construction. Existing utilities are not shown on the plans. Prior to beginning any type of excavation, the Contractor shall contact the utilities involved and make arrangements for the location of the utilities on the ground. The Contractor shall maintain the utility location markings until they are no longer necessary. Arkansas State Law, the Underground Facilities Damage Prevention Act, requires two working days advance notification through the Arkansas One -Call system center before excavating using mechanized equipment or explosives (except in the case of an emergency). The One -Call system phone number is 1-800-482-8998. The Contractor is advised that there is a severe penalty for not making this call. Not all utility companies are members of the Arkansas One -Call system; therefore, the Contractor is advised to contact all non- member utilities as well as the One -Call system. SC -02 SPECIAL INSTRUCTIONS. It is the intent of these instructions to minimize interference to airport operations; in areas not closed to aircraft, aircraft movement shall have the right of way over construction -related vehicles and equipment. The Contractor will be allowed access to the construction site only at the locations shown on the plans. The Contractor shall adhere to security requirements of Paragraph SC -08 of these Special Conditions. The Contractor shall be responsible for the maintenance and repair of each access/haul route. The Owner may have construction contract in progress, for the performance of other work, that bounds the limits of work for this project. The Contractor shall cooperate with the other II I Contractors on the Airport and shall conduct his work so as not to interfere with or hinder the progress of any other work being performed. ' SC -03 RESTRICTIONS ON TIME FOR WORK. 1. Airport Security is a primary concern of the Airport and the FAA. The Contractor's , access gates into the secured area of the Airport shall be kept guarded or locked at all times. 2. The intent of these contract documents is to organize and control the work so that it is ' accomplished with minimum inconvenience to the Airport and to insure the safety of aircraft movements at the Airport during the construction period. To accomplish this, the contractor's access to the airport is restricted to the immediate vicinity of the construction, and a direct, approved access route to the construction. All of the work accomplished on the terminal ramp is in the secure area of the airport, and the contractor shall comply with the Owner's rules and regulations for access to the secure area. 3. At all times aircraft movement shall have the right of way over the Contractor's equipment. 4. The Contractor will be allowed access to the construction areas at the locations ' indicated on the plans and as approved by the Owner. The Contractor shall be responsible for maintaining continuous security at each point of access. 5. The Contractor's work shall be phased to maintain access from the general aviation ramp to the runway. Before construction begins, the contractor shall submit a written schedule of construction for review and approval by the engineer and the owner. SC -04 INSURANCE. Insurance shall meet the following requirements: I. Contractor's Liability Insurance Requirements. The bidder shall provide with the Proposal a listing of both automobile and personal liability insurance coverage currently in force, along with a copy of a Certificate of Insurance as verification of that coverage. In addition, the bidder shall provide a statement of premium cost I issued by the agent or insurance carrier for that coverage. The kinds of insurance required are: (1) Public Liability; , SC -2 I I (2) Property Damage and Vehicle Liability (3) Workman's Compensation. (4) Third Party Insurance. ' Prior to the execution of the contract, the successful Bidder shall furnish, to the Owner, Certificate of Insurance coverages. During the life of the construction contract, the Contractor shall purchase and maintain comprehensive and general public liability insurance as is appropriate for the work being performed, as well as provide protection from claims which result from the Contractor's performance of the requirements of the contract documents. The insurance required by this section shall include the specific coverages and be written for not less than the limits of liability and coverages required by law. All such insurance shall remain in effect until the work is formally accepted by the Owner, and at all times thereafter that the Contractor may be correcting, removing, or replacing such work. The Contractor shall require all subcontractors on the job to carry insurance as I. outlined above, or shall furnish coverage for the subcontractors as outlined above. In the event the Owner determines that the low bidder's coverage in force is inadequate, the Owner may require the low bidder to procure additional coverage in amounts specified by the Owner. The cost of premiums for such additional coverage shall be paid by the low bidder. ' In the event the low bidder is unable, after diligent effort, to procure such additional coverage as may be required by the Owner, the Owner may, at his option, reduce the amount of additional coverage required or waive any requirement for additional coverage. ' 2. Third Party Coverage. In addition to the insurance described above, the Contractor also shall provide "Owner Protective" insurance which