Vandenberg Air Force Base Launch Facility Conditioned Power 

Customer U.S. Army Corps of Engineers
Location Vandenberg Air Force Base, California
Completed March 2016
Contract $5,971,110
Markets Federal Government, Defense

Five modules, each containing an integrated power assembly (IPA), were constructed to provide conditioned power from the electrical generation source at Vandenberg AFB to the remote location of the ballistic missile defense launch facility. Each IPA is housed in an anti-ballistic concrete masonry unit (CMU) enclosure and houses an uninterruptible power supply (UPS) to ensure power is provided to the site without interruption.

One key to successful project completion was effective collaboration with multiple stakeholders in disparate geographic locations and time zones. During the IPA design and submittal preparation phase, ABL hosted a virtual walk-through of the IPAs to allow stakeholders a 3D view of both the unit and the electrical systems layout inside. This innovative approach saved significant travel costs and expedited the design and review process by more than 30 days.

The project site presented many challenges. The remote location had no water or power, requiring concrete to be imported rather than prepared on site. The IPAs were constructed on a hillside, requiring extensive survey, earthwork and careful layout to ensure a stable and flat condition for the slabs and enclosures. In addition, concrete swales and other measures were implemented to control erosion. The highly corrosive marine environment dictated that all equipment had to be marine-grade stainless steel and that all workmanship be conducted in a manner to prevent corrosion.

Because of the facility’s role in protecting national security, an escort with secret security clearance was required to be present at all times. Although work was often halted to accommodate mission requirements, ABL was able to keep the work progressing and avoid schedule impacts from mission delays by relocating to different areas or performing other activities. Experience on mission-sensitive projects has enabled ABL to develop approaches to accommodate flexibility when stop work orders are issued.
