Pre-construction planning
An estimate is a prediction about conditions. The quality of the prediction is set almost entirely by how much you actually know about those conditions before you price them — and on finishing and envelope scopes, drawings alone never tell you enough.
What drawings reliably give you is geometry: areas, elevations, openings, assemblies as designed. What they do not give you is the state of what is already there. Existing substrate condition, previous coatings and their adhesion, moisture history, how square the building actually got built, what the last contractor left behind — none of that is on the sheet, and all of it moves the number.
So the pre-construction sequence that produces a defensible price looks like this:
- Read the documents for exclusions first. Before pricing anything, find what the tender documents push onto the trade — protection, cleanup, hoisting, access, temporary heat, off-hours restrictions. These are cost, and they hide in the general conditions rather than the trade section.
- Walk the site if it exists. On repair, renovation and repaint work this is not optional. A twenty-minute walk resolves questions that would otherwise be priced as contingency or discovered as a change order.
- Establish the substrate. What is being finished, what condition it is in, and what preparation it will genuinely need — not the preparation the specification assumes.
- Confirm access and sequence. How the crew reaches the work, what equipment that requires, whether the building is occupied, and what has to be finished by others before the scope can start.
- Write down the assumptions. Every unknown that survives to pricing becomes a stated assumption in the quote, not a silent risk inside the number.
The rule that saves the most money
If you cannot verify a condition, do not bury it in contingency — state it as an assumption. A quote that says “priced on the basis that existing coating is sound and requires spot priming only” converts an invisible risk into a visible, negotiable line. If the assumption is wrong, the conversation happens before the work, not after the invoice.
Writing the scope document
The scope document is the single most underrated deliverable in trade contracting. It costs an hour and it prevents the argument that costs weeks.
A quote answers how much. A scope answers for what — and when those two live in the same paragraph, the second one always loses. Separate them. The number goes on one line; the scope gets its own section, and it says four things:
What a scope must state
- Inclusions — the specific operations, surfaces and quantities covered
- Exclusions — named explicitly, not implied by absence
- Assumptions — the conditions the price depends on
- Products and standards — system, finish level, number of coats
What sinks a scope
- “As per plans and specs” with no further detail
- Exclusions left unwritten because they seem obvious
- Finish level unstated — the most common drywall dispute there is
- Quantities with no unit, so nothing can be re-measured
- A price that silently absorbs an unconfirmed condition
Exclusions are where the discipline actually shows. Nobody enjoys writing them, everyone reads them, and every one that goes unwritten will eventually be argued as included. If the scope does not cover moving furniture, patching after other trades, colour changes past the specified count, or the second mobilization caused by someone else’s delay, then the document has to say so.
Finish level deserves its own line every single time. “Drywall taped and painted” is not a scope — the gap between a Level 3 and a true Level 5 skim coat is enormous in labour, and the two look nothing alike under critical lighting. Naming the level in writing is the difference between a priced expectation and a disagreement waiting for a sunny afternoon.
Unit pricing that scales
A lump sum tells the client one thing: the total. A unit-priced estimate tells them how the total was reached, which is what makes it defensible when quantities move — and on renovation and multi-unit work, quantities always move.
Building an estimate from unit rates rather than from a feeling has three practical consequences:
01
Changes get priced instead of argued. When an established rate per unit already exists in the contract, adding six more units is arithmetic. Without one, every change becomes a fresh negotiation conducted under schedule pressure — the worst possible conditions for the trade.
02
The estimate becomes reviewable. A reviewer can check quantity and rate separately. That is how a price earns trust: not by being lowest, but by being checkable.
03
Production rates get corrected by reality. Rates built from what the crew actually achieved on comparable work — and revised after each job — converge on accuracy. Rates carried forward unexamined for years do the opposite.
The discipline behind good rates is unglamorous: record what the work actually took, by operation, on jobs you have already completed. Production rate is the variable that decides whether an estimate was right, and it is the one most often carried on assumption. Two coats over new drywall and two coats over a failed exterior coating share a description and share almost nothing else.
A note on square-foot rates
FAIME does not publish per-square-foot pricing, and treats a contractor who quotes one over the phone as a warning sign rather than a convenience. The same square footage can differ by a wide margin depending on substrate condition, access and height, detail density, system specification, and whether a water source has to be repaired first. A rate quoted before those are known is a guess wearing the costume of a price.
Takeoffs and tender submissions
A takeoff is a measurement, and its only real virtue is that someone else can reproduce it. Measure by the unit the work is actually performed in — area for coatings and boarding, linear measure for trim, joints and sealant, count for openings and fixtures — and keep the measurement basis visible so a reviewer can follow it.
The errors that recur most often are structural rather than arithmetic:
- Deducting openings that are, in practice, still worked around and still cost labour
- Measuring the design condition when the existing condition is what gets prepared
- Missing the detail work — returns, reveals, soffits, bulkheads — that carries disproportionate labour per unit
- Pricing one mobilization for work the schedule will inevitably split into three
- Ignoring restricted hours on occupied buildings, which changes the production rate, not just the start time
The submission itself is a document that gets compared against several others, often quickly. Make comparison easy: lead with the scope, present quantities and rates in the reviewer’s order rather than your own, state exclusions plainly, confirm schedule and manpower, and attach the compliance package rather than promising it. A tender that answers the estimator’s next three questions before they ask is the one that survives the shortlist.
Then be reachable. A price that cannot be clarified within a day of a question is a price that gets set aside, regardless of what the number said.
How FAIME quotes
Every FAIME estimate starts with a free site visit, because pricing finishing and envelope work from drawings alone means pricing the design rather than the building. Quotes go out as a written document with inclusions, exclusions and assumptions stated separately from the number, and the products and finish levels named.
Where a scope is repetitive — suite turnovers, multi-unit programs, corridor and stairwell work — we price it on unit rates so that quantity changes settle as arithmetic instead of negotiation. WSIB clearance and the certificate of insurance go out with the quote rather than after award, and workmanship carries a two-year warranty.
What we do not do is quote a rate before seeing the work. If you need a number today for a budget, say so and we will give you a range with the assumptions it rests on, clearly labelled as a budget figure — and then confirm it properly after a site visit. Request an estimate or get in touch.
