Wausau Window and Wall Systems: Company Adds All-Inclusive, User-Friendly Curtainwall Revit Model
Jan. 26, 2016 — Wausau Window and Wall Systems is significantly expanding its 3-D building information modeling (BIM) tools with the addition of a new unitized curtainwall Revit project file.
This single file is pre-loaded with Wausau’s INvision family of unitized curtainwall profiles, allowing architects, designers, engineers, and contractors to easily choose different widths, depths, and sightlines. This all-in-one approach automatically updates to the selected parameters without repeating steps or requiring multiple files.
“Our all-inclusive approach saves time by making the whole process much more simple for the user to explore multiple options and determine the right conceptual fit without needing to open, create, and recreate multiple files,” said Jerry Habeck, Wausau’s product standards manager. “You can change the curtainwall model on the fly to see how our curtainwall looks on your building design, and then change it again as you choose.”
Steve Carrico, Wausau’s design engineer, said, “Because it’s all very visual, building owners and team members also can use our Revit files in conjunction with other BIM tools for clash detection. This not only can help save headaches, but can save money by identifying potential conflicts on the drawing board before anything is fabricated and shipped to the field.”
Carrico added, “Clash detection functionality can be especially useful in design of hospital patient room plenum areas, which contain curtainwall anchor assemblies, spandrel beams, fire safing, and dampered return ducts, as well as medical gas and communications lines — all competing for the same physical space.”
Projects of high geometric complexity are also prime targets for the application of BIM tools. On California’s award-winning Anaheim Regional Transportation Intermodal Center (ARTIC), the architect, HOK’s Kazem Toossi noted, “BIM was an important tool to set out the compound curve on east and west walls where Wausau’s window walls and metal panels were utilized. These elements were supported off of the supplemental steel framing from the building structure.”
According to “SmartMarket Brief: BIM Advancements No. 1,” a new report released by Dodge Data & Analytics in Deccember 2015 based on surveys from more than 300 BIM users:
• 48 percent see a 5 percent decrease or more in final construction cost
• 51 percent have a 5 percent reduction in their project schedules
• 31 percent also have a 25 percent improvement in labor productivity
The SmartMarket Brief’s research report also revealed that the building envelope is among “the greatest areas of unmet demand” for building modeling tools. Wausau’s Habeck and Carrico agreed. They found few examples across the industry and much room for improvement. “We really wanted to deliver the most user-friendly, best-in-class 3-D model we could. And I think we succeeded,” Habeck said.
All Wausau Revit files were developed in compliance with the requirements for design intent models included in the American Architectural Manufacturers Association’s (AAMA) 913-14 “Voluntary Specification for Non-Residential Fenestration Building Information Modeling (BIM).”
Unitized curtainwall systems like INvision are factory-assembled and glazed under controlled conditions before shipment to the job site. Only one unit-to-unit splice (usually a silicone sheet or patch) needs to be field-sealed, and only one anchor per mullion needs to be attached to the face or top of the floor slab. These features minimize dependence on scarce and expensive field labor. Interlocking unitized curtainwall frame members are weather-stripped to seal to one another, both horizontally and vertically, accommodating building movements.
