VILLAGE OF KEY BISCAYNE UNDERGROUNDING OF UTILITIES — MASTER PLAN
Because of the requirement for FPL to harden their infrastructure,
design and construction of this undergrounding program should
begin as soon as practical
Pre-Construction Services/Bidding/Award of Phase 1 is to
begin in the first quarter of the year to allow adequate time for
pre-construction activities and GMP development needed to
prepare for an early June construction start. This allows “heavy”
construction activities to happen around the school during the
summer months.
Community outreach is a continuous process that spans across
design and construction
Construction Phase Schedule
Considerations
110
In general, construction activities around the K-8 school should be
coordinated to occur during the summer in any one phase
“Heavy” construction activities, such as underground infrastructure
work and conduit installation, are desired to be constructed in the
summer months when traffic volumes are lowest
Year-round construction activities are considered for the
undergrounding program
Water main, stormwater, and conduit installation activities may
occur simultaneously in any phase area.
To minimize community/traffic impacts, “heavy” construction
impacts will not be allowed to occur in adjacent phases at the
same time
Cable and equipment installation activities may overlap the duration
of backbone conduit installation within a phase
To achieve schedule compression, portions of phases that can
be overlapped should be to the greatest extent practical while
minimizing traffic and resident impacts
Feeder switch over to the underground system should be
coordinated to occur in the cooler months when electrical
demand is low, which reduces the complexity of the process and
associated costs
Conversion of individual electric and communications services will
follow the energization of the new underground system
Overhead wire and pole removal cannot begin until all services are
converted to the new underground system
Roadway, sidewalk, and landscape improvements may occur
during the final restoration stage of each phase
Schedule Durations
The durations of significant activities that occur within each project phase
were developed based on information gathered from a variety of sources.
Design durations are largely based on Kimley-Horn’s experience with
similar projects and through schedule discussions with FPL, AT&T, and
Comcast.
Construction activity durations were based on relevant projects currently
underway or already completed. These were compared to the activities
proposed in this master plan as part of the opinion of cost development,
which yielded significant activity durations and were then incorporated into
the overall schedule. Appropriate schedule contingencies were also applied
to account for normal weather impacts, potential geological challenges,
and unforeseen conditions.
