Mammoet wins Rigging Job of the Year award
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 to $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 centimeters of tolerance for a precise fit, the bridge span was carefully hoisted into its final position, 22m (72 ft.) from the ground, before being welded into place.
After nearly eight years of planning, design, and construction, the installation has created, at 274m (900 ft.) long, the world's longest pedestrian bridge span over an active airport taxi lane. In 2020, Mammoet's team completed the installation of the first airside bridge in Hong Kong as well. The international arrivals facility is currently open and in use. Alongside other improvements planned for the airport, the walkway will help double the airport's international passenger capacity to 2,600 per hour.
