Improvements in Third Party Owned Buildings

Facility name: Ogden Regional Medical Center

Project name: OGDNMC-012020M-New Rehab Unit
Location: OGDEN, UT
Project classification: Hospital – Shell Buildout
Project type: MOB
Project number: 3441500009
Lesson Learned number: 182
Impact: Cost, Schedule, Quality, Scope

Cost impact: $65,000 Schedule impact: 10 days


Lesson Learned/Best Practice

For HCA Tenant Improvement Projects located in 3rd Party Owned Buildings, verify existing construction is suitable to allow work to start and avoid schedule delays.


Suggested Actions for Future Projects

HCA Design and Construction, the Design Team, and the Contractors should walk the area as soon as access is available to review the existing construction conditions.

At any point during planning, design, or pre-construction that a non-compliant issue arises, it should be communicated to all parties so solutions can be determined prior to planned construction start.

Example

New 3rd Party Owned Medical Office Building utilizing Fiber Mesh Concrete Reinforcement in slabs which lead to severe cracking and fiber “residue” in existing slab. Cracking is a structural issue that needs review by a structural consultant. “Residue” of Fibers on the face of the slab affects flooring installations and required a planned solution.

Motorized Dampers at Louvers

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: 181
Impact: Cost

Cost impact: $49,705


Lesson Learned/Best Practice

CEP mechanical drawing required a quick opening motorized damper at the louvers on the north wall of the CEP and requires that the dampers are interlocked with the generator.  The louvers at this particular location in the CEP were specified to be architectural louvers by Construction Specialties as CS Model DC-9614 and were provided accordingly. The CS Model DC-914 louver does not require motorized dampers to achieve the specified wind driven rain performance.

There are other smaller mechanical louvers in the CEP and louvers with motorized dampers in the CEP that were provided by the mechanical contractor and were specified as Pottorff Model ECD-545-MD in the mechanical specifications, which require a motorized CD-51 damper option to achieve wind driven rain performance.  These louvers that include the motorized dampers were interlocked with their respective equipment as specified. 

Based on the specification noting the use of motorized dampers at the Pottorf  louvers for wind driven rain performance, the mechanical contractor assumed the CS Model DC-9614 would also come equipped with the motorized dampers and therefore did not carry the motorized dampers required to interlock with the generators per sheet M1.02. Cladding Systems who provided all CS Model DC-9614 louvers did not carry any motorized dampers as the louvers did not require it.


Suggested Actions for Future Projects

Our lesson learned is to ensure that anytime louver scope is being divided between mechanical and architectural specifications, ensure all components of the louver system are properly reviewed for coverage and gaps do not exist. We specifically studied and coordinated quantity, location, finish, blank-off panels at louvers with no mechanical connections / purpose and louvers with ducted O/A connections to ensure there were no scope gaps and were successful on these items, however, the project team did not vet the motorized dampers which were specified only at a couple locations on the entire project.

OR Ceiling Height

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: 180
Impact: Cost, Scope


Lesson Learned/Best Practice

Renovations involving OR hard lid ceiling prevent the ability to review above ceiling conflicts in advance.


Suggested Actions for Future Projects

Account for more contingency room due to unknown ceiling conditions. Where existing structures are cast in place, above ceiling existing structure should be evaluated before establishing finished ceiling heights.

Minor Renovations

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: 179
Impact: Cost, Schedule, Scope


Lesson Learned/Best Practice

“Minor Renovation” OR rooms become full demo rooms if more than cosmetic upgrades are performed.


Suggested Actions for Future Projects

Determine during design if Minor Renovation OR rooms are truly appropriate/desired, because if anything other than cosmetic upgrades are required, the cost impact will meet or exceed a full renovation.  Replacing/relocating existing HVAC equipment, adding new lights, and installing a stainless steel package requires a tremendous amount of demolition.

Long Lead Items on Accelerated Schedule

Facility name: Ogden Regional Medical Center

Project name: OGDNMC-012020M-New Rehab Unit
Location: OGDEN, UT
Project classification: Hospital – Shell Buildout
Project type: MOB
Project number: 3441500009
Lesson Learned number: 178
Impact: Schedule

Schedule impact: 25 days


Lesson Learned/Best Practice

For Projects with Accelerated Schedules and no time for Early Release of Long Lead Time Materials, verify materials can be obtained in time to meet the required schedule during Preconstruction.


Suggested Actions for Future Projects

Plan for Early Release of Long Lead Time Materials, Equipment (Contractor and Owner Provided including Equipment , IT&S and Unified Communications), review the need for these items early in the project development to review options for obtaining items in time to meet the required accelerated schedule.  Ensure to review these potential early items with DM and CM during RFP and design phases.
