CONSOR Engineers

Consor Engineers is a North American infrastructure engineering and construction management firm chaired by Dr.

CONSOR Engineers

CONSOR Engineers was formed when four regional consultant leaders joined forces, then absorbed several other firms to expand its geographic footprint and service offerings. The firm is chaired by Dr. Hisham Mahmoud, a New Mountain Senior Advisor whose career includes building and transforming infrastructure companies. Its wealth origin is not publicly disclosed — the firm appears to be an operating company rather than a traditional family office asset pool. The firm provides advisory, planning, design, structural assessment, and construction management for water and transportation infrastructure. It has confirmed positions on public-sector projects including the Steigerwald Floodplain Restoration Project (a $23M floodplain reconnection), the Eglinton Crosstown West Extension (a 9.2-kilometer light rail transit extension), and the Bridge Street Bridge rehabilitation. Geographic footprint spans the United States and Canada, with offices in 24 US states and Ontario. Operating as a portfolio company means its deployment is driven by government contracts, not private equity deals. Total team size and AUM are undisclosed. The leadership team includes Patrick Cassity, who previously led the Global Roads and Highways division of Parsons Corporation. In May 2024, the firm acquired Cavnue, a smart road technology company bringing AI-enabled digital twin capabilities for highway operations (per the firm, May 2024). No philanthropic foundation or alternative investment vehicle is publicly linked. The firm's structural differentiator is its roll-up model: management merged over a dozen regional engineering firms into a single platform, retaining local brand relationships while achieving national scale. This allows it to bid on large public projects while maintaining the local knowledge public agencies require. Its governance relies on a chairman who oversees multiple infrastructure-sector portfolio companies, creating cross-portfolio expertise.

Frequently asked questions

Who runs investment decisions at Consor Engineers?

The firm is chaired by Dr. Hisham Mahmoud, a New Mountain Senior Advisor with over 36 years in infrastructure services. Patrick Cassity, who previously led global roads and highways at Parsons Corporation, is a member of the leadership team. The day-to-day engineering operations are managed by a team of licensed professional engineers.

How does Consor Engineers source its projects?

Consor relies on a network of local offices across the United States and Canada that maintain longstanding relationships with public agencies. The firm wins design and construction management contracts through competitive bidding and direct government procurement, not private equity deal sourcing.

Is Consor Engineers structured as a single family office or an operating company?

Consor Engineers functions as an operating company — an engineering and construction management firm — rather than a traditional family office that manages investment assets for a single wealthy family. It appears to be a portfolio company held by an investment firm.

What investment stages does Consor Engineers typically target?

Consor Engineers does not operate as an investment firm. Its activities involve bidding on and executing infrastructure projects for government clients at various stages — from initial planning and design through construction management — rather than investing in companies.

Does Consor Engineers maintain any philanthropic structures?

The firm's website describes community engagement such as food bank support, STEM education outreach, and river cleanups, but no separate charitable foundation is publicly disclosed.
