In the latter case, CONTRACTOR may make the necessary corrections and resubmit the Applica- tion. Ten days after presentation of the Application for Pay- ment with ENGINEER's recommendation, the amount rec- ommended will (subject to the provisions of the last sentence of paragraph 14.7) become due and when due will be paid by OWNER to CONTRACTOR. 14.5. ENGINEER's recommendation of any payment requested in an Application for Payment will constitute a 26 L. I I I I I 1 I I I representation by ENGINEER to OWNER, based on ENGI- NEER's on -site observations of the Work in progress as an experienced and qualified design professional and on ENGI- NEER's review of the Application for Payment and the accompanying data and schedules that the Work has pro- gressed to the point indicated; that, to the best of ENGI- NEER's knowledge, information and belief, the quality of the Work is in accordance with the Contract Documents (subject to an evaluation of the Work as a functioning whole prior to or upon Substantial Completion, to the results of any subsequent tests called for in the Contract Documents, to a final determination of quantities and classifications for Unit Price Work under paragraph 9.10, and to any other qualifi- cations stated in the recommendation); and that CONTRAC- TOR is entitled to payment of the amount recommended. However, by recommending any such payment ENGINEER will not thereby be deemed to have represented that exhaus- tive or continuous on -site inspections have been made to check the quality or the quantity of the Work beyond the responsibilities specifically assigned to ENGINEER in the Contract Documents or that there may not be other matters or issues between the parties that might entitle CONTRAC- TOR to be paid additionally by OWNER or OWNER to withhold payment to CONTRACTOR. 14.6. ENGINEER's recommendation of final payment will constitute an additional representation by ENGINEER to OWNER that the conditions precedent to CONTRAC- TOR's being entitled to final payment as set forth in paragraph 14.13 have been fulfilled. 14.7. ENGINEER may refuse to recommend the whole or any part of any payment if, in ENGINEER's opinion, it would be incorrect to make such representations to OWNER. ENGINEER may also refuse to recommend any such pay- ment, or, because of subsequently discovered evidence or the results of subsequent inspections or tests, nullify any such payment previously recommended, to such extent as may be necessary in ENGINEER's opinion to protect OWNER from loss because: 14.7.1. the Work is defective, or completed Work has been damaged requiring correction or replacement, 14.7.2. the Contract Price has been reduced by Writ- ten Amendment or Change Order, 14.7.3. OWNER has been required to correct defec- tive Work or complete Work in accordance with paragraph 13.14, or 14.7.4. of ENGINEER's actual knowledge of the occurrence of any of the events enumerated in paragraphs 15.2.1 through 15.2.9 inclusive. OWNER may refuse to make payment of the full amount recommended by ENGINEER because claims have been made against OWNER on account of CONTRACTOR's per- formance or furnishing of the Work or Liens have been filed in connection with the Work or there are other items entitling OWNER to a set-off against the amount recommended, but OWNER must give CONTRACTOR immediate written notice (with a copy to ENGINEER) stating the reasons for such action. Substantial Completion: 14.8. When CONTRACTOR considers the entire Work ready for its intended use CONTRACTOR shall notify OWNER and ENGINEER in writing that the entire Work is substantially complete (except for items specifically listed by CONTRACTOR as incomplete) and request that ENGI- NEER issue a certificate of Substantial Completion. Within a reasonable time thereafter, OWNER, CONTRACTOR and ENGINEER shall make an inspection of the Work to deter- mine the status of completion. If ENGINEER does not con- sider the Work substantially complete, ENGINEER will notify CONTRACTOR in writing giving the reasons therefor. If ENGINEER considers the. Work substantially complete, ENGINEER will prepare and deliver to OWNER a tentative certificate of Substantial Completion which shall fix the date of Substantial Completion. There shall be attached to the certificate a tentative list of items to be completed or cor- rected before final payment. OWNER shall have seven days after receipt of the tentative certificate during which to make written objection to ENGINEER as to any provisions of the certificate or attached list. If, after considering such objec- tions, ENGINEER concludes that the Work is not substan- tially complete. ENGINEER will within fourteen days after submission of the tentative certificate to OWNER notify CONTRACTOR in writing, stating the reasons therefor. If, after consideration of OWNER's objections. ENGINEER considers the Work substantially complete, ENGINEER will within said fourteen days execute and deliver to OWNER and CONTRACTOR a definitive certificate of Substantial Completion (with a revised tentative list of items to be com- pleted or corrected) reflecting such changes from the tentative certificate as ENGINEER believes justified after consider- ation of any objections from OWNER. At the time of delivery. of the tentative certificate of Substantial Completion ENGI- NEER will deliverto OWNER and CONTRACTOR a written recommendation as to division of responsibilities pending final payment between OWNER and CONTRACTOR with respect to security, operation, safety, maintenance, heat, utilities, insurance and warranties. Unless OWNER and CONTRACTOR agree otherwise in writing and so inform ENGINEER prior to ENGINEER's issuing the definitive certificate of Substantial Completion, ENGINEER's afore- said recommendation will be binding on OWNER and CON- TRACTOR until final payment. 14.9. OWNER shall have the right to exclude CON- TRACTOR from the Work after the date of Substantial Com- pletion, but OWNER shall allow CONTRACTOR reasonable access to complete or correct items on the tentative list. Partial Utilization: 14.10. Use by OWNER of any finished part of the Work, which has specifically been identified in the Contract Docu- 27 I I 1 I I ments, or which OWNER, ENGINEER and CONTRAC- TOR agree constitutes a separately functioning and useable part of the Work that can be used by OWNER without sig- nificant interference with CONTRACTOR's performance of the remainder of the Work, may be accomplished prior to Substantial Completion of all the Work subject to the follow- ing: 14.10.1. OWNER at any time may request CON- TRACTOR in writing to permit OWNER to use any such part of the Work which OWNER believes to be ready for its intended use and substantially complete. If CON- TRACTOR agrees, CONTRACTOR will certify to OWNER and ENGINEER that said part of the Work is substantially complete and request ENGINEER to issue a certificate of Substantial Completion for that part of the Work. CON- TRACTOR at any time may notify OWNER and ENGI- NEER in writing that CONTRACTOR considers any such part of the Work ready for its intended use and substan- tially complete and request ENGINEER to issue a certif- icate of Substantial Completion for that part of the Work. Within a reasonable time after either such request, OWNER. CONTRACTOR and ENGINEER shall make an inspec- tion of that part of the Work to determine its status of completion. If ENGINEER does not consider that pan of the Work to be substantially complete, ENGINEER will notify OWNER and CONTRACTOR in writing giving the reasons therefor. If ENGINEER considers that part of the Work to be substantially complete, the provisions of para- graphs 14.8 and 14.9 will apply with respect to certification of Substantial Completion of that part of the Work and the division of responsibility in respect thereof and access thereto. 