What Tunstall Engineering Group does

Tunstall Engineering Group (TEG) is a privately held structural and geotechnical engineering services firm based in Cranberry Township, Pennsylvania. Founded in 2014, the firm specializes in complex bridge and transportation infrastructure projects, serving primarily contractors and government agencies through project-based consulting engagements concentrated in Pennsylvania and the surrounding region. The company's service portfolio covers steel and concrete girder erection engineering, bridge demolition planning, bridge jacking, support of excavation, truss bridge rehabilitation, full-service bridge design, geotechnical engineering, accelerated bridge construction (ABC), and design-build / alternate design prime consulting.

TEG's technical foundation rests on 3D finite element analysis (FEA) capabilities, which the firm applies to complex erection staging, member and gusset plate strengthening, and stability verification during construction. Documented project work includes the 15-span, 4,545-foot CSVT River Bridge over the Susquehanna River (with pier heights near 200 feet and spans up to 350 feet), the Andy Warhol (7th Street) Bridge rehabilitation in Pittsburgh, and an innovative lateral bridge slide installation on the Pennsylvania Turnpike. The firm emphasizes a multi-engineer quality-control review process on every deliverable and positions itself as a "link between engineering and construction" by combining design capability with field constructability expertise.

Commercially, TEG operates as a direct-to-client consultancy with a sales-led go-to-market motion, leveraging its website and a LinkedIn presence for top-of-funnel visibility. Revenue is generated through professional-services engagements quoted on a project-by-project basis, with no publicly disclosed pricing, no disclosed funding rounds, and no evidence of institutional or parent-company ownership. The firm is small (1–10 employees) and appears to operate largely on a core-engineer-plus-subcontractor model, given the scale of the projects it has executed relative to its stated headcount.

Direct peers

• Michael Baker International: National engineering consultancy with a strong bridge and transportation infrastructure practice serving state DOTs and contractors. Most directly comparable mid-sized firm in the bridge specialty engineering niche where TEG competes.
• Modjeski and Masters: Pure-play bridge engineering firm specializing in design, analysis, and rehabilitation of complex bridges including trusses and movable spans. Closely comparable in specialization, project profile, and technical depth to TEG's bridge focus.
• Hardesty & Hanover: Mid-sized bridge and movable bridge engineering consultancy serving DOTs and contractors across the U.S. Comparable niche positioning as a bridge-specialist firm, with similar project delivery and analysis capabilities.

Regional players

• Gannett Fleming: Pennsylvania-headquartered engineering firm with deep transportation and bridge practices serving the Mid-Atlantic. Comparable in regional footprint and DOT/contractor client mix, though larger and broader in scope than TEG.
• Pennoni Associates: Philadelphia-based engineering firm with structural, geotechnical, and transportation practices serving Pennsylvania and the Mid-Atlantic. Overlaps with TEG in regional client base and engineering service mix.

Broad incumbents

• HDR Engineering: Large national engineering consultancy with a substantial bridge and transportation infrastructure practice. Competes for the same DOT and design-build bridge pursuits as TEG but operates at much greater scale and scope.
• WSP USA: Global engineering firm with major bridge, geotechnical, and transportation infrastructure practices in the U.S. Competes with TEG on large bridge design-build projects while also offering broader program management services.
• AECOM: Global infrastructure consulting firm with large bridge and transportation divisions. Competes for major bridge pursuits and design-build contracts alongside smaller specialists like TEG.
• Jacobs Solutions: Global engineering and program management firm with major U.S. transportation and bridge practices. Competes for large DOT and design-build bridge programs where TEG may also pursue or sub-consult.
