Rock Island, IL
Building 250 is constructed of reinforced concrete with steel sash windows and is located on the Rock Island Arsenal, the largest government-owned weapons manufacturer arsenal in the Unites States. The Arsenal was originally established as a government site in 1816.
The Rock Island Arsenal Development Group (RIADG) retained Shive-Hattery to perform a building condition study for the 71,600 square feet high bay area located on the first floor of Building 250. Shive-Hattery also provided architectural and civil, structural, mechanical, and electrical engineering design services for the building renovation.
The study included review of architectural, structural, HVAC, plumbing, and electrical systems. Shive-Hattery had also previously conducted an asbestos and lead paint survey. Both studies were used to provide information for the building renovation. The study followed Rock Island Arsenal guidelines to maintain the historic nature of the building.
Building renovations included:
- Asbestos abatement including removal of insulation from the steam piping systems
- Lead based paint abatement including removal of all loose and flaking paint throughout the 71,600 square feet
- Building exterior renovation in accordance with historic preservation guidelines that included window replacement, wall repairs, and painting
- New energy efficient windows with profiles to match the removed steel sash windows
- Roofing system improvements including removal of the built-up roofing systems applied over reinforced concrete deck at the low-bay areas; replacing the original, deteriorated, pyrobar gypsum deck with new steel deck in the high-bay areas; and installing a fully adhered EPDM membrane system over rigid insulation and vapor barrier throughout
- Exterior walls were furred-out and insulated
- Office, locker room, and mechanical spaces were created in the south low-bay area
- The existing dock area was expanded to provide two dock spaces
- New natural gas, electric, domestic water, and fire protection utility services were extended in to the building
The building envelope improvements and the selection of high efficiency mechanical and electrical systems allowed the renovated portions of the building to exceed the Energy Policy Act (EPAct) requirement (30% more efficient than a baseline building for ASHRAE 90.1-2004). Other MEP improvements included:
- Per the Rock Island Arsenal request, removal of the building heating from the central steam plant
- Two, one million BTU, gas-fired, hot water boilers were installed to provide heating for the remodeled areas
- Hot water finned-tube radiation was installed along the building perimeter
- Three, 9,900 CFM air turnover/heating units were installed in the high-bay area to bring in outdoor air and provide general heating
- Ceiling fans were installed throughout the high-bay to improve air circulation and prevent stratification of air
- A variable air volume (VAV) air handling unit with hot water preheat coil, direct expansion cooling coil, and VAV boxes with hot water reheat coils were installed to provide comfort conditioning in the offices and locker rooms
- A 15 ton condensing unit was installed on the roof
- A dry-pipe sprinkler system was installed throughout the renovated area
- A new 13.8 KV electrical service was extended to the building, and a 1,000 KVA 13.8KV to 480/277 volt transformer was installed in the building
- A 277 volt lighting and a fire alarm system were installed throughout the renovated area
