Spencer Engineers, Inc. is the AE of record and/or Gerald R. Spencer, P.E. is the Mechanical and Electrical Engineer of Record for the following 48 U. S. AIR FORCE construction projects:

1.    New Joint Intelligence Systems Integration Facility - Lackland AFB, Texas - Spencer Engineers, Inc. (SEI) is the AE of record for the New Lackland AFB, TX Joint Intelligence Systems Integration Facility in 2001. Gerald R. Spencer, P.E., facilitated the CHARRETTE design conference to evaluate and re-affirm the design criteria, to create a concept plan, to coordinate all of the conflicting mission, personal and institutional into one agreed upon design plus get approval of the (conceptual) plan from all of the concerned parties. Gerald Spencer, P.E., was the project director and also the mechanical and electrical designer for the mechanical and electrical infrastructure systems. Mr. Carl Talbot, AIA, Mr. Jim Dunaway, AIA and Mr. William A. Davis, RA, P.E. prepared the architectural contract drawings. Mr. W. Paul Jones, AIA was the specifications writer and hardware specialist for the architectural building items. Mr. John L. Elam performed the Civil Design and the Structural Design.  The proposed facility consists of a 8,000 sf building housing two highly technical areas and support areas. There is an office - laboratory area with raised computer floor for data transmission media wiring and power connections. There is an air conditioned high bay storage warehouse with positive temperature and humidity control to store temperature and humidity sensitive data processing hardware and equipment.  SEI designed this building with walls insulated to comply with the SCIF construction requirements for sound attenuation. This project was within a secure fenced area so that physical protection was provides by a security fence that enclosed this new site. This facility was constructed in an un-secure area and the security fence was relocated after construction to enclose this facility into the secure area.  The foundation design was a fully supported structure above grade, and the floor between grade beams was slab-on-grade placed on top of 4 feet of select fill. Foundation piers were 45 feet deep. This project had raised computer flooring in the communications areas, secure grounding, separate secure power, separate unsecure power, electronic equipment repair/assembly laboratory, high bay equipment storage, restrooms, break room, and exterior security lighting.  This project has masonry front walls and some windows that meet SCIF attenuation requirements. The facility is fully air conditioned. LCCA indicated that electric heating was justified since the building was so well insulated, and the ventilation requirement was so low. The HVAC systems consist of separate DX, split air conditioning heat pump systems and electrical resistance re-heat heating systems for positive humidity control. A separate system will supply each controlled-conditioned zone with separate heating, humidity control, and cooling as required to maintain room temperature. The majority of the HVAC requirement is internal load (people, computer, lighting). The building envelope is well insulated to a "U" value of 0.030 average. The building will has a pre-treated outside air system that will provide absolute control of the maximum relative humidity in the building except when the exterior doors are open for extended lengths of time. There will not be any handicapped personnel at this facility, but the restrooms will be designed in accordance with the ADA handicapped accessibility requirements for possible future needs. It is less expensive now to construct the restrooms for the handicapped now as compared to modifying (tearing down and re-constructing) the restrooms at a later date. Handicapped visitors are sometimes guests or awardees at change of command and/or award ceremonies.  System complies with the NFPA 13 in accordance with the requirements of NFPA 13-1996 for an Extra Hazard Group 1 occupancy.
