Rooftop Piping Across Existing Structures

Facility name: Orange Park Medical Center

Project name: ORPKMC-102018M-Kitchen Expansion & Renovation
Location: ORANGE PARK, FL
Project classification: Hospital – Renovation
Project type: Acute Care
Project number: 3091300034
Lesson Learned number: 162
Impact: Scope


Lesson Learned/Best Practice

Pipe routing seems to often be left to the installing contractor.  When rooftop piping is used, the support frames are done by the installer as a deferred submittal, but the underlying structure has to be reviewed by the design team. Field investigation should be performed to identify/incorporate existing structure components/limitations into the design documents. 


Suggested Actions for Future Projects

Large diameter piping being routed over existing roof sections needs to have those existing roof sections surveyed prior to the completion of design. The survey should identify the structural make-up of each roof section, so appropriate routing and pipe stands can be coordinated/designed into the construction documents with the structural engineer’s approval.

Facility Protection Protocol

Facility name: Ocala Regional Medical Center

Project name: OCALMC-092018M-Vertical Bed Expansion
Location: OCALA, FL
Project classification: Hospital – Vertical Expansion
Project type: Acute Care
Project number: 3092700031
Lesson Learned number: 160
Impact: Safety, Scope


Lesson Learned/Best Practice

Vertical Expansions are high risk regarding patient environment of care and to the physical care of the facility itself. Inspections and checklists should be reviewed constantly as the jobsite and structure are continuously changing at a rapid pace. One of the biggest, if not the most risk on any Vertical Expansion projects is water intrusions. From the moment you set the first column, you have the potential to expose the facility to water. 


Suggested Actions for Future Projects

We have developed numerous forms and checklists that cover all trade accountability and ensure that we leave the site knowing we are protecting patients and faculty. 

Along with the facility checklists and permits, we developed the Facility Protective Measures (FPMs) and Temporary Roofing Measures (TRMs).

Facility Protective Measures  – (Pre Task) This form lists out work being completed below the Vertical. It lists out the subcontractor performing the work, specific work to be completed, if work will affect patient care, department head approval, facility manager approval and a pre-task checklist before work is to be performed. (Post-Task) This form follows the work completion described in the “pre-task”. General Contractor and Subcontractor managers in charge sign-off sheet to verify that there are no hazards to the facility. 

Temporary Roofing Measures -This form lists trades working on the rooftop, weather conditions on site for the day, expected weather conditions for the following day, Close of business signoff check list includes rooftop and existing operational floor. This form is monitored and signed off by an onsite manager for all subcontractor managers and the general contractor manager.

HVAC Equipment Guy Wire Install

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: 158
Impact: Cost, Schedule, Quality


Lesson Learned/Best Practice

Guy wires need to be installed to construction details.  Details site spacing, guy wire angles, and structural/deck mounting requirements.  Having early discussions regarding details with the MEP trades, steel detailer, and structural engineer may result in an install pattern that saves additional steel bracing and provides clearer direction for specific unit installation.


Suggested Actions for Future Projects

Include in shop drawing review for placement and install of guy wire anchors.

Project classification: Hospital – Horizontal Expansion
Project type: Psych
Project number: 3833300011
Lesson Learned number: 148
Impact: Cost


Lesson Learned/Best Practice

With HCA’s ever evolving design standardization there needs to be a fixed point where design is frozen for each specific project. 


Suggested Actions for Future Projects

Document date and version of HCA standards utilized within CD drawing set,  validate HCA standards with planning manger, design manager, HCA engineering and construction manager.

Steel erection and soil conditions

Facility name: Aventura Hospital & Medical Center

Project name: AVENTU-New Tower
Location: AVENTURA, FL
Project classification: Hospital – Vertical Expansion
Project type: Acute Care
Project number: 3092000015
Lesson Learned number: 63
Impact: Schedule, Scope


Lesson Learned/Best Practice

Building in south Florida due to the soil type, the structural columns are set below grade two foot or greater. Due to the weather (mostly rain) we constantly fought to keep the sand from washing down around the columns after they have been cleaned out.


Suggested Actions for Future Projects

Review steel erection plan then get phasing plan set for all columns prior to steel erection beginning. Once work commences set columns, plum column, tighten all bolts, weld washer (as required). Then form up three of four sides, grout all base plates and then finish forming the fourth side. Let steel erection complete so if any pulling is required to connect beams there is play but the columns are formed up so no dirt can wash around prior to concrete pedestals poured.

Set up a coordination meeting with structural steel and concrete subs to layout a phasing plan to dig around, grout base plate, and form up the columns as to avoid have the earth wash back down around the column prior to pouring the column wraps below grade.

Coordination of steel and shell packages complete at DD

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: 49
Impact: Schedule, Quality


Lesson Learned/Best Practice

During the EDI process it was decided by the integrated team to start BIM processes after the completion of the steel shop drawings.  This decision was based primarily on avoiding rework of possible changes due to misc steel and bracing and any changes that may occur during design up until the ERP steel package.  This allowed for two additional months compared to pulling from hanger setting and prefab which would have resulted in the coordinating starting later.  The net effect however was that the BIM coordination took longer than expected and the project resulted in having BIM signed off model just in time for prefab and embed coordination.

Two main root causes involve the contractual requirements for multiple bids on steel asbuilts necessary for the steel shops and the steel shop review process coming still late in the process compared to ideal.  The ideal time for steel shops to be complete is closer to DD.  This would allow BIM coordination (re: MEP and electrical) to occur prior to CD’s being complete.


Suggested Actions for Future Projects

Emphasize the locking of the steel and shell packages by DD.

Tasks related to steel installation

Facility name: Orange Park Medical Center

Project name: ORPKMC-092018M-Bed Tower
Location: ORANGE PARK, FL
Project classification: Hospital – Vertical Expansion
Project type: Acute Care
Project number: 3091300035
Lesson Learned number: 48
Impact: Schedule


Lesson Learned/Best Practice

Current steel installation schedule activities often combine tasks for install and subsequently have multiple crews listed under on activity.  An example of this would be Steel Detailing which consists of multiple tasks such as decking, moment welds, bent plate, and welding studs.  It is imperative, especially on jobs with LPS, to have crew specific tasks and duration.


Suggested Actions for Future Projects

During pre-construction meeting, review the process the installer is planning and divide activities by major task and labor load accordingly.

Water Intrusion Prevention

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: 42
Impact: Cost, Scope


Lesson Learned/Best Practice

Water intrusion prevention plan (WIPP) should include more permanent “dog house” enclosures from field verification (survey) through dry-in to ensure minimally runoff prevention from primary rain systems.  Teams should work with roofing contractor and steel fabricator to develop a system that is further developed than cut and patch systems.  This would also apply to stub columns.


Suggested Actions for Future Projects

At time of steel survey have a “dog house” construction plan to be installed.


Actions Taken / Current Status

Sent to HCA Construction Management team for consideration and follow-up action.

Cluster or break-out groups in Early Design Involvement (EDI) projects

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: 29
Impact: Quality, Scope

 


Lesson Learned/Best Practice

Incorporate trade break out and/or cluster groups earlier in design; cluster (break-out) groups should be scheduled in coordination with Big Room meetings and started at beginning of project; We suggest the breakout meeting start the Big Room days so that items that are brought up in the breakouts that need to be discussed with the larger group there is still time to it.  Also, this would insure that the breakouts happen.

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.
