Enduring Client Relationships

EDM’s corporate and commercial clients have come to expect high quality yet cost-effective engineering solutions from EDM; that is why so many return to EDM for their next project. We are known for our QA/QC management: we identify project risk factors, monitor progress, and verify results leading to project success.


Cambridge Innovation Center | St. Louis, MO

CIC St. Louis is housed in the Center for Emerging Technologies (CIC@CET) in the Cortex District. With Arcturis as Architect-of-Record, EDM provided all MEP engineering design services for the two-phase renovation of 49,610 SF of existing office spaces in the converted 1907 Dorris Motor Car Company buildings. Spaces include offices, private conference rooms, soundproof phone booths, storage, and a wet research laboratory. EDM’s services included white noise design and a SALTO system, access control platform combining electronic door components, peripherals and software. Completed photos courtesy of Arcturis


EDM Services: MEP/FP Engineering, Fire Protection Performance Review

Mercedes-Benz of St. Louis

The structural design of this 59,000 SF center creates dramatic spaces, integrating precise architectural design to accommodate the small site. Three walls feature floor to ceiling glass with no visible bracing, accomplished by cantilevering the roof diaphragm over the showroom from vertical bracing behind the showroom walls. The exposed steel roof framing creates a hi-tech ceiling and adds design value. Creative cast-in-place concrete solutions were developed for the service bays and exterior parking structure to provide a practical working facility for efficiency between operational activities.

EDM's design included an HVAC system with exposed ductwork that worked around full-height glass partitions. Lighting included pendant-mounted luminaires to work with exposed wood; linear, direct/indirect fixtures; accent walls illuminated by directional fixtures, and the lobby was furnished with custom T- and X-formed fixtures to tie into the T-Rex logo.