14.10.2. OWNER may at any time request CON- TRACTOR in writing to permit OWNER to take over operation of any such part of the Work although it is not substantially complete. A copy of such request will be sent to ENGINEER and within d reasonable time there- after OWNER. CONTRACTOR and ENGINEER shall make an inspection of that part of the Work to determine its status of completion and will prepare a list of the items remaining to be completed or corrected thereon before final payment. If CONTRACTOR does not object in writ- ing to OWNER and ENGINEER that such part of the Work is not ready for separate operation by OWNER. ENGINEER will finalize the list of items to be completed or corrected and will deliver such list to OWNER and CONTRACTOR together with a written recommendation as to the division of responsibilities pending final payment between OWNER and CONTRACTOR with respect to security, operation, safety, maintenance, utilities, insur- ance, warranties and guarantees for that part of the Work which will become binding upon OWNER and CON- TRACTOR at the time when OWNER takes over such operation (unless they shall have otherwise agreed in writ- ing and so informed ENGINEER). During such operation and prior to Substantial Completion of such part of the Work. OWNER shall allow CONTRACTOR reasonable access to complete or correct items on said list and to complete other related Work. 14.10.3. No occupancy or separate operation of part of the Work will be accomplished prior to compliance with the requirements of paragraph 5.15 in respect of property insurance. Final Inspection: 14.11. Upon written notice from CONTRACTOR that the entire Work or an agreed portion thereof is complete, ENGI- NEER will make a final inspection with OWNER and CON- TRACTOR and will notify CONTRACTOR in writing of all particulars in which this inspection reveals that the Work is incomplete or defective. CONTRACTOR shall immediately take such measures as are necessary to remedy such defi- ciencies. Final Application for Payment: 14.12. After CONTRACTOR has completed all such cor- rections to the satisfaction of ENGINEER and delivered all maintenance and operating instructions, schedules, guaran- tees. Bonds, certificates of inspection, marked -up record documents (as provided in paragraph 6.19) and other docu- ments —all as required by the Contract Documents, and after ENGINEER has indicated that the Work is acceptable (sub- ject to the provisions of paragraph 14.16). CONTRACTOR may make application for final payment following the pro- cedure for progress payments. The final Application for Pay- ment shall be accompanied by all documentation called for in the Contract Documents, together with complete and legally effective releases or waivers (satisfactory to OWNER) of all Liens arising out of or filed in connection with the Work. In lieu thereof and as approved by OWNER. CONTRACTOR may furnish receipts or releases in full; an affidavit of CON- TRACTOR that the releases and receipts include all labor. services, material and equipment for which a Lien could be filed, and that all payrolls. material and equipment bills, and other indebtedness connected with the Work for which OWNER or OWNER's property might in any way be respon- sible, have been paid or otherwise satisfied; and consent of the surety, if any, to final payment. If any Subcontractor or Supplier fails to furnish a release or receipt in full, CON- TRACTOR may furnish a Bond or other collateral satisfac- tory to OWNER to indemnify OWNER against any Lien. Final Payment and Acceptance: 14.13. If, on the basis of ENGINEER's observation of the Work during construction and final inspection, and ENGINEER's review of the final Application for Payment and accompanying documentation —all as required by the Contract Documents. ENGINEER is satisfied that the Work has been completed and CONTRACTOR's other obligations under the Contract Documents have been fulfilled. ENGI- NEER will, within ten days after receipt of the final Appli- cation for Payment, indicate in writing ENGINEER's rec- ommendation of payment and present the Application to OWNER for payment. Thereupon ENGINEER will give written notice to OWNER and CONTRACTOR that the Work is acceptable subject to the provisions of paragraph 14.16. I 28 I I I I I I I I I 1 I Otherwise, ENGINEER will return the Application to CON- TRACTOR, indicating in writing the reasons for refusing to recommend final payment, in which case CONTRACTOR shall make the necessary corrections and resubmit the Appli- cation.. Thirty days after presentation to OWNER of the Application and accompanying documentation, in appropri- ate form and substance, and with ENGINEER's recommen- dation and notice of acceptability, the amount recommended by ENGINEER will become due and will be paid by OWNER to CONTRACTOR. 14.14. If, through no fault of CONTRACTOR, final com- pletion of the Work is significantly delayed and if ENGI- NEER so confirms, OWNER shall, upon receipt of CON- TRACTOR's final Application for Payment and recommen- dation of ENGINEER, and without terminating the Agree- ment, make payment of the balance due for that portion of the Work fully completed and accepted. If the remaining balance to be held by OWNER for Work not fully completed or corrected is less than the retainage stipulated in the Agree- ment, and if Bonds have been furnished as required in para- graph 5.1, the written consent of the surety to the payment of the balance due for that portion of the Work fully com- pleted and accepted shall be submitted by CONTRACTOR to ENGINEER with theApplication for such payment. Such payment shall be made under the terms and conditions gov- erning final payment, except that it shall not constitute a waiver of claims. Contractor's Continuing Obligation: 14.15. CONTRACTOR's obligation to perform and com- plete the Work in accordance with the Contract Documents shall be absolute. Neither recommendation of any progress or final payment by ENGINEER, nor the issuance of a cer- tificate of Substantial Completion, nor any payment by OWNER to CONTRACTOR under the Contract Documents, nor any use or occupancy of the Work or any part thereof by OWNER, nor any act of acceptance by OWNER nor any failure to do so, nor any review and approval of a Shop Drawing or sample submission, nor the issuance of a notice of acceptability by ENGINEER pursuant to paragraph 14.13, nor ahy correction of defective Work by OWNER will con- stitute an acceptance of Work not in accordance with the Contract Documents or a release of CONTRACTOR's obli- gation to perform the Work