Very truly yours, McCLELLAND CONSULTING ENGINEERS, INC. GeJ Robert W. White, P.E. Vice President Attachment: Manhole Lining Specifications C:\W ORK1961961671AD12bn SPECIAL SPECIFICATIONS MANHOLE LINING SYSTEM A. GENERAL Under this section of the specifications, the contractor will provide a structural lining for the manhole in Job No. 2043. In constructing the structural lining, the contractor will have the option of using the Permaform system described below in section 'B' or a Glass - Fiber Reinforced Polyester Rehabilitation Manhole described below in section 'C'. With either option, the contractor will be required to excavate and remove the existing corbel and repair the existing incoming line as specified in the plans. B. PERMAFORM MANHOLE SYSTEM 1. General This method utilizes an internal forming system for placing a new and structurally independent 3" concrete wall within the existing structure. 2. Equipment Segmented, stackable steel forms having cylindrical and conical sections are employed. The assembled internal form shall have sufficient stiffness and strength to preclude shifting and/or collapse during concrete placement and to ensure safe man entry. The assembled form shall have an approximate cross section to provide the required minimum annular space. 3. Materials The concrete shall be Type I Portland cement mix with 5/8" minus coarse aggregate producing a mtmmum 4000 PSI compressive strength at full cure. A high-strength, quick setting cement grout shall be used as required for positioning and sealing the form at the manhole base and for maintaining active flows 4. Preparation The contractor shall employ adequate cleaning to remove loose material from the manhole, mindful that a chemical bond to the existing surface is not necessary. Existing steps that might interfere with the erection of the forms shall be removed. The contractor shall take all necessary precautions to prevent falling debns from damaging the trough and/or entering the sewer. Infiltration through existing manhole walls that would adversely affect the matenal used in the annular space shall be elinunated or reduced to an acceptable level SS -I 5. Installation Procedures a. The contractor shall place block-outs as needed to provide pipe inlets/outlets of the same diameter through the new concrete wall. All flows through the structure shall remain active unless otherwise indicated. c. The internal form shall be sized, erected and braced as necessary to assure that the new interior wall shall have a thickness of 3" extending from the manhole base to the bottom of the cone section, conforming generally to the interior dimensions of the existing structure and maintaining a 42" diameter or the maximum allowable by the existing dimension. The form shall be positioned, sealed and finished at the manhole base using cement grout to assure that concrete does not enter the sewer dung the operation. d. As the concrete is placed, it shall be consolidated to insure that it makes intimate contact with the plastic lined form and fill all pockets, seams and cracks: within the annular space. The contractor shall use adequate but not excessive vibration to prevent segregation of the concrete components. e. When the concrete has -sufficiently cured to preclude slump or damage, the form shall be moved. The connection pipes and drops shall be reinstated. A high strength, quick set grout shall be used to seal cracks and repair damage to the bench and invert. The manhole will be brought to final grade using a precast barrel section (if necessary), a concentric precast corbel, adjustment rings, and frame and lid constructed in accordance with specification section D2-14. 6. Quality Assurance The resultant concrete manhole wall shall be leak -free, smooth and free of honeycomb or areas of segregated aggregate. Any defects shall be promptly repaired and retested. Inspection and testing shall be performed by the contractor in the presence of the owner's representative. All work shall be performed by factory certified applicators. SS -2 C.

Soundness: In order to determine soundness, an air or water test is to be applied to the manhole test sample. While holding the pressure between 3 -5 psi, the entire manhole must be inspected for leaks. Any leakage through the laminate is cause for failure of the test. Refer to ASTM 3753, Sec. 8.6. Chemical Resistance: Per ASTM C 581; (see ASTM 3753, Section 8.7), Flexural strength, flexural modulus, and barcol hardness are plotted versus time on log -log coordinates. The line defined by these points is extrapolated to 100,000 hours. The minimum extrapolation retention allowed for any of these properties is 50%. Test samples used are actual pieces of manhole or samples manufactured in a manner consistent in every way with the manhole component construction. SS -6 6. Certification When requested by the purchaser on his order, a certification shall be made the basis of acceptance. This shall consist of a copy of the manufacturer's test report or a statement by the supplier, accompanied by a copy of the test results, that the manhole has been sampled, tested, and inspected in accordance with the provisions of ASTM 3753 and this specification, and meets all requirements. Each certification so furnished shall be signed by an authorized agent of the supplier or manufacturer. • 7. Shipping and Handling Do not drop or impact the fiberglass manhole. Lift manhole with two slings on spreader bar in horizontal position or by use of 4" x 4" timber inserted crosswise inside the manhole to the underside of the collar with a rope or chain attached to backhoe or other lifting device. Manhole may be rolled, however, insure that ground is smooth and free of rocks, debris, etc. Use of chains or cables in contact with manhole surface is prohibited. 8. Installation Methods a. The manhole installation should strictly follow the manufacturers recommended installation procedures. b. Excavate an area around the top of the existing manhole sufficiently wide and deep for removal of the existing corbel. Measure and cut required length of fiberglass rehab liner. The bottom of the liner must be cut to fit the existing manhole invert as closely as possible. Make cut-outs in liner wall to accommodate existing inlets, drops, and cleanouts. d. To lift manhole, insert 4" x 4" timber crosswise inside the manhole to the underside of the collar with a rope or chain attached to backhoe or other lifting device. Lower FRP manhole into manhole and mortar liner bottom in place. A good bottom seal should be obtained in order to prevent loss of grout from the annular space between the outside of the liner and the interior wall of the existing manhole. An additional height of grout should be placed above the initial bottom seal. Reinstate all pipe inserts. A high strength, quick set grout shall be used to seal cracks and repair damage to the bench and invert. SS -7 e.

Documents. The number of copies to be submitted will be determined by the Engineer after construction has started. b. Upon presentation of certified copies of purchase bills and freight bills, the Owner will permit inclusion in such monthly estimates payment for materials that will eventually be incorporated in.:the project, providing that such material is suitably stored on the site at the time of submission of the 1 I General Conditions City of Fayetteville Sanitary Sewer Improvements 68 LJ II Ii estimate for payment. At the time the next following monthly estimate is submitted, certified copies of receipted purchase and freight bills for the stored materials included in the monthly payment estimate submitted two months previously shall be submitted. 11 If the Contractor fails to submit proof of payment with the monthly payment estimate, those items of stored materials for which no proof of payment has 1A been submitted will be deleted from the current !� payment estimate. Such materials when so paid for by I' the Owner will become the property of the Owner and, in case of default on the part of the Contractor, the Owner may use or cause to be used by others these II materials in construction of the project. However, the Contractor shall be responsible for safe guarding such materials against loss or damage of any nature whatsoever, and in case of any loss or damage the �` Contractor shall replace such lost or damaged materials at no cost to the Owner.

(2) Five (5) percent after construction is 50 percent complete, provided that the Contractor ,is making adequate progress and there is no , specific cause for greater withholding. (3) When -the project is substantially complete (operational or beneficial use as determined by the Engineer) the retained amount will be reduced to two (2) percent of the value of work which is substantially complete, or two hundred (200) percent of the value of each item as determined by the Engineer to complete said item or items of work, whichever is greater. e.