names as the insured the City of Fayetteville and Garver, Inc. Such insurance shall be in full force during ' the life of this Contract. SC -05 TIME FOR COMPLETION AND LIQUIDATED DAMAGES. The number of calendar days allowed for completion of the project is stipulated in the Proposal and in the ' Contract and shall be known as the Contract Time. ' SC -3 I I I It is understood and agreed by and between the Owner and the Contractor that the time of completion herein set out is a reasonable time. The Contractor shall perform fully, entirely and in an acceptable manner, the work contracted for within the contract time stated in the Contract. The construction contract performance time shall be counted from ten days after the effective date of the "Notice to Proceed", or the date work commences, whichever occurs first; and shall include all Sundays, holidays, and. non -work days. All calendar days elapsing between the effective dates , of any orders of the Engineer for suspension of the prosecution of the work, due to the fault of the Contractor, shall be counted as elapsed contract time, and shall not be considered for an extension of time. 2. Extensions of time for completion, under the condition of 2(a) next below, will be granted; extensions may be granted (in accordance with paragraph GP 80-07, DETERMINATION AND EXTENSION OF CONTRACT TIME) under other stated conditions: a. If the satisfactory execution and completion of the Contract shall require work or material in greater amounts or quantities than those set forth in the Contract, then the Contract time shall be increased in the same proportion as the additional work bears to the original work contracted for. b. Extensions of time may be granted if work is delayed for the owner's convenience. , c. An average or usual number of inclement weather days, when work cannot proceed, is to be anticipated during the construction period and is not to be considered as warranting extension of time. If, however, it appears that the Contractor is delayed by conditions of weather, times and seasons, so unusual as not to be reasonably anticipated, extensions of time may be granted. No extension of time for inclement weather days shall be granted after the Contract Time has expired. d. Should the work under the Contract be delayed by other causes which could not have been prevented or contemplated by the Contractor, and which are beyond the Contractor's power to prevent or remedy, an extension of time may be granted. Such causes of delay shall include but not necessarily be limited to the following: (1) Priority or allocation order duly issued by the Federal Government. ' (2) Acts of God, acts of the public enemy, fires, floods, epidemics, quarantine ' restrictions, freight embargoes, and unusually severe weather. (3) Any delays of Subcontractors or suppliers occasioned by any of the causes specified in (1) or (2) above. SC -4 I I ' 3. The amount of all extensions of time for whatever reason granted shall be determined by the Owner. In general, only actual and not hypothetical days of delay will be ' considered. The Owner shall have authority to grant additional extensions of time as the Owner may deem justifiable. The amount of Liquidated Damages to be assessed shall be $350 per day for each day ' over the total contract time stipulated in the Contract. 4. Time is an essential element of the Contract, and it is important that the work be pressed vigorously to completion. Loss will accrue to the public due to delayed completion of the facility and the cost to the Owner of the administration of the Contract, including engineering, construction observation, and supervision, will be increased as the time occupied in the work is lengthened. All additional costs incurred by the Owner for engineering (approx. $65/hour), construction observation ' (approx. $39/hour), and supervision (approx. $65/hour) shall be borne by the Contractor. 5. Should the Contractor fail to complete the work as set forth in the Specifications and within the time stipulated in the Contract, there shall be deducted the amount shown above, for each day of delay, from any monies due or which may thereafter become due him, not as a penalty, but as ascertained and liquidated damages. ' 6. Should the amount otherwise due the Contractor be less than the amount of such ascertained and liquidated damages, the Contractor and his Surety shall be liable to the Owner for such deficiency. ' 7. If the Contractor finds it impossible for reasons beyond his control to complete the work within the Contract time as specified, or as extended in accordance with the provisions of this subsection, he may, at any time prior to -the expiration of the Contract time as extended, make a written request to the Engineer for an extension of time setting forth the reasons which he believes will justify the granting of his request. The. Contractor's plea that insufficient time was specified is not a valid reason for extension of time. If the Engineer finds that the work was delayed because of conditions beyond the control and without the fault of the Contractor, he ' may recommend to the Owner that the contract time be extended as conditions justify. If the Owner extends the contract, the extended time for completion shall then be in full force and effect, the same as though it were the original time for completion. ' SC -06 LEGAL HOLIDAYS. January 1, Memorial Day, July 4, Labor Day, Thanksgiving and December 25 will be considered as being holidays; no other days will be so considered. ' SC -5 I No engineering supervision or construction observation (or inspection) will be furnished on legal holidays or Sundays, except in an emergency.

