What CJD does

CJD Engineering, LLC is a Missouri-based consulting engineering firm founded in 2005 that specializes in Mechanical, Electrical, and Plumbing (MEP) systems design, testing, and commissioning for commercial, institutional, and industrial buildings. The firm operates four core service lines — Mechanical Engineering, Electrical Engineering, Commissioning and Energy Services, and NEBB-certified Testing, Adjusting, and Balancing (TAB) — and supplements these with add-on services including BIM modeling, building code review, due diligence assessments, LEED design and documentation, and energy auditing. CJD holds NEBB TAB certification, AABC Commissioning Group (ACG) Commissioning Authority (CxA) certification, and professional engineering licenses across 47 states, enabling multi-jurisdictional service delivery.

The firm serves healthcare providers (Mercy Hospital Cassville, Mercy Springfield OR HVAC renovations), K-12 and higher education clients (Weber Elementary, Neosho Junior High, Boyd Elementary, Joplin Public Library), government and military entities (Missouri National Guard AVCRAD and TASMG projects), and hospitality/recreation developers (Caesars Republic Scottsdale, Hilton at Cavasson, Delta by Marriott, Embassy Suites Jonesboro, the Betty & Bobby Allison Sports Town Complex). Project scales cited in CJD's portfolio range from 21,000 sq ft municipal facilities to a 260,000 sq ft, $125 million hotel, with engineered outcomes including the first arena in the United States to achieve LEED Gold Certification (O'Reilly Family Event Center).

CJD generates revenue through project-based professional service fees earned on engineering design, commissioning authority, and TAB contracts, with pricing determined per engagement rather than publicly disclosed. The firm employs a team of 26 professionals across two Missouri offices (Springfield headquarters and Creve Coeur/St. Louis regional office), and operates a direct, relationship-driven go-to-market targeting facility owners, developers, government agencies, and institutional clients across its licensed states.
