Construction Manager at Risk (CMAR)

Services

CMAR Experience

Construction Manager at Risk (CMAR) is a collaborative project delivery method that brings the contractor on board early to support both design and construction. Under a CMAR approach, Greystone works alongside the owner and design team during preconstruction to provide budgeting, constructability reviews, scheduling, and cost-saving recommendations. Once design progresses, the project is delivered under a Guaranteed Maximum Price (GMP), transferring cost and performance risk to the construction manager.

This method promotes transparency, early problem-solving, and informed decision-making — helping owners maintain control over scope, schedule, and budget while benefiting from contractor expertise throughout the process. CMAR is especially well-suited for municipal and public projects where accountability, collaboration, and predictable outcomes are critical.

The CMAR Process

  1. Early Engagement & Planning
    We join the project during design to understand goals, constraints, and funding requirements while establishing a clear path forward.

  2. Preconstruction & Cost Modeling
    Our team provides detailed budgets, constructability reviews, and value options to align scope with schedule and budget.

  3. Collaborative Design Support
    We work closely with the owner and design team to refine documents, reduce risk, and identify efficiencies before construction begins.

  4. Guaranteed Maximum Price (GMP)
    Once design reaches the appropriate milestone, we establish a GMP that provides cost certainty and shared accountability.

  5. Construction & Closeout
    Greystone manages construction, safety, quality, and coordination through completion, delivering a facility ready to serve the community.
