Preliminary Design Tool — Not for Final Engineering

All calculations produced by MEPMate are for preliminary estimation and design guidance only. They must be verified and certified by a qualified, licensed MEP engineer before being used for construction, procurement, regulatory submission, or any safety-critical application.

📐 Calculations for Preliminary Design Only

MEPMate's calculators are engineering tools designed to assist professionals in the early stages of design — concept, schematic, and design development phases. They are not intended to replace detailed engineering analysis.

Results produced by MEPMate should be treated as:

  • Starting points for detailed design, not final design values.
  • Rough estimates for feasibility studies and preliminary budgeting.
  • Quick checks to validate orders of magnitude, not precise outputs.
  • Educational references to understand engineering principles.
Do Not Use For

Structural sizing decisions, regulatory compliance submissions, safety system design, construction tendering, or any application where an error could result in financial loss, property damage, or personal injury — without independent professional verification.

👷 Verify with a Licensed Engineer

In India and most international jurisdictions, MEP systems in buildings must be designed, stamped, and certified by a licensed professional engineer. MEPMate does not provide this certification.

Always ensure that:

  • A registered Chartered Engineer (CEng) or equivalent licensed professional reviews all MEP designs.
  • Calculations submitted to authorities having jurisdiction (AHJ) are prepared or countersigned by a licensed engineer.
  • On-site conditions are assessed by a qualified professional, as MEPMate calculators cannot account for site-specific variables.
  • Final designs are peer-reviewed and comply with all applicable local, state, and national codes.
Our Goal

MEPMate is designed to make engineers more efficient, not to replace engineering judgement. Our tools help you get to the right answer faster — but the professional responsibility remains with the engineer of record.

📚 IS Code Versions May Change

MEPMate's calculators are implemented based on specific versions of Indian Standards (IS codes), the National Building Code (NBC), and international standards such as ASHRAE, IEC, and BS. These standards are periodically revised by their respective bodies.

The following standards are referenced across MEPMate calculators:

IS 3792
HVAC — Ventilation requirements
IS 732
Electrical — Wiring installations
IS 1239
Plumbing — Steel pipes & fittings
IS 15105
Fire — Sprinkler systems design
NBC 2016
National Building Code (latest)
ASHRAE 62.1
Ventilation for acceptable IAQ
IEC 60364
Low voltage electrical installations
NFPA 13
Sprinkler systems installation
Always Verify Code Version

MEPMate may not immediately reflect the latest revisions to standards. Users are responsible for verifying that calculations comply with the currently applicable version of all relevant codes and standards in their jurisdiction. When in doubt, refer directly to the published standard from BIS, NBC, ASHRAE, or the relevant body.

🚫 No Warranty on Results

MEPMate provides its calculators and all results "as is" and "as available", without any warranty of any kind, express or implied, including but not limited to:

  • Warranties of merchantability or fitness for a particular purpose.
  • Warranties that results are accurate, complete, reliable, or error-free.
  • Warranties that the platform will be uninterrupted or free of errors.
  • Warranties that defects will be corrected.

MEPMate has made every reasonable effort to ensure the accuracy of its calculation algorithms. However, we acknowledge that:

  • Numerical methods involve rounding and approximation errors.
  • Some calculators use simplified models that do not capture all real-world variables.
  • Input values are provided by the user — garbage in, garbage out.
  • Software bugs may exist despite our testing efforts.
Limitation of Liability

MEPMate shall not be liable for any loss, damage, injury, or expense of any nature whatsoever arising from the use of or reliance on calculator results — including but not limited to structural failure, fire, flooding, electrical hazards, or financial loss.

🐛 Reporting Errors

We actively encourage users to report suspected errors in our calculators. If you believe a result is incorrect, please:

  • Note the calculator name and the specific inputs used.
  • Describe the expected result and reference the relevant code clause.
  • Email your report to bugs@mepmate.com or use our contact form.

We investigate all reports and update calculators promptly when errors are confirmed. We are grateful to the engineering community for helping us maintain accuracy.
