The first step was to better view and assess the cracking by removing the exterior coating.  To accomplish this, scaffolding was erected and then enclosed with white shrink wrap. Negative air monitoring was implemented 24/7 inside the wrap, as well as exterior air monitoring, to confirm that no contaminants from the work became airborne. 

Then, the one-half-inch plaster layer that covers the building’s structural concrete shell was saw-cut to access and seal the concrete structural shell cracking.  Caulking was replaced at exterior openings, and cold joints and flashing were added at various locations.

In total, the project repaired approximately 2,750 linear feet of horizontal cold joints and approximately 3,600 linear feet of exterior concrete shell cracking. 

On track for on-time completion, the final step of exterior painting has begun.
