COH - North East Water Purification Plant
PROJECT DESCRIPTION
This Project involved performance of Owner Representative Services in connection with the design and construction of the Phase 1 and Phase 2, 80-MGD Northeast Water Purification System. This system of improvements was needed to alleviate subsidence by treating and distributing surface water and reducing the region’s dependence on groundwater. The design, construction and operation of the Northeast Water Purification System was implemented using the Design, Build, Operate approach of project procurement. The scope of services performed on this project included the following: verifying compliance with all applicable design criteria; verifying acquisition of all required permits; reviewing design documents for constructability purposes; and monitoring performance and schedule compliance during construction. The following portions of the project were included in the scope of services: the Raw Water Intake Structure; the Raw Water Pump Station; 9,000 linear feet of 66-inch diameter raw water pipeline; 31,000 linear feet of 84-inch diameter waterline; and, 25,000 linear feet of 42-inch waterline.
Phase 2 of this project involved the performance of Owner Representative Services in connection with the construction of the Phase 2 Expansion of the 40-MGD Northeast Water Purification Plant. The expansion of this facility was needed to meet the North and West Harris County Regional Water Authority’s Groundwater Reduction Plan requirements. The primary facilities constructed in the expansion included the following: one new 15-MG Ground Storage Tank; four additional flocculation basins; four additional sedimentation basins; eight new dual media filter basins; one new clear well/transfer pump station; one new chemical storage and delivery system; one new ultraviolet disinfection building with five reactors; one new sludge thickener; one new belt press; upgrades to the high service pump station; and, upgrades to the raw water pump station. The scope of services performed on this project included the following: reviewing design documents for constructability purposes; monitoring performance and schedule compliance during construction; recommending payment of monthly requests based on the schedule of values and the work performed each period; and, reviewing/negotiating change orders.
