McNary Bergeron & Johannesen

What McNary Bergeron & Johannesen does

McNary Bergeron & Johannesen (MBJ) is a privately held U.S. structural engineering consultancy founded in 2003 that specializes in construction engineering for complex bridge projects. The firm employs a proprietary "Engineered Construction®" methodology that integrates constructibility analysis, shop drawings, geometry control, erection manuals, and on-site technical support to bridge the gap between design intent and safe, efficient field execution. Its core technical capabilities span segmental concrete (balanced cantilever and span-by-span), cable-stayed, arch, and precast/post-tensioned bridge systems, with documented heavy-lift work including 400+ ton arch segments and 2,400-ton precast girders, custom launching gantry engineering (DEAL LG systems up to 3,600 tons), and novel methods such as arch roll-in construction.

MBJ operates a horizontal, project-based business model selling professional services — Construction Engineering, Design Engineering, and Pre-Bid Engineering — directly to general contractors, state and provincial departments of transportation, design firms, and select private developers. Engagements are contracted on a per-project basis through competitive bidding or direct negotiation across Design-Bid-Build, Design-Build, CM/GC, and P3 delivery methods, with no public pricing or rate cards. The firm maintains offices in Colorado (Denver), Connecticut (Hartford, Old Saybrook), and Florida, and reports a project portfolio of 175+ complex bridges delivered across four continents spanning 22+ years, including marquee projects such as the Frederick Douglass Memorial Bridge, Gordie Howe International Bridge, Manhattan West Platform, and I-59/20 Birmingham viaduct.

The go-to-market is enterprise field sales driven by technical reputation, industry publication authorship (ASPIRE, ENR, PTI Journal), and repeat engagement with general contractors on pre-bid and design-build pursuits. MBJ sustains a core technical alliance with Rizzani de Eccher USA and its DEAL equipment subsidiary, participates in the Bridges to Prosperity humanitarian program, and has accumulated multiple industry awards (ASBI, PTI, ENR, NSBA) from 2009 through 2024. Revenue, headcount, and ownership structure are not publicly disclosed.

Broad incumbents

• Arup: Global engineering consultancy with a renowned bridge and structural engineering practice. Comparable on complex bridge construction engineering (segmental, cable-stayed) while offering much broader multidisciplinary services.
• WSP: Global engineering consultancy with a significant bridge and structural engineering practice. Competes with MBJ on complex bridge design and construction engineering while operating across transportation, environment, and property sectors.
• AECOM: Global infrastructure consulting firm with a large bridge and structures practice. Competes with MBJ on complex bridge design-build programs, but operates at much greater scale across all major infrastructure verticals.
• Stantec: International engineering, architecture, and consulting firm with a notable bridge and structures practice. Comparable to MBJ on bridge construction engineering work while serving broader infrastructure and environmental markets.
• HNTB Corporation: Major US infrastructure engineering firm with a leading bridge and structures practice. Competes with MBJ on state DOT bridge design and construction engineering projects, though HNTB operates across a much wider transportation portfolio.
• Parsons Corporation: Large engineering and infrastructure services firm competing for complex bridge and transportation projects, including design-build and P3 deliveries similar to MBJ's core work.
• HDR Inc. Large multi-disciplinary engineering firm with a substantial bridge practice that competes for the same DOT and design-build bridge work as MBJ, but as part of a broader water, transportation, and building portfolio.
• Jacobs Solutions: Global engineering and consulting firm with a substantial transportation and bridge practice. Competes with MBJ on complex infrastructure projects while delivering a far broader range of services.

Direct peers

• Modjeski and Masters: Long-standing specialist in bridge design, construction engineering, and inspection. Comparable to MBJ in project types served (complex movable, long-span, segmental bridges) and segmental/extradosed expertise.
• T.Y. Lin International: Global engineering firm specializing in bridge design and construction engineering. Closely comparable to MBJ in technical scope (segmental, cable-stayed, arch bridges) and customer base (DOTs and contractors), with a larger international footprint.
