The equitable adjustment amount will be $9,735.80 to account for costs associated with purchasing the additional pipe and renting and shipping the pipe ramming collet (see attached cost breakdown). Therefore, the change in the contract amount for this bid item is -($22,800.00) + $9,735.80 = -($13,064.20) i Bid Item No. 11 -- Stabilized Construction Entrance The original quantity for Stabilized Construction Entrance was 424 SY.