Unit Price Items a. Unit price items listed in the Bid form and in the Agreement form may be of two types, "unit price construction items", and "unit price work items ordered by the Engineer during construction". For • all unit price items quantities as set forth are the best estimates which can be made during design, since actual quantities cannot be determined until construction is underway. b. The Contractor shall study carefully the Specifications to determine the extent and scope of the work included under lump sum items in the Contract. It may be that work under some unit price General Conditions City of Fayetteville Sanitary Sewer Improvements 70 I' items is in addition to similar work to be performed under lump sum items and paid for thereunder. IiC. Unit Price Construction Items Unit price construction items will be used to pay for 11 work not included under a lump sum item but required ll by the Contract. d. Unit Price Work Items Order by the Engineer During fl Construction These unit price items will be used to pay for II designated work, not shown on the Contract Drawings, when ordered by the Engineer in writing during construction. II4. Reporting and Invoicing Cost -of -Work '� All cost -of -work items shall be reported daily and signed by the Contractor and the Engineer, which daily reports shall thereafter be considered the true record of cost - 11 of- work done.

Engineer will, within fifteen (15) days after receipt of each payment request, either indicate in writing a recommendation of payment and present the request to Owner, or return the payment request to Contractor indicating in writing Engineer's reasons for refusing to recommend payment. In the latter case, Contractor may make the necessary corrections and resubmit the request. Thirty (30) days after presentation of the Application for Payment with Engineer's recommendation, the amount recommended will (subject to the provisions of paragraph O.7.f) become due and when due will be paid by Owner to Contractor. b. If the Owner fails to make payment thirty (30) days after review by the Engineer, in addition to other remedies available to the Contractor, there may be added to each such payment interest at an annual rate of twelve (12) percent commencing on the first day after said payment is due and continuing until the payment is received by the Contractor. c. Engineer's recommendation of any payment requested in a payment request will constitute a representation by Engineer to.Owner, based on Engineer's on -site observations of the work in progress as an experienced and qualified design professional and on Engineer's review of the payment request and the accompanying data and schedules that the work has progressed to the point indicated; that, to the best of the Engineer's knowledge, information and belief, the quality of the work is in accordance with the General Conditions City of Fayetteville Sanitary Sewer Improvements 72- I' Contract Documents (subject to an evaluation of the Work as a functioning whole prior to or upon 'i substantial completion, to the results of any subsequent tests called for in the Contract Documents to a final determination of quantities and I' classifications for Unit Price Work under paragraph J.8 and to any other qualifications stated in the recommendation); and that Contractor is entitled to II payment of the amount recommended. However, by recommending any such payment, Engineer will not thereby be deemed to have represented that exhaustive or continuous on -site observations have been made to check the quality or the quantity of the work, or I I that the means, methods, techniques, sequences, and procedures of construction have been reviewed or that any examination has been made to ascertain how or for rn what purpose Contractor has used the moneys paid or to be paid to Contractor on account of the Contract Price, or that title to any work, materials or equipment has passed to Owner free and clear of any Liens. 1I d. Engineer's recommendation of final payment will constitute an additional representation by Engineer to Owner that the conditions precedent to Contractor's being entitled to final payment as set forth in paragraph O.8.a have been fulfilled. e. Engineer may refuse to recommend the whole or any part of any payment if,. in Engineer's opinion, it I would be incorrect to make such representations to Owner. Engineer may also refuse to recommend any such payment, or, because of subsequently discovered evidence or the results of subsequent observations or tests, nullify any such payment previously recommended; to such extent as may be necessary to 11 Engineer's opinion to protect Owner from loss because: 'I (1) The Work is defective, or completed work has 1 been damaged requiring correction or 11 replacement. (2) The Contract Price has been reduced by Written Amendment or Change Order. General Conditions City of Fayetteville 73 Sanitary Sewer Improvements (3). Owner has been required to correct defective Work or complete the Work in accordance with paragraph N.6.b. (4) Engineer's actual knowledge of the occurrence of any of the events enumerated in paragraphs P.2.a.(1) through P.2.a.(9) inclusive. f. 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 performance 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. 8. Substantial Completion a. When Contractor. considers the entire work ready for its intended use and all final restoration and testing is complete, Contractor shall notify Owner and Engineer in writing the entire Work is Substantially Complete and request that Engineer issue a Statement of Substantial Completion. Within a reasonable time thereafter, Owner, Contractor and Engineer shall make an observation of the Work to determine the status of completion. If Engineer does not consider the work Substantially Complete, Engineer will notify Contractor in writing, giving his reasons therefore. If Engineer considers the work substantially.complete, Engineer will prepare and deliver to Owner a tentative Statement 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 corrected before final payment. This list shall be called a punch list. Owner shall have fourteen (14) days after receipt of the tentative certificate during which he may make written objection to Engineer as to any provisions of the certificate or attached list. If, after considering such objections., Engineer concludes that the Work is not Substantially Complete, Engineer will within General Conditions City of Fayetteville Sanitary Sewer Improvements 74 uJ I' fourteen days after submission of the tentative certificate to Owner notify Contractor in writing, stating his reasons therefore. If, after �� consideration of Owner's objections, Engineer 111 considers the Work Substantially Complete, Engineer �I will within said fourteen (14) days execute and deliver to Owner and Contractor a definitive Statement of Substantial Completion (with a revised I L tentative list of items to be completed or corrected) reflecting such changes from the tentative certificate as Engineer believes justified after fl consideration of any objections from Owner. At the time of delivery of the tentative Statement of Substantial Completion Engineer will deliver to 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 and insurance and warranties. Unless Owner �,and Contractor agree otherwise in writing and so inform Engineer prior to Engineer's issuing the definitive Statement of Substantial Completion, �I Engineer's aforesaid recommendation will be binding on Owner and Contractor until final payment. b. Owner shall have the right to exclude Contractor from the work after the date of Substantial Completion, but Owner shall allow Contractor reasonable access to 11 complete or correct items on the punch list. 9. Partial Utilization a. Use by Owner of any finished part of the Work, which �I has specifically been identified in the Contract Documents, or which Owner, Engineer and Contractor agree constitutes a separately functioning and useable part of the Work that can be used by Owner without significant interference with Contractor's performance of the remainder of the Work, may be 'I accomplished prior Substantial Completion of all the Work subject to the following: I (1) Owner at any time may request Contractor in writing to permit Owner to use any part of the work which Owner believes to be ready for its IIGeneral Conditions City of Fayetteville 11 75 Sanitary Sewer Improvements intended use and substantially complete. If Contractor agrees, Contractor will certify to Owner and Engineer that said part of the Work is substantially complete and request Engineer to issue a. Statement of Substantial Completion for that part of the Work. Contractor at any time may notify Owner and Engineer in writing that Contractor considers any such part of the Work ready for its intended use and substantially • complete and request Engineer to issue a Statement of Substantial Completion for that part of the Work. Within a reasonable time after either such request, Owner and Contractor shall observe that part of the Work to determine its status of completion. If Engineer does not consider that part of the Work to be substantially complete, Engineer will notify Owner and Contractor in writing giving the reasons therefore. If Engineer considers that part.of the Work to be substantially complete, the provisions of paragraph 0.8 will apply with respect to Statement of Substantial Completion of that part of the Work and the division of responsibility in respect thereof and access thereto. (2) Owner may at any time request Contractor 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 a reasonable time thereafter Owner, Contractor, and Engineer shall observe 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 writing 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 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, General Conditions City of Fayetteville Sanitary Sewer Improvements 76 Ll operation, safety, maintenance, utilities, insurance, warranties and guarantees for that I1 part of the Work which will become binding upon Owner and Contractor at the time when Owner takes over such operation (unless they shall 1 I have otherwise agreed in writing and so informed Engineer). During such operation and prior to ' I Substantial Completion of such part of the Work, Owner shall allow Contractor reasonable access to complete or correct items on said list and to II complete other related Work. (3) No occupancy or separate operation of part of the Work will be accomplished prior to compliance with the requirements of paragraph F.7 in respect of property insurance. 10. Final Observation Upon written notice from Contractor that Work or an agreed portion thereof is complete, Engineer will make a final observation with Owner and Contractor and will notify Contractor in writing of all particulars in which this observation reveals that the work is incomplete or defective. Contractor shall immediately take such measures as are necessary to remedy such deficiencies. 11, 11 I 11 1 11. Final Application For Payment After Contractor has completed all such corrections and delivered all maintenance and operating instructions, schedules, guarantees, Bonds, certificates of inspection, marked -up record documents as provided in paragraph G.11 and other documents - all as required by the Contract Documents, and after Engineer has indicated that the Work is acceptable, subject to the provisions of paragraph O.16 Contractor may make application for final payment request following the procedure for progress payment requests. The final payment requests 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.

