Sellen’s restoration of the Naval Reserve Armory on Lake Union provides the Museum of History and Industry with 10,000 square feet of additional exhibit space.
During construction the team discovered the building sloped 15 inches from the southwest corner to the northwest corner. The majority of the architectural elements were installed parallel to the floor, ceiling and windows, all of which sloped. In contrast, many construction systems including the mechanical piping, doors and chilled water system were installed level, with no slope.
Sellen scanned the building using a high-definition laser to aid in the development of a detailed 3-D model that provided the Sellen team with a platform to craft constructible solutions with confidence.
Originally targeting LEED silver, MOHAI challenged the team to achieve LEED platinum while in the middle of construction. The Sellen team met the challenge, and MOHAI is the first LEED platinum museum in Washington state, and one of only a handful in the country.
