"Keeping our Fleet Fit to Fight"

Building 155 is a prominent industrial workshop located in the historic Pearl Harbor Naval Shipyard. Designed by industrial architect Albert Kahn and constructed in 1941, the original building served as a space to offer ship maintenance support to the Navy Fleet’s Mid-Pacific Theater. In order to showcase the pride of the shipyard while reflecting its motto “Keeping Our Fleet Fit to Fight,” MASON created a new safe and comfortable work environment that meets historic preservation requirements.

We repaired deteriorated window mullions, steel girts, metal supports and concrete sills while maintaining the building’s historic, character-defining features. We also worked with the original steel window manufacturer to custom design and fabricate over one thousand windows to match the size, configuration and profile of the original windows and uphold its historic integrity. The window profiles are now a standard in the manufacturer's product line.
