The Construction Industry Affairs Committee of Chicago (CIAC) in cooperation with the Chicago Chapter of the American Institute of Architects (AIA) is sponsoring Recommendation 18, titled "Substantial Completion." As it applies to a contractor-owner agreement for a construction project, substantial completion is a most misleading term, according to Edward W. Olson, Sharman of CIAC, who also represents the Chicago Chapter of AIA. Through the efforts of the entire CIAC in Chicago, however, it has been possible to expand on the meaning of "substantial completion" and provide suggestions on how to apply it to specific contracts. The complete text of the CIAC's Recommendation 18 was written to clarify the original AIA paragraphs. The Recommendation stresses that a successful owner-contractor agreement should contain clear statements of the responsibilities of both parties with respect to maintenance, heat, utilities and insurance, as well as decisions concerning guarantees and warranties, and how the retention is to be handled until final completion. Rather than deciding on terms for acceptance in a Certificate of Substantial Completion at the close of a project, the author believes that the owner-contractor agreement for the construction work should establish the proper coarse to follow once a project has been certified by the architect as "substantially complete" and the responsibilities of both parties with respect to maintenance, heat, utilities and insurance should also be included in the agreement, as well as decisions concerning warranties and guarantees and the formula for determining the amount of retention to be withheld until final completion. If any of these decisions are delayed until the Certificate of Substantial Completion, they could be unacceptable to either or both parties. Actually, the only matters that cannot be incorporated in the agreement are the actual dates of substantial and final completion, the punch list items and the time and cost to finally complete the remaining work satisfactorily.
