The standard series for bulk cement in a concrete-heavy construction contract, distinct from the broader ready-mix concrete price, which also carries aggregate and labor cost.
A starting point citing this series by name and code. Replace the bracketed terms with your contract's actual scope before use.
The [affected portion] of the Contract Price shall be adjusted using US PPI — Cement, Hydraulic (BLS series WPU1322), published by BLS. Base Period: the index value published for August 2026 (or the month of contract signing, if different) is the Base Value. Adjustment: at each Adjustment Date, the Current Value is the most recently published three-month average of the index (the Averaging Window). The Escalation Factor equals Current Value divided by Base Value. Cap: the Escalation Factor applied under this clause shall not exceed 1.10 or fall below 0.90 (a 10% cap and floor) in any single Adjustment Date, regardless of the index's actual movement. [Replace bracketed terms with your contract's actual affected-portion definition and adjustment-date schedule before use. This is a drafting starting point, not legal advice.]

Price escalation in a construction contract is a clause that adjusts the contract price for movements in the published price of a named material, fuel, or labor cost after the bid. It shifts material-price risk from the contractor to the owner, within a defined base period, formula, and cap.
Read more →A concrete and cement PPI escalation clause compares a current-period Producer Price Index value for cement and concrete products to the value at contract signing (the base period), turns that into a ratio, then applies the ratio to the contract price or affected line items. Construction is the classic use case for this clause, and it typically names the exact BLS series code, an averaging window, a publication lag, and a cap.
