BuildCalc Journal Terms of Service

BuildCalc Journal · Published · Last updated

Quick answer

Using these free construction calculators means you accept that results are planning estimates, not engineering advice or price quotes. Verify quantities with local suppliers and building codes, use the site lawfully, and understand it is provided as-is, with liability limited as far as the law allows.

01 Acceptance of these terms

These Terms of Service (“Terms”) govern your access to and use of BuildCalc Journal, including every calculator, guide, feed and page on example.com (together, the “Service”). By using the Service you agree to these Terms and to our Privacy Policy. If you do not agree, please do not use the Service.

You must be old enough to form a binding contract where you live, or use the Service with a parent or guardian.

02 What the Service is

BuildCalc Journal provides free, browser-based construction calculators (concrete slabs, block walls, footings and Sonotube piers, rebar grids, driveway cost) and educational estimating guides for the United States, United Kingdom, Australia and New Zealand. No account is required.

03 Accuracy, codes and your responsibility

  • Formulas, bag yields, block sizes, bar weights and unit conversions are simplified. Real quantities vary with site conditions, subgrade, formwork, spillage, over-excavation, mix design and supplier practice.
  • Prices, tariffs and cost ranges are illustrative averages, not quotes, and change by region and over time. Always obtain written quotes from local suppliers and contractors.
  • Structural elements (footings, reinforced slabs, retaining or load-bearing walls, driveways carrying vehicles) must be designed to your local building code and soil conditions by a qualified professional.
  • You are solely responsible for verifying every result and for ordering, building and safety decisions made using the Service. Always add the contingency recommended by your supplier.

04 Acceptable use

You agree not to:

  • break the law or infringe anyone’s rights while using the Service;
  • scrape, crawl or copy the Service at a rate or in a manner that harms performance, or bypass technical limits, except for standard search-engine and answer-engine crawling permitted by our robots.txt;
  • attempt to probe, disrupt or gain unauthorised access to the Service, its hosting or its users;
  • use automated means to generate ad impressions or clicks, or otherwise interfere with advertising shown on the Service;
  • misrepresent our content as your own or imply our endorsement of your products or services.

05 Intellectual property and permitted use

The text, guides, diagrams, layouts, source code, calculators’ presentation and the BuildCalc Journal name and logo are owned by us or our licensors and protected by copyright and other laws. Underlying mathematical formulas and unit conversions are facts and are free for anyone to use.

You may use the calculators for personal or business planning, print or save your results, and quote short excerpts of our guides with a visible link back to the source page. Please contact us before republishing full articles, embedding our calculators or using our content for commercial datasets.

06 Advertising, links and third parties

The Service may show ads (for example through Google AdSense) and link to manufacturers, suppliers and other sites. Ads and links are provided for convenience; their presence is not an endorsement, and they never alter calculator results. We are not responsible for third-party content, products, prices or privacy practices; your dealings with them are solely between you and them.

07 Disclaimer of warranties

The Service is provided “as is” and “as available”, without warranties of any kind, express or implied, including accuracy, completeness, merchantability, fitness for a particular purpose, non-infringement or uninterrupted availability. We do not warrant that results are error-free or suitable for your project. Nothing in these Terms excludes rights you have under consumer-protection laws (including the Australian Consumer Law, the New Zealand Consumer Guarantees Act or UK consumer law) that cannot lawfully be excluded.

08 Limitation of liability

To the fullest extent permitted by law, BuildCalc Journal and its owners, contributors and suppliers are not liable for any indirect, incidental, special, consequential or punitive damages, or for loss of profits, data, materials, time or goodwill, including costs of over- or under-ordering materials, rework, project delays, structural failure, injury or property damage, arising from your use of, or inability to use, the Service — even if we were told such loss was possible.

Where liability cannot be excluded, our total aggregate liability is limited to the greater of USD 50 or the amount you paid us for the Service (which is nothing, as the Service is free). Nothing limits liability for death or personal injury caused by negligence, fraud, or anything that cannot be limited by law.

09 Indemnity

You agree to defend and hold us harmless from claims, losses and expenses (including reasonable legal fees) arising from your breach of these Terms, your misuse of the Service, or construction or purchasing decisions you make, except to the extent caused by our own wilful misconduct. This clause applies only where permitted by your local law.

10 Changes, availability and termination

We may change, suspend or discontinue any part of the Service, and update these Terms, at any time. The “Last updated” date at the top shows the current version; continued use after an update means you accept it. We may restrict access to anyone who breaches these Terms. Sections that by nature should survive termination (such as intellectual property, disclaimers and liability) continue to apply.

11 Governing law and disputes

These Terms are governed by the laws of the jurisdiction in which the site operator is established, without regard to conflict-of-law rules. Courts of that jurisdiction have exclusive jurisdiction over disputes, except that consumers may bring claims in their country of residence where mandatory local law gives them that right. Please contact us first at hello@example.com so we can try to resolve any concern informally. If any provision is held unenforceable, the rest remains in effect.

Frequently asked questions

Is it free to use the calculators?

Yes. Every calculator and guide on the site is free, requires no account and no email address.

No. Results are planning estimates of quantities and illustrative costs. Footings, reinforced slabs, load-bearing walls and driveways must be designed to local building codes by a qualified engineer or contractor.

Are the prices shown real quotes?

No. Prices and cost ranges are illustrative averages for the US, UK, Australia and New Zealand. Always get written quotes from local suppliers and contractors.

Can I copy or republish your guides?

You may quote short excerpts with a visible link back to the original page. Contact us before republishing full articles, embedding calculators or reusing content commercially.

Who is liable if my project needs more or less material than estimated?

You are responsible for verifying quantities and adding supplier-recommended contingency. To the extent permitted by law, we are not liable for ordering errors, rework, delays or damage resulting from use of the Service.
