Material prices in construction are more volatile than ever. Lumber, steel, copper, PVC — all have seen dramatic swings that can turn a profitable project into a loss if you're not prepared.
Here's how to protect your business from material price volatility.
Why Material Prices Are So Volatile
Several factors drive construction material price swings:
Supply Chain Disruptions
Global supply chains are complex and fragile. A factory closure in Asia, port congestion, or shipping shortage can spike prices overnight.
Commodity Markets
Many construction materials (steel, copper, lumber) are tied to global commodity markets influenced by factors far beyond construction demand.
Tariffs and Trade Policy
Import tariffs can significantly impact pricing for materials sourced internationally.
Seasonal Demand
Some materials see seasonal price fluctuations based on construction activity patterns.
Economic Cycles
During construction booms, demand exceeds supply. During downturns, manufacturers cut production, which can cause shortages when activity returns.
Contractual Protection Strategies
Price Escalation Clauses
A price escalation clause allows you to pass material cost increases to the GC or owner. There are several types.
Fixed escalation: "Price will increase 3% if materials are purchased more than 6 months after contract signing."
Index-based escalation: "Steel prices will be adjusted based on the Engineering News-Record Construction Cost Index."
Documented escalation: "Actual material cost increases above 10% will be passed through with documentation."
Material Allowances
Instead of fixing material prices, include material costs as an allowance — an estimated budget that will be reconciled to actual costs. This shifts price risk to the owner while still giving them cost visibility.
Shorter Quote Validity
Limit how long your quotes are valid. "This quote is valid for 30 days" protects you from price increases during extended negotiation periods.
Exclusions
Clearly exclude specific volatile materials from fixed pricing: "Copper wiring priced as allowance due to market volatility."
Pricing Strategy Adjustments
Build in Contingency
Add contingency to your material estimates to buffer against increases. On volatile materials, 5-10% contingency may be appropriate.
Get Supplier Price Locks
Work with suppliers to lock in pricing for specific projects. This may require a deposit or commitment but provides certainty.
Time Your Purchases
If you have flexibility, time material purchases to take advantage of favorable pricing. Monitor price trends for your key materials.
Alternative Materials
Know what substitutes exist for expensive materials. If copper prices spike, are there aluminum alternatives? Having options provides negotiating leverage.
Communication with GCs and Owners
Early Warning
If you see material prices rising, communicate proactively. "Lumber prices have increased 15% since our bid. Let's discuss how to handle this."
Documentation
Document everything — supplier quotes, price indices, dated communications. If you need to request a price adjustment, documentation supports your case.
Proposed Solutions
Don't just present problems. Offer solutions: "We can absorb the first 5% increase, but anything beyond that needs to be shared."
Formal Change Order Process
Material price increases that affect contract value should go through the formal change order process. Document the increase, get approval, adjust the contract.
Managing Supplier Relationships
Build Relationships
Strong supplier relationships provide early warning of price changes, priority access during shortages, and flexibility on pricing and timing.
Multiple Suppliers
Don't depend on a single supplier for critical materials. Having alternatives gives you options and negotiating leverage.
Negotiate Payment Terms
If prices are high, negotiate better payment terms to reduce your cash flow burden.
Volume Commitments
If you can commit to volume across multiple projects, you may be able to negotiate better pricing or price protection.
Project-Level Strategies
Material Staging
On longer projects, consider purchasing and storing materials early if prices are expected to rise. Factor in storage costs and material degradation.
Value Engineering
Work with the design team to find cost-effective alternatives that meet project requirements without premium-priced materials.
Schedule Optimization
If possible, sequence work to purchase volatile materials when prices are favorable.
When You've Already Signed a Fixed-Price Contract
If you're locked into a contract and prices spike, your options are limited but not zero:
Review Your Contract
Check for any escalation provisions you might have overlooked.
Document the Increase
Build your case with market data, supplier quotes, and dated correspondence.
Request Consideration
Approach the GC professionally. Explain the situation and ask for consideration, even if not contractually required.
Negotiate Scope Adjustments
If price relief isn't available, perhaps scope adjustments or timeline extensions can help reduce your exposure.
Absorb What You Must
Sometimes you'll take a loss. Learn from it and protect yourself better on future contracts.
Frequently Asked Questions
Should I include escalation clauses in every contract?
For contracts extending more than 90 days, escalation protection is wise. For shorter projects, it may not be necessary.
How do I track material price trends?
Subscribe to industry publications like Engineering News-Record. Follow commodity markets. Talk to your suppliers regularly.
What if the GC won't accept escalation clauses?
You have options: build in higher contingency, shorten quote validity, price materials as allowances, or decline the job if the risk is too high.
