All CAD drawings and space calculations are rendered to BOMA (Building Owners and Managers Association) standards or standards of your choice. Our professional field measurers show up on time and gather data quickly using the latest lasers accurate measurement technology. Our Disto brand lasers are accurate up to 300 feet +/- 1/8”. We are experienced in industry accepted standards used locally in the Commercial Real Estate markets for Commercial, Governmental & Institutional, Industrial /Manufacturing, Retail, Medical, Condo, and Residential properties.

BOMA Standard for Office Buildings (ANSI-BOMA Z65.1) This standard is used to calculate the Useable and Rentable square footage in standard multi-story office buildings. It dictates that areas are calculated to the inside surface of the exterior walls and to the glass line where applicable. Calculation of building and floor common areas are specifically adhered to, based on these standards. This is the main set of standards that all others are based on.

BOMA Standards for Industrial Buildings (BOMA/SIOR 2004) – This standard contains two methods for calculating floor areas of Industrial Buildings and which standard to use is voluntary and guided by the dominant market practices of the area.

THE EXTERIOR WALL METHODOLOGY (METHOD “A”)
The area is calculated including the exterior walls as rentable area. Calculation of building and floor common areas are done the same way as ANSI-BOMA Z65.1. This method is used widely in our area for many types of buildings: Industrial/Flex, Retail, Condo and Residential. Some single story office and medical use this standard as well.

THE DRIP LINE METHODOLOGY (METHOD “B”)
The area is calculated including exterior walls and all the way to the drip line of the building which will include some area outside the building. This method is rarely used in our area, but some of clients have requested this method based on company standards.

Regardless of which standard our clients choose to use, we will render your calculations accurately and note them prominently on your drawings. It is our policy NEVER to put false square footage calculations on any drawing bearing our logo. When you see the Dimensions Floorplans logo on a drawing-you know it is correct.
