c.Optional Types of Pipes. Provided a specific type of pipe is not specified by the plans or proposal, the Contractor will be permitted to install any of the optional types of pipe herein. Substitutions will only be allowed with hydraulically equivalent pipes. The hydraulic equivalence of optional types of pipes will be shown on the plans. Optional types of pipe shall meet the following criteria: Diameters less than or equal to 24 inches {600 mm} – P.C.; V.C.; 16 gage {1.6 mm} C.M. with greater than or equal to 24 inches {600 mm} of cover, 14 gage {2.0 mm} CM with less than 24 inches {600 mm} cover; or P.V.C., A.B.S. or HDPE, or PP pipe (HDPE and PP up to 36 inches {900 mm} diameter) with minimum of 24 inches {600 mm} of cover, and maximum of 25 feet {7.5 m} fill height. Diameters greater than 24 inches {600 mm} - Class 2 R.C.; V.C.; 14 gage {2.0 mm} C.M. ; P.V.C. or HDPE and PP(HDPE and PP up to 36 inch {900 mm} diameter) with a minimum of 24 inches {600 mm} of cover, and a maximum of 25 feet {7.5 m} fill height. Higher strength and/or coated finish CM pipe when required will be noted in the pay item. The Contractor may, at his option, substitute a higher grade pipe than specified or, with written approval, a cast iron or ductile iron pipe meeting the appropriate requirements of Section 854, provided no additional cost is incurred by the Department for such substitution. Any installation, once started, shall be completed using the same type of pipe unless specifically designated otherwise by plan details or requested and approved in writing.
535.03 Construction Requirements.
a.General. Construction details for installing side drain pipe shall be as specified in Section 530, except as modified in this Section. The requirements of Subarticle 530.03(b) for partial construction of fills in advance of trenching will not apply. Trenches shall be excavated as specified in Section 214. No separate measurement or direct payment will be made for excavation and backfill of trenches for side drain pipes. Special bedding will not be required; however, the pipe shall be bedded with ordinary care in the loosened soil foundation of the trench. Should the material at the elevation of the bottom of the pipe be ledge rock or other unsuitable bedding, it shall be excavated without additional compensation. The pipe shall be installed so that it will not vary at any point more than 1 inch {25 mm} from established line and grade. The pipe shall be backfilled in thoroughly compacted layers not more than 6 inches {150 mm} in thickness, using pneumatic tamps unless otherwise directed, but there will be no specific density requirements. Backfill shall be ordinary excavation material.
b.Testing for Excessive Deformation in PVC, HDPE, and PP Pipe. PVC, HDPE, and PP pipe shall be tested for excessive deformation. The test shall be performed by the Contractor in the presence of the Engineer. Testing shall be conducted no fewer than 30 days after the completion of the compaction of all fill over the pipe. The Contractor shall conduct the test by pulling a nine point mandrel through the entire length of the pipe by hand. The mandrel shall meet the following requirements: It shall be made of steel or aluminum; It shall have an effective diameter of 95 % of the nominal inside diameter of the pipe; It shall be at least as long as the diameter of the pipe; It shall be fitted with pulling rings at each end; It shall be stamped or engraved on some segment other than a runner with the pipe size and mandrel outside diameter. Prior to testing, the Contractor shall provide the Engineer with a proving ring to verify the mandrel size. The deformation is unacceptably excessive if the mandrel cannot be pulled through the pipe by hand without damaging the pipe. If the deformation is unacceptably excessive, the pipe shall be replaced without extra compensation. There will be no direct payment for testing.
535.04 Method of Measurement.
Side drain pipe will be measured in the same manner as specified in Article 530.04. Excavation and foundation backfill for side drain pipe will not be measured separately for payment, but the cost thereof shall be included in the contract unit price bid for the side drain pipe.
535.05 Basis of Payment.
a.Unit Price Coverage. Accepted side drain pipe, measured as specified above, will be paid for at the contract unit price per foot {meter} for the respective items, which shall be payment in full for furnishing pipe, excavating trenches, placing pipe, backfilling trenches, and for all tools, equipment, labor, and incidentals necessary to complete the work.

b.Laying Pipe. Pipe shall be handled so that there will be no loss or damage, before relaying. Pieces or sections of pipe found satisfactory by the Engineer shall be re-laid in accordance with the requirements of the appropriate sections governing culvert pipe. Special reference is made to construction details of Section 530 which are applicable to side drain pipe re-laid.
536.04 Method of Measurement.
Re-laid pipe will be measured in the same manner as specified in Article 530.04. Excavation and foundation backfill for re-laid pipe will not be measured separately for payment, but the cost thereof shall be included in the contract unit price bid for the re-laid pipe.

a.Unit Price Coverage.
1.The accepted length of re-laid culvert pipe, measured as noted above, will be paid for at the contract unit price bid for either roadway pipe re-laid or side drain pipe re-laid, regardless of size or type of pipe. Said unit costs shall be full compensation for the salvaging of the pipe in conditions for reuse and the re-installation of the pipe in accordance with the provision for roadway pipe as covered by Section 530 and Section 535 for side drain pipe including all equipment, tools, labor, and incidentals necessary to complete the work.
2.No payment will be made for the removal of existing pipe lines replaced by new or re-laid pipe, except for that portion of the old pipe removed outside the limits of excavation provided by Subarticle 214.04(a).
