What this means for your clause

Indexes finished masonry units, not the raw cement or aggregate that goes into them. Use this when the contract buys block or brick directly, the cement series when it buys bulk cement for site-mixed concrete.

Draft a clause

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 — Concrete Block and Brick (BLS series WPU1331), 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.]

How this index is used

How do you calculate a concrete or cement price escalation clause using the PPI?

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.
