Knox Hall has served Fort Sill, Okla. for nearly 70 years. Now home to the U.S. Army Training and Doctrine Command (TRADOC), the two-story building hadn't been remodeled since an addition in 1962. Garver and The Ross Group redesigned the second floor and made improvements to help the TRADOC continue its mission.
The renovation provides staff with private offices, upgrades rooms for secure classified conversations and improves restroom facilities. Garver worked as a subconsultant with The Ross Group on this design-build project and provided structural, mechanical, electrical and fire protection design. Charles D. Foster, Architect, P.A. provided architectural design as a Garver subconsultant.
"With renovation projects, especially ones that haven't seen a remodel in 50 years, you don't know what you're going to face until you've exposed the walls," said Garver Project Manager Mike Morgan. "There are often issues with codes, constructability and efficiency that need to be addressed."
The renovation tackled the second floor's 55,600 square feet and involved ceiling, wall and floor removal, antiterrorism/force protection measures and new interior construction. In addition to the facility upgrades, the building required asbestos abatement and lead-based paint removal.
"Garver developed a demolition and abatement plan that allowed The Ross Group to start work on the project early," said The Ross Group Project Manager Brian Beck. "This also facilitated an inspection of the entire building without the ceilings and wall partitions to develop documents that minimized the need for changes after design."
Upgrades were also made to bring the building into compliance with various regulations, including the National Fire Protection Association's Life Safety Code, the Americans with Disabilities Act and antiterrorism requirements.
The building's second-floor windows were removed and replaced with blast-resistant panes to meet U.S. Department of Defense antiterrorism/force protection standards. The blast framing was tied directly into the building's superstructure.
The electrical systems, including power, lighting, telecommunication and fire alarm, were demolished, removed and upgraded. The design included performing an arc flash, short circuit and coordination study. This ensured that the new equipment met available fault current conditions and that overcurrent devices were coordinated in the new distribution system equipment. This also allowed Garver to make recommendations for improvements in other existing power distribution system equipment that were not part of the project's scope of work.
All HVAC ductwork and air devices were replaced, and new variable volume air handling units were installed.
Fire protection improvements involved replacing the dry-pipe sprinkler system and installing new systems for the fire alarm and mass notification.
The project was one of 30 repair and sustainment projects at Fort Sill funded with American Recovery and Reinvestment Act of 2009 dollars.
