How We Research, Review, Update & Correct
This ConcreteSwift Editorial Policy explains how content on ConcreteSwift.com is researched, calculated, reviewed, updated and corrected. It applies to our concrete quantity calculators, ready-mix cost estimates, bag estimates, conversion tools, construction guides and supporting educational content. Our goal is to make formulas understandable, assumptions visible, sources traceable and planning limitations clear.
Important technical claims should be grounded in primary, official or recognized industry sources where available.
Calculator logic, unit factors, reverse conversions and representative sample inputs are reviewed before publication.
Density, waste, price, thickness and other planning assumptions should be visible and editable when appropriate.
Confirmed errors are corrected, and time-sensitive pages are revisited when underlying information materially changes.
This policy governs the creation and maintenance of content across ConcreteSwift.com, including the main Concrete Calculator, slab and patio calculations, footing and pier calculations, wall calculations, column and beam calculations, bag estimates, ready-mix material-cost estimates, unit converters, location-based concrete cost guides, construction explainers, how-to articles and policy pages.
It is designed to help readers answer four practical questions: Where did this information come from? How was the calculation checked? What assumptions are being made? What happens if something is wrong or becomes outdated?
ConcreteSwift’s homepage follows the same principle in practice: users select a project shape, enter finished dimensions, choose an ordering allowance, and receive cubic-foot and cubic-yard estimates. For smaller jobs, the site can also estimate common bag quantities, and for ready-mix projects it lets users enter a local price per cubic yard rather than forcing one national price.

ConcreteSwift does not treat page count as a substitute for checking formulas, facts, units and assumptions.
ConcreteSwift estimates should be labeled as estimates and should not look more exact than the measurements or local price inputs justify.
Readers should be able to see important defaults, limitations, sources and commercial disclosures.
ConcreteSwift chooses sources according to the claim being made. For unit definitions and conversion factors, official measurement authorities are stronger than general blogs. For concrete practice, recognized technical organizations and standards bodies are preferred. For a local ready-mix price, a recent supplier or credible local cost source may be more relevant than a national average. We do not apply one source hierarchy blindly to every topic.
| Source Type | Examples | How We Use It |
|---|---|---|
| Primary / official | Government agencies, standards bodies, official code resources | Preferred for units, regulations, adopted requirements and formal standards |
| Industry technical | NRMCA, ACI and comparable technical organizations | Preferred for concrete practice, terminology and technical education |
| Local supplier / contractor | Ready-mix producers, local contractors, pump companies | Useful for current local pricing, service areas and stated policies |
| Established cost guides | Recognized home-improvement and construction cost publishers | Useful for triangulating price ranges, never treated as a guaranteed quote |
| Secondary web sources | General articles and summaries | Used cautiously and checked against stronger sources when claims are important |
| User-generated content | Forums, comments, social posts | May reveal real-world questions but is not normally used as sole technical authority |
Examples of external reference organizations that may be used across technical content include the National Ready Mixed Concrete Association (NRMCA), the American Concrete Institute (ACI), NIST for measurement guidance, and official state or local building-code resources when jurisdiction-specific requirements are discussed.
ConcreteSwift calculator pages receive a different kind of review from ordinary articles because a small logic error can affect every result. This is especially important for the project shapes used on the homepage—slabs and patios, round footings and piers, poured walls, and columns or beams—because each shape uses a different volume formula. Before publication or after a major code change, we aim to review the following:
Confirm the mathematical relationship and required units.
Verify exact or standardized conversion constants when applicable.
Run simple values whose answers can be checked manually.
Where useful, convert the result back to the starting unit.
Check empty, zero, decimal and invalid inputs plus mobile display.
Confirm that unit names, symbols and result descriptions match the calculation.
Example: a pounds-per-cubic-foot to kilograms-per-cubic-meter converter should not only multiply by a factor. The page should also confirm that the factor corresponds to the correct density units, test a known sample, check the reverse relationship, and make sure “lb/ft³” is not accidentally displayed as “lb/yd³.”
ConcreteSwift treats concrete cost content as time-sensitive and local. The homepage already reflects this by asking users to enter their own ready-mix price per cubic yard for a basic material estimate. Location-based cost guides follow the same principle: a single national or statewide average may not represent the price offered by a specific ready-mix plant, contractor or delivery zone, so dated ranges and editable assumptions are preferred.
Material-only concrete pricing should not be presented as an installed contractor price. Likewise, an installed slab estimate should distinguish concrete, waste, short-load fees, pumping, reinforcement, base preparation, demolition, labor, finishing and other major components where those items materially affect the result.
How-to guides are written for education and project planning. They should not imply that a general article can replace site-specific engineering, permits, code review, inspection, testing or experienced trade judgment.
When a topic involves structural loads, reinforcement design, foundation sizing, significant demolition or other higher-risk work, ConcreteSwift avoids presenting a generic material calculator as a structural-design tool. This is consistent with the homepage, which states that quantity calculators estimate material volume and do not determine structural thickness, reinforcement, concrete strength, bearing capacity or code compliance. Readers should be directed to project plans, adopted codes, manufacturers, inspectors or qualified professionals as appropriate.
