On Friday October 29, Mammoet’s USA team won a Job of the Year award at the Specialized Carriers and Rigging Association’s (SC&RA) Annual Conference in San Antonio, Texas. The award was for Rigging Job of the Year in the $750,000-$2 million (US) project category.
The purpose of the SC&RA awards is to give special recognition to members that perform exceptional achievements in solving problems encountered in rigging and hauling.
Mammoet presented the successful completion of the transport and lift of Seattle-Tacoma International Airport’s newest expansion - an elevated pedestrian walkway for the future international arrivals facility. Part of the airport’s $968 million expansion, the new bridge is only the second walkway in the world with suitable clearance for a Boeing 747 to taxi beneath.
Once transported into position under the existing V-piers, erection crews used four 816t (900 US-ton) steel frames that utilized a strand jack system. This was the first time these frames, from the Netherlands, had been used in the United States. With just a few centimetres of tolerance for a precise fit, the bridge span was carefully hoisted into its final position, 22m from the ground, before being welded into place.
After nearly eight years of planning, design, and construction, the installation has created, at 274m long, the world’s longest pedestrian bridge span over an active airport taxi lane.
Mammoet vice president, Anthony Garcia, said: “Mammoet is tremendously proud to win this award and to be recognized by the industry for such an innovative project. This would not have been possible without our team’s dedication to excellence, and I would like to thank them for all their hard work.”