If any Subcontractor, Supplier fails to furnish a release or receipt in full, Contractor may furnish a Bond or other collateral satisfactory to Owner to indemnify Owner against any Lien. 12. Final Payment and Acceptance a. If, on the basis of Engineer's observation of the Work during construction and final observation, and Engineer's review of the final payment request and accompanying documentation - all as required by the Contract Documents, Engineer has been shown that the work has been completed and Contractor's other obligations under the Contract Documents have been fulfilled, Engineer will, within ten (10) days after receipt of final payment request, indicate in writing Engineer's recommendation of payment and present the request 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 O.14. Otherwise, Engineer will return the payment request to Contractor, indicating in writing the reasons for refusing to recommend final payment, in which case Contractor shall make the necessary corrections and resubmit the payment request.

Such payment shall be made under the terms and conditions governing final payment, except that it shall not constitute a waiver of claims. 13. Contractor's Continuing Obligation Contractor's obligation to perform and complete 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 certificate of substantial completion, nor any payment of 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 the issuance of a notice of acceptability by Engineer pursuant to paragraph O.12, nor any correction of defective work by Owner shall constitute an acceptance of Work not in accordance with the Contract Documents or a release of Contractor's obligation to perform the Work in accordance with the Contract Documents (except as provided in paragraph O.14). 14. Waiver of Claims The making and acceptance of final payment shall constitute: a. A waiver of all claims by Owner against Contractor, except claims arising from unsettled Liens, from defective Work appearing after final observation pursuant to paragraph O.10 or from failure to comply with the Contract Documents or the terms of any special guarantees specified therein; however, it will not constitute a waiver by Owner of any rights in respect of Contractor's continuing obligations General Conditions City of Fayetteville 79 Sanitary Sewer Improvements LQ under the Contract Documents. b. A waiver of all claims by Contractor against Owner other than those previously made in writing and still unsettled. 1. Owner May Suspend Work a: Owner may, at any time and without cause, suspend the work or any portion thereof for a period of not more than ninety (90) days by notice in writing to Contractor and Engineer which shall fix the date on which work shall be resumed.

Any such preemption is to be limited to the extent possible. Section 18 of the Occupational Safety and Health Ad of 1970 expresses Congress dear intent to preen pt state laws relating to issues on which Federal OSHA has promulgated occupational safety and health standards. Under the OSH Act, a elate can avoid preemption only if it submits, and obtains Federal approval of, a plan (or the development of such standards and their enforcement. Occupational safety end health standards developed by such Plan -States must, among other things, be at least as effective in providing safe and healthful employment and places of employment as Federal Standards. Where such standards are applicable to products distributed or used in Interstate commerce. they may Dot unduly burden commerce and must be justified by compelling local conditions (See Section I B(cX2) of the OSH Act). This regulation is drafted so that employees in every state would be protected by general, performance - oriented standards. To the extent that them are state or regional peculiarities caused by the terrain, the climate or other factors. states would be able, under the OSH Ad. to develop their own state standards to deal with any speial problems.

Scope This section describes manhole testing to effectively confirm the watertight integrity of new manholes. Description a. Infiltration may be observed in manhole defects at manhole walls, pipe seals or bench/trough areas. Infiltration related repairs are intended to eliminate leakage of groundwater into manholes. b. Inflow may be observed in manhole defects at manhole frames, covers, frame seals, grade adjustments, grade adjustment seals, corbels, or walls. Inflow related repairs are intended to eliminate sources of surface water entry that become active during rainfall events. 3. Testing, Observations and Guarantee Period a. The testing required shall be performed by the Contractor at locations designated by the Engineer and documented to the satisfaction of the Engineer. b. Any new manholes that are observed to be leaking by the Engineer shall be repaired by the Contractor and retested. B. Materials Not specified. C. Execution 1. Infiltration Testing a. All new manholes shall be vacuum tested by the Contractor in the presence of the Engineer for sources of infiltration. Testing will be made during high groundwater conditions, wherever I D1-7(1) City of Fayetteville Sewer System Improvements I possible. All testing shall be performed in the presence of the Engineer. b. Manholes shall be tested after installation with all connections (existing and/or proposed) in place. Drop -connections and gas sealing connections shall be installed prior to testing. The lines entering the manhole shall be temporally plugged with the .plugs braced to prevent them from being drawn into the manhole. The plugs shall be installed in the lines beyond drop -connections, gas sealing connections, etc. The test head shall be placed inside the frame at the top of the manhole and inflated in accordance with the manufacturer's recommendations. A vacuum of 10 inches of mercury shall be drawn, and the vacuum pump will be turned off. With the valve closed, the level of vacuum shall be read after the required test time. If the drop in the level is less than 1 -inch of mercury (final' vacuum greater than 9 inches of mercury), the manhole will have passed the vacuum test. After a successful test, the temporary plugs will be removed. The required test time is determined from Table I.

Manhole vacuum levels observed to drop greater than 1 -inch of mercury (Final vacuum less than 9 inches of mercury) will have failed the test and will require additional rehabilitation. The Contractor S I U 1I I 1I ri �I City of Fayetteville D1-7(2) 1 Sewer System Improvements I Ishall make the necessary repairs at no additional compensation. The manhole shall then be retested as described above until a successful test is made. 2. Inflow Testing a. All new manholes and manholes where new pipe connections are made shall be dyed water tested. Manholes shall be dye water tested in the presence of the Engineer. The dye test shall consist of applying a concentrated dye solution around the manhole frame. Dyed water shall be applied for at least ten minutes. b. Manholes observed to be actively leaking will have failed the test and will not be acceptable. Manholes failing the test will be repaired by the Contractor at no additional compensation. The Contractor shall be responsible for only those work items 'completed by the Contractor. The manhole shall then be retested as described above until a successful test is made. D. Measurement and Payment No contract unit prices are established for manhole testing. However, specific sections of the Contract Documents indicate that certain percentages of various contract prices will not be eligible for payment unless testing has been performed.

