Nashville Hangar Project - International Airport (BNA)

J&S Construction led the Design-Build team on this 27,797 square-foot airplane hangar for two internationally famous country music stars at the Nashville International Airport. The project consisted of a 16,000 square-foot hangar, office space, maintenance garage, kitchen, site work, parking, storage, bunk rooms and a fuel farm.

The budget was a major factor in this client deciding to use J&S Constructions’ Design-Build approach to construction. In the preliminary design phase, J&S Construction worked closely with the Architect of Record to ensure the budget was going to be met. As the Architect of Record made design decisions, J&S Construction completed conceptual estimating and provided suggestions to ensure all constructability issues were addressed in the preliminary design of the building.

This estimating guaranteed the owner’s budget was not only met but reduced by more than 20 percent.

The high ceiling height and large open area of the hangar bay made it a perfect candidate for a high-efficiency radiant floor heating system. The radiant floor heating system is a low-temperature system that uses the concrete floor slab as a radiator to deliver heat at the floor level. This system is designed to heat the occupants and objects in the space directly, and not the air in the space as a forced air system does, potentially providing significant energy savings over forced air systems.

The radiant floor system heats the floor slab by distributing heated water to the floor slab through a series of cross-linked polyethylene (PEX) piping loops embedded in the slab. The PEX loops are in turn connected to one or more distribution manifolds above the slab. A high-efficiency hot water boiler and circulation pump are used to heat the water and distribute it to the manifolds. Water distribution to each manifold is controlled using smaller zone pumps to provide additional zoning and temperature control based on occupant needs. Utilizing this system for the hangar bay allowed J&S Construction to provide a heating system that is not only energy-efficient but is quiet, with minimal mechanical equipment in the occupied space.

Once construction began, the act of maintaining an aggressive schedule was an important goal for the owner. J&S Construction was able to meet this aggressive construction schedule by using the measurable processes they have in place for all projects.
