On: Nov 04 2016.

Government Response. . The riprap should be installed such that is lies against the downstream face of the corewall, creating a wedge of riprap to dissipate energy from falling water before hitting the articulated concrete blocks. The concrete corewall is to be cut down in 1 foot increments starting from elevation 627 to

623. The riprap letdown should be installed as the corewall is cut down to elevation 627. As the corewall is incrementally cut down, rip rap above the cutdown elevation should be removed to allow clear flow path over the corewall, onto riprap, and down the spillway.

7. The response to Question 6710273 states that Mobilization costs are paid in full upon completion of work. Implicit in this position is the need for the contractor to finance all mobilization costs that it has elected to include in the item for the 2-year project duration. Typically Offerer sees terms that provide for at least two disbursements of mobilization costs. The first large disbursement (75% to 80%) at completion of initial mobilization activities (perhaps a month or so into the project) and the remainder at overall project completion. Please reconsider the stated payment provision.
