The AIA Standard
AIA Document D101, "Methods of Calculating Areas and Volumes of Buildings" has been the standard "in the trade" for Architectural Area, which is the basis for all the construction square foot costs cited in publications used by architects and estimators in projecting building construction costs. The current version is the 1995 edition. It can be obtained through local chapters of the American Institute of Architects and some other authorized re-sellers. They are sold in packets of three at a cost of $4.20 for AIA Members and $6.00 for everyone else. A copy is included in the AIA Handbook of Professional Practice. An older (1980) version of it is also published on page 1,007 of the tenth edition of Architectural Graphic Standards, a reference that is widely used by architects.This simple 2-page document is a good reference if a Gross or Construction area is required, which is often the case in figuring the replacement cost of a building. Short as it is, it does a much better job of defining Gross area than the BOMA Standard. It also contains definitions for Architectural Volume, Office Assignable Areas, Retail Assignable Areas and Living Areas. It includes simplistic definitions of Rentable and Usable areas that are almost never used in leasing space because the BOMA, GWCAR and RENBY standards are far more complete and widely accepted. |
