P Cullen’s remarkable resourcefulness and commitment to safety has earned the company well-deserved recognition by SEAA, who selected the Milwaukee Bucks Arena as Class IV Project of the Year. There were just 290 days between setting the first piece of steel and the topping off celebration, which marked the conclusion of an extraordinary accomplishment by the JP Cullen team.

If the anemometer on the crane measured wind speeds exceeding 30 miles per hour, lifting of the roof trusses had to be stopped until it fell below the threshold. The inability to control Mother Nature made it even more imperative to carefully orchestrate operations and support the timely achievement of project milestones. Since most of the structure was steel framed, steel fabrication and delivery was the critical path for all other follow-on activities and creating a reliable schedule to supply the material
