DEA provided engineering design, construction administration and permit coordination services for this $100 million renovation to the multimodal grain terminal owned and operated by the Tacoma Export Marketing Company in Kalama, Washington. This 20-acre modernization project, for which DEA provided civil engineering and permitting services, involved constructing a system of 200-foot tall towers, foundations, silos, conveyors, shiploaders, barge unloaders, bulk weighers and other facilities to modernize the terminal, plus demolition of selected facilities within the complex. All portions of the complex are now connected by an electrical and communications duct bank, and a new fire suppression loop and 300,000 gallon tank was installed, along with a new drainage system that utilizes an existing outfall to the Columbia River.

As the project’s designated contact with Cowlitz County, the permitting authority, DEA not only provides the civil design but also coordinates the permit applications from many design disciplines, including electrical, fire suppression, and structural engineering firms who were each tasked with portions of the project design. DEA operated in the design-build environment to build consensus among the various parties—owner, contractors, designers and reviewers—to gain permit approval for the many phases of the work. DEA’s design role include coordinating underground utilities as well as designing the water system, drainage system, roadways, parking, and site grading. DEA also provided railroad design services for the expansion of the existing rail yard and the addition of several spur connections to the BNSF railroad on Port of Kalama property.
