1. General information only

The calculators, guides, tool descriptions and other content on this website are provided for general educational and planning purposes. They do not replace the judgement of a licensed civil or structural engineer, architect, surveyor or contractor.

2. Calculators give estimates

Calculator results depend on the numbers you enter and on standard assumptions such as wastage percentages, volume factors, mortar ratios and unit conversions. Real quantities and costs vary with design, site conditions, workmanship, material quality, local practice and market rates. Always add a safety margin, confirm quantities from approved drawings, and get written quotations before you buy or build.

3. Structural and safety work

Never use this website to decide structural sizes, reinforcement, foundation design, load capacity or other safety-critical matters. These must be designed and approved by a qualified engineer and must follow the building codes and regulations that apply where you build. Follow safe working practice and use proper protective equipment on any site.

4. Local rules differ

Building codes, approvals, material standards, units and prices differ between countries, cities and even neighbourhoods. Check the requirements of your local authority before you start. Some units, such as marla and kanal, vary by region.

We try to keep the content accurate and up to date, but we make no promise that it is complete, current or error-free. The website is provided “as is”. To the fullest extent allowed by law, BuildNDE and its owners are not liable for any loss, damage, delay or injury arising from the use of, or reliance on, the website or its tools.