in accordance with the Contract Documents (except as provided in paragraph 14.16). Waiver of Claims: 14.16. The making and acceptance of final payment will constitute: 14.16.1. a waiver of all claims by OWNER against CONTRACTOR, except claims arising from unsettled Liens, from defective Work appearing after final inspec- tion pursuant to paragraph 14.11 or from failure to comply with the Contract Documents or the terms of any special guarantees specified therein: however, it will not consti- tute a waiver by OWNER of any rights in respect of CONTRACTOR's continuing obligations under the Con- tract Documents: and 14.16.2. a waiver of all claims by CONTRACTOR against OWNER other than those previously made in writ- ing and still unsettled. ARTICLE 15 —SUSPENSION OF WORK AND TERMINATION Owner May Suspend Work: 15.1. OWNER may, at any time and without cause, sus- pend the Work or any portion thereof for a period of not more than ninety days by notice in writing to CONTRACTOR and ENGINEER which will fix the date on which Work will be resumed. CONTRACTOR shall resume the Work on the date so fixed. CONTRACTOR shall be allowed an increase in the Contract Price or an extension of the Contract Time, or both, directly attributable to any suspension if CONTRACTOR makes an approved claim therefor as provided in Articles 11 and 12. Owner May Terminate: 15.2. Upon the occurrence of any one or more of the following events: 15.2.1. if CONTRACTOR commences a voluntary case under any chapter of the Bankruptcy Code (Title 11, United States Code), as now or hereafter in effect, or if CON- TRACTOR takes any equivalent or similar action by filing a petition or otherwise under any other federal or state law in effect at such time relating to the bankruptcy or insolvency; 15.2.2. if a petition is filed against CONTRACTOR under any chapter of the Bankruptcy Code as now or hereafter in effect at the time of filing, or if a petition is filed seeking any such equivalent or similar relief against CONTRACTOR under any other federal or state law in effect at the time relating to bankruptcy or insolvency; 15.2.3. if CONTRACTOR makes a general assignment for the benefit of creditors; 15.2.4. if a trustee, receiver, custodian or agent of CONTRACTOR is appointed under applicable law or under contract, whose appointment or authority to take charge of property of CONTRACTOR is for the purpose of enforcing a Lien against such property or for the purpose of general administration of such property for the, benefit of CONTRACTOR's creditors; 152.5. if CONTRACTOR admits in writing an inabil- ity to pay its debts generally as they become due: 15.2.6. if CONTRACTOR persistently fails to perform the Work in accordance with the Contract Documents 1 29 I I I El I J I I 1 I (including, but not limited to, failure to supply sufficient skilled workers or suitable materials or equipment or failure to adhere to the progress schedule established under paragraph 2.9 as revised from time to time); 15.2.7. if CONTRACTOR disregards Laws or Regu- lations of any public body having jurisdiction; 15.2.8. if CONTRACTOR disregards the authority of ENGINEER; or 15.2.9. if CONTRACTOR- otherwise violates in any substantial way any provisions of the Contract Docu- ments; OWNER may, after giving CONTRACTOR (and the surety, if there be one) seven days' written notice and to the extent permitted by Laws and Regulations, terminate the services of CONTRACTOR, exclude CONTRACTOR from the site and take possession of the Work and of all CONTRACTOR's tools, appliances, construction equipment and machinery at the site and use the same to the full extent they could be used by CONTRACTOR (without liability to CONTRACTOR for trespass or conversion), incorporate in the Work all materials and equipment stored at the site or for which OWNER has paid CONTRACTOR but which are stored elsewhere, and finish the Work as OWNER may deem expedient. In such case CONTRACTOR shall not be entitled to receive any further payment until the Work is finished. If the unpaid balance of the Contract Price exceeds the direct, indirect and consequential costs of completing the Work (including but not limited to fees and charges of engineers, architects, attor- neys and other professionals and court and arbitration costs) such excess will be paid to CONTRACTOR. If such costs exceed such unpaid balance, CONTRACTOR shall pay the difference to OWNER. Such costs incurred by OWNER will be approved.as to reasonableness by ENGINEER and incor- porated in a Change Order, but when exercising any rights or remedies under this paragraph OWNER shall not be required to obtain the lowest price for the Work performed. • 15.3. Where CONTRACTOR's services have been so terminated by OWNER, the termination will not affect any rights or remedies of OWNER against CONTRACTOR then existing or which may thereafter accrue. Any retention or payment of moneys due CONTRACTOR by OWNER will not release CONTRACTOR from liability. 15.4. Upon seven days' written notice to CONTRAC- TOR and ENGINEER, OWNER may, without cause and without prejudice to any other right or remedy, elect to aban- don the Work and terminate the Agreement. In such case. CONTRACTOR shall be paid for all Work executed and any expense sustained plus reasonable termination expenses, which will include, but not be limited to, direct, indirect and con- sequential costs (including, but not limited to, fees and charges of engineers, architects, attorneys and other professionals and court and arbitration costs). Contractor May Stop Work or Terminate: 15.5. If, through no act or fault of CONTRACTOR, the Work is suspended for a period of more than ninety days by OWNER or under an order of court or other public authority, or ENGINEER fails to act on any Application for Payment within thirty days after it is submitted, or OWNER fails for thirty days to pay CONTRACTOR any sum finally deter- mined to be due, then CONTRACTOR may, upon seven days' written notice to OWNER and ENGINEER, terminate the Agreement and recover from OWNER payment for all Work executed and any expense sustained plus reasonable termination expenses. In addition and in lieu of terminating the Agreement, if ENGINEER has failed to act on an Appli- cation for Payment or OWNER has failed to make any pay- ment as aforesaid, CONTRACTOR may upon seven days' written notice to OWNER and ENGINEER stop the Work until payment of all amounts then due. The provisions of this paragraph shall not relieve CONTRACTOR of the obligations under paragraph 6.29 to carry on the Work in accordance with the progress schedule and without delay during disputes and disagreements with OWNER.

