Editorial Standards & Data Methodology
Buildermuse publishes construction data, cost benchmarks, and original reporting for contractors, estimators, and construction business owners. This page explains where our numbers come from, how often they are updated, how we calculate our cost figures, and the editorial standards behind our articles. We publish it so readers can judge the reliability of what they read here and reproduce our numbers from their public sources.
Where our data comes from
Every dataset on the site is built from primary public sources — government statistical agencies, federal spending records, and public business registries — rather than scraped or resold third-party data. Each source below lists the series we use, what we use it for, and how often we refresh it.
U.S. Bureau of Labor Statistics (BLS)
Series: QCEW (construction wages by state, NAICS 23), CES (employment), PPI (material producer prices)
How we use it: State construction wage indexes, employment trends, and the material price movements behind our cost adjustments.
Refresh cadence: Monthly / quarterly, refreshed as BLS publishes
U.S. Census Bureau
Series: Construction Spending (VIP), Building Permits, Housing Starts
How we use it: National and regional construction activity, permit volume, and housing production.
Refresh cadence: Monthly
USASpending.gov
Series: Federal contract awards (NAICS 23)
How we use it: State-by-state federal construction contractor rankings, award totals, and agency/NAICS breakdowns.
Refresh cadence: Refreshed on a rolling basis; awards shown with fiscal-year context
Federal Reserve (FRED)
Series: HOUST, PERMIT, MORTGAGE30US, lumber and steel indexes, PPI series
How we use it: Housing starts and permits, mortgage rates, and material price benchmarks in our stats and price pages.
Refresh cadence: Refreshed as FRED updates the underlying series
OSHA
Series: Inspections, violations, and fatality data
How we use it: Construction safety reporting and the most-cited violation categories.
Refresh cadence: Periodic, as OSHA publishes
Federal Highway Administration (FHWA)
Series: State DOT budgets, bridge conditions
How we use it: Infrastructure and public-works coverage and state funding context.
Refresh cadence: Annual / as published
SAM.gov
Series: Open federal construction solicitations
How we use it: The federal bid listings on our Bids page.
Refresh cadence: Daily refresh
Google Places
Series: Local contractor and supplier business data
How we use it: The contractor and supplier directories — business names, locations, ratings, and contact details.
Refresh cadence: Refreshed periodically; each directory page shows its refresh date
How we calculate construction costs
Our cost figures are 2026 planning ranges, not quotes. National cost bands are compiled from published industry cost data and cross-checked against our own material price tracking. Because materials are priced nationally but labor is local, our state-by-state cost pages adjust only the labor portion of each cost band using the state's construction wage index from BLS QCEW (NAICS 23), relative to the national average.
Concretely, a page's state-adjusted cost equals the national cost multiplied by (material share + labor share × state wage index), where the labor share is a defensible fraction set per building type. We do not fabricate regional material pricing, so the adjustment is deliberately modest and is always labeled with its source. Every cost page shows the tiers (budget through luxury), the cost breakdown by component, and the factors that move the final number.
These figures are planning tools. Before committing a budget, confirm scope and pricing with local bids — our free cost estimator lets you model your own project with local inputs.
Editorial standards
Articles are written by our editorial team of construction-industry writers, each with a defined beat — residential and jobsite reporting, safety and labor, economics and bidding, and infrastructure and public works. Every article leads with specific, verifiable numbers and cites named data sources (BLS, Census, FHWA, OSHA, ENR, Dodge, NAHB, and the agencies above). You can see each writer and their beat on our team page.
We write to a consistent quality bar: original reporting and analysis rather than rewritten press releases, concrete figures in every section, and practical takeaways an estimator or owner can act on. When source data is revised, we update the affected pages; when we get something wrong, we correct it and note the correction.
Buildermuse is independent. Our data, directories, and cost tools are free, and our rankings and reporting are never influenced by payment. Where a page includes a paid or sponsored placement, it is labeled as such.
