Finish Upgrades Scope of Work

Facility name: Woman’s Hospital Of Texas

Project name: WMHOTX-122018P1-5th Floor Ante-Partum Buildout & Renovation
Location: HOUSTON, TX
Project classification: Hospital – Renovation
Project type: Acute Care
Project number: 3431900010
Lesson Learned number: 167
Impact: Cost, Schedule, Scope


Lesson Learned/Best Practice

Scope not clearly defined on plans but required to perform specified activities; drywall touch up/finishing, removal of existing electrical devices to remain, plumbing fixtures needed to be removed prior to new flooring install, grab bars, mechanical grilles, sprinkler head relocations to accommodate new ceiling layout.

Finish plan shows new ceramic tile flooring and wall tile at existing patient room bathrooms. However, demo plan did not provide specific notes to remove all existing fixtures and division 10 items and reinstall for new finishes.


Suggested Actions for Future Projects

At a minimum, provide more detailed notes and callouts on construction documents, particularly on the demo drawings, where removal/reinstallation of existing items to remain should be picked up.  Best practice would be to walk each area and create a specific detailed plan showing all items and their locations for further detail and clarity.

Kitchen Exhaust Hoods

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: 165
Impact: Quality


Lesson Learned/Best Practice

Careful attention should be considered regarding the design of the exhaust hoods for kitchen equipment. Typically this scope of work is handled by an outside vendor that designs the system. We have experienced one of our hoods over the serving line Grill, that does not fully exhaust the heavy hamburger smoke, causing small amounts of smoke to roll out of the corners of the exhaust hood and out into the open serving area. Months of investigative efforts have resulted in adjustments/modifications to the system to correct this.


Suggested Actions for Future Projects

Any large smoke producing equipment should be kept against a perimeter wall that goes full height up to the exhaust hood. This approach is likely to reduce the possibility of a similar issue.

Central Energy Plant (CEP) Temporary Plant

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: 164
Impact: Cost, Scope

Cost impact: $64,000


Lesson Learned/Best Practice

Air-cooled chiller rental agencies have their own operational standards for their equipment which do not always match manufacturer operational standards. A temporary variable primary chilled water system was the basis of design for this project to match the existing chilled water plant configuration. The design team worked with the temporary unit manufacturer to ensure proper operation was being met. However, the rental agency would not allow for the operation of the chillers in a variable primary system. This resulted in added piping and pumps. In addition to this, the rental agency did not provide a control interface for the rental units. This caused for additional control wiring/sequencing for the temporary units.


Suggested Actions for Future Projects

When providing a temporary chilled water plant that utilizes rental air cooled chillers, provide a primary/secondary pumping configuration. Additionally, provide the temporary control system sequence as part of the design. Review the system configuration with the contractors and rental agency to ensure that their internal operational standards are being met and controls can be accomplished.

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.

Central Energy Plant (CEP) Replacement Coordination and Phasing

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: 161
Impact: Cost, Schedule, Scope

Cost impact: $15,000


Lesson Learned/Best Practice

During construction the team was able to coordinate the installation of the new utility lines in a way that minimized the overall duration of the temporary CEP services. During this process multiple phasing plans were developed to tackle the existing utility layouts that were uncovered. A complete mapping of the existing systems would have prevented the back and forth of multiple phasing plans and expedited the overall underground installation process. 


Suggested Actions for Future Projects

How to minimize the duration of a temporary CEP:
– A complete interior and exterior mapping and phasing plan should be developed prior to construction. This is advised in order to reduce potential impacts once construction begins.
– How much existing roadway/sidewalk will need to be removed/replaced to accomplish the phasing of both demo and replacement? 
– Schedule of when each existing and new item is to be removed/installed.

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.

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.

Vavle Location Maps and Tags

Facility name: P-SL Medical Center

Project name: PRSTLK-022017P1-Surgery Renovation
Location: DENVER, CO
Project classification: Hospital – Renovation
Project type: Acute Care
Project number: 2720000020
Lesson Learned number: 140
Impact: Cost, Schedule, Quality, Safety


Lesson Learned/Best Practice

It has been stressed by our HCA construction manager to inform all on site personnel of the location of shutoff valves in case of an emergency. Layton took it upon ourselves to create a map that is hung in different areas throughout the construction space that shows the location of all shutoff valves in our construction area. We have also implemented valve tags that hang down so the valves can be easily identified.


Suggested Actions for Future Projects

At the beginning of the project create a map that identifies shutoff valve locations and hang valve tags so that shutoff valves can be easily identified.
