The Cheapest Change Is the One Made on Paper
Every change order has a moment before it exists as a change order. It starts as a line on a drawing, a detail that assumes a condition the site does not actually have, or a sequence that looks fine in two dimensions and falls apart in the field. At that stage, fixing it costs an eraser and a few minutes. Once concrete is poured or steel is set, the same fix costs a demolition line item, a schedule delay, and a call to your equity partners. A constructability review is the discipline of finding that error while it still costs nothing.
For a developer underwriting a hotel deal on a target IRR, this is not a construction nicety. It is a capital protection step that happens before pricing, before subcontractor commitments, and long before the first mobilization. Constructability review construction practices exist specifically to separate the cost of a mistake on paper from the cost of the same mistake in the ground.
What the Review Actually Catches
A constructability review is not a rubber stamp on the architect’s set. It is a line-by-line interrogation of whether the design as drawn can be built in the sequence, budget, and site conditions assumed in the pro forma. Common findings include:
- Sequencing conflicts between structural, MEP, and finish trades that were never coordinated on the same timeline
- Site condition mismatches, where soil reports, easements, or utility locations do not match what the design assumed
- Long lead time exposure on materials or systems specified without confirming availability against the schedule
- Redundant or over-specified systems that add cost without adding value to the guest experience or the brand standard
- Code and permitting gaps that surface late and force redesign after pricing has already been locked
Each of these, caught early, is a redline. Caught after the general contractor has priced the set and subcontractors have committed, each becomes a formal change order with markup, schedule impact, and a renegotiation of terms that were supposed to be fixed. This is the same dynamic explored in why budget overruns start in design, and it is why the review has to happen before the number gets hard.
When to Run It
The value of a constructability review is almost entirely a function of timing. Run it at 100% construction documents and you are confirming what is already too expensive to change. Run it at schematic or design development, before the architect has locked details and before the general contractor has priced anything, and the same findings become simple revisions instead of negotiated costs.
This is also why bringing construction expertise into the process early, rather than after design is finished, changes the outcome. A general contractor engaged only to bid a finished set has no ability to flag a sequencing problem before it is baked into the drawings. One engaged earlier can. That principle is the core of why early GC involvement protects the capital stack, and the constructability review is the mechanism that makes it concrete instead of theoretical.
The review should happen before the drawings go out for competitive pricing. Once multiple general contractors are pricing a flawed set, you are not solving the design problem, you are watching it get baked into every bid you receive, including the low one that looks attractive until the scope gaps surface. That risk is detailed in why the lowest bid is a risk signal, and a clean constructability review is one of the few tools that prevents it before pricing even starts.
The Savings Math
The math on this is not subtle. Industry data on construction rework consistently shows that a change identified in design costs a fraction of the same change identified during construction, and a fraction of that again if it surfaces after the item is installed. On a mid-market hotel project, a single sequencing conflict discovered in the field, say a mechanical shaft that was never coordinated with structural framing, can cost weeks of schedule and tens of thousands of dollars in rework. The same conflict caught in a constructability review costs an hour of coordination between the structural and MEP drawings.
Multiply that across the dozen or so conflicts a thorough review typically surfaces on a ground-up hotel project, and the avoided cost routinely exceeds the fee for the review itself by a wide margin. But the larger number is not the direct cost avoidance. It is the schedule protection. Every week of field rework is a week of delayed opening, delayed revenue, and delayed debt service coverage. Schedule slippage compounds directly into IRR erosion, a relationship laid out in detail in the analysis of what a 90 day delay does to projected IRR. A constructability review is one of the lowest cost interventions available for protecting that timeline before it is ever at risk.
None of this requires optimism about how a project will go. It requires treating the design set the way an underwriter treats a pro forma: as a set of assumptions that need to be stress tested before capital is committed against them.
Protecting the Return Before the First Draw
A constructability review does not change the vision for the hotel. It changes what the pro forma assumes will happen when that vision meets a general contractor’s schedule and a subcontractor’s field crew. Catching the gap on paper, before pricing and before mobilization, is one of the more reliable ways to keep a project’s actual costs and actual schedule close to what was underwritten. If you want that discipline applied to your next project before pricing locks anything in, start with a pro forma and feasibility review.
