Quick Start Guide

Before starting your cost estimation, gather the following information:

  • Project name and location details
  • Building specifications and dimensions
  • Material and finish preferences
  • Special requirements (HVAC, fire protection, etc.)

Important Notes

Common Mistakes to Avoid

Unit conversions
Use meters, not mm

Heights like 2700 should be 2.7 m.

Built-up area
Exclude parking & yards

Count only the actual building footprint you’re estimating.

HVAC overload
Match systems to use

Avoid heavy HVAC on small homes unless it’s truly required.

Mixed quality
Keep tiers aligned

Mismatched fixture/finish grades skew the whole BOQ.