All claims, disputes and other matters in question between OWNER and CONTRACTOR arising out of, or relating to the Contract Documents or the breach thereof (except for claims which have been waived by the making or acceptance of final payment as provided by paragraph 14.16) will be decided by arbitration in accordance with the Con- struction Industry Arbitration Rules of the American Arbi- tration Association then obtaining subject to the limitations of this Article 16. This agreement so to arbitrate and any other agreement or consent to arbitrate entered into in accor- dance herewith as provided in this Article 16 will be specifi- cally enforceable under the prevailing law of any court having jurisdiction. -- 16.2. No demand for arbitration of any claim, dispute or other matter that is required to be referred to ENGINEER initially for decision in accordance with paragraph 9.11 will be made until the earlier of (a) the date on which ENGINEER has rendered a decision or (b) the tenth day after the parties have presented their evidence to ENGINEER if a written decision has not been rendered by ENGINEER before that date. No demand for arbitration of any such claim, dispute or other matter will be made later than thirty days after the date on which ENGINEER has rendered a written decision in respect thereof in accordance with paragraph 9.11; and the failure to demand arbitration within said thirty days' period shall result in ENGINEER's decision being final and binding upon OWNER and CONTRACTOR. If ENGINEER renders a decision after arbitration proceedings have been initiated. such decision may be entered as evidence but will not supersede the arbitration proceedings, except where the decision is acceptable to the parties concerned. No'demand for arbitra- tion of any written decision of ENGINEER rendered in accordance with paragraph 9.10 will be made later than ten days after the party making such demand has delivered writ- ten notice of intention to appeal as provided in paragraph 9.10. 16.3. Notice of the demand for arbitration will be filed in writing with the other party to the Agreement and with the American Arbitration Association, and a copy will be sent to ENGINEER for information. The demand for arbitration will be made within the thirty -day or ten-day period specified in paragraph 16.2 as applicable, and in all other cases within a reasonable time after the claim, dispute or other matter in question has arisen, and in no event shall any such demand be made after the date when institution of legal or equitable proceedings based on such claim, dispute or other matter in question would be barred by the applicable statute of limi- tations. 16.4. No arbitration arising out of or relating to the Con- tract Documents shall include by consolidation, joinder or in any other manner any other person or entity (including ENGINEER, ENGINEER's agents, employees or consul- tants) who is not a party to this contract unless: . 16.4.1. the inclusion of such other person or entity is necessary if complete relief is to be afforded among those who are already parties to the arbitration, 16.4.2. such other person or entity is substantially involved in a question of law or fact which is common to those who are already parties to the arbitration and which will arise in such proceedings, and 16.4.3. the written consent of the other person or entity sought to be included and of OWNER and CONTRAC- TOR has been obtained for such inclusion, which consent shall make specific reference to this paragraph: but no such consent shall constitute consent to arbitration of any dispute not specifically described in such consent or to arbitration with any party not specifically identified in such consent. 16.5. The award rendered by the arbitrators will be final, judgment may be entered upon it in any court having juris- diction thereof, and will not be subject to modification or appeal except to the extent permitted by Sections 10 and II of the Federal Arbitration Act (9 U.S.C. §§10,11).

The proportions shall be selected to produce an average strength at 28 days exceeding the specified compressive strength by the amount indicated below, when both air content and slump are the maximums permitted by the Specifications. If watertight concrete is required, the water -cement ratio shall not exceed 0.48. Determination of the required average strength shall be in accordance with ACI 318 "Building Code Requirements for Reinforced Concrete," except that if suitable data from trial batches or field experience cannot be obtained, permission will not be granted to base concrete proportions on the water -cement ratio limits set out in the above referenced code. a. Past Plant Performance. Proportions may be established on the actual field performance of the ready -mix producer. Where the concrete production facility has a record, based on at , least 30 consecutive strength tests representing similar materials and conditions to those expected, the strength used as the basis for selecting proportions shall exceed the required f'c by at least: 400 psi if the standard deviation is less than 300 psi; 550 psi if the standard deviation is 300 to 400 psi; 700 psi if the standard deviation is 400 to 500 psi; 900 psi if the standard deviation is 500 to 600 psi; 1,200 psi if the standard deviation is above 600 psi ' or unknown. Strength data for determining standard deviation shall be considered to comply with the foregoing stipulations if they represent either a group of at least 30 consecutive tests or the statistical average for two groups totaling 30 or more tests. The tests used to establish standard deviation shall represent concrete procuced to meet a specified strength or strengths within 1,000 psi of that specified for the proposed work. Changes in materials and proportions within the population of background tests shall not have been more closely restricted than they will be for the proposed work. Laboratory Trial Batches. When the ready -mix producer does not have a record of past performance, the combination of materials and the proportions selected shall be determined from trial mixes having proportions and consistencies suitable for the work based on ACI 211.1-77. When laboratory trial batches are used as the basis for selecting 500-6 1 Section 500 Concrete concrete proportions„ strength tests shall be made in accordance with "Method- ofTest for Compressive Strength of Molded Concrete Cylinders" (ASTM C39) on specimens prepared in accordance with "Method of Making and Curing Test Specimens in the Laboratory" (ASTM C192). A curve shall be established showing the relationship between water -cement ratio (or cement content) and compressive strength. The curve shall be based on at least three points representing batches which produce strengths above and below that required. Each point shall represent the average of at least three specimens tested at 28 days or the earlier age designation. The .average strength required shall exceed the specified Dcompressive strength by 1,200 psi. The maximum permissible water -cement ratio (or minimum cement content) for the concrete to be used in the structure shall be that shown by the curve to produce the average strength indicated, but in no case shall the water -cement ratio exceed 0.53 by weight, or in the case watertight concrete is specified or shown on the Plans, it shall in no case exceed 0.48 by weight. F. .SUBMITTALS The Contractor or ready -mix concrete producer shall submit either: 1. one copy of each of 30 consecutive strength test results and mix design used from a record of past performance; or 2. one copy of the laboratory trial mix designs and results, and one copy of the mix design proposed for use under this contract. The Contractor shall provide and pay all costs associated with testing o services for the following: 1. any testing service required by the Contractor; and 2. qualification of the proposed materials and the_ establishment of mix designs in accordance with AC! 318, latest revision, and these Specifications. ItAdditionally, when requested by the Engineer, the Contractor shall, at his own expense, submit samples of materials proposed for use in the concrete a. mix, including names, sources, and descriptions. 