PROJECT SIGNIFICANCE: The Bonneville Power Administration鈥檚 new Technical Services Building supports maintenance, testing and repairs to maintain modern electronic transmission communications and controls. The three-story structure helped BPA avoid $85 million in upgrades to the 80-year-old building it鈥檚 replacing and contributed to savings of hundreds of thousands of dollars per year in avoided lease costs, Thane Miller, BPA鈥檚 Ross Complex redevelopment program architect and manager, stated in a news release.

A prefabricated building enclosure system was installed for the聽building. Use of a progressive design-build project delivery method streamlined incorporation of prefabricated elements, reduced the construction timeline by two months, and saved more than $1 million in the overall budget.

As part of the preconstruction planning process, design-build team members explored ways to maximize their respective strengths to provide the greatest value possible; the result was an early decision to use prefabrication. After evaluating seven types of enclosure systems, the team opted to leverage Western Partitions鈥� ability to fabricate fa莽ade panels at its facility within 10 miles of the project site.

Each building panel is unique. One set covers the first floor, and another set of two-story panels up to 42 feet tall encloses the upper floors. Metal-stud frame assembly was used with fiber-cement panels and articulated metal panels with ribs. Only specific areas 鈥� such as under structural steel canopies and within them 鈥� were conventionally framed.

Western Partitions recently received a Northwest Wall and Ceiling Bureau Project of the Year Award (exterior 鈥� commercial category) for its work on the project.

Miller credited the project with establishing momentum for BPA鈥檚 use of progressive design-build for other Ross Complex projects over the next several years.

鈥淭he TSB project is a significant pilot project, carving BPA鈥檚 path into the progressive design-build project delivery method,鈥� Miller stated. 鈥淭his project is helping change the status quo within BPA鈥檚 procurement methods, giving us additional tools for more collaborative contractual partnerships and allowing us to realize improvements in the management of project resources and processes.鈥�
