Case Study: McCarthy achieves faster GMP alignment and stronger project transparency with Join

How McCarthy used Join to collaborate and build trust for The City Of Sioux Falls water reclamation plant project

McCarthy Building Companies, a major construction firm, was hired by the City of Sioux Falls as a Construction Manager at Risk for a critical water reclamation plant expansion. The challenge was achieving cost certainty on the technically complex project, as initial estimates came in $50 million over the owner's original budget. This required intense collaboration with the design team and the city to align on scope and value-engineer the project, a process made more difficult by pandemic-induced inflation and relying on traditional spreadsheet tools.

They implemented the Join decision-making platform to foster transparency and real-time collaboration between the owner, engineer, and contractor. Join provided a centralized hub for tracking costs, exploring budget reduction scenarios, and facilitating informed decision-making, which was crucial for the open-book CMAR delivery method. Using Join, McCarthy successfully guided the team to a Guaranteed Maximum Price, building trust through visibility into cost build-ups and saving significant time in meetings that were now focused on decisions instead of reconciling data.