11 G. TESTING ;m. Materials and operations shall be tested as the work progresses. The cost of all field testing of materials and work shall be borne by the Contractor. The testing laboratory shall be one recommended by the Contractor and approved by the Engineer. 1. Testing will be performed generally as set out below. For each 50 cubic yards of concrete placed or for each run representing a unit or portion 500-7 Section 500 Concrete of a finished structure, whichever is less (i.e, footing, wall, floor slab, columns, roof slab, etc.), the following tests shall be performed: a. Composite samples shall be served in accordance with ASTM C172-71 (Reapproved 1977) "Standard Method of Sampling Fresh Concrete." b. Mold and laboratory cure three specimens from each test required in i accordance with ANSI/ASTM C31-69 (Reapproved 1975) "Standard Method of Making and Curing Concrete Test Specimens in the Field." c. Test the specimens in accordance with ANSI/ASTM C39-72 (Reapproved 1979) "Standard Test Method for Compressive Strength of Concrete Specimens." Two specimens shall be tested at 28 days for acceptance and one specimen shall be tested at seven days for information. d. The slump of the normal -weight concrete sample for each strength , test shall be determined in accordance with ANSI/ASTM C143-78 "Standard Test Method for Slump of Portland Cement Concrete." e. Determine the total air content of a normal -weight concrete sample for each strength test in accordance with ANSI/ASTM C238-83 "Standard Test Method for Air Content of Freshly Mixed Concrete by the Pressure Method," or in accordance with ANSI/ASTM C138-77 "Standard Test Method for Unit Weight, Yield, and Air Content (Gravimetric) of Concrete." 2. The Contractor, at his option, and under the direction of the Engineer, may secure and mold samples and perform the tests specified in ASTM C238-83, provided he has the necessary equipment for securing, molding and testing as set out in the referenced standards, and performs these tasks in strict accordance with the referenced standards. Any questions arising as to whether the tests are being performed in accordance with these standards, or whether an approved laboratory should be used, will be decided by the Engineer. H. EVALUATION AND ACCEPTANCE OF CONCRETE ' 1. Strength Level. The strength level of the concrete shall be considered satisfactory if both of the following requirements are met: I a. The average of all sets of three consecutive strength tests equal or exceed the specified f'c. b. No individual strength test (average of two cylinders) falls below required f'c by more than 500 psi. If either of the above requirements are not met, steps shall be taken immediately to increase the average of subsequent strength test results. If any strength test of laboratory -cured cylinders falls below required , f'c by more than 500 psi, steps shall be taken to assure that load -carrying capacity of the structure is not jeopardized. 500-8 1 Section 500 Concrete If the likelihood of21:ow-strength concrete is confirmed -and computations indicate that load -carrying capacity may have been significantly reduced, tests of cores drilled from the area in question may be required in accordance with "Method of Obtaining and Testing Drilled Cores and Sawed Beams of Concrete" (ASTM C42). In such case, three ii cores shall be taken for each strength test more than 500 psi below required f'c. If concrete in the structure will be dry under service conditions, cores shall be air dried (temperature 60° to 80° F., relative humidity less than 60.percent) for seven days before test and shall be tested dry. If concrete in the structure will be more than superficially wet under - service conditions, cores shall be immersed in water for at least 48 hours and be tested wet. Concrete in an area represented by core tests shall be considered structurally adequate if the average of three cores is equal to at least 85 percent of f'c and in no single core is less than 75 percent of f'c. To check testing accuracy, locations represented by erratic core strengths may be retested. If these criteria are not met, and if structural adequacy remains in doubt, the Engineer may order load tests for.the questionable portion of the structure, or take other action as flhe deems necessary, including non -acceptance of the structure. The cost of any additional testing to determine structural adequacy a. shall be borne by the Contractor. 2. Field -Cured Specimens. The.Engineer may require supplementary strength tests of cylinders cured under field conditions when the adequacy of curing and protection of concrete in the structure is in question. Field -cured cylinders shall be cured under field conditions in accordance with Section 7.4 of "Method of Making and Curing Concrete Test Specimens in the Field" (ASTM C31). Field -cured test cylinders shall be molded at the same time and from the same samples as.laboratory-cured test cylinders. Procedures for protecting and curing concrete shall be improved when strength of field -cured cylinders at the test age designated for measuring f'c is less than 85•percent of that of companion laboratory - cured cylinders. When laboratory -cured cylinder strengths are appreciably higher than f'c, field -cured cylinder strengths need not exceed f'c by more than 500 psi even though the 85 percent criterion is not met. The cost of obtaining samples, transportation and testing shall be borne by the Contractor. I. MIXING, PLACING AND CURING CONCRETE IIAll concrete shall be produced, mixed and delivered to the job site by a ready -mix- concrete manufacturer. The Engineer will consider site mixing of I 500-9 Section 500 Concrete concrete at the request of the Contractor. placed as set out below. I Concrete shall be mixed and I Before concrete is placed, all equipment for mixing and transporting the concrete shall be clean, all debris and ice shall be removed from the spaces to be occupied by the concrete, forms shall be properly coated, masonry filler units that will be in contact with concrete shall be well drenched, and the reinforcement shall be thoroughly clean of ice or other deleterious coatings. Water shall be removed from the place of deposit before concrete is placed unless a tremie is to be used or unless otherwise permitted by the Engineer. All laitance and other unsound material shall be removed from hardened concrete before additional concrete is placed. 1. Mixing of Concrete. All concrete shall be mixed until there is a uniform distribution of the materials and shall be discharged completely before the mixer is recharged. Ready -mixed concrete shall be mixed and delivered in accordance with the requirements set forth in "Specification for Ready -Mixed Concrete" (ASTM C94). 