Our goal is to publish original explanations rather than reproduce other websites. External sources may be used to verify a fact, define a standard relationship or support a technical statement, but the resulting article should be written in original language and should add useful structure, examples, calculations or context.
Short quotations may be used when the exact wording is important and legally appropriate, but long copied passages are avoided. Images, diagrams and tables should be original, licensed, public-domain or used with appropriate permission. A citation does not automatically make copying acceptable.
ConcreteSwift may use AI-assisted tools as part of the editorial workflow for tasks such as outlining, language refinement, repetitive formatting, generating calculator test cases or organizing source material. AI-generated text is not considered a source and is not automatically presumed accurate.
Before publishing material that was assisted by AI, important factual claims, formulas, conversion factors, links, price dates, technical terminology and recommendations should be checked against reliable references or independently verified calculations. Obvious hallucinations, invented citations and unsupported claims are not acceptable.
Practical rule: if a statement matters enough that an incorrect answer could change the amount of concrete ordered, the expected cost, a unit conversion or an important construction decision, it deserves an independent check.
A simple overview of how an article or calculator moves from idea to published resource.
ConcreteSwift readers should be able to report an error without navigating a complicated process. If a formula, conversion factor, source, price, statement or link appears wrong, use the Contact Us page and include the affected ConcreteSwift URL plus a short description of the issue.
When a report is received, the issue should be checked against the strongest available evidence. If the published content is wrong, the page should be corrected. The significance of the correction determines whether a visible note is appropriate.
Material corrections should be prioritized because they can change how a reader interprets the page or uses a calculator result.
Not every page needs the same review schedule. A relationship such as 1 cubic yard = 27 cubic feet is stable. A ready-mix cost range, building-code edition or supplier policy can change much more quickly. Review priority is based on how likely the information is to change and how much harm an outdated answer could cause.
| Content Type | Review Focus | Typical Trigger |
|---|---|---|
| Unit converters | Conversion factor, inverse factor, symbols, rounding, sample calculations | When standards change or an error is reported |
| Concrete calculators | Formula logic, dimensions, density assumptions, waste logic, result labels | After functional changes and periodic QA |
| Cost guides | Price date, location, scope, source quality, editable assumptions | More frequently because prices can change |
| How-to guides | Safety context, technical recommendations, standards links, sequencing | When industry guidance or cited sources change |
| Code-related content | Jurisdiction, edition/date, official links, limitations | When adopted codes or rules change |
| Legal/policy pages | Site practices, disclosures, contact routes, consistency | Whenever business or editorial practices change |
A page may be updated because a source changes, a reader reports an issue, a calculator is redesigned, a price range becomes stale, an internal link changes, or a new authoritative reference materially improves the explanation.
Advertising and sponsorship can support a website, but they should remain distinguishable from editorial conclusions. Payment should not change a conversion factor, technical formula, safety limitation or source hierarchy.
If a page contains sponsored content, paid placement, affiliate links or another material commercial relationship, the relationship should be disclosed in a way readers can understand. The U.S. Federal Trade Commission publishes guidance on endorsements, reviews and disclosures, and that guidance may inform how commercial relationships are presented.
See the FTC's endorsement, influencer and review guidance for additional information about U.S. advertising-disclosure expectations.
If affiliate links are used, the possibility of earning a commission should be disclosed. Affiliate compensation should not determine whether a product is described as technically appropriate or whether its limitations are mentioned.
Product recommendations, where they appear, should be relevant to the page and should distinguish objective specifications from subjective preferences. A product or supplier should not be represented as approved by a standards organization merely because it references an industry standard.
Writers, reviewers or site operators should disclose a material relationship that could reasonably affect how a reader interprets a recommendation. Examples include direct sponsorship, ownership interest, paid consulting relationship, affiliate compensation or receiving a product specifically for review.
A conflict does not automatically make information false, but hiding a relevant conflict can reduce reader trust. Disclosure allows readers to judge the recommendation with appropriate context.
External links are included to help readers verify claims, reach primary sources or continue research. We do not control third-party websites, and external content may change after a page is published.
Linking to a standards body, government agency, supplier, contractor or publication does not imply endorsement by that organization. Where a third-party link becomes broken or materially changes, it may be replaced with a better source during a later review.
The site's calculators, estimates and guides are educational tools. They do not create an engineer-client, contractor-client, attorney-client or other professional relationship. They do not replace stamped plans, permits, inspections, material testing, site investigation, manufacturer instructions or advice from a qualified professional who can evaluate the actual project.
For additional limitations, see the Disclaimer, Terms of Use and Privacy Policy.
Concrete work is practical, local and detail-sensitive. Reader feedback can identify broken links, confusing wording, outdated prices or unexpected calculator behavior that automated checks may miss.