As a minimum, the Contractor shall provide I the following instrument control for the work: a. The Contractor shall set intermediate line and grade stakes and final grade ' stakes, "blue tops," as required to control the construction of shoulders, ditches and structures. , b. It shall be the duty of the Contractor and his employees to call to the attention of the Engineer any instrument control reference point which may have been , displaced or which seems to be off line or grade. c. The Contractor shall preserve carefully all bench marks, reference points, , stakes or marks. In case any such is displaced or destroyed willfully or carelessly by the Contractor's operations, the Contractor will be charged with the cost of its re-establishment, and he shall be responsible for any error in construction resulting from such displacement or destruction.

Any part of the plan that is unacceptable will be rejected and the Contractor shall submit changes for reevaluation. All approvals given by the Engineer shall be subject to trial and satisfactory performance in the field, and shall not relieve the Contractor of the responsibility to satisfactorily complete the work as detailed on the plans and in the specifications. MATERIALS. A. Concrete Materials. Materials for concrete shall conform to the , requirements of Section 03300: CAST -IN -PLACE CONCRETE, with the exception that no superplasticizers will be allowed. The minimum amount of cementitious material shall be 564 pounds per cubic yard. No fly ash will be allowed in the cementitious material. The water to cement ratio shall be in the range of 0.42 to 0.44. Coarse aggregate shall be Size No. 67. Fine aggregate shall consist of natural sand only. Final blend of coarse aggregate and fine aggregate shall render a well -graded mix free of any gap grading. B. Reinforcing Steel. All reinforcing steel shall conform to the requirements of Section 03300: CAST -IN -PLACE CONCRETE. CONSTRUCTION METHODS AND EQUIPMENT. A. Protection of Existing Structures. When the plans require drilled pier ' excavations within close proximity to existing structures or utilities, the Contractor shall take all reasonable precautions to prevent damage to such structures. This shall include newly constructed piers. If not otherwise provided for in the plans, the Contractor shall be solely responsible for evaluating the need for, design of, and providing all reasonable precautioirary features to prevent damage. These measures shall include, but are not limited to, selecting construction methods and procedures that will prevent caving of the pier excavation, and monitoring and controlling the vibrations from construction activities. B. General Methods and Equipment. The Contractor shall perform the , excavations required for the piers, through whatever materials encountered to the dimensions and elevations shown on the plans, or 02380-2 H fl Li otherwise required by the specifications, at no additional cost to the Owner. The Contractor's methods and equipment shall be suited for the intended purpose and the materials encountered. Drilled piers shall be constructed by either the dry method, wet method, ' casing method, or permanent casing method, as necessary to produce sound, curable concrete foundation piers free of defects. The permanent casing method shall be used only when authorized by the Engineer. The ' Contractor shall utilize a method on the basis of its suitability to the site conditions. ' Once approval is given to construct production piers, no changes will be permitted in the methods or equipment without written approval of the Engineer. C. Dry Construction Method. The dry construction method shall be used only at sites where the groundwater level and soil conditions are suitable Ito permit construction of the pier in a relatively dry excavation, and where the sides and bottom of the pier may be visually inspected by the Engineer prior to placing the concrete. The dry method consists of drilling the pier excavation, placing the reinforcing cage, and concreting the pier 'in a relatively dry excavation. The dry construction method shall be used only when less than 12 inches ' of water accumulates above the base over a one hour period when no pumping is permitted; the sides and bottom of the hole remain stable without caving, sloughing, or swelling over a four hour period immediately following completion of the excavation; and any loose material and water can be satisfactorily removed prior to inspection and prior to concrete placement. ' D. Wet Construction Method. The wet construction method shall be used at all sites where it is impractical to provide a dry excavation for placement of the pier concrete. The wet construction method consists of drilling the pier excavation below ' the water table, keeping the pier filled with water or mineral slurry, desanding or cleaning the slurry, final cleaning of the excavation by means of a bailing bucket, air lift, submersible pump or other approved devices, and placing the rebar cage and the pier concrete (with a tremie ,' or concrete pump beginning at the.pier bottom) which displaces the water or slurry as the pier is concreted. Temporary surface casing shall be ' provided to aid pier alignment and position and to prevent sloughing of the top of the pier, except when the Contractor demonstrates to the satisfaction of the Engineer that the surface casing is not required. ' The wet construction method may be used in combination with the dry method and temporary or permanent casing methods. 