Project name: DAVHOS-102018M-New Hospital (NOVAMC)
Location: Davie, FL
Project classification: Hospital – New
Project type: Acute Care
Project number: 3597900001
Lesson Learned number: 113
Impact: Schedule, Quality

Lesson Learned/Best Practice

At HCA Davie, the hospital project was a 4 level concrete frame, and the team could not start the exterior walls, interior framing, or overhead MEP until the reshores were removed and the top concrete deck was poured. B&G decided to bring in BLOX components as soon as reshores were removed and layout was complete, creating a unique advantage in sequencing and an early release of subsequent trades inside the hospital. Typically, BLOX components are not installed until the building is mostly dry and the envelope is closed in, so the main risk in bringing in the units this early was keeping the units protected from the elements with no skin on the building. Utilizing additional boat wrap and leaving the bottom 1’ off of the headwalls helped keep the units dry while allowing the early delivery to streamline the prefabricated interior components’ delivery and installation.

Suggested Actions for Future Projects

–          This approach proved to be successful for the team, and is being utilized on Lawnwood as well.

–          It does require some focused attention and extra work to keep the units dry.

–          Two steps the team took were: 1) Re-boat wrapped some of the bathrooms to keep them dry until we set them when the exterior was complete. 2) Leaving the 1’ of drywall off the bottom of the headwalls (see other lessons learned for this)

Actions Taken / Current Status

HCA comment:  The General Contractor is advised to check with the local AHJ to insure they will accept this practice.
