1.3 PROJECT BACKGROUND AND SCOPE

1.3.1 Background

1.3.1.1 General

The Natick Climatic Chambers Building was built in 1952, a single story structure, approximately 38,880 sq. ft. in size. The building is one of the oldest buildings on the NSSC base and includes two (2) climatic chambers. The building is located in the Cold War era historic district at Natick. Throughout the life of the building, there have been many updates to the electrical and mechanical systems, as well as modernizations to the exterior.

The original structure is of reinforced concrete and currently includes a black EPDM roof. The climatic chambers are constructed of painted metal, exposed to the elements. The chambers are showing signs of corrosion and have moss growing on the north facing exposures.

In 1993, the building shell, including the roof, was upgraded. The exterior walls were surfaced with the EIFS (Exterior Finish Insulation System) system with 2" of rigid insulation over the original concrete wall finish.

1.3.1.2 Location

The existing site is constrained on the north, east and west sides by existing roads and to the south by an existing parking lot, which will remain unchanged as a result of this project.

The original structure is of reinforced concrete and currently is enclosed by an exterior insulation finishing system (EIFS) and a multi-level black EPDM roof.

The existing punch windows and loading dock doors on the south elevation are original to the building. They do not provide a tight barrier and do not meet current AT requirements. The existing ribbon windows and storefront entry on the north elevation were replaced in 1993, however do not meet current AT requirements.

The climatic chambers are constructed of painted metal, exposed to the elements. The chambers are in good working order, but have corroded on all sides and are in need of treatment and repainting.

The building is currently in use and will remain occupied and functional for the duration of construction.