02380-3 LJ E. Casing Construction Method. The casing construction method may be used at sites when the dry or wet construction methods are inadequate to prevent hole caving or excessive deformation of the hole. In this method, the casing may be either placed in a predrilled hole if no caving, swelling, or yielding occurs, or advanced through the ground by twisting, driving, or vibration before being cleaned out. When a formation is reached that is nearly impervious, a casing shall be placed in the hole and seated in the nearly impervious formation. Drilling may proceed as with the dry method to the projected depth. If seepage occurs at this point, temporary casing may be advanced further to create the dry condition. In the event seepage conditions prevent use of the dry method, excavation shall be completed using wet methods. The placement of the concrete shall proceed as with the wet or dry method, except that the casing shall be withdrawn after the concrete is placed. When caving soils occur near the ground surface and/or if the top of the concrete for the drilled pier is below the ground surface, the Contractor shall set a suitable temporary removable surface casing. The minimum surface casing length shall be the length required to prevent caving of the surface soils and to aid in maintaining pier position and alignment. Predrilling with slurry and/or overreaming to the outside diameter of the casing may be acceptable if required to install the surface casing at some sites. , Where drilling is through materials having a tendency to cave, the drilling shall be advanced by drilling in a mineral slurry. In the event that a caving layer or layers are encountered that cannot be controlled by slurry, the Contractor shall. install temporary removable casing through such caving layer or layers. Overreaming to the outside diameter of the casing may be required. However, the final dimensions of the drilled pier shall not be altered to accommodate these construction practices unless approved by the Engineer. The Contractor shall take whatever steps are required to prevent caving during pier excavation including installation of deeper casings. If the Contractor elects to remove a casing and replace it with a longer casing through caving soils, he shall adequately stabilize the excavation with slurry or backfill the excavation. Other approved methods which will control the size of the excavation and protect the integrity of the foundation soils may be used to excavate through caving , layers. Before the casing is withdrawn, the level of fresh concrete shall be at such a level that the fluid trapped behind the casing is displaced upward. As the casing is withdrawn care shall be exercised to maintain the level of concrete within the casing so that the fluid trapped behind the casing is , displaced upward out of the pier excavation without mixing with or displacing the pier concrete. 02380-4 I F. Permanent Casing Method. The permanent casing method shall be used ' when required by the plans. In this method, a casing is driven to the prescribed depth before excavation begins. If full penetration cannot be attained, the Engineer may direct the excavation through the casing to be accomplished and the casing driven again until reaching the desired penetration. In some cases overreaming to the outside diameter of the casing may be required before driving the casing. The casing shall be cut off at the prescribed elevation upon reaching the proper construction sequence, and the remainder of the casing is left in place. G. Excavation and Drilling Equipment. The excavation and drilling ' equipment shall have adequate capacity including power, torque, and down thrust to excavate a hole of both the maximum diameter and to a depth 20 percent greater than the longest pier shown on the plans. The excavation and overreaming tools shall be of adequate design, size, and strength to perform the work shown on the plans or described herein. When the material encountered cannot be drilled using conventional ' earth augers with soil or rock teeth, drill buckets, and/or underreaming tools, the Contractor shall provide special drilling equipment including but not limited to: rock core barrels, rock tools, air tools, and other equipment ' as necessary to construct the pier excavation to size and depth required. Approval of the Engineer is required before excavation by blasting is permitted. Sidewall overreaming shall be required when the sidewall of the hole is determined by the Engineer to have either softened due to excavation ' methods, swelled due to delays in concreting, or degraded because of slurry cake build-up. Oven -earning thickness shall be a minimum of 1/2 inch and a maximum of 3 inches beyond the pier radius. Oveneaming ' may be accomplished with a grooving tool, overreaming bucket, or other approved equipment. The thickness and elevation of sidewall oven -earning shall be as directed by the Engineer. The Contractor shall • bear all costs associated with both sidewall overreaming and additional pier concrete placement. ' 4.01 EXCAVATIONS. A. General. Pier excavations shall be made at