Scope This Section governs the furnishing of all labor, equipment, tools and materials, for the performance of acceptance tests. 2. Description The Contractor shall furnish all materials, water, equipment, labor and reports for the required tests. All pipelines, including repaired building service lines shall undergo and pass tests to determine the soundness and workmanship regarding alignment, grade, infiltration, exfiltration and/or pressure. Pipelines which do not conform to the project requirements shall be repaired and/or replaced along with all appurtenant work necessary to complete the entire work according to the Contract Documents at no additional cost to the Owner and shall be retested until the pipeline is of a condition meeting the project requirements. Results of each test shall be recorded by the Contractor in a neat, professional manner and three (3) copies shall be submitted to the Engineer. Test shall be performed after backfill and compaction operation has been completed. Testing for acceptability of the sanitary sewers shall be conducted by: a. Internal Inspection b. Infiltration Test c. Low Pressure Air Test (Exfiltration) d. Deflection Test At a minimum either the low pressure air test or the 1 infiltration test, in addition to internal inspection, shall be required for acceptance of the sanitary sewers. Deflection testing shall be required for polyvinylchloride pipe. Where the new sewer constructed replaces an existing sewer with active service connections, only internal inspection during high groundwater conditions shall be required. The Engineer n 9 D1-9(1) City of Fayetteville Sewer System Improvements may require individual joints to be pressure tested. If all joint test results conform to the specified leakage then the cost of the test will be paid for by the Owner. If any joint test results do not conform to specified leakage, then the cost of the test and repairs required to properly install the pipe will be paid for by the Contractor and at no additional cost to the Owner. Replacement sewers and service laterals that parallel or cross storm drains or ditch sections shall also be tested in accordance with Section Dl -8.C.1 to determine that inflow has been eliminated from the sewer system.

(a) Scope and application- This sub• part applies to all open excavations made in the earth's surface. Excava- tions are defined to include trenches. (b) Definitions applicable to this subpart Accepted engineering practices means those requirements which are compatible with standards of practice required by a registered professional engineer. - AIuminum Hydraulic Shoring means a pre-engineered shoring system com- prised of aluminum hydraulic cylin- ders (crossbraces) used in conjunction with vertical rails (uprights) or hori- zontal rails(walers), Such system is designed,. specifically to support the sidewalls of an excavation and prevent cave-ins. Bell-bottom pier hole means a type of shaft or footing excavation, the bottom of which is made larger than the cross section above to form a belled shape. • ;� II 218 I [] I I I I I I I I I Li I I I I Occupational Safety and H.ollh Admin., Labor 11,•nrhtnu Ilirnchmf S>stvin) mt'am a method of protecting employees from cave-ins by excavating the sides of an excavation to form one or a series of horizontal levels or steps, usually with vertical or near -vertical surfaces between levels. Cave-in means the separation of a mass of soil or rock material from the side of an excavation, or the loss of soil from under a trench shield or sup- port system, and its sudden movement Into the excavation, either by falling or sliding, in sufficient quantity so that it could entrap, bury, or other- wise Injure and immobilize a person. Competent person means one who is capable of identifying existing and predictable hazards in the surround- ings, or working conditions which are unsanitary, hazardous, or dangerous to employees, and who has authoriza- tion to take prompt corrective meas- ures to eliminate them. Cross braces mean the horizontal members of a shoring system installed perpendicular to the sides of the exca- vation, the ends of which bear.against either uprights or wales. Excavation means any manmade cut, cavity, trench, or depression in an earth surface, formed by earth remov- al. Faces or sides means the vertical or inclined earth surfaces formed as a result of excavation work. Failure means the breakage, dis- placement, or permanent deformation of a structural member or connection so as to reduce its structural integrity and its supportive capabilities. Hazardous atmosphere means an at- mosphere which by reason of being ex- plosive, flammable, poisonous, corro- sive, oxidizing, irritating, oxygen defi- cient, toxic, or otherwise harmful, may cause death. illness, or injury. Kickout means the accidental re- lease or failure of a cross brace. Protective system means a method of protecting employees from cave-ins, from material that could fall or roll from an excavation face or into an ex- cavation, or from the collapse of adja- cent structures. Protective systems in. elude support systems, sloping and benching systems, shield systems, and other systems that provide the neces- sary protection. § 1926.650 Rump inr:uts Jul uu ii:.rd ttalf.ing or working surface that Is used to gain access to one point from another, and Is constructed from earth or from structural materials such as steel or wood. Registered Professional Engineer means a person who is registered as a professional engineer in the state where the work is to be performed. However, a professional engineer. reg- istered in any state Is deemed to be a "registered professional engineer" within the meaning of this standard when approving designs for "manufac- tured protective systems" or 'tabulat- ed data" to be used in interstate com- merce. Sheeting means the members of a shoring system that retain the earth in position and in turn are supported by other members of the shoring system. Shield (Shield system) means a structure that is able to withstand the forces imposed on it by a cave-in and thereby protect employees within the structure. Shields can be permanent structures or can be designed to be portable and moved along as work pro- gresses. Additionally, shields can be either premanufactured or job -built in accordance with 11926.652 (c)(3) or (c)(4). Shields used in trenches are usually referred to as "trench boxes" or "trench shields." Shoring (Shoring system) means a structure such as a metal hydraulic, mechanical or timber shoring system that supports the sides of an excava- tion and which is designed to prevent cave-ins. Sides. See "Faces." Sloping (Sloping system) means a method of protecting employees from cave-ins by excavating to form sides of an excavation that are inclined away from the excavation so as to prevent cave-ins. The angle of incline required to prevent a cave-in varies with differ- ences in such factors as the soil type, environmental conditions of exposure, and application of surcharge loads. Stable rock means natural solid min- eral material that can be excavated with vertical sides and will remain intact while exposed. Unstable rock is considered to be stable when the rock material on the side or sides of the ex - 219 I § 1926.651 cacnliun is secured ngninst cnving.In or movement by rock bolts or by another protective system that has been de- signed by a registered professional en- gineer. Structural ramp means a ramp built of steel or wood, usually used for vehi- cle access. Ramps made of soil or rock are not considered structural ramps. Support system means a structure such as underpinning, bracing,. or shoring, which provides support to an adjacent structure, underground in- stallation, or the sides of an excava- tion. Tabulated data means tables and charts approved by a registered profes- sional engineer and used to design and construct a protective system. Trench (Trench excavation) means a narrow excavation (in relation to its length) made below the surface of the ground. In general, the depth is great- er than the width; but the width of a trench (measured at the bottom) is not greater than 15 feet (4.6 m). If forms or other structures are installed or constructed in an excavation so as to reduce the dimension measured from the forms or structure to the side of the excavation to 15 feet (4.6 m) or less (measured at the bottom of the excavation), the excavation is also con- sidered to be a trench. Trench box. See "Shield." Trench shield. See "Shield." Uprights means the vertical mem- bers of a trench shoring system placed in contact with the earth and usually positioned so that individual members do not contact each other. Uprights placed so that individual members are closely spaced, in contact with or interconnected to each other, are often called "sheeting." Wales means horizontal members of a shoring system placed parallel to the excavation face whose sides bear against the vertical members of the shoring system or earth. § 1926.651 General requirements. (a) Surface encumbrances. All sur- face encumbrances that are located so as to create a hazard to employees shall be removed or supported, as nec- essary, to safeguard employees.

