This task provides programmatic oversight for the construction related activities or the Program including, Site Construction Management (CM) Services for the Wastewater Treatment Plant Upgrade and Expansion Project. Due to project delays, completion tasks such as startup and commissioning increased beyond the original estimate resulting in a higher level of effort required for Site CM Services. This task captures the cost of the increased level of effort for these services during Year 11 of the contract term and the two outstanding invoices for a total of 1,345,733.93.
