1989: Sailboats to Museums

TriPyramid evolved, in large part, out of the sailboat rigging industry. Our founders, Tim Eliassen and Michael Mulhern, were directly involved in the production of America's Cup racing yachts and used that technology to help I.M. Pei and NCK Engineering design and manufacture the hardware that supports the Grand Pyramid at the Louvre.

Tension Assemblies and Intricate Hardware

While working on the Louvre, we discovered that the architectural world needed structural hardware that was unobtrusive but elegant, and it became our modus operandi to fill that niche. We developed our standard tension element product line - still a foundational part of our business today - but found that bespoke fittings were also necessary to fulfill our client's needs.

Complex Hardware Systems and Fabrications

The solutions we create rely on aerospace machining tolerances, an ever-expanding understanding of materials science and ardent dedication to craftsmanship. These skills were critical in the creation of our first small-scale components, and we find that they are just as essential to the success of complex systems and fabricated parts.

Large Precision Fabrications and Complete Building Components

Sometimes, our projects provide a platform for the creation of objects that are a combination of sculpture, engineering, and machine design. To continue achieving the levels of fit and finish our clients were demanding, but at new scales, we learned that massive parts must be constructed with the same level of precision and attention to detail as any other piece of hardware. If we found that we didn't have the capacity, we expanded. Where the capability didn't, exist we created it.

Today and Tomorrow

One of our most ambitious projects to date was the new stair and elevator at the recently re-opened 5th Avenue Apple Store in New York. To meet the challenges presented by the client and the design team, we invested in new machines, inspection tools, and advanced training for our team members. We learned a great deal and look forward to learning more so that we can continue to reimagine what is possible in the built environment.
