What Theorem Design Group does
Theorem Design Group is a privately held, Colorado-based civil and structural engineering firm founded in 2014 by three Principals (Matt Gilbert, Jeb Sloan, Caroline Draper) that provides full-service transportation design engineering exclusively to government clients within the state. The firm delivers six integrated service lines — Roadway Design (intersection/interchange design including DDI, SPUI, roundabouts, CFI; freeway reconstruction; urban and rural arterials), Structural Design (cast-in-place concrete bridges, prestressed girder bridges, steel plate girders, pedestrian and wildlife crossings, retaining walls), Drainage Design (hydrologic/hydraulic modeling, floodplain mapping, scour evaluations, MS4-compliant BMPs), Multi-modal Design (bike/pedestrian infrastructure, complete streets, ADA compliance), Owner's Representative Services (contract development, RFQ/RFP, ATC reviews, construction administration for design-build projects), and Asset Management (data-driven lifecycle planning for roads, bridges, signals, and transit). The firm's competitive position rests on deep knowledge of CDOT standards, local contractor practices, and Colorado's diverse geography, with a reference portfolio of nearly 100 bridges engineered within the state and Principals who bring dual contractor/owner-side perspective on design-build work.
The company operates as a founder-led, owner-operated professional services firm with no disclosed institutional investment or parent company. It generates revenue through project-based professional services contracts awarded via standard government procurement (RFQ/RFP, multi-year contracts), billing against scope and complexity of roadway, bridge, drainage, multi-modal, owner's representation, and asset management assignments. Its customer base spans Colorado state, county, and municipal transportation departments — most prominently the Colorado Department of Transportation (CDOT) on flagship projects including the SH 79 over I-70 Bridge Replacement, Region 2 Bridge Bundle (delivered approximately six months ahead of original construction schedule), and C470 Express Lanes, with additional municipal engagements for the City of Littleton and Town of Bennett. Distribution is entirely direct-engagement and principal-led, supported by a website portfolio and principal LinkedIn visibility rather than paid marketing.
The firm is actively hiring across drainage, structural, roadway, and project management roles, suggesting an organizational scale-up phase, while continuing to operate within the 1-10 employee band. Headquartered in Denver, Colorado, Theorem is positioned as a boutique, domain-specialized alternative to large national AEC firms for Colorado public-sector transportation work, with its moat built on local standards expertise and Principals' accumulated two-decade-plus relationships rather than scale or technology differentiation.
