ABSTRACT
The federal acquisition regulation (FAR) provides a good starting point to understanding contract options in the government or commercial environmental restoration arena. There are four general contract types available under FAR: fixed price, indefinite quantity, time and material, and cost reimbursement. The macroengineering systems developed should have reserve throughput capacities that allow their system components to meet unforeseen expansion of expected waste volume without impacting overall schedule. The productivity, cost, and schedule estimates are based on assumptions of certain operations being performed and are affected by certain cost and schedule drivers. Productivity, cost, and schedule projections are based on a number of parallel operations occurring simultaneously: Overburden removal operations, Excavation/demolition operations and sorting operations. The most significant cost driver in groundwater remediation will be the selection of options. The significant chance of unforeseen changes in equipment scheduling and procedure supports the factoring of significant allowances into the cost estimates.
