measured along the centerline of such connection. An additional 2 lft of pipe of the same diameter as that of the elbow will be included for each such connection. If increaser or reducer connections are made, measurement will be made on the basis of the larger diameter pipe for the full length of the section forming such 520 connections. Structure backfill will be measured in accordance with 211.09. Flowable backfill will be measured in accordance with 213.08. Pavement replacement a nd subbase necessary due to structure placement under an existing pavement will be measured to the neat lines shown on the plans. For structures for which the plans show pipes of differing sizes for either smooth, semi-smooth or corrugated interiors, and either the semi-smooth corrugated interior 530 alternate is installed, measurement of structure backfill or flowable backfill will be based on the neat line dimensions shown on the plans for the smooth interior alternate. Grated box end sections will be measured per each for the specified type, surface slope, and pipe size. Video inspection for pipe will be measured by the linear foot as determined by the electronic equipment. Geotextile used for backfill material will not be measured for payment. 540
715.14Basis of Payment
The accepted quantities of pipe and pipe extensions will be paid for at the contract unit price per linear foot for pipe of the type, shape, and size specified, complete in place. Where used other than as a roadway dr ain casting extension pi pe or as a bridge deck drain system, cast iron soil pipe will be paid for at the contract unit price per pound for the diameter specified. Pipe end sections, concrete anchors, and safety metal end sections will be paid for at the contract unit price per each for the size specified, complete in place. A concrete 550 anchor attached at one end of twin pipes will be paid for as two concrete anchors. A concrete anchor attached at one end of triple pipes will be paid for as three concrete anchors. Roadway drain casting extension pipe will be paid for at the contract unit price per each.
Pavement replacement necessary due to structure installation under an existing pavement will be paid for at the contract unit price per ton of HMA for structure installation of the type specified and per square yard for PCCP for structure 560 715.14 746 installation. Subbase will be paid for in accordance with 302.09.
Structure backfill will be paid for in accordance with 211.10. Where used as a substitute for structure backfill, flowable backfill will be paid for as structure backfill. When specified for pipe backfill, flowable backfill will be paid for in accordance with 213.09. If a pipe structure is lowered, relocated, or if unsuitable material is encountered so that additional excavation is necessary over and above that shown on the plans at the original location, such additional excavation will be paid for at three times the 570 contract unit price for the class of excavation involved. If the contract does not include rock excavation or unclassified excavation, rock removal below the proposed trench bottom elevation will be paid for at three times the contract unit cost for common excavation. However, in each of the above cases, such excavation will not be paid for if the additional amount involved at such structure is 10 cu yds or less. For structures for which the plans show pipes of differing sizes for smooth, semi-smooth or corrugated interiors, and either the semi-smooth or the corrugated interior alternate is installed, payment for pipe backfill will be made based on the neat line dimensions shown on the plans for the smooth interior alternate. 580
Grated box end sections will be paid for at the contract unit price per each for the specified type, surface slope, and pipe size. Video inspections for pipe will be paid fo r at the contract unit price per linear foot completed. Payment will be made under: Pay Item Pay Unit Symbol 590
