Where material cost swings actually hit a construction budget

The lumber quote we priced a framing package on in the spring was not the lumber quote we bought at in the fall. The difference on that one order was larger than the entire paint scope on the same job. That is how material inflation actually shows up on a project: not as a slow creep across every line, but as a hard number on two or three lines, arriving the week the purchase order goes out.

The budget is not evenly exposed

Steel, lumber, copper, roofing membrane and concrete admixtures move with commodity markets and with whatever else is being built in the region that quarter. Doors, tile, plumbing fixtures and paint move slowly and rarely by much. So a budget's real exposure sits in structure, roofing, electrical rough-in and mechanical equipment, and an owner who wants to protect a number should look there first instead of padding the whole estimate by the same percentage. The flat contingency over-protects the finish schedule and under-protects the roof.

The gap between the estimate and the purchase order

An estimate is a snapshot on the day it is written. The risk is the time between that day and the day the material is actually bought. A project that spends six months in permitting and design revisions carries six months of exposure on every material it has not yet ordered. A project that goes from estimate to notice to proceed in three weeks carries almost none. When we price a job, we say how long the material pricing in it is good for, and we say which lines are quotes from suppliers and which are our own historical numbers, so the owner can see where the snapshot could move.

Buying early has a cost too

Locking pricing on steel, rooftop units, switchgear or storefront glazing early protects the number and often protects the schedule, since those are also the long-lead items. It also means committing money and finalizing design decisions sooner than an owner might like. Our recommendation on most commercial jobs is to release the structure and the mechanical equipment as soon as the drawings support it and to leave the finish selections open longer, because the finishes carry less price risk and more owner preference. That is a job-by-job call, and a principal of our company will sit down with the owner and make it line by line.

Alternates are planning, not concessions

A specification with one acceptable product is a specification with no way out if that product doubles in price or goes on a twenty-week lead. We ask the architect for approved alternates on the categories that have moved recently: a second roofing system, a second tile line, a second light fixture family that meets the same performance. It costs nothing to write them into the drawings and it can save a redesign and a month if the market turns while the building is framed. On the trades our own crews run, framing, drywall, millwork, stone, tile, paint, roofing, glazing and concrete, we can also shift labor to absorb a substitution without renegotiating with a subcontractor who priced the original product.

Say it early, say it in numbers

The worst way an owner learns about material inflation is a change order in month seven. The right way is a conversation in pre-construction: these four lines are exposed, here is what they have done in the last year, here is what buying them now would cost and what waiting could cost. From there the owner makes a decision with the numbers in front of them. The person having that conversation on our side is the same person who priced the job and the same person who will be on the site when the trucks arrive, so the advice does not change hands.

Material risk is also schedule risk. A product that becomes unavailable is a product that arrives late, and a late roof is a late everything. Protecting the opening date and protecting the number are the same exercise, and both start with knowing which lines can move.

We price jobs with the exposure written next to the number and the owner of the company on the site when the material arrives. Send over the drawings and we will show you where your budget is actually at risk and what it would take to close it.
