Trident Aquatics

Koehn Trident 01 | Construction Management

Construction Type: Hybrid: Conventional construction and pre-engineered metal building

Special Features: Interior - Two pools with a combined 220,000-gallon capacity; custom-treated steel beams; custom building coatings and surface treatments; high-capacity dehumidifying HVAC system | Exterior - Exterior insulation and finish system (EIFS), masonry, architectural metal panels

The young athletes of Trident Aquatics, a sanctioned USA Swimming team, needed a state-of-the-art training facility that could double as a community aquatics center for the region. When it was time for Sean Callan, founder and coach, to make the new business a reality, he called on Koehn Construction to deliver the right solutions.

Creativity and collaboration drove the project. Callan and Koehn, partners on previous builds, brainstormed on ideas, leveraging Koehn’s experience with out-of-the-ordinary assignments to create a solid plan. And by collaborating with Cassandra Taylor of Architect One, Koehn was able to deliver a cost-effective solution for the building.

Koehn wasn’t afraid to do the research, and by the time we began construction, they knew everything about the building and what was required.
