Bryan Hall Building 6901

Renovations to the 110,000 SF Bryan Hall consisted of site assessments, interviews, programming, and design to completely renovate an existing 1960’s training building.

- Location: Keesler AFB, MS
- Project Size: 110,000 SF
- Cost: $18,600,000
- Facility Type: Government
- Owner: US Air Force
- Services: Electrical Engineer

The exterior renovations included a new lightning protection system, site lighting, new roofing, hardening the facility in accordance with FEMA Shelter requirements, and ATFP compliance upgrades. A complete interior renovation was performed to meet current programmatic needs, including new training spaces, offices, breakrooms, auditoriums, and support spaces. New mechanical, electrical, and telecommunications systems and spaces were provided to support the renovation.

Bryan Hall serves as a mission critical Information Technical Node (ITN) to the Keesler AFB training wing. This ITN serves 40 training facilities via fiber optic backbone. The existing deficient, and inadequately sized ITN was replaced with a new ITS space central to the facility and designed to meet the base’s space, security, and redundancy requirements. The design was closely coordinated with the 81^st Communications Squadron to enable the construction of the new ITN and relocation of the ITN equipment to be performed with minimal downtime, eliminating any disruption to the base’s training mission. This phasing effort also involved phasing the electrical service replacement to maintain power to the ITN throughout the renovation. New electronic access control and IP based CCTV systems were also provided throughout the facility. The building telecommunications system supported three separate non-secure networks.

Mechanical renovations included replacing twelve (12) existing air handling units with twelve (12) fully ducted, multi-zone, variable volume, 100% return air handling units. Outside air was decoupled from the 100% return air handling units using dedicated outside air systems with air-to-air energy recovery. Outside air was delivered directly to each space at space-neutral conditions. Dedicated outside air systems included total energy wheels, hot water preheat coils, chilled water cooling coils, and variable speed supply and exhaust fans. Variable volume air terminal units with heating hot water coils were provided for zone temperature control. Existing ductwork, hydronic piping, air terminal devices, hydronic pumps, and hydronic specialties were replaced with new. New direct digital controls were provided and integrated with the existing building automation system to remotely monitor and control mechanical systems, including tie-ins for a central base chiller plant and local backup chiller plant. Special consideration for phasing was provided during design to relocate and prevent disruption to the mission critical telecommunications ITN during construction.

The original electrical distribution consisting of two separate services (one at 480V and one at 208V) was replaced with a single new 480V service. A new service rated switchboard was provided to support the building distribution equipment and the local chiller plant. A 1,250kW standby generator was specified to serve the building emergency and optional standby power systems. A new high-efficiency LED lighting system with distributed, wireless, low-voltage lighting controls was also provided throughout the facility. All spaces received customized lighting control schedules to appropriately react to building occupancy and to maximize energy savings.