(iv) When controls are used that are intended to reduce the level of atmos- pheric contaminants to acceptable levels, testing shall be conducted as often as necessary to ensure that the atmosphere remains safe. (2) Emergency rescue equipment (i) Emergency rescue equipment, such as breathing apparatus, a safety harness and line, or a basket stretcher, shall be readily available where hazardous at- mospheric conditions exist or may rea- sonably be expected to develop during work in an excavation. This equipment shall be attended when In use. (ii) Employees entering bell-bottom pier holes, or other similar deep and confined footing excavaticns, shall wear a harness with a life -line securely attached to it. The lifeline shall be separate. from any line used to handle materials, and shall be individually at- tended at all times while the employee wearing the lifeline is in the excava- tion. (h) Protection from hazards associ- ated with water accumulation. (1) Em- ployees shall not work in excavations in which there is accumulated water, or in excavations in which water is ac- cumulatin€, unless adequate precau- tions have been taken to protect em- ployees against the hazards posed by water accumulation. The precautions necessary to protect employees ade- quately vary with each situation, but 221 I § 1926.651 could include special support or shield systems to protect from cave-ins. water removal to control the level of accumulating water, or use of a safety harness and lifeline. (2) If water Is controlled or prevent- ed from accumulating by the use of water removal equipment, the water removal equipment and operations shall be monitored by a competent person to ensure proper operation. (3) if excavation work interrupts the natural drainage of surface water (such as streams), diversion ditches, dikes, or other suitable means shall be used to prevent surface water from en- tering the excavation and to provide adequate drainage of the area adja- cent to the excavation. Excavations subject to runoff from heavy rains will require an inspection by a competent person and compliance with para- graphs (h)(1) and (h)(2) of this sec- tion. (I) Stability of adjacent structures. (1) Where the stability of adjoining buildings, walls, or other structures is endangered by excavation operations, support systems such as shoring, brac- ing, or underpinning shall be provided to ensure the stability of such struc- tures for the protection of employees. (2) Excavation below the level of the base or footing of any foundation or retaining wall that could be reason- ably expected to pose a hazard to em- ployees shall not be permitted except when: (i) A support system, such as under- pinning, is provided to ensure the safety of employees and the stability of the structure; or (ii) The excavation is in stable rock: or (iii) A registered professional engi- neer has approved the determination that the structure is sufficently re- moved from the excavation so as to be unaffected by the excavation activity: or (iv) A registered professional engi- neer has approved the determination that such excavation work will not pose a hazard to employees. (3) Sidewalks, pavements, and appur- tenant structure shall not be under- mined unless a support system or an- other method of protection Is provided 29 CFR Ch. XVII (7-1-92 Edition) to protect employees from the pussible collapse of such structures. (J) Protection of employees from loose rock or soil. (1) Adequate protec- tion shall be provided to protect em- ployees from loose rock or soil that could pose a hazard by falling or roll- ing from an excavation face. Such pro- tection shall consist of scaling to remove loose material: installation of protective barricades at intervals as necessary on the face to stop and con- tain falling material: or other means that provide equivalent protection. (2) Employees shall be protected from excavated or other materials or equipment that could pose a hazard by falling or rolling into excavations. Pro- tection shall be provided by placing and keeping such materials or equip- ment at least 2 feet (.61 m) from the edge of excavations, or by the use of retaining devices that are sufficient to prevent materials or equipment from falling or rolling into excavations, or by a combination of both if necessary. (k) lnsprctions. (1) Daily inspections of excavations, the adjacent areas, and protective systems shall be made by a competent person for evidence of a sit- uation that could result in possible cave-ins, indications of failure of pro- tective systems, hazardous atmos- pheres, or other hazardous conditions. An inspection shall be conducted by the competent person prior to the start of work and as needed through- out the shift. Inspections shall also be made after every rainstorm or other hazard increasing occurrence. These inspections are only required when employee exposure can be reasonably anticipated. (2) Where the competent person finds evidence of a situation that could result in a possible cave-in, indications of failure of protective systems, haz- ardous atmospheres, or other hazard- ous conditions, exposed employees shall be removed from the hazardous area until the necessary precautions have been taken to ensure their safety.