2. Conveying. Concrete shall be conveyed from the mixer to the place of final deposit by methods which will prevent segregation or loss of materials. Conveying equipment shall be capable of providing a supply of concrete at the site of placement without separation of• ingredients and without interruptions sufficient to permit loss of plasticity between successive increments. 3. Depositing. Concrete shall be deposited as nearly as practicable in its final position to avoid segregation due to rehandling or flowing. The concreting shall be carried on at such a rate that the concrete is at all times plastic and will readily fill the spaces between the bars when vibrated as herein specified. No concrete that has partially hardened or been contaminated by foreign materials shall be deposited in the structure, nor shall retempered concrete or concrete which has been remixed after initial set be used. In placing, concrete shall not be allowed to drop a distance of more than six (6) feet through free space. Tremies shall be used where the drop exceeds six feet. After concreting is started, it shall be carried on as a continuous operation until the placing of the panel or section is completed. The top surfaces of vertically formed lifts shall be generally level. In no case shall any concrete be placed without an Inspector present. Concrete placed in violation of this provision may be rejected and removal required. I I I I I I I r I I [] 1] I I I I 500-10 I 11 II II. I t it All concrete shall;Pbe thoroughly during placement,` and shall reinforcement and embedded fixture Section 500 Concrete s consolidated by mechanical vibration be thoroughly worked around the and into the corners of the forms. All vibration shall be internal and vibrating equipment shall be suitable to the Engineer. The Contractor shall provide a sufficient number of vibrators to properly compact each batch immediately after it is, placed in the forms, and shall have in reserve at all times sufficient vibratory equipment to guard against shutdown of the work because of the failure of equipment in operation. 4. Curing. Concrete shall be maintained above 50° F. and in a moist • condition for at least the first seven days after placing, except that high -early -strength concrete shall be so maintained for at least the first three days. Supplementary strength tests in accordance with Section 800-H.2 may be required to assure that curing is satisfactory. Curing by high pressure steam, steam at atmospheric pressure; heat and moisture, or other processes acceptable to the Engineer may be employed. Curing compounds, Visqueen, or burlene may be used if approved by the Engineer.. Accelerated curing shall provide the compressive strength of the concrete at the load stage considered at least equal to the design strength required at that load stage. The curing process shall produce concrete with a durability at least equivalent to the curing method if steam or other acceptable methods are not utilized. a. Cold -Weather Requirements. Adequate for heating concrete materials and freezing or near -freezing weather. materials containing snow or ice shall equipment shall be provided protecting concrete during No frozen materials or be used. All reinforcement, forms, fillers, and ground with which the concrete is to come in contact shall be free from snow and ice. All concrete placed in forms shall have a temperature of 50° F. or higher after placement. Adequate means shall be provided for maintaining this temperature for three days. When high -early -strength concrete is used, a temperature of at least 50° F. shall be maintained for two days. In either case, additional time necessary to ensure proper curing of the concrete shall be provided as directed by the Engineer. The housing, covering, or other protection used in curing shall remain intact at least 24 hours after artificial heating is discontinued. No dependence shall be placed on salt or other chemicals for the prevention of freezing. b. Hot -Weather Requirements. In hot weather, suitable precautions shall be taken to avoid drying of the concrete prior to finishing operations. Use of windbreaks, sunshades, fog sprays, or other devices as directed by the Engineer shall be provided. Concrete deposited in hot weather shall not have a placing temperature that will cause difficulty from loss of slump, flash 500-11 Section 500 Concrete set, or cold joints. Concrete temperature shall be less than 900 F. unless higher temperatures are permitted by the Engineer. FORMS Forms shall conform to shapes, lines and dimensions of the members as called for on the Plans, and shall be sufficiently tight to prevent leakage of mortar. They shall be properly braced or tied together so as to maintain position and shape. Unless otherwise specified, suitable moulding or bevel strips shall be placed in the angles of forms to round or bevel the edges of the concrete, as shown on the Plans or otherwise directed by the Engineer. Forms shall be removed in such a manner as to ensure the complete safety of the structure. In no case shall supporting forms or shoring be removed until members have acquired sufficient strength to support their weight and imposed loads safely. K. DEPOSITING CONCRETE UNDER WATER Concrete shall not be deposited in water except with the approval of the Engineer, and under his immediate supervision; and in this case, the method of placing shall be as hereinafter designated. Concrete deposited in water shall be a seal or watertight concrete. To ' prevent segregation, it shall be carefully placed in a compact mass, in its final position, by means of a tremie, a bottom dump bucket or other approved method, and shall not be disturbed after being deposited. Still water shall be maintained at the point of deposit and the forms under water shall be watertight. For parts of structures under water, when possible, concrete seals shall be 1 placed continuously from start to finish. The surface of the concrete shall be kept as nearly horizontal as practicable at all times. To ensure thorough bonding, each succeeding layer of seal shall be placed before the preceding layer has taken initial set. A tremie shall consist of a tube having a diameter of not less than I 10 inches, constructed in sections having flanged couplings fitted with gaskets. The tremies shall be supported so as to permit free movement of the discharge end over the entire top surface of the work and so as to permit rapid lowering when necessary to retard or stop the flow of concrete. The discharge end shall be closed at the start of work so as to prevent water entering the tube and shall be entirely sealed at all times. The tremie tube shall be kept full to the bottom of the hopper. When a batch is dumped into the hopper, the flow of concrete shall be induced by slightly raising the discharge end, always keeping it in the deposited concrete. The flow shall be continuous until the work is completed. Depositing of concrete by the drop bottom bucket method shall conform to the following specification. The top of the bucket shall be open. the bottom door shall open freely and outward when tripping. The bucket shall be completely filled and slowly lowered to avoid backwash. It shall not be r- 500-12 1 ft Section 500 Concrete !! dumped until it rests on the surface .upoh.