In May 2015, Sierra Construction successfully completed the 28,000 sq ft tilt-up building with full build out for Nautilus Inc. The TVA designed tilt building is mostly clad in a prefinished concealed fastener metal panel system. This building also has a large amount of storefront requiring a special double thermal break storefront system to meet energy code. The exterior design of the building provides a visual appealing tilt up in an area where plain concrete and brick façades are the norm. This building will house Nautilus’ research and development team as well as testing equipment. Roughly half of the space is for offices and the other half is “warehouse” space, housing all the equipment Nautilus needs to design, build and test their equipment. The R&D facility required special coordination of electrical circuitry and connections for 70+ pieces of equipment. It also required a compressed air system for pneumatic tools and test equipment. Construction began the first of November 2014 and was turned over to Nautilus for operation on May 8th.