APPENDIX A TO SUBPART P —SOIL CLASSIFICATION (a) Scope and application —(1) Scope. This appendix describes a method of classifying soil and rock deposits based on site and envi- ronmental conditions, and on the structure and composition of the earth deposits. The appendix contains definitions. sets forth re- quirements. and describes acceptable visual and manual tests for use in classifying soils. (2) Application. This appendix applies when a sloping or benching system is de- signed in accordance with the requirements set forth in 11926.652(b)(2) as a method of protection for employees from cave-ins. This appendix also applies when timber shoring for excavations is designed as a method of protection from cave-ins in ac- cordance with appendix C to subpart P of part 1926, and when aluminum hydraulic shoring is designed In accordance with ap- pendix D. This Appendix also applies if other protective systems are designed and selected for use from data prepared in ac- cordance with the requirements set forth In I1926.652(c), and the use of the data is 225 I Svbpt. P, App. A predicated on the use of the soil clausifica tion system set forth in this appendix. (b) Dciinittons. The definitions and exam• pies given below are based on. in whole or in part, the following: American Society for Testing Materials (ASTM) Standards D653- 85 and D2488; The Unified Soils Classifica- tion System. The U.S. Department of Agri- culture (USDA) Textural Classification Scheme: and The National Bureau of Stand• ards Report BSS -121. Ccntrnted soil means a soil in which the particles are held together by a chemical agent, such as calcium carbonate, such that a hand size sample cannot be crushed into powder or individual soil particles by finger pressure. Cohesive soil means clay (fine grained soil), or soil with a high clay content, which has cohesive strength. Cohesive soil does not crumble, can be excavated with vertical sideslopes. and is plastic when moist. Cohe- sive soil is hard to break up when dry, and exhibits significant cohesion when sub• merged. Cohesive soils Include clayey silt, sandy clay, silty clay, clay and organic clay. Dry soil means soil that does not exhibit visible signs of moisture content. Fissured means a soil material that has a tendency to break along definite- planes of fracture with little resistance, or a material that exhibits open cracks, such as tension cracks. In an exposed surface. Granular soil means gravel, sand, or silt. (coarse grained soil) with little or no clay content. Granular soil has no cohesive strength. Some moist granular soils exhibit apparent cohesion. Granular soil cannot be molded when moist and crumbles easily when dry. Layered system means two or more dis• tlnctly different soil or rock types arranged in layers. Micaceous seams or weakened planes Ir rock or shale are considered lay- ered. Moist soil means a condition in which a soil looks and feels damp. Moist cohesive soil can easily be shaped into a ball and rolled into small diameter threads before crumbling. Moist granular soil that contains some cohesive material will exhibit signs of cohesion between particles. Plastic means a property of a soil which allows the soil to be deformed or molded without cracking, or appreciable volume change. Scturatcd soil means a soil In which the voids are filled with water. Saturation does not require flow. Saturation, or near satura- tion. is necessary for the proper use of In- struments such as a pocket penetrometer or sheer vane. Soil classification system means, for the purpose of this subpart, a method of catego- rizing soil and rock deposits In a hierarchy of Stable Rock, Type A. Type B, and Type C, in decreasing order of stability. The ate• 29 CFR Ch. XVII (7-1-92 Edition) gorirs are drtermined based On an Rnalysls of the properties and performance char -at• leristics of the deposits and the envlron• mental conditions of exposure. Stable rock means natural solid mineral matter that can be excavated with vertical sides and remain intact while exposed. S:.brnerged soil means soil which is under- water or is free seeping. T,pe A means cohesive soils with an un• confined compressive strength of 1.5 ton per square foot (tsf) (144 kPa) or greater. Exam- ples of cohesive soils are: clay, silty clay, sandy clay, clay loam and, in some cases, silty clay loam and sandy clay loam. Ce mented soils such as caliche and hardpan are also considered Type A. However, no soil is Type A If: 0 The soil is fissured: or iii) The soil is subject to vibration from heavy traffic, pile driving, or similar effects: or (iii) The soil has been previously dis- turbed; or (iv) The soil is part of a sloped, layered system where the layers dip into the excava- tion on a slope of four horizontal to one ver- tical (4H:1V) or greater; or (v) The material is subject to other factors that would require it to be classified as a less stable material. Type B means: (I) Cohesive soil with an unconfined com- pressive strength greater than 0.5 tsf (48 kPa) but less than 1.5 tsf (144 kPa); or (ii) Granular cohesionless soils including: angular gravel (similar to crushed rock), silt, silt loam, sandy loam and. In some cases, silty clay loam and sandy clay.loam. (Iii) Previously disturbed soils except those which would otherwise be classed as Type C soil. (iv) Soil that meets the unconfined com- pressive strength or cementation require- ments for Type A. but is fissured or subject to vibration: or (v•) Dry rock that is not stable: or (vi) Material that is part of a sloped, lay- ered system where the layers dip into the excavation on a slope less steep than four horizontal to one vertical (4H:1V), but only If the material would otherwise be classified as Type B. Type Cmeans: (I) Cohesive soil with an unconfined com• pressive strength of 0.5 tsf (48 kPa) or less; or (ii) Granular soils Including gravel, sand, and loamy sand: or (Iii) Submerged soil or soil from which water is freely seeping: or (iv) Submerged rock that is not stable, or (v) Material in a sloped, layered system where the layers dip into the.excavatlon or a slope of four horizontal to one vertical (4H:1V) or steeper. i I I I .I I I I I I I I I i 1] I I I I I i I I Occupational Safety and Health Admin., labor I'Il,lli('t 11,,i t•„ l l;)I I f').t:I ( s!It'n vt)1 nll ails the load per unll MCA at which a soil will (all in compression. It can be determined by laboratory testing, or estimated in the field using a pocket penetronictrr. by thumb pen- etration testa. and other methods. Wet soil means soil that contains slgnifl- eantly more moisture than moist soil. but in such a range of values that cohesive malerl- al will slump or begin to flow when vibrated. Granular material that would exhibit cohe- sive properties when moist will lose those cohesive properties when wet. (e) Requirements —(1) Classification of soil and rock deposits. Each soil and rock deposit shall be classified by a competent person as St:,ble Rock. Type A. Type B. or Type C in accordance with the definitions set forth In paragraph (b) of this appendix. (2) Basis of cinsstficction. The claoifica- tion of the deposits shall be made based on the results of at least one visual and at least one manual analysis. Such analyses shall be conducted by a competent person using tests described in paragraph (d) below, or in other recognized methods of soil classifica- tion and testing such as those adopted by the America Society for Testing Materials. or the U.S. Department of Agriculture tex- tural classification system. (3) Visual and manual analyses. The visual and manual analyses, such as those noted as being acceptable in paragraph (d) of this appendix, shall be designed and, con- ducted 'toprovide sufficient quantitative and qualitative information as may be nec- essary to identify properly the properties, factors, and conditions affecting the classif I - cation of the deposits. (4) Layered systems. In a layered system. the system shall be classified in accordance with its weakest layer. However, each layer may be classified individually where a more stable layer lies under a less stable layer. (5) Reclassification. If, after classifying a deposit. the properties, factors, or condi- tions affecting Its classification change in any way, the changes shall be evaluated by a competent person. The deposit shall be re- classified as necessary to reflect the changed circumstances. (d) Acceptable visual and manual tests. — (1) Visual tests. Visual analysis is conducted to determine qualitative information regard- ing the excavation site in general. the soil adjacent to the excavation, the soil forming the sides of the open excavation, and the soil taken as samples from excavated mate- rial. to Observe samples of soil that are exca- vated and soil in the sides of the excavation. Estimate the range of particle sizes and the relative amounts of the particle sizes. Soil that is primarily composed of fine-grained material Is cohesive material. Soil composed primarily of coarse -grained sand or gravel Is granular material. Subpt. P, App. A 111' t'L •rl\t' ,.'ii a.' 11 Is l'x, ;kt a I,'tt.

