Glossary Term Defined

The difference between two area calculations of a suite, floor or building area made by two individuals. The area calculation of a building owner is deemed accurate if the variance between their area calculation and that of another party is less than 2% . 

It is common for a floor area calculated from the building plans (paper plans or CAD) to differ from the floor area measured on site using field measurements. It is also common for the field measurement and calculation of floor area by one party to differ from the same field measurement and calculation by another party. The calculation of a floor area, resulting from field measurement by the building owner or manager, is deemed accurate if a re-measurement gives results with variance of two percent (2%) or less. If the variance is greater than two percent (2%), BOMA International recommends that an unbiased professional third party be sought to assist in resolving the matter.
