At tender close, the answer appears obvious. Bid A is $55,000 lower. But a tender price captures one moment. It does not automatically capture what happens during engineering, submittals, approvals, procurement, production, site coordination, installation, deficiencies and closeout.
That is not an argument for the higher number. Bid B is not automatically better, and Bid A is not automatically a risk. It is an argument that the two numbers on the bid form and the two projects that follow are different measurements — and that most of the money that moves on a commercial package moves after the bid form is filed.
Tender price is visible.
Execution cost isn't.
The bid is only the starting line
What a bid captures
Scope assumptions, specifications, quantities, labour assumptions, material pricing, supplier quotations, installation assumptions, schedule assumptions, exclusions, allowances and the site conditions the estimator understood on the day.
What it cannot perfectly predict
Future revisions, delayed approvals, site readiness, owner changes, supplier price changes, unexpected conditions, sequencing changes and schedule compression.

The price may not have changed because someone made a mistake. The assumption may simply have expired.
A subcontractor tenders using the supplier pricing available on bid day. Actual purchasing may happen weeks or months later. In between, supplier quotes can expire; freight, exchange rates and lead times can move; specifications can change; approved equals may be required; availability and production capacity can shift; and tariffs or duties can change.
That last point is not hypothetical in 2026. Statistics Canada's builders reported in the second quarter that retaliatory tariffs between Canada and the United States disrupted supply chains and that regulatory uncertainty delayed purchases[2]. The Bank of Canada described the trade situation in September as "fluid"[3]. A 90-day gap is a long time to hold a price in a fluid market.
Related Sandha Industry BriefingThe $500,000 Millwork QuestionThe seven costs you don't see on bid day
01Engineering delay
Shop drawings, RFIs, field dimensions, consultant comments, coordination drawings, MEP conflicts and site conditions all have to resolve before a manufacturer can cut material. When that work starts late or loops, production does not get more days — it gets fewer.
- 5 days lost here
- can become a much bigger problem later
There is no reliable multiplier for this, and we will not invent one. The point is directional: a week lost in coordination is usually recovered — if it is recovered — in the most expensive part of the job.
02Approval latency
- Subcontractor
- GC
- Consultant
- Owner
- Return
Each review period in that chain may be perfectly reasonable on its own. Stacked together, and repeated for a revision cycle, they can quietly consume the window that procurement was counting on. This is not a criticism of architects, GCs or owners. It is a system-coordination problem, and it belongs to everyone in the chain.
03Procurement timing
Long-lead items, quote validity, material release, country of origin, specialty hardware, custom finishes, approved alternates and supplier allocation all run on their own clocks — and none of them is the master schedule.
A project can be on schedule on paper and late in procurement.
04Site readiness
Materials arrive. Then the questions start:
- Floors are incomplete
- Walls are not ready
- Elevators are unavailable
- Access is blocked
- Power is unavailable
- Preceding trades are still in the area
- Environmental conditions are unsuitable
- Dimensions have changed
Delivery is not the same as installation readiness.
05Schedule compression
Time lost upstream rarely moves the opening date. More often, downstream trades are asked to recover it — with overtime, additional crews and stacked trades working in the same area. That can be done well. It can also reduce productivity, add coordination complexity and raise quality risk, depending on the crew, the scope and how long the compression lasts. Compression is a cost decision, even when nobody records it as one.
06Remobilization
Planned
- Mobilize
- Execute
- Complete
Fragmented
- Mobilize
- Partial install
- Leave
- Return
- Finish
- Return for deficiency
Every additional movement carries travel, set-up, protection, re-orientation and supervision. No single trip looks expensive. Three extra trips on every area of a multi-floor job is a different conversation.
07Closeout drag
The last 5% can consume a disproportionate amount of attention.
Deficiencies, touch-ups, missing hardware, replacement parts, damaged pieces, access coordination, warranties, manuals, closeout documentation, holdback and final invoicing. Each item is small. Each needs someone to schedule it, attend it, document it and confirm it. Repeated small tasks are where project-management time goes after everyone else has moved on.
Follow one project
Two bids. Same drawings. Different journeys.
A commercial interior package. Bid A at $910,000; Bid B at $965,000. We are not going to tell you which bidder is better. Instead, here are two ways the same package could be executed.
Path A
- Bid
- Multiple revisions
- Late approval
- Quote expires
- Delayed procurement
- Site not ready
- Split installation
- Remobilization
- Closeout
Path B
- Bid
- Early coordination
- Approvals tracked
- Critical materials released
- Site readiness confirmed
- Planned installation
- Closeout
Either bidder could follow either path. The lower bidder might run Path B beautifully; the higher bidder might drift into Path A. The lesson is not "pay more."
Understand how the project will be executed — not only what it costs on bid day.

The forward view points the same way. BuildForce Canada's 2026–2035 outlook expects Ontario non-residential investment to keep growing into the late 2020s, driven by institutional, government, commercial, heavy industrial and civil projects[4]. More work in the pipeline means more packages competing for the same engineering hours, review capacity, shop floors and installation crews. Nationally, there were 3.0 unemployed persons for every job vacancy in Q2 2026[5] — but a general labour figure does not tell you whether a specialist installer is available the week your site is finally ready.

Read together: more activity, a cost base still rising, and uneven movement inside the divisions that make up an interior package. Metals moved roughly four times faster than wood, plastics and composites over the year[2]. A single millwork package that mixes both carries two different price clocks.
The cost of a revision depends on when it happens
Drawing
Often incorporated digitally — a revision, a re-issue, a review.
Procurement
May involve purchasing changes, cancelled orders or new lead times.
Production
May involve remaking components already cut, edged or finished.
Site
May involve removal, access, protection and remobilization.
This is a qualitative pattern, not a cost curve, and not every change follows it. But the direction is consistent enough to plan around.
The drawing is often the best place to solve a problem.
The site-readiness test
Before delivery
- Access confirmed
- Area released
- Dimensions verified
- Flooring / preceding work ready
- Power available where required
- Elevator / loading access booked
- Storage plan confirmed
- Installation sequence confirmed
- Other trades coordinated
- Protection requirements confirmed
If three of these are unknown, is the project actually ready for delivery?

President's perspective
I don't think the construction industry has a bidding problem as much as it sometimes has a handoff problem.
A project moves from estimating to project management, from project management to engineering, from engineering to purchasing, from purchasing to production, and eventually to site. Every one of those handoffs carries information — what the estimator assumed about access, which hardware the price was built on, how long the supplier said the number would hold, which dimensions were taken from drawings and which still need to be measured.
If an assumption disappears during one of those handoffs, nobody notices at the time. The project pays for it later, usually on site, usually when there is the least room to absorb it.
On our own floor, the conversations that save the most money are rarely about price. They are the ten-minute calls in week three: this finish has a long lead, this wall isn't where the drawing says, this approval is sitting with someone who's away. None of that is dramatic. All of it is cheaper to deal with in week three than in week fourteen.
The best project teams I see are not the teams that never encounter a problem. They are the teams that expose the problem early enough to still have options. That is a habit, not a price point — and it is available to every bidder on the list.

The boardroom test
Before you award the next package, ask these 10 questions.
- 1What assumptions are built into this number?
- 2How long is supplier pricing valid?
- 3What has the longest lead time?
- 4When must shop drawings be approved?
- 5Which dimensions require field verification?
- 6What decisions could delay procurement?
- 7What must be ready before delivery?
- 8What happens if the installation window moves?
- 9How are revisions controlled after award?
- 10What does closeout actually require?
If the project team can answer all ten before production begins, price becomes only one part of a much better conversation.
