HOK Automates BIM deliverables for Salt Lake City terminal redevelopment
hat project managers need to know is that automating the BIM documentation process is going to save time and money, says HOK Design Technology Specialist, Shaun Peppers.
Scheduled to open in 2020, the new $1.8 billion, 1.7 million sqft, three-story Salt Lake City Airport terminal designed by HOK will accommodate 23 million passengers per year. It is one of the largest construction projects in North America. “Sharing all the documentation and data across the vast amount of offices involved is tricky to say the least. Currently the SLC project is exporting upward of 4700 virtual PDF prints weekly. We were also exporting 51 Navisworks NWC files from the Revit models twice-weekly for clash detection and daily AutoCAD exports for civil coordination,” says Shaun.
“The larger models take half an hour to open, then an hour and a half to manually print 300 sheets over 30 link models in Revit. If you multiply that by ten people trying to print all these sheets every week then you’re looking at thousands of hours over the project. “There was also no way to control the quality of the prints because we were getting different formats from different people. It was like the ‘telephone game’ by the time it had filtered across everyone.” RTV Tools’ Xporter PRO is an add on for Revit that automates documentation processes, allowing users to schedule prints to two physical printers while simultaneously creating digital files such as DWG, DWF, PDF, IFC and Navisworks, all unattended.
“In the early stages of design, printing was done manually across all disciplines. Documents could take weeks to get to everyone who needed the information, by which time the models had progressed and so the static data would become out of sync with the current design.
The data needed to be streamlined and up to date at all times to prevent log jams. - Shaun Peppers
