Cumming Group

Global Reach and Expanded Capabilities.

On October 7, 2025, Seneca Group merged with Cumming Group, the largest pure-play project management and cost consultancy in North America. The merger strengthened our ability to serve clients by combining our trusted development management and owner advisory expertise with Cumming Group’s global platform, specialized resources, and extensive project delivery capabilities.

Today, our clients benefit from the same leadership, culture, and client-focused approach that have defined Seneca Group for more than three decades, now backed by a global organization of more than 3,000 professionals across 70+ offices worldwide. Learn more about Cumming Group here.