locations and to the top of ' pier elevations, estimated bottom of pier elevations, pier geometry and dimensions shown in the contract documents. The Contractor shall extend drilled pier tip elevations when the Soils Engineer determines that ' the material encountered during excavation is unsuitable and/or differs from that anticipated in the design of the drilled pier. ' 02380-5 I The Contractor shall maintain a drilling log during pier excavation. The log shall contain information such as: the description and approximate top and bottom elevation of each soil or rock strata, seepage or groundwater, and remarks. Any drilled pier concrete over the theoretical amount required to fill any excavations for the piers dimensioned on the plans shall be furnished at no additional cost to the Owner. The Contractor shall not permit workmen to enter the pier excavation for ' any reason unless: both a suitable size casing has been installed and the water level has been lowered and stabilized below the level to be occupied, and adequate safety equipment and procedures have been provided to workmen entering the excavation. B. Obstructions. Surface and subsurface obstructions at drilled pier locations shall be removed by the Contractor. Such obstructions may include man-made materials such as old concrete foundations, and natural materials such as boulders. Special procedures and/or tools shall , be employed by the Contractor after the hole cannot be advanced using conventional augers fitted with soil or rock teeth, drilling buckets and/or underreaming tools. Such special procedures/tools may include but are , not limited to: chisels, boulder breakers, core barrels, air tools, hand excavation, temporary casing, and increasing the hole diameter. Blasting shall not be permitted. ' Drilling tools which are lost in the excavation shall be promptly removed by the Contractor at not cost to the Owner. All costs due to lost tool removal shall be borne by the Contractor including, but not limited to, costs associated with hole degradation due to removal operations or the time the hole remains open. C. Exploration. The Contractor shall take soil samples or rock cores, where directed by the Engineer, to determine the soil character. Samples shall be extracted with a standard penetration test split spoon sampler or undisturbed sample (Shelby) tube. Rock cores, if required, shall be cut with an approved double or triple tube core barrel to a minimum of five (5) feet below the bottom of the drilled pier excavation at the time the pier excavation is approximately complete. The Engineer may require the depth of sampling or coring to be extended up to a total depth of 20 feet. Rock core and standard penetration test samples shall be measured, visually identified, and described on the Contractor's log. The samples shall be placed in suitable containers, identified by pier location, elevation, and project number, and delivered with the Contractor's field log to the Engineer within 24 hours after the exploration is completed. The Engineer will inspect the samples, or cores, and determine the final depth of required excavation based on his evaluation of the materials' suitability. Three (3) copies of the typed final Contractor log shall be 02380-6 I furnished to the Engineer at the time the pier excavation is completed and accepted. ' 5.01 CASINGS. IA. General: Casings shall be steel, smooth, clean, watertight, and of ample strength to withstand both handling and driving stresses and the pressure of both concrete and the surrounding earth materials. The outside ' diameter of casing shall not be less than the specified size of pier. No extra compensation will be allowed for concrete required to fill an oversized casing or oversized excavations. All casings, except permanent casing, shall be removed from the pier excavation. Any length of permanent casing installed below the pier cutoff elevations shall remain in place. When the pier is to extend above the ground or through a body of water, the portion exposed above the ground or through a body of water may be formed with removable casing, except when permanent casing is ' specified. Removable casing shall be stripped from the pier in a manner that will not damage the concrete. Casings can be removed when the concrete is cured for a full 72 hours; the pier concrete is not exposed to salt water or moving water for seven (7) days; and the concrete reaches a compressive strength of at least 2500 psi as determined from concrete cylinder tests. B. Temporary Casing. All subsurface casing shall be considered temporary unless specifically shown as permanent in the concrete documents. All ' temporary casing shall be removed. Telescoping, predrilling with slurry, and/or overreaming to beyond the outside diameter of the casing may be required to install the casing. If the contractor elects to remove a casing and substitute a longer or larger diameter casing through caving soils, the excavation shall be either ' stabilized with slurry or backfilled before the new casing is installed, as directed in 3.1.3.2. Other methods, as approved by the Engineer, may be used to control the stability of the excavation and protect the integrity of the foundation soils. When temporary casings which are to be removed become fouled or ' bound in the pier excavation and cannot be practically removed, and concreting has not yet begun, the Engineer may direct that the pier excavation be drilled