BLOX Units – Electrical Issues

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: 59
Impact: Cost, Schedule, Quality


Lesson Learned/Best Practice

Make sure BLOX tightens all EMT conduit screws and couplers. Failed electrical inspections because conduit screws and couplers were loose on many units. BLOX is having to bring in multiple electricians to repair onsite.  Need to do a root cause analysis with BLOX and HCA on why their QA/QC process missed this.


Suggested Actions for Future Projects

Improve offsite QA/QC.  Bring in local inspectors early once BLOX units are onsite.


Actions Taken / Current Status

Issue has been addressed by HCA Healthcare with BLOX.  Actions have been taken by BLOX to correct the problem.

Herman Miller Casework and flooring considerations

Facility name: Methodist Hospital

Project name: METHOS-102013P4-ED Renovation
Location: San Antonio, TX
Project classification: Hospital – Renovation
Project type: Acute Care
Project number: 3938500016
Lesson Learned number: 45
Impact: Quality


Lesson Learned/Best Practice

Herman Miller has planned to install casework after flooring is installed. This creates a challenge for floors with sheet goods because of the integral cove base. Layton has coordinated with Herman Miller to ship the toe kicks out early to install before flooring. Herman Miller is charging $250 to set the bases separately, but this will reduce the amount of seams in the sheet good flooring.


Suggested Actions for Future Projects

Install casework bases before flooring at sheet goods. Install rest of casework after flooring (as late as possible) to reduce the amount of time that damage may occur during construction.

Discuss with Herman Miller to include an additional install for casework bases at locations with sheet goods.

 


Actions Taken / Current Status

Sent to HCA Construction Management and Medical Equipment teams for follow-up action.

BLOX components delivery and installation scope

Facility name: Lake Nona Hospital

Project name: Lake Nona-102018M- New Hospital
Location: TALLAHASSEE, FL
Project classification: Hospital – New
Project type: Acute Care
Project number: 2689500001
Lesson Learned number: 39
Impact: Cost, Schedule, Scope


Lesson Learned/Best Practice

A scope gap was identified where labor was not bought out to collect, palletize and load BLOX headwall racks, panelized bathroom racks, rigging gear and mover jacks onto long haul shipping trailers contracted directly with BLOX. 

Ensure BLOX install foreman/subcontractor leadership responsible for loading BLOX hardware/equipment discussed project strategy at BLOX kickoff meeting on site to avoid confusion when BLOX install is complete in an area, phase, floor or project and hardware needs to be returned to BLOX facility in AL.

Ensure the specific phasing of BLOX delivery AND installation (if those two activities do not run finish-to-start) is reviewed in detail during the BLOX pre-mobilization meeting held on site.


Suggested Actions for Future Projects

Update BLOX install playbook to identify this scope responsibility and assign it to the GC to buyout with BLOX component installation.

On future projects, the BLOX install playbook should clearly identify that scope responsibility and the GC should ensure that labor responsibility is included with the installation of the BLOX components.

Installation of prefab bathroom pods

Facility name: Northeast Methodist Hospital

Project name: NRETME-092018M-Inpatient Expansion
Location: LIVE OAK, TX
Project classification: Hospital – Vertical Expansion
Project type: Acute Care
Project number: 3438500010
Lesson Learned number: 24
Impact: Quality


Lesson Learned/Best Practice

During the rigging of the bathroom pods. JED noticed that the spreader bar made it difficult for riggers to adjust landing in roof access. Depending on how the pod would be picked the spreader bar made the overall width larger than the pod itself.  An adjustable spreader bar would have helped for a smoother transition down the roof access hole on to level 5.

 


Suggested Actions for Future Projects

The solution is to have an adjustable spreader bar and straps to help with rigging of prefab bathroom pods.

Coordination of steel structures and exterior wall panels

Facility name: North Florida Regional Medical Center

Project name: NRFLMC-032018M-South Tower Vertical Expansion
Location: GAINESVILLE, FL
Project classification: Hospital – Vertical Expansion
Project type: Acute Care
Project number: 3091600012
Lesson Learned number: 23
Impact: Cost, Schedule, Quality


Lesson Learned/Best Practice

Steel structures must account for exterior wall panels.  The current method of early release package does not allow for a final steel design due to the lag of wall design.

Additional focus on early release package of panels along with steel.  Third party engineering of panels come subsequent to typically buyout of structural steel.


Suggested Actions for Future Projects

Coordinate the ERP package for both steel and exterior panels as early as possible for them to be concurrent.

Design of electrical conduit over skids

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: 17
Impact: Cost, Schedule, Quality


Lesson Learned/Best Practice

Don’t put large electrical conduits over CEP skids. Once we installed the CEP skid base, we had to stop for a month before installing the rest of the CEP skid risers and headers, while the overhead electrical completed.

Make sure in design or BIM coordination, that no large overhead work is above CEP skids.


Suggested Actions for Future Projects

Make sure a full height CEP skid can be installed and not in conflict with anything overhead.


Actions Taken / Current Status

Defer to CEP skid initiative for resolution.
