Same numbers as the chart, straight from BLS. Dates are the first of each period, the way BLS reports them.
Bar joists and rebar rose 30.0% over the last 12 months, more than any of its main inputs. Input costs are not adding pressure right now.

Over the 12 months to Sep 2026, the hot rolled steel price index rose 15.0% and this index rose 30.0%.
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 — Fabricated Bar Joists and Concrete Reinforcing Bars (BLS series WPU1074051), published by BLS. Base Period: the index value published for September 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.]
Used in concrete and foundation supply contracts where the buyer pays for fabricated reinforcing steel, not just mill bar. Because it blends bar joists with reinforcing bar and includes shop work, check it against a mill steel series or a regional rebar price before relying on it alone.
Divide the current value of BLS series WPU1074051 (Fabricated Steel Bar Joists and Concrete Reinforcing Bars) by its value at contract signing, then apply that ratio to the rebar part of the price. A usable clause also names an averaging window, a rule for revised values and missing months, and a cap.
Escalake tracks US PPI — Fabricated Bar Joists and Concrete Reinforcing Bars, applies your formula, and gives both sides a number they can confirm, no spreadsheet required.
