Idaho Hospital Bids Farewell to ‘Sheila’, Sets Skybridge By Lori Tobias
St. Luke’s Children’s Hospital photo
CEG CORRESPONDENT
A towering feature on the Boise, Idaho, skyline is disappearing, its job done after more than a year on site. Dubbed “Sheila” by project manager Jamal Nelson, the 175-ft.tall Linden Comansa 2100 tower crane played a critical role in the construction of the new Idaho Elk’s Children’s Pavilion since its erection in June 2017. In late October, two assist cranes — a Liebherr 1300 360-ton and a Terex T780 80-ton — arrived at the hospital site to dismantle the tower crane and move it off site. “They took her apart in chunks,” Nelson said. “They made a connection to the assist, unbolt the jib and took out the counter weights and took her apart from top down. There was a select crew of three or four guys who did the dismantle and unrigging. They dropped large pieces down and they get broken

down into smaller pieces. Then they go to crane suppliers’ lot and did all the regular maintenance and recertifications. When they dismantled her, they went back through every single part of her and made sure she is top notch operating condition before she gets reassigned.” While on the job, the tower crane was used for numerous aspects of the project from the underground up, Nelson said. “There’s two things about tower cranes. Sort of like the left and right brain. There’s the functional physical tool, it’s raising and lowering materials to a place that are difficult to reach. With that tool we went 30 feet underground and built a parking structure, lowering all the equipment and materials into the hole. And then all the stuff we had to pull out. Once you go vertical, hang steel going up, concrete buckets, all your material coming see SKYWALK page 4
WSDOT Plans for Alaskan Way Viaduct Closure, Beyond The start of the new year signals dramatic changes ahead for Seattle drivers and commuters. On Jan. 11, 2019, the Alaskan Way Viaduct permanently closed to start three weeks of work needed to open the new State Route 99 tunnel. When the new SR 99 tunnel opens in early February, getting to and from Seattle via SR 99 will be a very different experience than it is today. The tunnel is a direct, 2-mi. trip underneath downtown Seattle. Tunnel entrances and exits, near Seattle’s Space Needle to the north and the stadiums to the south, work differently than the entrances and exits on the viaduct.
The Washington State Department of Transportation produced four new videos to help drivers navigate the changes the new tunnel brings. The videos show: • Driving north to and through Seattle with the new SR 99 tunnel; • Driving south to and through Seattle with the new SR 99 tunnel; • Getting to northbound 99 from in and around Seattle with the new SR 99 tunnel; and • Getting to southbound SR 99 from in and around Seattle with the new SR 99 tunnel. The tunnel will be free to use when it first see TUNNEL page 6
After the tunnel opens, it could take weeks or months for traffic patterns to settle down as drivers try different routes to and from their destinations.
