No measurement will be made for removal of any materials beyond that indicated on the contract drawings and tolerances described on the plans and in the specifications.

The Contractor shall sound the riverbed over the area to be excavated by a method and with equipment acceptable to the Contracting Officer. Any areas not conforming with the specified tolerances shall be corrected and resounded, at the Contractor's expense. The Contractor shall perform additional soundings as necessary during the progress of the work to verify depths. All sounding data shall be furnished to the Contracting Officer promptly after the information has been obtained and compiled.

However, no measurement for payment will be made for any material over-excavated beyond that permitted by the allowable tolerances for the specified bottom elevation or specified side slopes.

Unless otherwise specified and/or approved, quantities shall be calculated

SECTION 01 22 00.00 10 Page 11 in cubic yards by the average end area method based on the initial and final soundings. The Contractor is responsible for any additional excavation required to bring the area within the tolerances specified or shown prior to beginning any work upon which the excavation depends at no additional cost to the Government, and no additional measurement or payment will be made for such additional excavation.
