Whitley Evergreen (Marysville, Washington) partnered with Advanced Technology Construction (ATC) to complete the CDC. But, first, there were two significant challenges for this project; restricted access to the job site and strict requirements for the USGBC LEED Silver certification. But, this would not be unfamiliar territory for either Whitley Evergreen or ATC. Despite challenges from the poor soil conditions, there was little effect on the construction schedule. The work continued indoors uninterrupted from the weather. Once the modules were delivered and set, ATC constructed the pitched roof and made final finishes on site. The completed building features an attractive design, sustainable finishes and efficient systems.
