New Nonresidential Building Construction Prices: BLS PPI Scenario Walk-Through
Commercial general contractors and trade subcontractors frequently encounter project scopes where historical cost baselines no longer match current market realities. To understand how output pricing for commercial facilities has evolved, estimators track federal price measures. A practical way to apply these metrics is through a step-by-step scenario evaluating the headline data series for nonresidential structures.
The Scenario: Evaluating Commercial Price Movement on Bid Day
Imagine an estimator reviewing an upcoming commercial building package. The owner's initial budget was modeled several years ago, but the work is heading to procurement today. Rather than relying on gut feelings about industry-wide inflation, the estimating team turns to official statistics published by the U.S. Bureau of Labor Statistics under Producer Price Index (PPI) commodity code WPU8011, titled Construction (partial)-New nonresidential building construction. This index measures output price movement with an index base period of June 2009 = 100.
By stepping through specific benchmark dates within the data window spanning January 2019 to September 2026, the team can establish exact baseline comparisons to evaluate owner budgets, risk exposure, and contract terms.
Step 1: Measuring One-Year and Two-Year Cost Adjustments
The estimator first checks the most immediate operational window. For September 2026, the latest available index value stands at 186.2 (raw 186.243). Comparing this to earlier autumn figures reveals the pace of recent cost adjustments:
- One year earlier: In September 2025, the index was 176.7 (raw 176.749). The change to the latest figure reflects an increase of +5.4%.
- Two years earlier: In September 2024, the index was 175.5 (raw 175.477). The increase to the latest level is +6.1%.
These figures show that while output prices rose moderately between 2024 and 2025, the subsequent twelve months saw an additional +5.4% lift. When contractors evaluate proposals, knowing these shifts helps support bid exclusions and clarifications when bidding on scopes scoped during earlier budget cycles.
Step 2: Tracking Long-Term Drift Against Past Budgets
Next, the scenario turns to projects planned several years prior. If an owner's capital improvement plan dates back to September 2021, when the index value sat at 134.7 (raw 134.664), the change to latest September 2026 reaches +38.3%.
Taking the scenario back to the pre-pandemic benchmark of January 2020, the index value was 127.2 (raw 127.200). That represents a cumulative increase of +46.4% to the latest reading of 186.2. Annual averages illustrate this steep climb across the historical timeline:
- 2019: 124.9
- 2020: 128.0
- 2021: 134.6
- 2022: 161.4
- 2023: 174.2
- 2024: 174.3
- 2025: 177.2
- 2026 (January-September only): 183.3
This multi-year trajectory highlights why bids based on older historical unit costs inevitably fall short on modern nonresidential projects.
Step 3: Checking Short-Term Stability and Revision Rules
In the final phase of the walk-through, the team checks short-term volatility across the last 13 months. The monthly index values show:
- September 2025: 176.7
- October 2025: 179.8
- November 2025: 179.7
- December 2025: 179.6
- January 2026: 181.7
- February 2026: 181.8
- March 2026: 182.0
- April 2026: 181.7
- May 2026: 181.9
- June 2026: 182.0
- July 2026: 186.2
- August 2026: 186.2
- September 2026: 186.2
The month-over-month change from August 2026 to September 2026 was +0.0%, with July, August, and September holding steady at 186.2. This reading matches the highest monthly value in the data window (January 2019 to September 2026), sitting +0.0% versus that high and well above the window low of 122.6 (raw 122.600) recorded in February 2019. Estimators tracking these numbers should note that all data are not seasonally adjusted, and recent months remain preliminary and subject to revision for four months.
PPI Benchmark Summary Table
The table below summarizes the key price points extracted during this walk-through from the BLS PPI commodity series WPU8011.
| Period Benchmark | Index Value | Change to Latest (September 2026) |
|---|---|---|
| Latest Month (September 2026) | 186.2 | +0.0% |
| One Year Earlier (September 2025) | 176.7 | +5.4% |
| Five Years Earlier (September 2021) | 134.7 | +38.3% |
| Pre-Pandemic (January 2020) | 127.2 | +46.4% |
| Series Window High (September 2026) | 186.2 | +0.0% |
Contractors structuring multi-year commercial commitments can utilize documented benchmark indices to support price escalation clauses that reflect actual market movement across long project timelines.