deeper to compensate for the loss of capacity due to the presence of the casing. No additional compensation will be paid for the casing left in the excavation. No additional length of pier will be paid for beyond the current depth of excavation or the plan tip elevation of the production pier, whichever is lower. ' 02330-7 i� Temporary casings which become bound or fouled during concreting of the pier, and cannot be practically removed before the concrete begins to set up, shall constitute a defect in the drilled pier. The Contractor shall be responsible to improve such defective piers to the satisfaction of the Engineer. Improvements may consist of, but are not limited to, removing the pier concrete and extending the pier deeper to compensate for loss of frictional capacity in the cased zone, providing straddle piers to compensate for capacity loss, or providing replacement piers. All corrective measures, including redesign of footings or drilled pier caps, shall be performed to the satisfaction of the Engineer by the Contractor without either additional compensation or extension of Contract Time. No compensation will be paid for casing remaining in place. Any redesigns submitted must be approved in writing by the Engineer. Temporary casing extraction shall be at a slow, uniform rate, with the pull in line with the axis of the pier. At all times the elevation of the concrete in the casing shall be maintained high enough to displace the drilling slurry between the outside of the casing and the edge of the hole as the casing is removed. Temporary casings shall be removed while the concrete remains workable. No temporary casings will be removed if the concrete slump is less than four (4) inches. Should this condition occur, the pier will be designated as defective, and corrections to the situation , shall be as described above. Special casing systems may be used in open water areas, when approved, which are designed to permit removal after the concrete has hardened. Special casings shall be designed so that no damage occurs to the drilled pier concrete during their removal. C. Permanent Casings. Permanent casing shall be used when approved by the Engineer. The casing shall be continuous between top and bottom elevations prescribed on the plans or as directed by the Engineer. After installation is complete, the permanent casing shall be cut off at the prescribed elevation and the pier completed. In general, permanent casing shall not be placed in an overreamed pier hole. 6.01 SLURRY A. Mineral slurries shall be employed when slurry is used in the drilling process, unless other drilling fluids are approved in writing by the Engineer. The slurry shall have both a mineral grain size that will remain in suspension and sufficient viscosity and gel characteristics to transport excavated material to a suitable screening system. The percentage and specific gravity of the material used to make the suspension shall be sufficient to maintain the stability of the excavation and to allow proper concrete placement. During construction, the level of the slurry shall be 02380-8 ' H I maintained at a height sufficient to prevent caving of the hole. In the event of a sudden significant loss of slurry to the hole, the construction of that foundation shall be stopped until a method to stop slurry loss or an alternate construction procedure has been approved by the Engineer. The mineral slurry shall be premixed thoroughly with clean, fresh water, and an adequate time (as prescribed by the mineral manufacturer) shall be allotted for hydration, prior to introduction into the pier excavation. ' Slurry tanks of adequate capacity will be required for slurry circulation, storage, and treatment. No excavated slurry pits will be allowed in lieu of slurry tanks, without the written permission of the Engineer. Desanding ' equipment shall be provided by the Contractor as necessary to control slurry sand content to less than four percent (4%) by volume at any point in the borehole. The Contractor shall take all steps necessary to prevent ' the slurry from "setting up" in the pier. Such methods may include, but are not limited to: agitation, circulation, and/or adjusting the properties of the slurry. Disposal of all slurry shall be performed offsite in suitable ' areas by the Contractor, and subject to all environmental regulations pertaining to slurry disposal. I 7.01 EXCAVATION INSPECTION A. Contact the Engineer to inspect drilled piers before pouring I. concrete. B. The Contractor shall provide equipment for checking the dimensions and alignment of each permanent pier excavation. The dimensions and ' alignment shall be determined by the Contractor in the presence of the Engineer or his inspector. Final pier depths shall be measured with a weighted tape or other approved methods after final cleaning. Unless ' otherwise stated on the plans, a minimum of 50 percent of the base of each pier shall have less than 1/2 inch of sediment at the time of placement of the concrete. Pier cleanliness will be determined by the ' Engineer, by visual inspection for dry piers, or other methods deemed appropriate to the Engineer for wet piers. In addition,'for dry excavations, the maximum depth of water shall not exceed three (3) inches prior to concrete pour. Inspection of a pier excavation may be accomplished by any suitable ' method, including the use of video equipment or, in the case of a dry excavation, by personnel in the