Planning and budgeting comparison

Make three bids answer the same question

Estimates rarely disagree about price; they disagree about the project. This comparison method aligns bids line by line, on scope, assumptions, quantities, products, allowances, permits, schedule, and exclusions, so the numbers finally describe the same work and the real differences stand out.

How to run the comparison

Build a simple grid with your scope lines as rows and each bidder as a column. Transfer every proposal into the grid rather than reading proposals side by side, because formats are designed to read well, not to compare well. Anything a proposal does not address gets an explicit blank, and blanks are findings, not gaps to skip.

Then reconcile before you judge. For every meaningful difference, ask the bidder why their line diverges: a different assumed condition, a different method, a different quality class, or something they saw that others missed. The reconciliation conversations are the real evaluation; the professional whose explanations are specific and checkable is showing you how they will run the project.

Where bids actually diverge

Scope interpretation is the largest source of spread. One bidder includes substrate replacement, another assumes the existing base is sound, a third excludes it and waits for demolition. None of the three is dishonest; they are pricing different risk positions. Your grid makes the positions visible so you can choose one deliberately and ask the others to match it.

Allowances are the second divergence engine. A low bid built on thin allowances is not cheaper; it is deferred. Convert every allowance to its assumed quality class and ask what the stated figure actually buys locally. Two proposals with identical totals can carry very different purchasing power at the tile counter.

Exclusions and schedule round out the picture. An excluded permit, an excluded haul-away, or a schedule that assumes instant selections each move real cost and time onto you invisibly. Read the smallest print in each proposal against the same checklist, and treat what is missing as information about how surprises will be handled later.

The alignment grid, line by line

Work each row across all bids before moving down. The order runs from largest divergence source to smallest.

Comparison rows and what to resolve in each before choosing.
TopicWhat to alignWhat a divergence usually means
Scope linesEvery demolition, trade, and finish item mapped to your written scope.Different assumed conditions or a bidder who read the room differently.
AllowancesEach allowance converted to the quality class it can really buy.A low total quietly built on selections you have not made yet.
QuantitiesTile areas, fixture counts, and glass dimensions stated, not implied.Measurement differences that will surface as change orders.
Permits and scheduleWho applies, what is covered, and what the calendar assumes.Administrative cost and time moving silently onto the homeowner.
ExclusionsEvery not-included line collected in one place across bids.The gaps where mid-project pricing will happen without competition.

Before you choose a bid

Run the finalists through these checks; the answers matter more than the totals.

Aligned

  • All bids priced against the same written scope revision

  • Allowances normalized to comparable quality classes

  • Blanks in the grid resolved with direct questions

Explained

  • Every large line difference has a bidder explanation you can verify

  • The lowest bid's savings have named sources, not vibes

  • Schedule assumptions about selections and lead times are realistic for you

Decided

  • Which risk positions you are accepting, in writing

  • What moves into the contract as fixed versus allowance

  • Which excluded items you will contract separately

Bring these questions to the conversation

  • Walk me through why your number differs here.

    Point at a specific grid line. Specific, checkable explanations mark an estimator you can work with; defensive generalities predict how change orders will go.

  • What condition are you assuming that others might not be?

    Surfaces the risk position directly. The best answer names the assumption and what happens to price if it proves wrong.

  • What does this allowance buy at your usual supplier?

    Converts an abstract figure into shelf reality. Ask it identically of every bidder and compare the products, not the numbers.

  • If I accept your bid, what is still undecided?

    A candid list of open selections and unpriced risks is the mark of an honest proposal; a claim that everything is covered is the mark of an optimistic one.

Common questions

Frequently asked questions

Should I just take the middle bid?

No. The middle of three differently-scoped projects is not a safer project, it is an unexamined one. Align the scopes first; often the right choice is the bid whose assumptions survive reconciliation, at whatever position it sits.

Is it fair to show one bidder another's price?

Sharing totals invites price-matching games. Sharing scope differences is fair and productive: asking a bidder to include the substrate work another bidder priced improves comparability without auctioning the project.
