Staged Demolition Planning and Structural Assessment
The complexity and scale of this structure required a meticulous approach to ensure both safety and efficiency during the Staged Demolition. Due to the absence of original design drawings, our team began with a detailed inspection of the debarking building. This included precise measurements and structural assessments, which allowed us to develop a 3D model. That model became the cornerstone of our demolition plan, enabling each stage to be mapped with confidence. Understanding the behavior of the steel and concrete elements was essential to a safe and incident-free execution.
On-Site Engineering and Controlled Removal
One of the project’s major challenges was removing the large steel structure. Our engineers planned for torch crews to cut the steel into the largest manageable sections. They coordinated closely with the demolition team, as the crane had limited reach and capacity. To overcome these limits, Arch provided on-site engineering support and ensured each lift followed the prescribed sequence and safety plan.
The cast-in-place concrete slab roof presented a different challenge. It had to be saw-cut and lifted out by crane—without allowing pieces to fall onto the platform below. This called for precise cuts and a coordinated lifting strategy that protected the remaining structure from damage.
Throughout the Staged Demolition, we maintained a dynamic and adaptive approach. By working closely with the contractor and providing daily field updates, we kept the project aligned with the schedule. Our ability to respond quickly and communicate clearly helped ensure the safe, efficient removal of the structure—solidifying Arch’s role as a trusted partner in complex demolition projects.
