560-4 Measurement and Payment
A.General Shoulder borrow will be measured in its original position or in the haul truck, as directed by the Engineer. No measurement will be made of material transported directly from unclassified excavation or fine grading and deposited directly in place on the shoulder. The quantity of shoulder borrow will be paid at the contract unit price per cubic yard for Shoulder Borrow , except as otherwise provided below.
5-27 (B) Measured in Original Position
The quantity of shoulder borrow to be paid will be the actual number of cubic yards of approved material, measured in its original position in the borrow source or stockpile by cross sectioning and computed by the average end area method, which has been incorporated into the completed and accepted work. No measurement wil l be made of any overburden or unsuitable material removed from the borrow source, nor of any material excavated before cross sections being taken.
C.Truck Measurement The quantity of shoulder borrow to be paid will be the actual number of cubic yards of approved material, measured in trucks, which has been incorporated into the completed and accepted work. Each truck will be measured by the Engineer and shall bear a legible identification mark indicating its c apacity. Load each truck to its measured capacity at the time it arrives at the point of delivery. The recorded capacity will be adjusted by making a 25% deduction to allow for shrinkage, and the adjusted capacity will be the quantity to be paid. When shoulder material is obtained as a result of fine grading operations, trenching out existing subgrade or shaping slopes and ditches, no direct payment will be made for the work of shoulder construction as such work will be incidental to the work of constructing the base or pavement. No payment will be made for the removal and disposal of any surplus material remaining in the stockpile after the shoulders have been completed. Where the borrow source has been furnished by the Department, payment for clea ring and grubbing the source will be made as provided in Article 200 -8 and payment for draining the source will be made as provided in Article 240- 4. Where the source has been furnished by the Contractor, no separate payment will be made for clearing and grubbing or draining the source as such work will be incidental to the work covered by this section. Payment for seeding and mulching all borrow sources will be made at the contract unit prices for the items established in the contract as payment for the w ork of seeding and mulching.
