Des Moines is a rapidly growing major metro in the Midwest U.S. One new addition to its skyline is the construction of a new 12-story parking structure.
Construction of this new parking garage is currently in full swing. Located between Walnut and Court Avenues along 5th Avenue in downtown Des Moines, Iowa, the garage, a post-tension concrete structure, will measure 300,570 square feet and will accommodate 750 new parking stalls and street-level retail spaces. The garage will provide the community with daily and monthly rental options and entertainment parking. Operationally, the parking controls guiding vehicle entry and exiting are being designed to provide the best user experience possible. The Fifth parking garage will have an open concept on the east elevation with a decorative screening element on the west elevation. Final completion is expected in July 2020.
DBM Vircon was awarded the coveted 2019 North America Tekla BIM Award in Cast-in-Place category for its modeling work using Tekla on this project.
DBM Vircon team detailed this project in 3D using Tekla software. Modeling of parking garages is inherently bit complex because of varying elevations of the ramps and the different height of walls and columns supporting these ramps. Considering the complex foundations, slab-on-grade, and post-tension structure assemblies on this project, the model had to be precise to identify trade clashes and varying elevations of supporting elements (i.e. columns and walls) to prevent field errors. The utilization of Tekla 3D modeling software made it possible to identify and visualize constraints that were then communicated to the structural engineer. In conjunction with weekly work plan meetings, Tekla 3D modeling also proved valuable in managing design changes and resolving issues that could have otherwise delayed over 700 tons of rebar. So far, DBM Vircon rebar model has generated over 70 RFIs for engineer’s review and resolution, which helped identify and solve several construction conflicts which otherwise would have been discovered at the site and caused delays in project completion.
