Lesson Learned/Best Practice

It was identified during the installation of the Neopod Staff Toilet Rooms, that access to the shut off valves was missing. The shutoff valves are located on top of the Toilet Room and are inaccessible through the gyp board that goes to deck. All of the Neopod Patient Toilet Rooms have shut off valves located in the corridor and have adequate access.


Suggested Actions for Future Projects

Coordinate required access for shutoff valves, etc to be outside of any prefabricated unit foorprint and add access panels as required..

Exterior Skin Finish

Facility name: Menorah Medical Center

Project name: MENORA-092018M-Bed Tower Expansion
Location: OVERLAND PARK, KS
Project classification: Hospital – Horizontal Expansion
Project type: Acute Care
Project number: 0972300007
Lesson Learned number: 137
Impact: Cost, Quality


Lesson Learned/Best Practice

During EDI two different finish types were selected.  Precast concrete was selected for the lower level and EIFS was selected for the upper levels in order to reduce cost.  Both finish colors were selected to closely match the existing building however, with the two different skin types, the different finishes stand out.  There is a texture difference between the two skins as the precast has a rough finish and the EIFS is smooth finish.  Now that both skin elements have been installed it is apparent how different they are raising concern from the facility on the appearance.


Suggested Actions for Future Projects

We recommend that in future tie-in expansions, where the goal is to match existing finishes, that only one skin element is used.  This will help to give the match a consistent look.

Project number: 2689500001
Lesson Learned number: 135
Impact: Cost


Lesson Learned/Best Practice

BLOX Patient Bathroom lights are fed from critical branch power, per HCA & ICT guidelines, and are fabricated with flex conduit connections. The City of Orlando requires that all critical branch power be ran in rigid conduit


Suggested Actions for Future Projects

If a BLOX design alteration for the City of Orlando is not feasible, the contractor should carry cost to remove flex conduit and install rigid pipe in the City of Orlando.

Transformer and Switchgear Coordination with Utility Company

Facility name: Menorah Medical Center

Project name: MENORA-092018M-Bed Tower Expansion
Location: OVERLAND PARK, KS
Project classification: Hospital – Horizontal Expansion
Project type: Acute Care
Project number: 0972300007
Lesson Learned number: 115
Impact: Cost, Schedule, Quality


Lesson Learned/Best Practice

Early understanding of local code requirements for the transformer and switchgear pads is important as this could impact the release of prefabricated duct banks.  If the equipment pad sizes and locations are not correctly identified this could cause rework of prefabricated material.


Suggested Actions for Future Projects

Coordinate early with the local utility company and design team in order to correctly identify the transformer and switchgear pad requirements and location.

Early install of Interior Prefab Components

Facility name: East Florida Division Office

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.

Afternoon Prefab Deliveries

Facility name: East Florida Division Office

Project name: DAVHOS-102018M-New Hospital (NOVAMC)
Location: Davie, FL
Project classification: Hospital – New
Project type: Acute Care
Project number: 3597900001
Lesson Learned number: 107
Impact: Schedule, Safety


Lesson Learned/Best Practice

Even though the hospital project had 3 tower cranes, dedicating a crane full time for a day for BLOX deliveries was not optimal. The team elected to start the first BLOX delivery after 3:30pm, when normal production work for the day was wrapping up. This would allow for uninterrupted use of a tower crane and ensured less overall traffic on the floor. This helped to lower congestion on the jobsite during the day and created a calm environment to move multiple 3500lb prefabricated units onto the floors of the hospital. The team saw the multiple benefits of delivering the BLOX units after hours and continued this practice for the rest of the job with great success.


Suggested Actions for Future Projects

Consider bringing in prefab components after normal working hours, to insure most efficient install and minimal congestion. This is especially true when there is heavy use of the project cranes throughout the days.

Exterior Finishes Selection

Facility name: Menorah Medical Center

Project name: MENORA-092018M-Bed Tower Expansion
Location: OVERLAND PARK, KS
Project classification: Hospital – Horizontal Expansion
Project type: Acute Care
Project number: 0972300007
Lesson Learned number: 103
Impact: Cost, Schedule


Lesson Learned/Best Practice

During the EDI process there was a lot of emphasis put into the main skin finish selection, for precast and EIFS, while the metal panels, louvers, curtainwall, and misc. finishes were not selected.  The intent was for the exterior finishes to match the existing building but was not noted as such in the Construction Documents.  This caused the GC and architect to spend a lot of time reviewing samples in order to find the appropriate color for the exterior finishes.  The result of this process was added cost, and lead time for material procurement, due to selecting a custom color.


Suggested Actions for Future Projects

When new construction is tying into an existing building exterior finishes should be selected during design.  For an accurate color match, and to appropriately account for associated cost, the CDs should indicate the manufacturer and color to match.


Actions Taken / Current Status

HCA comment:  The preferred method is the design team details matching or coordinated colors with existing building exterior finishes for the new finish details when possible.

Submittal process for prefabricated headwall units

Facility name: P-SL Medical Center

Project name: PRSTLK-022017M-Pre-Op & Recovery
Location: DENVER, CO
Project classification: Hospital – Renovation
Project type: Acute Care
Project number: 2720000019
Lesson Learned number: 89
Impact: Schedule


Lesson Learned/Best Practice

Start the submittal process for prefabricated headwall units at the start of the project.  Headwall units were not submitted and approved by the time they were ready to be installed resulting in out of sequence work for the patient bays. Because the headwall units are required when walls are being framed they need to be submitted and approved as soon as possible because they have a significant lead time.


Suggested Actions for Future Projects

For trade fabricated headwalls, trade subcontractor must coordinate with the design team upon award to ensure that shop drawings are developed, submitted and approved in a timely fashion to avoid schedule delays.
