This diagram compares the BOMA 1996 Office Standard against the new BOMA 2010 Office Standard. At first glance one immediately assumes that the new standard "grows" the building. Actually, total building rentable SF does not change between the two standards, except for garden style office buildings with exterior circulation. Exterior (unenclosed walkways) Circulation is included in rentable as building service for the new 2010 Standard.

The diagram also shows the relationship of the BOMA Gross Area Standard to the 2010 Office Standard. If you would like further clarification on the new standards give us a call.

BOMA Office and Gross Area Measurement Standards Recieve ANSI ACCREDITATION

On May 26, 2010, BOMA International announced that two more of its measurement standards recieved accreditation from the American National Standards Institute (ANSI).

Office Buildings: Standard Methods of Measurement (ANSI/BOMA Z65.1-2010) is a new Standard and update to the 1996 Office Standard. The 2010 Standard includes improvements over the 1996 Standard including a new "Single or Average Load Factor Calculation" (Method B), Extended Corridors, Base Building Circulation, External Circulation, and additional diagrams, definitions, and explanations.

Gross Areas of a Building: Standard Methods of Measurement (ANSI/BOMA Z65.1-2010) is a new Standard primary used to calculate Construction Gross and External Gross Areas of a building. The Standard is applicable to all types of buildings, Office, Retail, Industrial, Hospitality, Medical, etc.

Construction Gross area can be used for insurance purposes and replacement cost as well as other applications.

External Gross Area may be used to determine a lease rate when leasing to a single occupant or tenant in a building.

BOMA is also close to finalizing two additional standards, Multi-unit Residential Buildings and Retail Buildings. Click to learn more about BOMA Standards.


BOMA Webinar - New Office Building Measurement Standard

On Tuesday, March 16th, BOMA International formally announced via email a new webinar aimed at understanding its latest Floor Area Measurement Standard for Office Buildings.


Kent Gibson, the current Secretary/Treasurer for BOMA International and former Chair of the Standard Floor Measurement Committee, will be conducting the webinar. The new 2010 Office Standard is a significant revision of the 1996 Standard and includes expanded definitions, 45 full color illustrations and is presented in a digital hyperlinked PDF format.


In the Webinar Kent plans to review the 1996 Office Standard, outline some of the significant and new features of the 2010 Standard including "Single Load Factors", occupant storage and external circulation for buildings located in sun belt areas. The new Gross Area Measurement Standard will also be reviewed which is used to calculate construction and exterior gross areas.


The Webinar will be conducted on Tuesday, April 6th from 2-3 PM Eastern Time. A $125.00 registration fee is required for BOMA members and $175.00 for non-members. Webinar registrants will recieve a promotion code for a 20% discount on purchasing a Standard.

The BOMA Standard / Method of Measurement - 3 Step Process

We often hear the question, "Has the building or suite been measured per BOMA?" A more appropriate question should be, "Has the BOMA process been followed precisely and correctly documented when measuring to yield a BOMA Office Standard RENTABLE area?"

A building measured to the BOMA Standard means that an exact, sequential method was followed when measuring the building. This method is comprised of three different steps.

How & Where to Measure
The first step defines the sequential process of how to measure a building. For example, first,establish the Interior Gross Area (IGA) and so on. If the specific order of measurement is changed the final calculation will be incorrect. The Standard also defines where the boundaries of the measured space are established.

For example, the inside face of the dominant portion (glass or wall) of a vertical exterior enclosure defines the boundary. Again, if the rules of boundaries are not followed significant discrepancies will occur in final calculations.

Inventory & Categorize
The next step is to identify and inventory a complete list of all measured rooms and areas within the building. Categories may include lobbies, corridors, restrooms, occupant area, mechanical, elevator, electrical, shafts, etc. Incidentally, there are some areas of a building that the BOMA Standard does not recognize or measure. It is our practice at Stevenson to measure all parts, areas, patios, walkways, overhangs, etc. that go with the building. These areas typically are not included in the calculation but many commercial real estate professionals want a complete inventory of the entire building.

Apportionment & Calculation
The third step is to apportion all inventoried areas to their respectful classification of space. BOMA clearly identifies the classes including, major vertical penetrations, occupant areas, building and floor services areas, etc. The Standard also identifies where the boundaries of each class of space is located (wall priority diagram). Finally once all areas have been classified a series of calculations and formulas are applied to determine Rentable, Service, Amenity, and Usable square feet. A formula is also applied to obtain a load factor.

As tenants move in and out of a building measurement becomes increasingly sophisticated. Maintaining correct building calculations requires diligent and expert documentation by an experienced Space Accounting firm.


BOMA 2010 Winter Meeting

During the annual BOMA Winter Business Meeting held last week in Washington DC, the Floor Measurement Standards Committee met to discuss the recent release of the new 2010 Office Standard, committee progress being made on the new retail and multi-residential standards and ANSI Accreditation.


Committee members present included Building Area Measurement LLC, American Building Calculations, Stevenson Systems, Colliers Arnold, 2D As-Built Floor Plans, PREIT Services, LLC, Matrix Development & BOMA International.


Throughout the years as the Standards have evolved the Floor Measurement Committee has revised and introduced concepts, explanations, clarifications, illustrations and definitions that have shaped and become part of the known Standards today.


The Committee is comprised of many real estate professionals who have donated their time and talents to provide better measurement standards that are practical and work in multiple real life situations remaining relevant over time as occupancy and building configurations change.


The BOMA Office Standard last revised in 1996 has now become a collection of measurement standards to handle the complexities of calculating square feet in a variety of building types, uses and structure. As of today this includes 2009 Gross Area, reaffirmed 2004 Industrial and 2010 Office Standards.


The 2010 Retail and Multi-residential Standards have been committee approved and await publication upon final approval. It is anticipated that the adoption of these two new Standards will be wide spread due to the lack of a national standard in either product type.


In the wings remain the Multi-use and Complex Standards that may get committee approval within the next year.


In the past BOMA International has sought the accreditation of its measurement standards from the American National Standards Institute (ANSI). ANSI accreditation signifies that the procedures used by standards developing organizations, such as BOMA, meet the Institutes requirements for openness, balance, consensus, and due process.


Currently none of the BOMA Standards are ANSI accredited when the 1996 Office Standard expired in 2006. BOMA is currently pursuing accreditation for the reaffirmed 2004 Industrial Standard and when approved they will seek approval for the 2009 Gross Area and 2010 Office Standard. BOMA is hopeful that it will receive its accreditation of these Standards by the end of 2010.


The Measurement Committee will reconvene in June at the BOMA Summer meeting held in Long Beach, CA.
