Where the Construction Dollar Goes: The 2026 Stage-Cost Benchmark
Ibex Research · June 2026 · 4 min read
If you want to find procurement savings in a construction business, start by knowing where the money concentrates. NAHB's Cost of Construction Survey, built from more than 4,000 builders, gives the most rigorous public answer: interior finishes carry 21.7% of construction cost, MEP rough-ins 19.2%, framing 16.6%, exterior finishes 13.4%, foundations 10.4%, site work 7.6%, and final steps 6.5%.
Three categories — finishes, MEP, and framing — carry over half of every construction dollar. For a $25M-volume firm, that's roughly $14.4M flowing through just three category families each year. Procurement effort should follow that concentration: a 3% improvement in interior finishes is worth more than a 15% improvement in final-stage landscaping.
What the concentration means for sourcing
Concentrated spend is leverageable spend. Categories with high volume support competitive bids, volume-tier pricing, and structured contracts; thin categories rarely justify the effort. The practical sequence for a mid-size firm: benchmark the top three families first, competitively bid whichever has gone longest without one, and put written agreements with defined pricing mechanics on every supplier above a volume threshold.
The survey also recorded a structural shift worth knowing: construction costs now account for 64.4% of the average new-home sales price — the highest share in the survey's history since 1998, up from 60.8% in 2022. The build itself, not the land or the margin, is eating the price. That is precisely why procurement has moved from back-office task to margin lever.

The Volatility Tax: What 2025's Material Price Moves Cost Buyers
Ibex Research · June 2026 · 4 min read
Headline inflation in construction inputs looked tame in 2025: overall input prices rose 2.8% for the year, with nonresidential inputs up 3.2%. The averages hide the damage. Tariff-exposed and supply-constrained categories moved violently: primary nonferrous metals climbed nearly 62% over twelve months, aluminum mill shapes rose 34.1%, framing lumber's composite jumped 23.5% year over year, copper wire and cable gained more than 22%, and steel mill products rose 15.4%.
Call it the volatility tax. A firm buying at list price absorbs each of those moves in full. A firm with contract structure — commodity-indexed pricing, escalation caps, defined pass-through documentation — pays the market move and nothing more. The difference between the two on a single $1.2M electrical category in a +22% copper year can run tens of thousands of dollars, and most mid-size firms have several categories exposed at once.
The three contract mechanics that matter
First, indexation: tie pass-throughs to the published commodity index, not the supplier's discretion. Second, caps and collars: bound the escalation both directions so budgeting survives the spike. Third, documentation rights: require the supplier to show the commodity movement behind any increase. None of these reduce the market price of copper. All of them stop margin from being taken on top of it.
The same discipline applies in every asset-intensive vertical — fuel in logistics, resins and metals in manufacturing, services labor in facilities. The index changes; the mechanics don't.

Why Mid-Size Operators Overpay, and the 60% That's Recoverable
Ibex Research · June 2026 · 5 min read
Mid-size asset-intensive firms don't overpay because anyone is careless. They overpay because the structure of the business guarantees it: procurement is distributed across operators optimizing for schedule, supplier relationships are inherited and unbenchmarked, and nobody owns the purchasing function as a discipline. Each of those is rational locally. Together they produce systematic overpayment.
What "addressable" actually means
Not every dollar of spend responds to sourcing discipline. Permits, impact fees, and some administered services are priced outside the market. But the materials, equipment, and indirect categories — roughly 60% of total spend in most asset-intensive businesses — are sourcing-eligible: they can be competitively bid, contractually structured, or volume-aggregated. On a $25M firm, that's about $15M of addressable spend.
Against that base, the documented numbers are consistent: construction buying groups report 5–7% annual hard-cost reductions (CNBA, 2026), and cross-industry group purchasing averages run higher still, with typical indirect-spend reductions of 10–25% reported across sectors. Taking only the conservative construction-specific range, a $25M firm's recoverable figure is $750,000 to $1.05M annually.
Why it stays unrecovered
Because recovering it requires three things mid-size firms structurally lack: visibility (categorized spend data), benchmarks (knowing what market price is), and bandwidth (someone whose job is to act on both). The fix doesn't require a procurement department. It requires the analysis once, the contract structure where it counts, and a recurring discipline — owned by someone, internal or fractional, who is accountable for the number.
