Vaughn Construction served as the construction manager-at-risk for a new 9-1-1 Emergency Network facility. The project is a secure site consisting of a 2-story, 50,000 SF building, communications tower, and paved parking area. The facility functions as the organizational headquarters for Greater Harris County 9-1-1 Emergency Network, providing training, technology, and organizational support for the district’s emergency communications sites and a reliable Public Safety Answering Point (PSAP) back-up site for the district's agencies. The facility has multiple levels of redundancy in all systems and operates as an emergency operations system during disasters.
The complexity of systems within the facility combined with the function it serves makes it a “one of a kind” project. The levels of redundancy for electrical and HVAC systems within are second to none. In addition to redundancy on the back-up air cooled chillers, the facility can operate all HVAC equipment via use of a glycol chilling system. The electrical system redundancy is two times N+1. Back-up power for the electrical system is serviced by two 500-KVA generators and their associated paralleling switchgear. Another integral part of the electrical redundancy is a complete uninterruptible power supply (UPS) system, which ensures that no loss of power to the building occurs in the switch from normal power to generator power. This facility also includes state-of-the-art security and audio/visual systems, which maximize the functionality of the facility and aid GHC 9-1-1’s efforts to stay on the cutting edge of the latest technology. Over 250,000 feet of communication/data cabling was installed on the project to service the needs of GHC 9-1-1. These top-of-the-line systems ensure GHC 9-1-1 will continue to provide unparamounted emergency service to the citizens of Greater Harris County.
