Project Details
BJC Queeny Tower
Kadean provided preconstruction services support early on for this project in support of the hospital system and the design team. We conducted investigations, reviews, and budgeting for multiple drawing packages. The project had three major components: Electric Relocation, MEP/FP Disentanglement, and Demolition, each with unique challenges.
In the Electric Relocation phase, we coordinated with Ameren to construct a new utility substation and install three 35KV primary switchgears for the South Campus. We rerouted power to eleven interconnected buildings using 4160V secondary systems, which involved installing new conduits and conductors above ceilings. To ensure safety, temporary containment areas were created to isolate patients, the public, and employees during construction. Switching over to the new service was done at night to minimize disruption to patient care and hospital operations. The MEP/FP Disentanglement phase involved rerouting or re-establishing various systems, including MRI cooling, HVAC, med-gas, fire sprinklers, and steam piping. These systems served multiple buildings and required careful planning to minimize disruptions.

The demolition phase involved a twenty-two story concrete building, Queeny Tower, which presented challenges due to patient safety and hospital operations. Dust mitigation and falling object protection were prioritized, and measures such as additional pre-filters and real-time air sampling were implemented. The tower was enclosed on three sides using scaffolding with plywood or netting to contain dust and debris. Demolition was done floor-by-floor, with processed materials using elevator shafts and oversized materials handled by a 275-ton crane. Recycling efforts diverted 19,600 tons of concrete and 1,600 tons of metals from landfills.