hole. Visual inspection by personnel in the hole requires safety measures that include, but are not limited to: (1) Usage of air sampling devices in the hole to check for volatile or poisonous gases, as well as oxygen content; (2) Providing proper ventilation to the excavation. No personnel will be allowed into the ' excavation until all local, state, and federal occupational safety regulations are adhered to. I r :i 5 I I 9.01 CONSTRUCTION TOLERANCES A. A. The following construction tolerances apply to drilled piers unless otherwise stated in the contract documents: The drilled pier shall be within three (3) inches of plan position in the horizontal plane at the plan elevation for the top of the pier. 2. The vertical alignment of a vertical pier excavation shall not vary from the plan alignment by more than 1/4 inch per foot of depth. 3. After all the concrete is placed, the top of the reinforcing steel cage shall not be more than three (3) inches below plan position. 4. All casing diameters shown on the plans refer to O.D. (outside diameter) dimensions. The dimensions of casings are subject to American Pipe Institute tolerances applicable to regular steel pipe. When approved, the Contractor may elect to provide a casing larger in diameter than shown on the plans. The top elevation of the pier shall have a tolerance of plus one inch or minus three inches from the plan top of pier elevation. 6. Excavation equipment and methods shall be designed so that the completed pier excavation will have a planar bottom. The cutting edges of excavation equipment shall be normal to the vertical axis of the equipment within a tolerance of 3/8 inch per foot of batter. Drilled pier excavations and completed piers not constructed within the required tolerances are unacceptable. The Contractor shall be responsible for correcting all unacceptable pier excavations and completed piers to the satisfaction of the Engineer. Materials and work necessary, including engineering analysis and redesign, to complete corrections for out of tolerance drilled piers excavations shall be furnished without either cost to the Owner or an extension of the completion dates of the project. Any redesign shall be performed by a professional engineer, registered in the State of Arkansas and engaged by the Contractor. Redesign drawings and computations prepared by the Contractor's engineer shall be signed and sealed. Out of tolerance pier holes shall be backfilled in an approved manner, when directed by the Engineer, until the redesign is complete and approved. STEEL CONSTRUCTION AND PLACEMENT The reinforcing steel cage, consisting of longitudinal bars, ties, cage stiffener bars, spacer, centralizers, and other necessary appurtenances, 02380-10 11 I I ,, [I I I [I I C H r I I I I shall be completely assembled and placed as a unit immediately after the pier excavation is inspected and accepted, and prior to concrete placement. Details of reinforcing steel will be as shown in the plans. The reinforcing steel in the pier shall be double -wire tied at all junctions and supported so that the reinforcing steel will remain within allowable tolerances given in 8.1 of this specification. Concrete spacers or other approved noncorrosive spacing devices shall be used at sufficient interval (near the bottom and at intervals not exceeding 10 feet up the pier to insure concentric spacing for the entire cage length. Spacers shall be constructed of approved material equal in quality and durability to the concrete specified for the pier. The spacers shall be of adequate dimension to insure a minimum three (3) inch annular space between the outside of the reinforcing cage and the side of the excavated hole. Approved cylindrical concrete feet (bottom supports) shall be provided to insure that the bottom of the cage is maintained the proper distance above the base. ' The elevation of the top of the steel cage shall be checked before and after the concrete is placed. If the rebar cage is not maintained within the specified tolerances, corrections shall be made by the Contractor to the ' satisfaction of the Engineer. No additional piers shall be constructed until the Contractor has modified his rebar cage support in a manner satisfactory to the Engineer. I [I I I I 11 I C I If the bottom of the excavated pier elevation is lower than the bottom of the pier elevation on the plans, all reinforcement required in the upper portion of the pier shall be achieved by splicing the additional length at the bottom of the cage, to avoid congestion in the upper portion of the pier. 10.01 CONCRETE PLACEMENT. A. General. Concrete for drilled piers shall have a minimum 28 -day compressive strength of 4000 psi. Concrete slump at the time of the pour shall be eight (8) inches. Additional slump requirements are defined below. Concrete temperature at the time of the pour shall not exceed 90° Fahrenheit. Concrete shall be placed as soon as possible after reinforcing steel placement, but in no case shall more than two (2) hours elapse between completion of the pier excavation and beginning of concrete placement. Concrete placement shall be continuous from the bottom to the top elevation of the pier. Concrete placement shall continue after the pier excavation is full until good quality concrete is evident at the top of the pier. Concrete shall be placed either through a tremie or concrete pump. 02380-11 I The elapsed time from the beginning of concrete placement