New Jack Trice Stadium Scoreboard a Triumph of BIM, Team Collaboration
Posted by Tasha Weiss on December 12, 2012 at 7:02 PM.

Last summer, a new 36-ft-tall, 80-ft-wide video/scoreboard was installed on the north end of Jack Trice Stadium, home of the Iowa State Cyclones. It is one of the 15 largest scoreboards used in a college football stadium.

 

The steel structure supporting the board spans more than 150 ft and was erected overtop an existing two-story building. To minimize interruptions to the Iowa State Athletic Department, the construction team built the entire horizontal structure on the ground and then erected it over the existing building. Once the structure was assembled and the vertical towers were in place, the team hoisted the larger truss.       

 

The construction team included general contractor Weitz Construction, Des Moines; Weitz Construction Product Distributors, Des Moines; Northwest Erectors, Grimes, Iowa (an AISC member/AISC advanced certified erector); HR Steel Detailing, Kearney, Mo.; and Raker Rhodes Engineering, Des Moines. The team used 3D modeling extensively to coordinate the difficult schedule and steel erection. Daktronics, Inc., of Brookings, S.D., supplied and installed the video board.

 

Raker Rhodes Engineering (RRE) was given a preliminary structural analysis model from Daktronics. The challenge was to reduce the project tonnage in order to facilitate the tricky crane pick over the existing building. RRE accomplished their goal of reducing the steel tonnage and used the analysis model as the basis for their Revit model. They then shared the model with the steel detailer, who added connection material using SDS/2 detailing software, then created 3D PDFs of the detailed model for team members to use for coordination. A 3D sketchup model, created from the RRE Revit model, was inserted into Google Earth to give the owner an idea of the scale and final location of the scoreboard structure.
