Vibrocompaction Footing Size Change

Facility name: Lawnwood Regional Medical Center

Project name: LAWNWD-062019M-New Tower and CEP
Location: Fort Pierce, FL
Project classification: Hospital – Vertical Expansion
Project type: Acute Care
Project number: 3093200010
Lesson Learned number: 185
Impact: Schedule, Scope

Lesson Learned/Best Practice

In EDI, we found that the original specified vibro-compaction and smaller footings directly adjacent to the hospital would cause too many issues with the existing facility, so we wrote an RFI to change the footings to larger ones and eliminate the vibrocompaction at those footings. This is to avoid the effects of the vibration to the hospital. Footings are oversize to remove need for vibro underneath.

Suggested Actions for Future Projects

When planning to use vibro-compaction, consider proximity of existing facilities.

Project name: MCMKNY-102017M-BH & Rehab Relocation
Location: MCKINNEY, TX
Project classification: Hospital – Horizontal Expansion
Project type: Psych
Project number: 3833300011
Lesson Learned number: 145
Impact: Schedule, Quality, Safety

Lesson Learned/Best Practice

Utilization of extensive utility exploration limited any interruptions due to interferences with existing underground utilities, utilized extensive hydro-vac excavation, survey was coordinated into BIM, early mobilization in anticipation of city permit.  Was able to accomplish a lot of the actions because was an EDI project. 

Suggested Actions for Future Projects

As possible integrate as many of the same methods for future projects.  Key is early mobilization to be able to take advantage of any mobilization or relocation due to unforeseen utilities identified.

Project classification: Hospital – New
Project type: Acute Care
Project number: 2689500001
Lesson Learned number: 117

Lesson Learned/Best Practice

The City of Orlando must review all utility as-builts prior to removing the Document Hold for a final Certificate of Occupancy. This process can be up to 30 days for each submissions with multiple submissions necessary.

Suggested Actions for Future Projects

Progress as-built surveys should be submitted when possible to reduce the schedule impact for revised documents at the end of the project.

Facility name: Parkridge Valley Hospital

Project name: PRKRVH-092018M-ED Addition
Location: CHATTANOOGA, TN
Project classification: Hospital – Horizontal Expansion
Project type: Acute Care
Project number: 3424100002
Lesson Learned number: 46
Impact: Schedule

Lesson Learned/Best Practice

City required excavation of the bio-retention pond and partial storm sewer system installation before to excavating the building pad.  This was not contemplated in the schedules and delayed development of the building pad by three weeks.

Suggested Actions for Future Projects

Have civil engineer discuss excavation and site utility installations prior to completion of construction documents and include any required sequencing or special provisions in the documents.  At a minimum the contractor should meet with the AHJ to ensure a thorough understanding of their requirements.
