The Dunn Tower Refresh includes full architectural upgrades and a refresh to patient rooms, patient restrooms, nursing stations, work areas, public elevator lobbies, and waiting rooms. As the project was in progress - half of the floor was still in operation. There was an extensive need for coordination and planning with hospital stakeholders to replace the majority of the existing domestic water, sanitary sewer, and sanitary vent lines. Any shutdowns that took place during the refresh were identified, planned, coordinated, and executed above active operating rooms and labor and delivery rooms, which included a full building domestic water drain down, all completed successfully.
A unique project feature was the prefabricated headwall system, by implementing this system on the project, several added benefits shinned through. During the early stages of procurement of the headwall frame system, DPR was able to begin MEP and rough-in modifications early on in the project schedule versus a typical built-in place system. Additionally, the prefabricated headwall system allowed for consistency and superior quality control. There were fewer trade partners involved in the fabrication of the headwall system, eliminating the variable of having multiple trade partners with an array of skills to install a built-in place system in a complex environment. Taking a step further, DPR shifted the fabrication to an off-site facility which reduced the onsite workforce, reduced risk, injuries and safety incidents, and eliminated the logistical challenges of mobilizing a large labor force in a congested urban environment.
DPR's SPW team self-performed the demolition, framing and drywall, doors, frames, and hardware, modular headwall installation,acoustical ceilings, and infection control risk assessment (ICRA). Our SPW efforts allowed for DPR to control and advance the schedule - specifically during the demolition phase, DPR was able to call upon 60 craft workers to selectively demolish 56,000-sq.-ft. between four floors in one month, one week/floor.
