The FRED Construction Escalation Index tracks quarterly economic indicators from the Federal Reserve Bank of St. Louis (FRED) — labor compensation, material PPIs, fuel prices, and equipment costs. Data refreshes monthly via a scheduled job.
The Regional Labor Cost Index compares construction labor costs across metro areas by weighting BLS OEWS wage data against a trade mix you define. Data refreshes annually via a scheduled job pulling the BLS OEWS metro-area release.
The Embodied Carbon & Cost Reference documents relative carbon and cost indices for common building materials across five systems (facade, roofing, ceiling, flooring, walkways). Calibrated from ICE Database v2.0 and cross-checked against industry sources.
