Gagnon Cardiovascular Center Overbuild
As part of Atlantic Health System’s (AHS’s) ongoing mission to provide the most advanced heart care at Morristown Medical Center, The Gagnon Cardiovascular Institute is undergoing a two-story expansion that includes 72 private patient rooms, a five-elevator vertical expansion, and two stairwells.
During the preconstruction phase, Structure Tone New Jersey worked closely with AHS and their design partners to provide real-time budgeting and create a technical, logistical strategy to add two stories on top of occupied patient rooms. The technical components the team considered in their logistical approach included:
- Steel beam installation: The team will maintain a watertight envelop at the end of every workday.
- HVAC: Phased steel installation will allow existing AHUs to stay active until the new AHU is online.
- Three-bank patient elevator phased expansion: One elevator will remain active as the other two are being renovated. Once the two are turned over, the team will expand the last car.
- Two-bank passenger elevator expansion: The team will maintain a watertight envelop at the end of every workday.
- Two stairwells vertical expansion: The team will maintain a watertight envelop and stairwell egress while the roof is being removed.
- Curtainwall system: Anchoring details are different on each floor and require a detailed logistical approach. The existing parapets will be opened for steel plate supports, flashing, and bolting the curtainwall starter track. The team will maintain a watertight envelop at the end of each shift.
These logistical details had to be planned ahead of time for proper subcontractor purchasing and to maintain Atlantic Heath System’s budget.
