MacDonough Hall at the United States Naval Academy

Built in 1903, the 128,000 square foot MacDonough Hall serves as a training facility for Navy and Marine Corps Officers.  The six floor, granite and steel, building includes space for swimming, personal defense, recreational sports, wellness, fitness testing and more.

Encore Sustainable Architects is currently providing Architectural Quality Control Services for Consigli Construction to help preserve historic features impacted by the $41M renovation of the Hall.

Renovations will include: replacement of the pool, HVAC, electrical, and fire alarm and suppression system; abatement services; repairs to exterior, envelope, plumbing and drainage; and improvements to the overall structure and interior architecture.

As part of our work, we review and serve as quality control on a variety of projects. Shown here is the repointing of the building masonry with masonry restoration subcontractor, Worchester Eisenbrandt Inc  The building was last repointed in the seventies.  Since then, the mortar between the granite blocks has deteriorated. Repointing removes the damaged mortar and replaces it to ensure solid weatherizing of the building as well as address cosmetic issues.

Another project involves micro abrasive blasting. Similiar to a sandblast, this type of cleaning uses low pressure – 30psi – vs high pressure to gently mix water, air and micro abrasive glass powder to remove stains and calcite without damaging the granite.
