Avoiding a disaster.
As erection began, the construction team experienced a rare incident, a fire. The fire occurred when contracted welders were working above construction debris in the basement of the structure, while welding metal, the sparks set the foundation waterproofing on fire. Fortunately, the fire was contained quickly and isolated to a small area contained on three sides by precast.
The fire-resistant nature of precast concrete as a non-combustible material effectively stopped the fire from spreading; while the other adjacent materials burned, the concrete did not. If the fire started on a traditional stick frame building a catastrophic event could have occurred, halting, or even completely stopping construction and development. Because it was a precast concrete building, the structure only suffered smoke damage and construction resumed the following day.
Moving construction and erection forward was paramount. Finding equipment to continue building the residential condo in a packed urban environment required high-level thinking. Because the structure had zero lot line to the adjacent site, Wells had extremely limited space to manage concrete erection. Our erection team utilized a unique tool, a luffing tower crane to accommodate large holding capacity in narrow movements on the constrained site, placing heavy precast members throughout the structure.
The new development on 6th and Santa Fe is a beautiful yet resilient total precast structure, that will continue to provide a safe place to live in downtown Denver, CO, for years to come.
