After six months of detailed planning and intense coordination, our Philadelphia International Airport team last month erected a 91,000-pound, 100-foot-long pre-assembled baggage conveyor bridge over the main airport departure road in less than eight hours. While this was a very complicated activity, our team got it done smoothly, and even four days ahead of the original schedule for this milestone event.
To ensure that nothing would hamper the erection, our team had a variety of contingency plans in place. For example, while extensive surveys had been done to ensure that the anchor bolts on the bridge piers would match with the holes on the pre-assembled bridge, temperature changes and flexing caused by the lifting could have slightly varied the geometry. So before the lift, our team developed a procedure for field repairs that the structural engineer approved.
Also, this task done overnight at the airport required closing the departures road, but if an airport emergency occurred, emergency response vehicles might have needed to go beyond the construction area. So they built a temporary blacktop road for that use.
“This was truly a collaborative effort involving the airlines, Division of Aviation, airport operations, Philadelphia airport police, PennDOT, the construction manager, trade contractors, the design team and Inspectors,” said Brian Maguire, project director. “Thank you to everyone who helped make this event a tremendous success!”
This lift is part of a $44 million lump sum general contract we have with client US Airways. Our work also includes building a 35,000-square-foot bag-claim facility and 40,000 square feet of phased renovations to Terminal F and an adjacent connector.
