Glazing Contractors: "Most Recent Edition" No Longer works

As the American Institute of Architects (AIA) nears the end of its ten-year revision cycle for revising its A201 and A401 documents, glazing subcontractors should pay close attention to how contracts-whether their own or their customers'-read when referencing these two documents, reports the American Subcontractors Association (ASA). AIA A201 is the General Conditions of the Contract for Construction and AIA A401 is the Standard Form of Agreement Between Contractor and Subcontractor. Once the new documents are published, ASA said accurate information and references will be critical since both the 1997 and 2007 versions will be in use at the same time.

A contractual reference, for example, to "the most recent edition" of one of these AIA documents, or a reference that does not specify the year of the edition, could leave a glazing contractor working under conditions different than originally expected.

Glazing contractors can prepare for these changes by being specific about which editions of these AIA documents are being used and also asking for clarifications in writing if there is any uncertainty.
