VILLAGE OF KEY BISCAYNE UNDERGROUNDING OF UTILITIES — MASTER PLAN

If the Village chooses to execute capital projects at the same
time as the undergrounding program, procurement under this
method could lead to some elements of the work being managed
by a contractor who is inexperienced in that given discipline. For
example, if drainage work needs to be completed only on one
street in the project phase area, the undergrounding scope of work
will far outweigh the drainage scope of work. This will potentially
lead to an electrical contractor being forced to manage a drainage
project. That would be highly unusual for the electrical contracting
community. This lack of experience could lead to detrimental
outcomes for both the drainage and undergrounding scopes
of work.
 This method can require additional Village staff for construction
oversight, coordination, and communications.
 For this project, technological and programmatic obsolescence
could become a problem since this is a very large, long lasting
project. This is mitigated somewhat by constructing the project in
phases. However, changing technologies and the deployment of
technology by FPL, AT&T, and/or Comcast during the construction
process will put the Village at a disadvantage when negotiating
these changes into the contract if, and/or when, they occur.
7.2.1.1 – DBB Contracting and Procurement Methods
There are several types of contracting methods to be used under the DBB
project delivery type. A very common approach is the lump sum, or fixed
price bid. This is commonly used in the vertical construction industry or
for any project where quantities are not easily measured. The Village is
accustomed to this method, as well as the unit-price method, which is
commonly employed in the horizontal construction industry. A complication
that can arise in the administration of construction for undergrounding
projects is the quantification of the extensive number of conduits of varying
sizes that will be installed under the project. For this reason, the electrical
undergrounding contracting industry is more accustomed to the fixed
price, or lump sum bid, approach to procuring this type of work. This
approach also shifts the responsibility for quantification to the contractor,
which reduces the Village’s risk of quantity overruns (or under runs and the
claim for lost profits) that may have occurred under a unit price approach
for the same work.
For this project, it would be important to procure the contractor once the
utilities have released their designs and after the compiled utility plans
have been prepared. Because this is a fixed price procurement method,
prospective contractors would need fully developed and permitted design
plans and specifications to bid from. The Village would be expected to
have easements acquired and designs finalized to avoid change orders
during construction.
