McChord Runway Bridge Dewatering Project

Joint Base Lewis-McChord (JBLM), located just 15 miles southwest of Tacoma, Washington, is one of the nation’s most strategically important military installations. In 2020, critical repairs were required on the Barnes Blvd. Bridge to address serious infrastructure concerns that posed risks to both operational readiness and national security.

During a routine inspection in January 2020, significant ground depressions were discovered near McChord Field’s runway. Further investigation revealed the failure of two massive 12-foot diameter, 1,800-foot-long steel culverts that had been in place since the 1950s. This structural failure directly threatened the stability and safety of the runway—a vital component of JBLM’s mission-critical operations.

In response, an expedited emergency infrastructure plan was implemented. The solution involved replacing the deteriorating culverts with a new concrete arch bridge capable of withstanding a 100-year storm event—doubling the capacity of the original 50-year design. The new system was also engineered to support the natural flow of Clover Creek, enhancing both environmental sustainability and long-term resilience.

This large-scale effort required significant excavation and complex dewatering operations to meet strict design specifications. RAM GeoServices, Inc. played a critical role in the success of the project by providing geotechnical consulting, site observations, subsurface testing, engineering calculations, and documentation review throughout the construction process.

With deep experience supporting high-security and federal infrastructure projects, RAM GeoServices ensures full compliance with military and federal standards. Our team remains committed to delivering reliable, expert-driven solutions for mission-critical environments—bringing the same level of precision, urgency, and professionalism to future work at JBLM and other federal sites.
