EBL was contracted to provide the design services for a project consisting of two primary goals: The first was to implement the design of a complete HVAC systems upgrade for the 350,000 sf complex, the second was to design the necessary building modifications to accommodate the Air Force Office of Special Investigation (AFOSI). The HVAC upgrade included the construction of a completely separate Utilities Building located across the street houses a 1500 Ton chilled water plant and heating water generation plant utilizing the Base central steam system. The building systems included state-of-the-art DDC VAV reheat terminals and four-pipe fan coil systems as selected by the Department of the Air Force as well as a design of a new DDC Central Control and Monitoring System fully coordinated and compatible with the overall Base direct digital control Landis & Staefa energy management system.
Design for the AFOSI included an access card reader system for entrance into all AFOSI spaces, a $1,000,000 fully integrated LAN system connecting all of the workstations located throughout the complex and a security intrusion detection system to monitor the AFOSI spaces with special requirements for Sensitive Compartment Information Facilities. In addition, a new PBX telecommunications system, energy efficient lighting, ceiling systems and room finishes, lightning protection, 13.2 KV high voltage feeders, underground sprinkler and steam mains were also provided.
The fire protection engineering portion of the project included a life safety evaluation of the building, detailed field surveys of above-ceiling areas, hydrant waterflow testing, a ‘spec and hazard’ wet pipe system design, a dry pipe system for the unheated attic areas, new underground supply piping from the remote fire pump house to the existing building and a new addressable/multiplex voice fire alarm evacuation and detection system for the entire building.
In response to the owner’s request, EBL was asked to design a new standing seam metal roof on the entire building and redesign the front entry. The new pitched roof was installed over the existing flat roof that had been repeatedly penetrated for the addition of updated mechanical systems over the years. A new monumental entrance canopy was also part of the new rood, adding a landmark at the end of an important axis on the base.
