Clarity for the built environmentNo professional service or certification
The website provides general informational and educational decision-support tools. It does not provide architectural, engineering, quantity-surveying, valuation, legal, tax, financial, safety, procurement, contractual, regulatory, or other regulated professional advice.
A result is not a design calculation, tender, quotation, audit, compliance determination, regulatory approval, contractual instruction, professional opinion, or certification. Use of the website does not appoint the website operator or Hossam Farag as a consultant or create a duty to monitor or advise on your project.
Assumptions and limitations
Outputs depend on the information supplied, the tool’s stated scope, simplified assumptions, reference dates, units, exclusions, and methodology version. They may not reflect local law, contracts, market conditions, project complexity, taxes, currency movements, software licensing, minimum charges, risk allowances, or facts not requested by the tool.
Sources can become outdated or may apply only to a stated market, product, period, or scenario. An unknown, unsupported, or out-of-range case must not be treated as a reliable result.
Required review
Before using an output for procurement, budgeting, contracting, safety, design, compliance, investment, staffing, payment, or another material decision, verify the inputs and method and obtain review from appropriately qualified professionals with access to the full project context and current authoritative requirements.
No guarantee
Reasonable care is taken in preparing the website, but no guarantee is made that every calculation, source, assumption, result, or page is complete, accurate, current, suitable for a particular purpose, or free from interruption or error.
This disclaimer does not remove duties or liabilities that applicable law does not permit the website operator to exclude. The liability provisions in the Terms of use apply alongside this disclaimer.
