How Hotel Developers Validate a GC Number Before Committing Capital
A practical method for hotel developers and owner's representatives to check a general contractor's estimate against the drawings and their own costs before signing.
How Hotel Developers Validate a GC Number Before Committing Capital
Summary: A hotel developer has one chance to test the contractor's number, and it is before the contract is signed. The method is three checks: price the scope independently with your own historical unit prices, level every proposal you received against that scope line by line, and read the drawings for the risks that will become change orders. The stakes are the highest in commercial real estate. The median cost to develop a luxury hotel passed $1.6 million per room in the HVS U.S. Hotel Development Cost Survey 2026, and in the landmark study of 258 large infrastructure projects by Flyvbjerg, Holm and Buhl in the Journal of the American Planning Association in 2002, nine out of ten ran over their estimate, by 28 percent on average.
The problem with one number
A developer receives a design set from the architect and a proposal from the contractor. Between them sits the decision to commit capital. In most deals, the check on that proposal is one of three things: instinct, a second contractor's number, or a cost consultant's benchmark per key.
Each has a gap. Instinct does not scale across a pipeline. A second number tells you the two contractors disagree, not which one read the set correctly. A benchmark per key tells you whether the number is in range for the segment, not whether it covers what is in your drawings. None of them connect the number to the sheets.
Check one: price the scope with your own costs
The first check is to price the scope independently. Not a benchmark per key, but the scope of work in this set, by trade, priced with unit prices from your own completed projects.
This is where most developers stop short, because writing the scope from a 600 sheet hotel set is the work of weeks, and the owner's team is smaller than the contractor's. It is also the check that matters most. A line by line comparison shows which trades the contractor priced above your history, which below, and which are missing.
In Folio, Drawing Intelligence indexes the design set by sheet, discipline and CSI division and pulls the notes into one library. Scope Breakdown writes the scope of work by trade from the indexed set. Estimate prices each line with the unit prices you have entered from past projects, and marks any web lookup it used as a fallback. The result is your number, built from the same set the contractor priced, ready to compare.
Check two: level the proposals against the scope
The second check is to level every proposal you received against the same scope. Not proposal against proposal, which only shows where the contractors differ, but each proposal against the scope lines in the set.
Leveled this way, two things appear. Scope that one contractor carried and another excluded, which explains the price gap. And scope that no proposal carried, which is the change order waiting to happen.
Bid Leveling in Folio builds the packages from the scope, parses the proposals you upload, and lays them out on one grid against the scope lines. Developers use it to level general contractor proposals and, where the owner is buying trades directly, trade proposals.
Check three: read the drawings for risk
The third check is the one most often skipped. The risks that become change orders are visible in the set: a detail that conflicts with the plan, a note that shifts a scope item to the contractor's side of the boundary, a finish specified on a schedule that no proposal priced, a sheet that does not match its revision.
On a luxury hotel, the owner furnished boundary deserves its own pass. Furniture, fixtures and equipment and operating supplies are usually owner furnished, and where the contractor scope ends is written into the interiors package. HVS also notes in its 2026 survey that luxury projects increasingly carry a residential component, which brings a second set of finish levels and warranty expectations into the same drawings.
Risk Review in Folio reads the indexed set and writes a risk register with each item linked to the sheet it came from. Open the sheet from the register and judge the risk yourself before it is priced into a contingency or left out of the contract.
What this looks like in a pipeline
A developer running several hotel deals keeps each one in Pipeline, with the stage updating as the design set, the scope and the proposals come in. The three checks happen on every deal, from the same record, before the investment committee sees a number.
What Folio does not do is the work after signing. It does not review pay applications, track the budget or manage change orders. It focuses on the steps before a contract exists, where the number is still negotiable.
Before you commit
Price the scope with your own costs. Level the proposals against it. Read the drawings for the risks. A number that survives all three is one you can take to committee.

Frequently asked questions
How does a hotel developer know if a GC's number is right?
By pricing the same scope independently with their own historical unit prices, leveling the proposals received against that scope line by line, and reading the drawings for the risks that will become change orders. A number that survives all three is one you can commit to.
What is the most common reason hotel budgets blow up after signing?
Scope that was in the drawings but not in the number, most often at the boundary between contractor scope and owner furnished items, and in the interiors and food and beverage packages where the specification lives in notes rather than plans.
Can Folio review pay applications or track the budget during construction?
No. Folio focuses on the steps before a contract exists: indexing the design set, pricing the scope with your own unit prices, leveling proposals and building a risk register from the drawings.
