How to handle material price increases mid-project

Read the contract first to see who carries the risk, give written notice the moment a supplier raises a price, document the original quote against the new one, look for ways to cut the impact, and then ask for relief through the change order or escalation process the contract provides.

When material prices rise in the middle of a job, start with the contract, because it decides who pays. If you have an escalation clause, follow its notice and documentation steps exactly. If you have a fixed-price contract with no clause, the increase is usually yours unless the owner agrees to share it, so your job becomes limiting the damage and making a well-documented request. Either way, act fast: lock prices on what is left to buy, give written notice, and keep the original quote and the new one side by side.

Price jumps on steel, copper, lumber, or electrical gear can turn a 12 percent job into a 4 percent job before anyone notices. The contractors who come out best are the ones who spot the increase on the first supplier email, not on the job cost report three months later.

Step 1: Find out who carries the risk

Pull the contract and look for these items:

  • An escalation or price adjustment clause. What materials it covers, what index or proof it uses, any threshold or cap, and the notice deadline.
  • Your bid clarifications. If you qualified pricing on specific items or limited how long your price was good, those terms may have carried into the contract.
  • Contract type. A cost-plus contract or time and materials work generally passes actual costs through. A fixed-price contract generally does not.
  • Force majeure and change clauses. A force majeure clause often gives time, not money. Read it rather than assuming.
  • Flow-down terms. Subcontractors should check whether the prime contract has an escalation clause that flows down, and what notice the GC needs to pass a claim up.

Federal jobs can be different. Some federal contracts include an economic price adjustment clause. One standard version, FAR 52.216-4, requires the contractor to notify the contracting officer within 60 days after an increase or decrease (unless the contracting officer approves a longer period in writing), caps total increases to any contract unit price at 10 percent of the original unit price, and applies decreases as well as increases. Check whether your contract actually includes it before relying on it.

Step 2: Give written notice right away

Many contracts require notice within a set number of days of the event, and missing it can waive the claim. Send a short letter or email to the owner or GC: which material, the quoted price, the new price, the expected cost impact, the date you learned of it, and that you are reserving your rights to an adjustment. Notice costs nothing, and it keeps options open.

Step 3: Document the increase

  • The original supplier quote with date and validity period.
  • The supplier's written price increase notice or new quote.
  • Purchase orders and invoices showing what you actually paid.
  • Quantities still to buy, from the estimate or bill of materials.
  • If your clause uses an index, the index values for the base date and the purchase date.

Indexes are useful even without a clause, because they show the increase was market-wide rather than a bad buy. The U.S. Bureau of Labor Statistics publishes the Producer Price Index, which measures the average change over time in selling prices received by domestic producers, with monthly releases.

Step 4: Cut the impact before you ask for money

  1. Lock the rest of the buy. Ask suppliers to hold a price on the remaining quantity and release the order now if you have storage and the contract allows billing for stored materials.
  2. Get competing quotes. The supplier raising prices may not be the only option.
  3. Offer alternates. An equal product may cost less. Submit a substitution request and get approval before switching.
  4. Re-sequence. If prices are expected to ease, check whether buying later is realistic without delaying the job.
  5. Talk to your subs. Their suppliers may face the same increase. Find out early, before it arrives as a surprise claim.

Step 5: Request an adjustment the right way

If the contract has a clause, submit the adjustment in the form it requires, usually as a change order request with backup. Without a clause, frame the request as a business conversation: show the documentation, the mitigation you already tried, and a fair proposal such as splitting the increase or adjusting the schedule. Owners and GCs are often more open to a shared solution when they can see the numbers and know the job is at risk.

Worked example: copper wire on an apartment job

Here is an illustration. Say an electrical subcontractor signed a $1.1 million fixed-price subcontract with a material escalation clause covering copper wire and conduit. The clause requires notice within 10 days of a supplier increase and covers increases above 5 percent of the quoted material price.

Example escalation calculation (illustrative figures)
LineAmount
Wire quoted at bid$140,000
Already purchased at bid price$50,000
Remaining wire at bid price$90,000
Remaining wire at new supplier price$108,000
Increase on remaining wire$18,000 (20%)
Threshold carried by sub (5% of $90,000)$4,500
Adjustment requested$13,500

The sub sends notice on day three with the original quote, the supplier's increase letter, and the remaining quantities. It gets a second quote that comes in $3,000 lower than the original supplier's new price, revises the request to $10,500 (the $15,000 increase minus the $4,500 threshold), and releases the remaining order immediately to cap further exposure. The GC passes the request to the owner under its own clause, and the change is approved in the next billing cycle.

Talking to the owner or GC about an increase

How you raise the issue affects the answer. Call before you send paper, so the first time the owner hears about it is not a formal claim. Explain what happened, what you have already done to limit it, and what you are asking for. Then follow up in writing with the documentation. Keep the tone factual. Owners respond better to "here is the supplier letter, here is our second quote, here is what we propose" than to a demand. If the contract gives you no right to an adjustment, say so plainly and present the request as a shared problem on a job both sides want finished on time.

Mistakes to avoid

  • Waiting for the invoice. The time to act is the supplier's notice, not the bill.
  • Missing the notice deadline. Late notice can kill a valid claim.
  • No proof of the original price. Keep dated quotes. Without them, an increase is just a number.
  • Asking for the whole increase on everything. Material already bought at the old price is not part of the claim.
  • Swapping products without approval. Unapproved substitutions create rework and back-charges.
  • Not updating the job cost forecast. Put the expected increase into cost to complete now, even if relief might come later.

Templates and tools that help

Use a construction change order template for the request and a change order log template to track it. For future bids, read how to write material escalation clauses and how to handle material price escalation in bids.

Smart Business Automator tracks change orders with their backup and shows the cost impact on the job's WIP view, so an escalation request does not sit unpriced. See change order approval automation.

Frequently asked questions

Can a contractor raise prices after signing a fixed-price contract?

Usually not on its own. A fixed price generally puts material risk on the contractor unless the contract has an escalation clause or the other party agrees to a change. Read the contract and get legal advice on specific disputes.

What should a material price increase notice include?

The material, the original quoted price and date, the new price, the estimated cost impact, the date you learned of it, and a statement that you reserve the right to an adjustment. Follow any form the contract requires.

Does force majeure cover material price increases?

It depends on the wording. Many force majeure clauses grant extra time rather than extra money, and some do not mention price at all. Read your specific clause.

How do I prove a material price increase?

Keep the dated original quote, the supplier's written increase, purchase orders, and invoices. A published index such as the Producer Price Index helps show the increase was market-wide.
