SiteworkMath — cubic-yard markConstruction math from people who’ve thrown the wheelbarrow.

Editorial policy

SiteworkMath is written and edited by James Wu. The site publishes calculator-driven research, not hot-take opinion. This page documents the standards every page is held to.

Sourcing

Numbers and claims come from primary references — see /methodology for the tiered source model. Pages cite by name, not by vague phrasing like “experts say.”

Review cadence

Each page lists a “Updated” date. Bag yields, box-coverage tables, and manufacturer waste-factor norms are re-checked when the relevant data sheet (Quikrete, Sakrete, Daltile, MSI, decking manufacturers) is revised. Building-code citations (IRC, ANSI, ACI, AWC DCA-6, TCNA handbook) are re-checked annually against the current published edition. Real-flip cost ranges and field-practice notes are durable claims; they don't carry a refresh cadence.

AI policy

AI tools assist with drafting and editing. Every number, formula, and source citation on this site is human-verified before publish — AI is not trusted to invent specifics. Pages that include any AI-assisted feature (such as the on-site assistant) carry a visible disclosure.

Corrections

If a page has a factual error, email admin@siteworkmath.com. Corrections are made promptly and the page's “Updated” date reflects the change.
