WPAFB Sensors Lab

Wright-Patt Air Force Base sought contractors to renovate and add onto the Sensors Lab. The HVAC portion of the project was over $13 million.

  • MSD served as the Design Assist Contractor in conjunction with Heapy Engineering for this project. In collaborating with General Contractor, Butt Construction, MSD provided Design Assist solutions for the following:
    • A large, anechoic chamber
    • An outdoor range
    • Multiple, Class-100 clean rooms
    • A three-story office building addition with DCID 6-9 requirements on many of the rooms

WPAFB Chilled Water System

The chilled water system at a high-security building on the Air Force Base was undersized and unable to keep up with demand. The facility could not operate without chilled water due to the amount of information servers in the building, and the general nature of the building itself. The entire upgrade project would need to be completed with minimal shut down time at the building. HVAC portion of this project was over $3 million.

  • MSD worked in collaboration with Diaz Construction to complete the system upgrades on time and on budget with minimal shutdowns or disruption to the facility operations.

LJB, Inc.

LJB, Inc. was renovating their Miamisburg, OH office and wanted to incorporate energy-saving upgrades.

  • MSD provided Design Build services in tandem with Greensleeves Energy Solutions, a specialist in geothermal systems.
  • MSD and Greensleeves installed a new geothermal HVAC system with open and closed loops. In addition, MSD design and installed the plumbing portion of the renovation.
