A Challenging Fire Station

Snow retention system proves easy choice for award-winning project

Dynamic Fastener Case Study Aug18

When Steve Moore, owner of MMS Northeast Inc., Hampton Falls, N.H., was awarded the Martha’s Vineyard Airport Fire Station project in West Tisbury, Mass., he knew there would be some challenges. The job was located 15 miles offshore in the Atlantic Ocean, and the only way to deliver men and material was via a one-hour ferry ride each way. The erection crew made the one-hour trek to and from the job site every day.

The building consisted of 128 tons of steel. It has multiple roof planes and varying roof pitches, with hip and valley conditions. Moore found a way to overcome these challenges and more. The final result was the project being awarded the highly coveted 2017 Building of the Year honor from Chief Buildings, Grand Island, Neb.

The one aspect of the job that Moore knew would not be a challenge was the snow retention, DYNA-GUARD by Dynamic Fastener, Raytown, Mo. DYNA-GUARD is a rail-style snow retention system.

The DYNA-GUARD system consists of the following:

  • DYNA-GUARD aluminum rails are 8-foot T-shaped rails available in inpunched, or punched at 4-inch, 6-inch and 8-inch punched spacing.
  • DYNA-CLAMPS, eight styles of DYNA-CLAMPS with round point set screws are available to accommodate many different roof profiles.
  • SNO-DAMS, are used to inhibit the ability of snow and ice to slide under installed DYNA-GUARD.
  • All DYNA-GUARD components are extruded from aircraft-quality, high-tensile 6005A T61 aluminum. More DYNA-GUARD information can be found on ARCAT.
  • The DYNA-CLAMPS have been independently tested on numerous of the most popular metal building and architectural standing seam roof profiles.

The MMS team installed over 500 feet of DYNA-GUARD on the Martha’s Vineyard Airport Fire Station project. When asked about the DYNA-GUARD system, Moore comments, “MMS Northeast has been exclusively utilizing DYNA-GUARD snow retention on all our metal roofs since 2015. With over 180 projects all across the United States, on roof pitches from low slope up to 10:12 pitched roofs, we have found the DYNA-GUARD system to be extremely reliable and easy to install. We have never had a report of damage or call backs due to DYNA-GUARD not performing as intended.”

Moore also adds, “The support from Tim Harms and the rest of the Dynamic Fastener team in assisting with design, product selection and timely delivery has helped MMS provide our clients with reliable metal building systems.”

MMS has found other uses for the DYNA-CLAMP on its standing seam metal roofs to prevent damage. See illustration (above left) for keeping gas lines attached to roof without damaging the panels.