= which the concrete is to be deposited and when discharged, shall•be withdrawn slowly until well above the concrete. The slump of concrete shall be maintained between.4 and 8 inches. Dewatering may proceed when the concrete seal is sufficiently hard and strong. .All laitance or other unsatisfactory materials shall be removed from the exposed surface by scraping, chipping•or other means which will not injure: the surface of the concrete. ftL. FALSEWORK AND CENTERING Unless otherwise provided, detailed Plans for falsework or centering shall be supplied to the Engineer on request; but, in no case shall the Contractor be relieved, of responsibility for results obtained by the use of these Plans. I. For designing falsework and centering, a weight of 150 pounds per cubic foot shall be assumed for green concrete. All falsework shall be designed and constructed to provide •the necessary rigidity and to .support the loads without appreciable settlement or deformation. The Engineer may require the Contractor to employ. screw jacks or hardwood wedges to take up any settlement in the formwork either before or during the placing of concrete. Falsework which cannot be founded on a satisfactory footing shall be supported on piling which shall be spaced, driven and removed in a manner approved by the Engineer. a, Falsework shall be set to give the finished structure the camber specified or indicated on the Plans. Arch centering shall be constructed according to centering plans approved by the Engineer. Provision shall be made by means of suitable wedges, sand boxes or other devices for the gradual lowering of centers, and rendering the arch self-supporting. When directed, centering shall be placed upon approved jacks in order to take up and correct any slight settlement which may occur after the placing has begun. M. FOUNDATION PITS AND FORMS All foundation pits and forms shall be inspected and approved by the Engineer prior to placing any part of the structure and the methods employed in performing the work and all equipment, tools and machinery used for handling materials and executing any part of the work shall be subject to the approval of the Engineer. All equipment, tools and machinery used must be maintained in a satisfactory working condition. Forms shall conform to the shape, lines and dimensions of the concrete as called for on the Plans. All plane form surfaces shall be constructed so that the finished concrete surfaces will be true planes, free from waves and irregularities. Lumber used in forms for exposed surfaces shall be straight, dressed to uniform width and thickness and shall be free from loose knots or other defects. Joints in forms shall be horizontal or, vertical. For unexposed surfaces, undressed lumber may be used. Lumber once used in forms 500-13 Section 500 1 Concrete shall have nails withdrawn and surfaces to be in contact with the concrete thoroughly cleaned before being used again. Forms shall be substantial and sufficiently tight to prevent leakage of mortar. They shall be properly braced or tied together in such a manner that they will maintain their original position and shape under the superimposed loads and the fluid pressure of the concrete. If adequate foundations for shores cannot be secured, trussed supports shall be provided. Where required by the Technical Specifications, concrete shall be poured , against waterproofed Douglas fir plywood, or waterproofed tempered hardpressed fiberboard, of a make and quality approved by the Engineer, and installed in strict conformity to the manufacturer's specifications. Forms used for backing up and otherwise supporting form lining shall have a flat surface but need not be tight. At the top of all walls or other surfaces which are to be finished to a true I line, the top of the form shall be brought to a true line and grade so that the surface may be finished by means of a float or template resting on the top edge of the form. Forms, on one side of the wall at least, shall not extend over horizontal construction joints. Flat steel bars or rods, unless otherwise authorized, shall be used for internal form ties. They shall be provided with lugs,nuts, cones or other approved devices, which will serve as spreaders or form spacers, and the ties shall have sufficient mechanical strength, stiffness and rigidity to hold the forms in proper position, spacing and alignment. The ties shall be of such design that the body of the tie will remain embedded in the concrete, with the ends of the ties not closer than 1/2 inch from the outer concrete surfaces. The ends of the embedded portion of the tie shall be provided with holes, corrugations, hooks, or other approved type of mortar clinch, and these ends shall be protected from the concrete by means of cone shaped shields of sufficient depth to provide adequate anchorage for the cement mortar plugs which shall be placed in the holes left by these shields. Wire form ties will be permitted only on light and unimportant work and with the approval of the Engineer. They shall not be used through surfaces where discoloration would be objectionable, wire ties, where used, must not be tightened by twisting, but shall be tightened by means of wedges placed outside the forms. No more initial stress is to be placed in the wire tie than is necessary to remove all slack. I Shores supporting successive stories shall below or so designated that the load will b Forms shall be set to line and grade and so provide and maintain true lines. Special bulging. e be placed directly over those transmitted directly to them. constructed and fastened as to care shall be used to prevent The forms for all walls should be such as to allow continuous pouring from the bottom to the top of the wall. Unless otherwise specified, suitable moulding or bevel strips shall be placed in the angles of forms to round or bevel the edges of the concrete. Bevel strips on the exposed corners of beams and girders shall be carried to within I I r 500-14 I Section 500 Concrete. I 1 I I 1 foot of the face of the.beam support. Bevel strips on the exposed corners of columns shall be carried to within 1 foot of their intersection with the edge of.a beam or girder of the same width as the column. If the column is from 2 to 6 inches wider than the largest beam or girder it supports, the bevel strips shall extend to within 2 inches of the bottom of the girder. If the column is 6 inches or more wider than the largest beam it supports, the bevel strips shall continue to within 1 foot of the bottom of the slab above the beam. Bevel strips onicolumns shall stop at a point 16 inches above the floor. The ends of all triangle bevel strips which do not extend the full length of the corners they occupy shall be cut off on an angle of 45°. Unless otherwise authorized by the Engineer, the inside of forms shall be coated with non -staining paraffin oil, or other approved material, applied before the reinforcement is placed, and all surplus oil removed from the surface of the forms by thorough wiping with soft absorbent cloths, Temporary