Engineering Consultants

What Engineering Consultants does

Engineering Consultants, Inc. (ECI) is a privately held mechanical, electrical, and plumbing (MEP) engineering services firm founded in 1976 in Boise, Idaho by Leslie (Les) Stith. The firm delivers integrated building systems design across mechanical, electrical, plumbing, and Building Information Modeling (BIM) coordination disciplines, serving commercial, industrial, education, civic/community, and multifamily construction projects nationwide. Named engagements span national retail brands (Les Schwab, Safeway, PetSmart, Fred Meyer, Albertsons, Bish's RV, D&B Supply), industrial operators (Jackson Foods, Hayden Beverage, Zoroco, Micron Building 17/17C), higher education (Boise State University, Gem Prep School, Fruitland Charter School), and public-sector institutions (Idaho National Guard, Boise Rescue Mission, Valley Regional Transit). The firm operates from a single Boise headquarters with no disclosed satellite offices.

The technical platform is built on Autodesk Revit and AutoCAD for multi-discipline modeling, with Autodesk BIM360 used for project collaboration and model set-up, and BIM coordination delivered across LOD 200-500 levels. An in-house BIM Manager oversees cross-discipline coordination to identify and resolve design conflicts before construction, supported by an internal quality-control process targeting fewer change orders. A separate in-house design-build team produces bid-quality engineering documents for design-build contractors, complementing the standard design-bid-build delivery.

ECI runs a project-based, relationship-driven commercial model. Engagements are scoped and quoted per project with no published price list, initiated through a website contact form, direct phone, email, and LinkedIn outreach. Professional engineers hold mechanical and electrical PE licenses across many U.S. states, with new licenses acquired as project locations demand, enabling nationwide delivery. The firm is founder/management-owned with no disclosed institutional investors, parent company, or M&A activity, and is led day-to-day by President Cathy Miller, PE, with founder Les Stith serving as Chairman.

Core offering

Engineering Consultants (ECI) provides Mechanical, Electrical, and Plumbing (MEP) engineering design and Building Information Modeling (BIM) coordination services for commercial, industrial, education, civic/community, multifamily, and healthcare construction projects in the United States. The firm bundles the three MEP disciplines into a single-source design engagement, supported by an in-house design-build team and pre-construction BIM coordination. Projects are staffed by PE-licensed engineers, EITs, BIM modelers, and drafters operating from Boise, Idaho, with PE licensure in multiple states enabling nationwide delivery.

Product overview

Engineering Consultants (ECI) delivers its offering as a unified MEP engineering services practice rather than a packaged software platform, anchored by three core disciplines — Mechanical, Electrical, and Plumbing engineering — that are typically engaged together on each project. Layered on top of these core services is Building Information Modeling (BIM) Coordination, which functions as an embedded specialty offering (including an in-house design-build team) used to resolve cross-discipline conflicts before construction. These services are then applied across six market-segment project types: Commercial, Industrial, Education, Civic & Community, Multifamily, and standalone BIM engagements, each represented as a dedicated section of the firm's project portfolio.
