Key Biscayne Master Plan 043944000.18w_Key_Biscayne_MP(forJooMag) | Page 7

1.0 EXECUTIVE SUMMARY
The program is proposed to contain four phases. In an effort to accelerate
the implementation schedule each phase may contain separate sub-
phases or work areas. Each phase is anticipated to have a construction
duration of 18 to 24 months. A new phase will begin construction in each
year between 2020 and 2024. This allows for adjacent phases to overlap
in their duration, which in turn accelerates the implementation schedule.
In general, phase 1 through 3 work will begin at the south end of the
Village and progress north while phase 4 will return to the south to convert
Mashta Island and finish up the west side of the Village. This plan also
provides recommendations related to the timing of major infrastructure
projects performed by the Village and outside entities in an effort to
minimize community impacts and take advantage of potential cost saving
efficiencies.
Project Delivery Method
Recommendation
The Village’s undergrounding program is a very large and complex
infrastructure program that will be implemented in a phased manner over
the next four to six years. It may include not just the undergrounding scope
of work, but also roadway and stormwater improvements, water main
replacement, and landscaping upgrades. In developing recommendations
for project delivery methods for each of phases, the risks to schedule,
level of service expectations, and cost must be carefully considered. The
more improvements you include in the program the higher the risk. If
any single-phase falters in any of those three areas of risk, the remaining
phases of the program will be detrimentally affected. For this reason, the
project delivery method must balance those risks while yielding the highest
probability of project success.
Although the delivery method that ultimately gets chosen may depend
largely on how much work the Village would like to accomplish as part of
the program, this master plan recommends that the Construction Manager
at Risk (CMAR ) method of project delivery be used because, in our
opinion, it yields the highest probability of success for delivering the various
phases of the Village’s Undergrounding Program.
