The Contractor shall make the needed investigation and determination of existing and anticipated conditions concerning care of water. Plans for diversion and care of water during construction of the structure shall be submitted, within 10 calendar days after receipt of Notice to Proceed, for the approval of the Contracting Officer and shall show location, material and method for dewatering the work area and disposal of the water. The area to be occupied by the new structure shall be unwatered and maintained in a "dry" condition until the concrete slabs and walls have been placed satisfactorily and cured in an approved manner. Diversion of the water shall be accomplished without additional disturbance of in-place bank material beyond the limits necessary for placement of the structures.

1.4.1 Payment

Payment for diversion and care of water will be made at the contract lump sum price for "Diversion and Care of Water," which price shall constitute full compensation for all costs of diversion and care of water.

1.5 DRAINAGE

The Contractor shall provide and maintain ditches, dikes, and other facilities within and adjacent to the work areas, to divert water from surface and subsurface flow away from work in place or under construction by this and other contracts to prevent damage and interference. The basis for design, location, type and size of drainage facilities are subject to review and approval prior to construction.

1.6 Project Survey and Layout

In addition to the requirements of FAR 52.236-17 Layout of Work, the Contractor shall provide a licensed land surveyor to check initial project control, and to provide and set hubs for project construction. The Contractor shall use (and reference in all as-built data) project stationing as described on the contract drawings. In addition, a licensed land surveyor shall provide final project embankment survey (i.e. to include major breakpoints, riverward toe, profile, top of levee at riverward/landward and landward toe) prior to placement of surfacing for government review and approval. If applicable a licensed land surveyor shall also provide, set and verify as built condition of major flood control structures/features; i.e. flood wall control. These surveys shall provide and verify both horizontal and vertical project control. This survey shall be used for final as-built embankment profile and cross section, and major flood control structure records, and recorded on the as-built condition in accordance with Section, As-Built Drawings.
