Aggregate Technologies award-winning precast removal expertise was displayed at the Houston Museum of Fine Arts recently with the removal of 70 tilt-wall panels, ranging from 3.5 to 8 tons in weight. With the limited work space, all sections had to be picked and hauled away from the job site. Another difficulty was the embed plates that held the panels were behind a concrete curb that was 12″ high and 8″ thick. Extreme care had to be taken with this part of the job to not damage the existing post tension slab that held the embed plates.
Another part of the job was concrete sawing to the correct height 13 concrete columns that were 20′ high and 2′ x 2′ square. Each column had to be cut clean and flush so the contractor could install the new steel structure on the top of it.
In another area the ATI team concrete sawed the elevator roof structure – while the elevator was still in use. The roof section was a 20′ x 25′ section about 20′ high. They had to remove the exterior walls so the contractor would have access to the inside. When removing the wall operators had to take special care to not let any debris fall to the inside. Further complicating this part of the job was picking the wall section out and removing it.
To do this they core drilled lifting holes so a forklift could hold and pick out each section of wall. Once the walls were gone the contractor installed scaffolding and waterproofing under roof structure so we could begin the roof demo. As in the other part of this job, they had to remove all debris while cutting with no staging on site.
