In any construction project, timing is everything—not just in execution, but in decision-making. One of the most critical decisions a Project Owner faces is when to engage an external Construction Manager (CM). Should it be during the design and bidding stages, or only once construction begins? The answer has significant implications on cost, quality, and overall project success.
The Case for Early Engagement (Design & Bidding Stage)
Bringing a Construction Manager on board during the design phase is often considered a proactive and strategic approach. At this stage, the CM acts as a bridge between design intent and construction reality.
Key advantages include:
- Constructability Insights: A CM can review plans and identify potential issues before they become costly problems on-site.
- Cost Control: Early involvement allows for real-time cost estimating, helping the design team align with the project budget.
- Value Engineering: The CM can suggest alternative materials or methods that maintain quality while improving efficiency.
- Bid Package Clarity: During bidding, the CM ensures documents are clear, complete, and coordinated—reducing ambiguities that could lead to disputes or inflated bids.
In essence, early engagement transforms the CM into a strategic advisor, shaping the project before it takes physical form.
The Case for Later Engagement (Construction Stage)
Some Project Owners opt to engage a CM only once construction begins, often to oversee execution and manage contractors.
Benefits of this approach include:
- Focused Oversight: The CM concentrates on schedule tracking, quality control, and site coordination.
- Cost Savings (Upfront): Owners may perceive savings by deferring CM engagement until necessary.
- Defined Scope: With design already completed, the CM’s role is more execution-driven.
However, this approach is largely reactive. By the time construction starts, many decisions are already locked in. Any design flaws, coordination gaps, or budget misalignments are now harder—and more expensive—to correct.
The Risk of Late Involvement
Engaging a CM only during construction is similar to bringing in a problem-solver after problems have already formed. While a skilled CM can mitigate issues, they are often working within constraints that could have been avoided entirely.
Common consequences include:
- Design revisions during construction (leading to delays)
- Change orders due to incomplete or unclear bid documents
- Budget overruns caused by lack of early cost validation
Building a Ship vs. Steering It at Sea
Think of a construction project like building and sailing a ship.
Engaging a Construction Manager early is like having an experienced shipbuilder involved while the ship is still being designed. They ensure the vessel is seaworthy, balanced, and efficient before it ever touches water.
Waiting until construction begins is like hiring a captain only after the ship is already sailing. The captain can steer and manage the journey—but if the ship was poorly built, even the best navigation cannot fully prevent trouble.
Finding the Right Balance
While early engagement is generally more beneficial, the “right” timing can depend on project complexity, budget, and Owner priorities. For large or technically demanding projects, early CM involvement is almost always worth the investment. For simpler projects, later engagement may suffice—but with increased risk.
A hybrid approach is also possible: engaging the CM in a limited advisory role during design, then expanding their scope during construction.
The timing of engaging a Construction Manager is a strategic decision that shapes the trajectory of a project. Early involvement during design and bidding allows for better planning, cost control, and risk mitigation. Late involvement during construction focuses on execution but often limits the ability to influence outcomes.
Ultimately, engaging a CM early is not an added cost—it is an investment in foresight, efficiency, and project success.