(lit) Observe the side of the opened exca• vation and the surface area adjacent to the excavation. Crack like openings such as ten- sion cracks could indicate fissured material. If chunks of soil span off a vertical side, the soil could be (l.sured. Small spalls are evi. dunce of moving ground and are indications of potentially hazardous situations. (Iv) Observe the area adjacent to the exca- vation and the excavation Itself for evidence of existing utility and other underground structures.' and to identify previously dis- turbed soil. (v) Observe the opened side of the excava- tion to identify layered systems. Examine layered systems to identify if the layers slope toward the excavation. Estimate the degree of slope of the layers. (vi) Observe the area adjacent to the exca- vation and the sides of the opened excava- tion for evidence of surface water, water seeping from the sides of the excavation, or the location of the level of the water table. (vii) Observe the area adjacent to the ex- cavation and the area within the excavation for sources of vibration that may affect the stabUity of the excavation face. (2) Manual tests. Manual analysis of soil samples is conducted to determine quantita- tive as well as qualitative properties of soil and to provide more information in order to classify soil properly. (I) PIasticity. Mold a moist or wet sample of soil Into a ball and attempt to roll it into threads as thin as Ya-inch in diameter. Cohe- sive material can be successfully rolled into threads without crumbling. For example. If at least a two inch (50 mm) length of Y. -inch thread can be held on one end without tear- ing, the soil Is cohesive. (it) Dry stren➢th If the soil is dry and crumbles on its own or with moderate pres- sure into Individual grains or fine powder. It is granular (any combination of gravel, sand, or silt). lithe soil Is dry and falls into clumps which break up into smaller clumps. but the smaller clumps can only be broken up with difficulty, it may be clay in any combination with gravel, sand or silt. If the dry soil breaks into clumps which do not break up into small clumps and which can only be broken with difficulty, and there is no visual indication the soil is fissured, the soil may be considered unfissured. (iii) Thumb penetration. The thumb pene- tration test can be used to estimate the un• confined compressive strength of cohesive soils. (This test is based on the thumb pene- tration test described in American Society for Testing and Materials (ASTM) Standard designation D2488 —"Standard Recommend- ed Practice for Description of Soils (Visual - 227 Subpt. P, App. S htRnual Procedure).'•) Type A snits with an unconfined compressive strength of 1.5 tsf can be readily indented by the thumb: how- ever, they can be penetrated by the thumb only with very great effort. Type C soils with an unconfined compressive strength of 0.5 tsf can be easily penetrated several Inches by the thumb, and can be molded by light finger pressure. This test should be conducted on an undisturbed soil sample. such as a large clump of spoil. as soon as practicable after excavation to keep to a ml minurn the effects of exposure to drying In• flucnces. If the excavation is later exposed to wetting influences (rain. flooding), the classification of the soil must be changed ac- cordingly. (Iv) Other strength tests. Estimates of un- confined compressive strength of soils can also be obtained by use of a pocket pene- trometer or by using a hand -operated shear - vane. (v) DR'ing test The basic purpose of the drying test is to differentiate between cohe- sive material with fissures, unfissured cohe- sive material, and granular material. The procedure for the drying test Involves drying a sample of soil that is approximate- ly one inch thick (2.54 cm) and six Inches (15.24 cm) In diameter until it is thoroughly dry: (A) If the sample develops cracks as it dries, significant fissures are Indicated. (B) Samples that dry without cracking are to be broken by hand. If considerable force is necessary to break a sample, the soil has significant cohesive material content. The soil can be classified as a unfissured cohe- sive material and the unconfined compres- sive strength should be determined. (C) If a sample breaks easily by hand, it is either a fissured cohesive material or a granular material. To distinguish between the two, pulverL-.e the dried clumps of the sample by hand or by stepping on them. If the clumps do not pulverize easily, the ma- terial is cohesive with fissures. If they pul- verize easily into very small fragments, the material is granular. APPENDIX B TO SUBPART P -SLOPING AND BENCHING (a) Scope and application. This appendix contains specifications for sloping and benching when used as methods of protect- ing employees working In excavations from cave-ins. The requirements of this appendix apply when the design of sloping and bench - 29 CFR Ch. XVII (7-1-92 Edition) Ing prutecticc s) stems is to be perfknmed in accordance with the requirements set forth In 1 1926.652(b)t2). .(b) Deftnitfons. Actual slope means the slope to which an excavation face is excavated. Distress means that the soil Is In a condi- tion where a cave•in is imminent or is likely to occur. Distress is evidenced by such phe• nomena as the development of fissures in the face of or adjacent to an open excaca• Lion: the subsidence of the edge of an exca- vation; the slumping of material from the face or the bulging or heaving of material from the bottom of an excavation: the spall- Ing of material from the face of an excava- tion: and ravelling. I.e., small amounts of material such as pebbles or little clumps of material suddenly separating from the face of an excavation and trickling or rolling down into the excavation. Maximum allowable slope means the steepest incline of an excavation face that is acceptable;for the most favorable site condi- tions as protection against cave-ins, and Is expressed as the ratio of horizontal distance to vertical rise (H:V). Short term exposure means a period of time less than or equal to 24 hours that an excavation is open. (c) Requirements —(1) Soil classification - Soil and rock deposits shall classified in accordance with appendix A to subpart P of part 1926. (2) Maximum allowable slope. The maxi- mum allowable slope for a soil or rock de- posit shall be determined from Table B-1 of this appendix. (3) Actual slope. (I) The actual slope shall not be steeper than the maximum allowable slope. (ii) The actual slope shall be less steep than the maximum allowable slope, when there are signs of distress. If that situation occurs, the slope shall be cut back to an actual slope which is at least ½ horizontal to one vertical (%H:IV) less steep than the maximum allowable slope. (iii) When surcharge loads from stored material or equipment, operating equip- ment, or traffic are present. a competent person shall determine the degree to which • the actual slope must be reduced below the maximum allowable slope, and shall assure that such reduction is achieved. Surcharge loads from adjacent structures shall be eval- uated in accordance with 4.1926.651(1). (4) Configurations.

Stable rock Is exempt from shoring require- nlents and therefore. no data are presented for this condition. 12) Information concerning the basis of the tabular data and the limitations of the dhta Is presented In paragraph (d) of this appendix. and on the tables themselves. (3) Information explaining the use of the tabular data is preso need In paragraph (e) of thu' appendix. (4) information illustrating the use of the tabular data is presented in paragraph (f) of this appendix. (5) Miscellaneous notation regarding Tables C-1.1 through C-1.3 and Tables C- 2.1 through C -2.g are presented in para- graph (g) of this Appendix. (d) Basis and limitations of the data. —(1) Dimensions of timber members. (1) The sizes of the timber members listed in Tables C- 1.1 through C-1.3 are taken from the Na- tional Bureau of Standards (NBS) report, "Recommended Technical Provisions for Construction Practice in Shoring and Slop- ing of Trenches and Excavations." In addi- tion. where NBS did not recommend specific sizes of members, member sizes are based on an analysis of the sizes required for use by existing codes and on empirical practice. (ii) The required dimensions of the mem- bers listed in Tables C-1.1 through C-1.3 refer to actual dimensions and not nominal dimensions of the timber. Employers want- ing to use nominal size shoring are directed to Tables C-2.1 through C-2.3, or have this choice under 11926.652(c)(3), and are re• (erred to The Corps of Engineers. The Bureau of Reclamation or data from other acceptable sources. (2) Limitation of application. (I) It is not intended that the timber shoring specifica- tion apply to every situation that may be experienced in the field. These data were developed to apply to the situations that are most commonly experienced in current trenching practice. Shoring systems for use in situations that are not covered by the data in this appendix must be designed as specified in 1 1926.652(c). (ii) When any of the following conditions are present, the members specified In the tables are not considered adequate. Either an alternate timber shoring system must be designed or another type of protective system designed In accordance with 41926.652. Subpt. P. App. C tA) Whvn loads intpused by structure. ur by stored material adJacent to the trench weigh In excess of the load Imposed by a two foot soil surcharge. The term "adJa. cent" as used here means the area within a horizontal distance from the edge of the trench equal to the depth of the trench. (B) When vvrtral loads Imposed on cross braces exceed a 240•pound gravity load dis- tribuled on a one•foot section of the center of the crus'brace. (C) When surcharge loads are present from equipment weighing in excess of 20.000 pounds. (D) When only the lower portion of a trench Is shored and the remaining portion of the trench is sloped or benched unless: The sloped portion Is sloped at an angle less steep than three horizontal to one vertical: or the members are selected from the tables for use at a depth which is determined from the top of the overall trench, and not from the toe of the sloped portion. (e) Use of Tables. The members of the shoring system that are to be selected using this information are the cross braces, the uprights, and the wales, where wales are re- quired. Minimum sizes of members are specs if led for use in different types of soil. There are six tables of information, two for each soil type. The soil type must first be deter• mined in accordance with the soil classifica- tion system described in appendix A to sub- part P of part 1926. Using the appropriate table, the selection of the size and spacing of the members is then made. The selection Is based on the depth and width of the trench where the members are to be in- stalled and, in most instances, the selection is also based on the horizontal spacing of the crossbraces. Instances where a choice of horizontal spacing of crossbracing is avail- able, the horizontal spacing of the cross - braces must be chosen by the user before the size of any member can be determined. When the soil type, the width and depth of the trench, and the horizontal spacing of the crossbraces are known, the size and ver• tical spacing of the crossbraces, the size and vertical spacing of the wales, and the size and horizontal spacing of the uprights can be read from the appropriate table. (f) Examples to Illustrate the Use of Tables C-1.1 through C-1.3. (1) Example 1. A trench dug in Type A soil is 13 feet deep and five feet wide. From Table C-1.1, for acceptable arrange- ments of timber can be used. Arrangement #1 Space 4x4 crossbraces at six feet horizon- tally and four feet vertically. Wales are not required. 237 I Subpt.