in the pier to the completion of the placement shall not exceed four (4) hours, except as noted below. Retarders and/or water reducers in the concrete mix shall be adjusted as approved for the conditions encountered on the job, so that the concrete remains in a workable plastic state throughout the four hour placement limit. This is defined as a minimum slump of four (4) Inches existing everywhere within the concrete pier after placement has been completed. Prior to concrete placement, the Contractor shall provide test results of a trial mix, set time test (AASHTO T-197), and a slump loss test using approved methods, to demonstrate that the concrete meets this four hour requirement. These tests shall be conducted by an approved testing laboratory at temperatures and conditions similar to those at the job site at the time of the pier pour. However, the Contractor may request a longer placement time, provided he supplies a concrete mix that will maintain a slump of four (4) inches or greater over the longer placement time, as demonstrated by trial mix, set time, and slump loss tests. A slump loss test shall be conducted from the concrete at the site for verification of slump loss requirements, using a minimum batch size of four cubic yards of concrete. The Contractor shall place the concrete within the approved time and temperature limitations determined by the trial mix demonstration. B. Tremies. Tremies used for concrete placement in either wet or dry holes shall consist of a tube of sufficient length, weight, and diameter to discharge concrete at the pier base elevation. The tremie shall not contain aluminum parts which will have contact with the concrete. The tremie inside diameter shall be at least six (6) times the maximum size of aggregate used in the concrete mix but shall not be less than 10 inches. The inside and outside surfaces of the tremie shall be clean and smooth to permit both flow of concrete and unimpeded withdrawal during concreting. The wall thickness of the tremie shall be adequate to prevent crimping or sharp bends which restrict concrete placement. The tremie used for wet excavation concrete placement shall be watertight. Underwater placement shall not begin until the tremie is placed to the pier base elevation. Valves, bottom plates, or plugs may be used only if concrete discharge can begin within one tremie diameter of the base. Plugs and plates shall either be removed from the excavation or be of a material, approved by the Engineer, which will not cause a defect in the pier if not removed. The discharge end of the tremie shall be constructed to permit the free radial flow of concrete during placement operations. The tremie discharge end shall remain at the excavation bottom as long as possible, and thereafter be immersed at least two pier diameters but not less than 10 feet in concrete at all times after starting the flow of concrete. The flow of concrete shall be continuous. The concrete in the tremie shall be maintained at a positive pressure differential at all times to prevent water or slurry intrusion into the pier 02380-12 t I H I I J H H I H I 11 I I I I I C I concrete. If, at any time during the concrete pour in a wet excavation, the tremie line orifice is removed from the fluid concrete column and discharges concrete above the rising concrete level, the pier shall be considered defective. In such case, the Contractor shall remove the reinforcing cage and concrete, complete all necessary sidewall removal directed by the Engineer and repour the pier. All costs of replacement of defective piers shall be the responsibility of the Contractor. C. Pumping Concrete. Concrete pumps and lines may be used for concrete placement in either wet or dry excavations. All pump lines shall have a minimum five (5) inch diameter and be constructed with watertight joints. The use of aluminum pipe as a conveyance for the concrete will not be permitted. Concrete placement shall not begin until the pump line discharge orifice is at the pier base elevation. For wet excavations, a plug or similar device shall be used to separate the concrete from the fluid in the hole until pumping begins. The plug shall either be removed from the excavation or be of a material, approved by the Engineer, which will not cause a defect in the pier if not removed. The discharge orifice shall remain at least two pier diameters but not less than 10 feet below the surface of the fluid concrete at all times after starting the flow of concrete. When lifting the pump line during concreting, the Contractor shall temporarily reduce the line pressure until the orifice has been repositioned at a higher level in the excavation. If, at any time during the concrete pour, the pump line orifice is removed from the fluid concrete column and discharges concrete above the rising level, the pier shall be considered defective. In such case, the Contractor shall remove the reinforcing cage and concrete, complete all necessary sidewall removal directed by the Engineer and repour the pier. All costs of replacement of defective piers shall be the responsibility of the Contractor. 02380-13 J SECTION 03300 - CAST -IN -PLACE CONCRETE PART 1- GENERAL 1.1 RELATED DOCUMENTS: Drawings and general provisions of Contract apply to this Section. 1 1.2 DESCRIPTION OF WORK: This Section specifies cast -in place concrete, including formwork, reinforcing, mix design, placement procedures, and finishes. 1 13 • SUBMITTALS 1 A.
