Phoenix International Raceway Grandstand and Midway Project Highlights & Challenges:

The detailing aspect of the project was completed within a 5 month period. This project contained liquidated damages on the contract due to the schedule demands imposed by the owners.

Consequently, the detailing was likewise awarded to two detailing firms resulting in a constant coordination effort between the two firms to match and interface connections where the scope intersected.

Coordination models between the two firms were regularly exchanged to ensure that interface connections and steel location matches.

Connection design was provided by two design teams as well, resulting in a situation where connections by both teams were being incorporated by DBM Vircon in its scope.

Red metal wall panel 3D IFC model and coordination drawings were provided by the client since no usable information was given on the design drawings to complete the wide flange red wall panel supports and connections to the main member.
