No separate compensation associated with concrete materials testing, as part of the Contractor's Quality Control, will be made and these costs shall be incidental to concrete construction. No payment will be made for concrete wasted or not otherwise placed during production.

1.2.2.2 Measurement

Pay lines for tunnel liner are based on the neat lines of the structures as shown on the drawings. Concrete will be measured for payment based upon the actual volume of concrete within the pay lines of the structures as indicated on the drawings. Measurement of concrete placed against the sides of any excavation without the use of intervening forms shall be made only within the pay lines of the excavation or surface to be constructed.

No measurement will be made of concrete placed outside the tolerances specified for the excavation unless otherwise approved by the Contracting Officer. No deductions shall be made for rounded or beveled edges, space occupied by metal work, electrical conduits or reinforcing steel, nor voids
