Earlier this month, we reached a major milestone at our Confidential Testing Facility. This project is one of the most technically demanding we have had to date. This project involved the lift and placement of a 251,000-pound pre-poured concrete roof slab at the facility. To achieve this lift we focused on thorough planning and stayed in constant communication with our trade partners.

To position a precast slab within just 1/8 of an inch in every direction, including elevation, our team leaned on months of strategic planning and coordination to make sure everything went smoothly in the field. Using a Davis 925T crane and precise laser alignment based on a single reference point inside the structure, we were able to put our detailed preconstruction models into action on site.

What set this lift apart was the sheer technical challenge. Setting such a massive slab within a tolerance as tight as 1/16” to 1/8” not only required advanced equipment, but also strategic teamwork and communication. The collaboration between our preconstruction and field teams, Davis Crane Company, United Mechanical, Alamo Steel, Deem Erectors, MDS Aero, and our design partners at Calahan and Freeman Architects and Stubbs Engineering was key to making it all come together.
