The current  \ntrend may have started with Helmut Jahn’s United Airlines Terminal in Chicago, but it has now spread to everything from small retail stores to office lobbies.  \nUnfortunately, existing codes and standards—even AISC’s Code of Standard Practice—do not fully address the unique level of detail needed to successfully design, detail, fabricate and erect Architecturally Exposed Structural Steel (AESS) . Further, because AESS costs more to fabricate than standard structural steel, it is critical that these designs are properly budgeted. The repercussion of not properly budgetingAESS is often the need for redesign, project delays, and ultimately even higher project costs. In addition, the members requiring special handling and finish are often poorly identified in the contract documents—and, since the EOR often specifies the steel while the architect specifies the paint and appearance, there is sometimes a built-in conflict or compatibility issue. Finally, the lack of acceptance criteria for AESS members often leads to disputes between the design team and the contractor over what is desired versus what was bid.  \nIn response to these issues, the Steel Liaison Committee of the Structural Engineers Association of Colorado and the Rocky Mountain Steel Construction Association, with input from local contractors and architects, developed guidelines to assist in the specification of AESS. According to the Committee: “The goal of these tools is to allow the designer to communicate the desired appearance in a format that Contractors can price/budget/bid more appropriately.”  \nThe guidelines include three key elements:  \nSample Board: The sample board includes small pieces of fabricated structural steel that indicate a range of finish surfaces that can be expected from structural steel fabricators. The board includes bare steel with fabrication “defects”and pieces with typical finish coats. The samples are intended to allow the designer to see how various fabrication techniques affect the final product. The goal of the sample board is to allow the designer to decide what features are important for their project. Physical samples allow the designer to evaluate how imperfections in the finished surface appear from various distances.  \nThe photos printed here are taken from the sample board , but due to reproduction technology might not fully represent the actual appearance on the sample board. However, design-  \ners or contractors wishing to obtain an actual sample board can purchase one from Zimkor Industries for $1,780 by con[tacting William Zimmerman at wgzimmerman@zimkor.com](tacting William Zimmerman at wgzimmerman@zimkor.com)[ ](tacting William Zimmerman at wgzimmerman@zimkor.com)[or 303.791.1333](or 303.791.1333).  \nCost Matrix: Of course, knowing appearance of the final steel is only half the story. Equally important is knowing the budget impact of AESS. The cost matrix is designed to provide the designer with the cost premium associated with specifying the desired techniques to achieve the final appearance of an AESS project. The cost of producing work toa higher appearance standard varies greatly from fabricatorto fabricator, depending on the equipment in the shop and the experience of the staff. This variation is indicated in the cost matrix as a range of cost premiums for each desired fabrication technique or finish coat item specified.  \nThe cost premiums noted apply to the total weight of AESS for that particular line item, fabricated and erected. While the cost matrix was prepared initially by surveying fabricators in the Rocky Mountain region, the figures have been further checked through surveying a select group of national fabricators. The idea behind the cost matrix is to allow a ","cbCaio7WCl1qnn3q","https://ap.wps.com/l/cbCaio7WCl1qnn3q","pdf",241732,16,"English","# Sample Board\n# Cost Matrix\n# Specification","[{\"question\":\"Why is budgeting critical when specifying AESS?\",\"answer\":\"AESS typically costs more to fabricate than standard structural steel.
