Sometimes a little out of the box thinking and thoughtful engineering are just what the project needs.
The shear wall was picked using a 10,000 lb forklift. An engineered cut and pickhole design were part of the pre-task planning for this work.
During construction, Tees were held into place using traditional construction methods. After sawcutting and cabling, Tees had to be dislodged from the remaining structure.
The location of some Tees did not allow for direct cabling and access by the tower crane, so solutions were created to cut and move the pieces into place for removal.
Removing the roof structure on this 7mg tank was done with a trackhoe with a shear attachment. Tank removed and hauled off in 4 weeks, start to finish.
This project was a large-scale operation to open up large areas of building for vertical transportation. All floors had to be completely shored to maintain structural integrity during the cutting and removal operations. 150 towers per floor, specifically.
Tees were cut and lifted from as deep as six stories into the building, over the roof and into waiting trucks.