openings shall be placed at the bottom of the column and wall forms, and at other points where, necessary to facilitate cleaning and inspection immediately before depositing concrete. Forms shall not be disturbed until the concrete has adequately hardened. Shoring shall not be removed until the member has acquired sufficient strength to support its weight and the load upon it. Members subject to additional loads during construction shall be adequately shored to support both the member and construction loads in such a manner as will protect the member from damage by the loads; this shoring shall not be removed until the member has acquired sufficient strength to support safely its weight and the load upon it. The following table gives the minimum time which shall elapse between the time of placing the concrete and the removal of forms at various average temperatures. Class of Work Walls in Mass Work Thin Walls 12 inches or less in thickness Above 600 500 to 600 40° to 50° Below 40° 1 day 2 days 5 days Not until tests have been made indicating con- crete is set. 2 days 4 days 7 days Columns - if girders 3 days 5 days 10 days are shored Bottom forms of slabs 4 days 8 days 14 days (5 feet or less span) Bottom forms of beams 14 days and girders (less than 14 inch. span) 20 days 28 days 500-15 Section 500 ■ Concrete If high early strength cement is used, these periods may be reduced as directed by the Engineer. When field operations are controlled by beam or cylinder tests, the removal of forms, supports and housing, and the discontinuance of heating and curing may be begun when the concrete is found to have a modulus of rupture of not less than 600 pounds per square inch or a compressive strength of 3,000 pounds per square inch, provided further that in no case shall supports be removed in less than seven days after pouring the concrete. The beams of cylinders shall be cured under conditions which are not more favorable than the most unfavorable conditions for the portions of the concrete which they represent. Form work in buildings should be so designed that the column forms may be removed without in any way disturbing the supports of the beams or girders, in order than any defect in the column may be detected and remedied before any load is placed on the column. Dimensions of all forms shall be carefully checked by the Contractor and the Engineer after they are erected and before the concrete is placed. The Contractor will be held responsible for the accuracy of all construction. N. CONSTRUCTION JOINTS Construction joints shall be made only where located on the Plans or shown in the placing schedule, unless otherwise approved by the Engineer. If not detailed on the Plans, •or in the case of emergency, construction joints shall be placed as directed by the Engineer. Shear keys or inclined reinforcement shall be used where necessary to transmit shear or bond the two sections together. Waterstops shall be placed as shown on the Plans and shall conform to requirements specified elsewhere in these Specifications. 0. HONEYCOMBING All concrete which, upon removal of the forms, is found to be porous or "honeycombed" shall be immediately cut out and removed entirely from the body of the concrete. The parts removed shall extend not less than 1 inch back of the reinforcement steel where such steel is present in the concrete face which is being repaired, removing sound concrete, if necessary, to obtain this depth. If reinforcement steel is not present, the parts removed shall extend into the concrete not less than 3 inches and the opening dovetailed in such a manner that the new concrete filling will be securely anchored. In replacing concrete so removed, forms shall be built with a spout or hopper outside the concrete surface, which shall be filled with fresh concrete to a point not less than 12 inches above the top of the hole caused by removing the porous concrete. The fresh concrete shall be properly bonded to the old concrete surfaces, as hereinbefore specified, and shall be well puddled. The hopper shall be removed after the concrete has hardened and within 24 hours after the 500-16 1 Section 500 Concrete concrete is placed, theexcess concrete carefully cut away; and the surface pointed and rubbed smooth. Concrete used in replacing porous concrete shall be protected from premature drying. Where the structural integrity of the structure may be in question due to honeycombing, the Engineer shall decide the appropriate action. P. FINISHING CONCRETE Face -forms shall be removed as soon as practicable in order to facilitate finishing the concrete surfaces. Care shall be taken to avoid roughening or injuring corners, and to keep all edges sharp. Immediately after the forms are removed, any fins or other projections shall be carefully removed, rough spots in the faces of the walls and any broken corners or edges shall be repaired and all bolt holes shall be plugged and entirely filled with mortar containing one part by volume of cement and two parts by volume of sand screened over a No. 8 screen. Pointing shall be brought smooth with the surface by means of a wooden float. A steel trowel 'I; shall not be used to finish the surface. Plastering will not be permitted. After the pointing has set sufficiently to permit it, all exposed surfaces on outside walls above finished grade and inside walls in tanks above the normal liquid level and inside walls of structures shall be thoroughly wetted and rubbed with a medium carborundum stone followed by a second rubbing with a fine carborundum stone to obtain an entire surface of a smooth texture and uniformity in color. A cement wash or plaster coat shall not be used. Particular attention is called to the fact that the tops of all walls shall be finished true to line and grade and shall be troweled smooth. Floors,, sidewalks, and other exposed wearing surfaces which require finishing shall be poured against carefully set screeds and troweled smooth with power operated trowels. Excess water shall be drained away or otherwise removed. The final finish with a steel trowel shall not be made until the cement has acquired its initial set. No more troweling shall be done than is necessary to obtain a smooth surface. At the option of the Engineer, the top surfaces of walks may be finished with a light broom or brush and an edging tool instead of a trowel. Sidewalks shall be laid out in blocks with an approved grooving tool as shown on the Plans or as directed by the Engineer. Care must be taken to avoid drawing an excess of cement to the surface of floors or walks. Dry cement or a dry mixture of cement and sand shall not be sprinkled directly on the surface. Floors shall be marked at the direction I. of the Engineer. Care shall be taken that all floor surfaces drain properly and that the grooving tool does not raise the surface of the floor and form pockets which do not drain: Floor requiring a mortar wearing coat will be so indicated on the Plans. Alternate or additional finishing specifications may be set out elsewhere on the Plans or in the Specifications. r500-17 Section 502 Concrete Materials • TECHNICAL SPECIFICATIONS APPURTENANT CONCRETE MATERIALS, JOINT FILLERS AND WATERSTOPS A.
