What JJA does

JJA, Inc. is a Dallas-based mechanical and electrical (MEP) engineering consulting firm founded in 1978 by Jim Johnston as James Johnston & Associates Inc., now operating under the JJA brand. The firm delivers professional engineering design services across HVAC, plumbing, fire suppression, electrical distribution, critical power systems, lighting, life safety, sustainable design, energy modeling, and MEP system commissioning. JJA holds Professional Engineering registrations in over 30 U.S. states and provides services locally in the Dallas-Fort Worth Metroplex as well as nationally through on-call MEP engagements with select corporate clients.

The firm operates as a vertical specialist across nine primary market sectors: mission critical facilities (including Tier 1-4 data centers, 911/command/network control centers, and financial trading environments), office buildings, corporate interiors and tenant development, industrial/manufacturing, adaptive reuse, hospitality/residential, religious facilities, automotive dealerships, and commissioning services. Technical capabilities include Building Information Modeling (BIM) production, electrical power studies such as arc flash and coordination analysis, underfloor air distribution, thermal storage systems, life cycle cost analysis, facility assessments, value engineering, and EV charger infrastructure design. The firm employs approximately 30+ team members across project managers, mechanical, electrical, and plumbing engineers, designers, CAD technicians, and administrative staff, led by President George Laity and Director of Engineering Jordan Jackson.

JJA generates revenue through project-based professional engineering consulting fees, billed on a quote basis determined by project scope and complexity, with reliance on repeat design opportunities from a core group of select enterprise clients. The go-to-market is sales-led and relationship-driven, with marketing conducted primarily through its project portfolio website and direct professional relationships with architects, developer/owner groups, and corporate clients. The firm is privately held with no disclosed institutional investors, parent company, or external funding history.
