CM-at-Risk vs. Design-Bid-Build: Choosing the Right Delivery Method for an Institutional Restoration Project
Every institutional building owner eventually asks the same question before a restoration project breaks ground: who should be at the table while the design gets finalized, and when should the contractor's price become real? The answer is a project delivery method, and on a restoration job the choice carries more weight than it does on new construction. Unknowns are the rule, not the exception, once crews open a historic wall, and the delivery method you pick determines how quickly — and how fairly — those unknowns get priced and resolved.
Two Ways to Build: What CM-at-Risk and Design-Bid-Build Actually Mean
Design-bid-build is the traditional sequence: the owner hires an architect to finish a complete design, puts the finished drawings out to competitive bid, and selects a general contractor based largely on price. The contractor has no input into the design before bidding and carries the risk of pricing a building it has not yet opened up.
Construction Manager at Risk (CM-at-Risk, often shortened to CMAR) brings the contractor on board early, alongside the architect, while the design is still being developed. The CM contributes constructability input and cost estimating throughout design, then commits to a guaranteed maximum price (GMP) before construction starts — taking on the risk of cost overruns above that number in exchange for a seat at the table from day one.
Why Delivery Method Matters More on a Restoration Project Than New Construction
On new construction, the building doesn't exist yet, so the design team is working from a mostly blank slate and the risk of surprise conditions is relatively low. Restoration and adaptive reuse work is different. Original drawings are often incomplete or missing entirely. Structural systems were modified by renovations nobody documented. Hazardous materials turn up behind plaster that looked fine from the hallway. On our Hillsdale City Hall restoration, conditions behind the original masonry only became clear once selective demolition started — exactly the kind of discovery that a design-bid-build contract, priced against incomplete drawings, struggles to absorb without a change-order fight.
That gap between what the drawings show and what the building actually contains is where delivery method stops being a procurement technicality and starts shaping the project's cost, schedule, and the working relationship between owner, architect, and contractor for the life of the job.
When Design-Bid-Build Still Makes Sense
Design-bid-build isn't obsolete, and institutional boards shouldn't assume CM-at-Risk is automatically the safer choice. When the building's existing conditions are well documented, the scope is narrow and clearly defined, and the owner's procurement rules require low-bid competitive award, design-bid-build delivers a clean, auditable process. It works well for straightforward facade repairs, code-driven system replacements, or any scope where the architect can fully resolve the design without field verification from a contractor's crew.
The tradeoff is that the owner is relying entirely on the completeness of the drawings. If a restoration scope is more complex than it first appears, design-bid-build pushes that risk onto change orders negotiated under schedule pressure — rarely the owner's strongest negotiating position.
When CM-at-Risk Earns Its Fee on a Complex Restoration
CM-at-Risk justifies its fee on projects where the unknowns are significant: a vacant historic building with no reliable as-built drawings, a structure that has to stay partially occupied during the work, or a scope where sequencing and phasing decisions made early in design change the final cost materially. Having a contractor's estimating and field expertise involved before the GMP is set means surprises get priced collaboratively, with the full design team in the room, instead of becoming adversarial change-order negotiations mid-construction.
Institutional work that has to keep operating through construction is the clearest case. On a project like our hospital restoration work, phasing decisions had to account for infection control, life-safety egress, and active clinical operations — all things a CM-at-Risk team can pressure-test against the budget during design, rather than discovering the cost impact after the GMP is locked.
Making the Call: Questions Institutional Boards Should Ask Before They Choose
Before an institutional board commits to a delivery method, it's worth asking a few direct questions. How reliable are the existing drawings and conditions assessments for this building? Does the project need to be phased around continued occupancy or operations? Does the procurement policy governing this project allow for a negotiated CM-at-Risk award, or does it require low-bid competition? And how much schedule and budget certainty does the board actually need going into design, versus how much flexibility it can tolerate if conditions change?
There's no universally correct answer — our work on the Canham restoration and the broader portfolio under our historic restoration practice have used both delivery methods, matched to what each building and each institution's procurement rules actually required. The method is a tool, not a philosophy, and the right choice depends on the building in front of you.