Use of Tables C-2.1 through C-2.3 would follow the same procedu: es. (g) Notes for all Tcbics. I. Member sizes at spacings other than in- dicated are to be determined as specified in § 1926.652(c). "Design of Protective Sys- tems." 2. When conditions are saturated or sub- merged use Tight Sheeting. Tight Sheeting refers to the use of specially -edged timber planks (e.g., tongue and groove) at least three inches thick, steel sheet piling, or similar construction that when driven or placed in position provide a tight wall to resist the lateral pressure of water and to prevent the loss of backfill material. Close Sheeting refers to the placement of planks side -by -side allowing as little space as possi- ble between them. 3. All spacing indicated is measured center to center. 4. Wales to be installed with greater di- mension horizontal. 5. If the vertical distance from the center of the lowest crossbrace to the bottom of the trench exceeds two and one•half feet, uprights shall be firmly embedded or a mudsill shall be used. Where uprights are embedded, the vertical distance from the center of the lowest crossbrace to the bottom of the trench shall not exceed 36 inches. When mudsills are used, the vertical distance shall not exceed 42 inches. Mudsills are wales that are installed at the toe of the trench side. 6. Trench jacks may be used in lieu of or in combination with timber crossbraces. 7. Placement cf crossbraces. When the ver- tical spacing of crossbraces is four feet, place the top crossbrace no more than two feet below the top of the trench. When the vertical spacing of crossbraces Is five feet, place the top crossbrace no more than 2.5 feet below the top of the trench.

This appendix contain infor- mation that can be user] when aluminum hydraulic shoring is provided Li a method of prot(•rllon against cave-ins in trenches that do not exceed 20 feet (8.1m) in depth. This appendix must be used when design of the aluminum hydran lie protective system cannot to performed in accordance with 11926.652(c)(2). (b) Soil Classification. In order to use data presented in this appendix, the soil type or types in which the excavation is made must first be determined using the soil classification rnvthod set forth in appen- dix A of subpart P of part 1926. (c) Presentation of tgtorn:ation. Informa- tion is presented In several forms as follows: (1) Information is presented in tabular form in Tables D-1.1. D-1.2. D-1.3 and E- 1.4. Each table presents the maximum vertl• cal and horizontal spacings that may be used with various aluminum member sizes and various hydraulic cylinder sizes. Each table contains data only for the particular soil type in which the excavation or portion of the excavation Is made. Tables D-1.1 and D-1.2 are for vertical shores in.Xypes A and B soil. TablesD-1.3 and D1.4 are for hori- zontal waler systems in Types B and C soil. (2) Information concerning the basis of the tabular data and the limitations of the data is presented In paragraph (d) of this appendix. (3) Information explaining the use of the tabular data Is presented in paragraph (e) of this appcndix. (4) Information illustrating the use of the tabular data is presented in paragraph (f) of this appendix. (5) Miscellaneous notations (footnotes) re• garding Table D-1.1 through D-1.4 are pre- sented in paragraph (g) of this appendix. (6) Figures. Illustrating typical installa- tions of hydraulic shoring, are included just prior to the Tables. The illustrations page is entitled "Aluminum Hydraulic Shoring: Typical Installations." (d) Basis cnd limitations of the data. (1) Vertical shore rails and horizonta; wales are those that meet the Section Mod- ulus requirements in the D-1 Tables. Alumi- num material is 6061-T6 or material of equivalent strength and properties. (2) Hydraulic cylinders specifications. (I) 2 -inch cylinders shall be a minimum 2•inch inside diameter with a minimum safe work- ing capacity of no less than 18.000 pounds axial compressive load at maximum exten- sion. Maximum extension is to Include full range of cylinder extensions as recommend- ed by product manu(aturer.

(1) It is not Intended that the aluminum hydraulic specification apply to every situa• tion that may be experienced in the field. These data were developed to apply to the situations that are most commonly experi- enced In current trenching practler. Shoring systems for use in efcuations that are not covered by the data In this appcndix must be otherwise designed as specified in 1 1926.652(c). (Ii) When any of the following conditions are present, the members specified in the Tables are not considered adedua:e. In this case, an alternative aluminum hydraulic shoring system or other type of protective system must be designed in accordance with g 1926.652. (A) When vertical loads imposed on cross braces exceed a 100 Pound gravity load dis- tributed on a one foot section of the center of the hydraulic cylinder. (B) When surcharge loads are present from equipment weighing in excess of 20,000 pounds. (C) When only the lower portion or a trench is shored and the remaining portion of the trench Is sloped or benched unless: The sloped portion is sloped at an angle less steep than three horizontal to one vertical: or the members are selected from the tables for use at a depth which is determined from the top of the overall trench, and not from the toe of the sloped portion. (e) Use of Tables D-1.1, D-1.2, D-1.3 and D-1.4. The members of the shoring system that are to be selected using this informa- tion are the hydraulic cylinders, and either the vertical shores or the horizontal wales. When a waler system is used the vertical timber sheeting to be used is also selected from these tables. The Tables D-1.1 and D- 1.2 for vertical shores are used in Type A and B soils that do not require sheeting. Type B soils that may require sheeting, and Type C soils that always require sheeting are found in the horizontal wale Tables D- 1.3 and D-1.4. The soil type must first be de- termined in accordance with the soil classifi• cation system described in appendix A to subpart P of part 1926. Using the appropri- ate table, the selection of the size and spac- ing of the members is made. The selection is based on the depth and width of the trench where the members are to be trstalled In these tables the vertical spacing is held con- stant at four feet on center. The tables show the maximum horizontal spacing of cylinders allowed for each size of wale In the waler system tables, and In the vertical shore tables, the hydraulic cylinder horizon- tal spacing Is the same as the vertical shore spacing. 245 Subpt.

General. Attached are two change orders for the minisystem 15 sewer rehabilitation construction project performed by Building & Utility Contractors, Inc. 2. Summary of changes. Change order 1 is a no -cost change order which allowed pipe bursting as an alternative construction method to dig -and -replace construction, which was specified in the contract. Change order 2 is a reconciliation change order with a contract increase of $2,479.27, which reflects all final quantities and variations to the contract. All work has now been completed and waivers of lien received. 3. Budgeting. This contract was approved with a $56,390 contingency, of which none has been used to date. The $2,479.27 will come from this contingency. As these change orders complete the project, the $53,910.73 contingency balance should be returned to the sewer rehabilitation project, number 96012. 4. Staff Recommendation. The Staff recommends that the Mayor approve the two attached change orders.
