Mosites Construction

What Mosites Construction does

Mosites Construction Company is a third-generation, family-owned general contractor and construction manager headquartered in Pittsburgh, Pennsylvania, founded in 1959 by Steven T. Mosites. The company provides an integrated portfolio of construction delivery services — Preconstruction Services, Construction Management, General Contracting, and Design/Build — supported by specialized capabilities in Heavy Highway/Infrastructure, Prefabrication, Self-Perform Work, Sustainability (LEED and Passive House), Safety (Safety Beyond Zero program), and an integrated Warehouse & Logistics facility with a 15-acre equipment yard and 30,000 sq. ft. mockup and laydown space. Its operations span Western Pennsylvania, Ohio, and West Virginia.

The company serves institutional, public-sector, and private clients across multiple market verticals: Healthcare (e.g., WVU Medicine, Allegheny Health Network), Education (e.g., Carnegie Mellon University, Chatham University, Washington & Jefferson College), Heavy Highway/Infrastructure (e.g., PennDOT, Pennsylvania Turnpike Commission, Pittsburgh Regional Transit), Commercial/Office, Industrial, Housing, Liturgical, and Community/Non-Profit. Notable project credentials include the CMU Robotics Innovation Center (150,000 SF, LEED Platinum), the Greenfield Bridge Reconstruction (2017 ABCD Outstanding New Major Bridge), the Roberto Clemente Bridge Rehabilitation (2023 ASCE Civil Engineering Achievement Award), and the Armstrong Tunnel (2025 Road and Bridge Safety Improvement Award).

Mosites generates revenue through project-based contracts — competitive bidding for public-sector work and negotiated contracts for private-sector engagements — under traditional one-time project delivery and construction management fee structures. Pricing is project-specific and not publicly disclosed. Adjacent revenue streams flow through Mosites Development Company (founded 1969), which manages a 2M+ sq. ft. real estate portfolio, and MDC Brokerage, a commercial real estate brokerage subsidiary. The company is privately held with ownership and board composition entirely within the Mosites family, led by Board Chair and Building Division President M. Dean Mosites and Heavy Highway Division President Brian J. Gilkey.

Broad incumbents

• Barton Malow Company:
• Turner Construction Company: One of the largest general contractors in the U.S., serving healthcare, education, commercial, and infrastructure markets with integrated delivery. Comparable to Mosites on core services (CM, design/build, general contracting) and target verticals, but operates nationally with vastly greater scale, self-perform depth, and bonding capacity.
• Whiting-Turner Contracting Company: Privately held national GC with strong Mid-Atlantic presence serving healthcare, education, commercial, and infrastructure clients. Comparable in service mix and target verticals but operates at substantially greater scale and geographic breadth than Mosites.

Direct peers

• Gilbane Building Company: Private, family-influenced national GC with deep healthcare, education, and public-sector practices offering construction management, design/build, and general contracting. Highly comparable on delivery model, vertical mix (especially healthcare and higher education), and culture emphasis — and a direct competitor for Mosites' anchor institutional clients.
• Rycon Construction: Pittsburgh-based general contractor delivering commercial, healthcare, education, and multi-family projects across Pennsylvania and the Mid-Atlantic. Comparable on regional scope, target verticals, and self-perform capabilities; competes directly for CMU, UPMC, and private developer work.
• Massaro Construction Group: Pittsburgh-based, family-influenced general contractor specializing in healthcare, higher education, and corporate office construction management and design/build. Closely comparable on ownership profile, regional focus, institutional-client emphasis, and project delivery model — competes head-to-head for UPMC, university, and private clients in Western PA.
• Mascaro Construction Company: Pittsburgh-based, family-owned general contractor delivering healthcare, education, commercial, and heavy civil work across the tri-state region. The most direct local competitor, with overlapping service lines (CM, design/build, self-perform) and competing for the same CMU, UPMC, PennDOT, and municipal project pipelines.
• P.J. Dick Incorporated: Pittsburgh-based general contractor and construction manager serving commercial, healthcare, education, and heavy-highway/infrastructure markets with self-perform concrete and heavy-civil capabilities. Direct overlap with Mosites on both building and heavy-highway divisions in the same tri-state geography.
