Resources
Tools, guides and insight for
construction professionals.
How the index is built, what it covers, how to read what it shows you, and where the limits are. Everything here is about this dataset — there is no filler.
Getting started with Hubstake
A step-by-step walk through finding a line item, reading the median and the middle-half range, and opening the document behind a price.
Read GuideHow to read a bid tabulation
What a bid tab actually is, what each column means, why the lowest total does not always win, and why an offered price is not an awarded one.
Read GuideUsing price trends in an estimate
How the quarterly median series is built, what a quarter with no observations means, and when a trend is long enough to lean on.
Read CoverageAgency coverage guide
Every agency in the index, what each contributes, how far back it goes and how current it is — regenerated on every build.
Read CoverageWhat the index does not cover
The states that publish averages only, the ones that need an account, and the ones that ask automated clients to stay out. Stated plainly, with reasons.
Read QualityData quality standards
The checks every row passes before publication: arithmetic reconciliation, contract-level reconciliation, unit consistency and receipt-link accuracy.
Read QualityItems with too little data to be a market
Why 170,679 of 251,133 items show no median, and what a low-confidence marker means.
Read UpdatesUpdate cadence and data currency
How often the index is rebuilt, how current each state is, and how to check before you rely on a number.
Read ReferenceDefinitions: median, p25–p75, sample depth
Exactly how each published figure is computed, and what is deliberately not done — no quantity weighting, no seasonal adjustment, no inflation indexing.
ReadNothing matches that.
Looking for something that is not here?
Coverage requests and corrections genuinely change what gets built next — the last four states in the index were added because someone asked. Tell us the agency or the item you need.
Get in touchStart with a real lookup
The fastest way to understand what the index is, is to search a line item you already know the price of and see whether we agree — then open the document and check.
