Joint Base Lewis-McChord

Scope of Work:

Central has a history of performing work with the United States Army Corps of Engineers (USACE) across the country, especially up and down the West coast where our main office is located. Due to our status as a Sevice-Disabled Veteran-Owned Small Business, we appreciate opportunities that arise to work with military organizations and establishments. These factors made traveling north to perform work with Bradford Consulting Engineers on the grounds of Joint Base Lewis-McChord (JBLM) a natural fit for Central.

When reaching out to Bradford Consulting Engineers, the Joint Base was interested in adding amenities to a previously existing building on site. This project was scoped to include demolition of existing structures and construction of new recreational facilities and associated site improvements. These facilities include both a basketball and volleyball court, to provide recreational options for those lodging at the base.

Central was scoped to perform preliminary evaluation of the surface and subsurface conditions, and provide preliminary geotechnical engineering conclusions and recommendations for use in the design and construction phases of the project. After performing a geological review and evaluating available site information such as well logs and mapped landslides, we conducted our subsurface investigation on-site through three exploratory test pits and evaluated drawdown rates using standardized infiltration testing in two locations. A geotechnical report was generated from the data acquired from our investigations, and passed along to Bradford for consideration during the project’s design phase.

As the project moves towards breaking ground in the construction phase, Central Geotech is preparing to return to JBLM for the purpose of providing construction observation services. For a project like this, we will be looking to secure one of our engineers’ approval on the competency of in-situ native subgrade soils, perform density testing of compacted backfill once excavation is complete, and provide guidance and engineering recommendations as necessary.

Results:

This project has so far represented an incredibly successful partnership, and is a great example of the work we’d like to continue performing in the future. We hope that performing well on these types of projects will serve to both better the military community at large and strengthen the relationships we are developing within it.
