BOMA 2017 Updates – “Standard Methods of Floor Measurement”


Initially developed in 1915 with an “Office Measurement Standard”, the Building Owners and Managers Association (BOMA) has continued over time to establish a uniform industry process model to measure spaces within a variety of building designs and tenant amenities. Architects, Interior Designers, Building Owners, Appraisers, Contractors, Brokers and many other professionals benefit from these BOMA consistent benchmarking tools to establish value and communicate a common language in measuring the complex diagnostic of building floor areas.

So, What’s New?

Since 1915 BOMA has upgraded its tool box over the years, most recently 1996, 2010 and now, the 2017 version. The data generating framework of the 2017 update still relies on the 2010 issuance of two independent Method choices, (A&B), of calculating floor measurement. Method A generates multiple “Load Factors” for a series of space types applied to Occupant Areas. Method B consolidates all shared spaces together to catalogue as one “Load Factor” for the overall building, which is then applied to Occupant Areas. Only one Method or the other can be used for a building analysis. The final product is what BOMA calls its spread sheet, the “Global Summary of Areas”.

The modifications from the 2010 version to 2017, involve input nuances together with classification refinements reflecting changes in contemporary building designs and boundary conditions of tenant amenities, temperate climate external circulations, rooftop decks, balconies and mezzanines, for example.

The 2017 iterative sequential data input process requires following a five (5) step method:

1) Measure the Interior Gross Area (IGA).

2) Establish the IGA Boundary and classify all spaces.

3) For each class of space, determine boundary lines.

4) Calculate the areas of all classes of space (Global Summary of Areas calculates rentable areas).

5) Disclose certain areas which may or may not be valuable.

Without getting into the actual nitty gritty details of producing 2017 Global Work Sheets, it is worth an overview to list the nine (9) GA Boundary Conditions for an understanding of how tightly controlled the data is for reliability and common clarity among Designers, Brokers and Tenants.

1)-Vertical exterior enclosure; 2)-Public pedestrian thoroughfare; 3)-External Circulation; 4)-Non- vertical exterior enclosures; 5)-No dominant portion; 6)-Unprotected exterior opening; 7)-IGA adjacent to a void with a full or partial wall; 8)-IGA adjacent to a void without a wall; 9)- Ownership change inside the Building Connector.

Lessons Learned:

1-This is a very brief overview of BOMA’s 2017 standards/concepts and does not attempt to instruct or educate beyond these general points made. To properly undertake a 2017 “Standard Method of Floor Measurement” process for any building, it is absolutely recommended that a Space Measurement Professional be consulted.

2-The issuance of any lease, contract for sale/purchase, etc. should stipulate which Method, (A or B) was utilized in preparing the data relied upon for the transaction.
