Tacoma Cascade Pipeline | Cascade Water Alliance
Location: Pierce and King Counties, WA
Final Cost: $8 Million
Completion Date: 2009
Scope: Construction Management,
Engineer: SCI Engineering
As both the Project Manager and Owners Representative, Hainline managed the Tacoma Cascade Pipeline (TCP) project that stretched from Lake Tapps to Issaquah, Washington. Hainline’s scope began with an in-depth operation/construction procedure overview and an evaluation of the existing program. The evaluation focused on reporting mechanisms, constructability reviews, risk assessment, control packaging, project controls, public outreach, and bid phases.
A significant effort was spent evaluating the construction management (CM) plan, which included evaluation of the methods & controls of the CM contract, the design and engineering contract, cost control process/reporting, billing process and documentation, schedule control process, and the overall planning schedule and control. From this analysis, Hainline made recommendations to the Cascade Water Alliance (CWA) in revising the management approach.
Hainine assisted CWA in analyzing the GC/CM process as an alternate delivery system. Ultimately, the projected demands dropped and due to CWA’s ability to contract with the Seattle Water District, the TCP expansion plans (with the exception of the 1.1 mile SR-900 portion) was archived. Hainline played an active role in the archiving effort, including addressing status of design, closing out right-of-way agreements, and terminating permits. The TCP project was archived and is awaiting future use when the need arises.
