WHO · HOW · WHYEditorial standards
ProjectMeter publishes planning tools and practical guidance for people making real material, budget and maintenance decisions. Every page should explain what it knows, how it was produced and where its limits begin.
01Who creates the content
The ProjectMeter Editorial Team develops the site's calculators, explanatory copy and source notes. We use an organization byline because we do not invent individual credentials or imply a trade license that has not been independently verified.
02How calculators are checked
Formulas are implemented in a shared typed calculation library. Worked examples, rounding boundaries, unit conversions and invalid inputs are covered by automated tests. Interactive models are checked at desktop and mobile sizes.
03How guidance is sourced
Safety-sensitive and market-data pages link to the manufacturer, public agency or primary reference used. Cost ranges remain planning context, not a quote; product instructions and local requirements control the final decision.
04Why pages are updated
A review date changes only after the formula, source set, safety boundary or substantive guidance has been checked. We do not refresh dates merely to make an unchanged page appear new.

REPAIR GUIDESVisible checks only → explicit stop line → manufacturer/public-safety sources
Automation and human responsibility
Software assists with calculations, consistency checks and page production. It does not replace source verification, editorial judgment or a qualified professional. Pages are designed to help a visitor complete a planning task—not to manufacture search variations.
