7.0 PROJECT DELIVERY METHODS
reduced owner personnel required to manage the efforts of the CMAR is a
cost savings that needs to be considered. program schedule. This can lead to increased costs due to labor/material
price increases over time.
The CMAR process offers the Village “open book” transparency on how
the construction price is developed. All of the subcontractor bid proposals,
CMAR overhead, project management, profit, and contingencies are
clearly identified, shared with the Village, and agreed upon before the work
begins. This also allows the Village to know the full project budget, unlike
the DBB method where budget issues may not be discovered until well into
the construction process. CMAR has the ability to fast-track certain activities. Working with the
design team, elements of the project design can be completed early so
construction of those elements can commence in an expedited manner.
This can be advantageous for infrastructure elements such as water and
drainage improvements that may need to be constructed in advance of the
undergrounding infrastructure due to sequencing requirements.
As compared to other project delivery methods, the Village maintains a
greater degree of control over the construction budget and use of any
contingency funds. Change orders are inevitable in any underground
infrastructure project. While upfront sub-surface investigation mitigates
this risk, it cannot eliminate the risk. In a DBB project delivery, the owner
and design professional work together to manage the rising project cost
due to change orders on the project. In a CMAR project delivery, the
owner and design professional work together to preserve the construction
contingency, which ultimately lowers the final cost of the project.
A cost advantage may be achievable through the Village’s direct purchase
of materials, which can be streamlined through use of the CMAR
procurement method. The CMAR can coordinate these efforts directly,
retain responsibility for accepting delivery, storage and installation of these
materials while achieving tax savings for the Village.
Kimley-Horn’s history with this delivery method has been positive with
projects being completed on-time or ahead of schedule and under the
negotiated GMP. When the cost of the project is less than the GMP, the
contingency funds are returned to the Village.
Schedule
Schedule is very important to the Village due to pressure from FPL
to covert overhead lines or risk FPL moving forward with their storm
hardening efforts. Because this is a phased program, a substantial delay
in one phase can impact the ability to begin construction in a subsequent
phase. These delays can create a domino effect that can impact the overall
Additionally, schedule compression may allow flexibility when it comes
to installing certain project components at certain times of the year, thus
facilitating a successful project completion. For example, highly disruptive
roadway impacts are more desirable in the summer months when traffic
volumes are typically at their lowest.
As part of a lessons learned approach, there are also technical reasons for
performing certain construction tasks at certain times of the year. Feeder
transitions from the overhead to the underground system at the phase
boundaries are much more desirable in the winter time when electrical
demand is low. Performing these transitions during the hotter months
can drive up costs because the process becomes more complicated to
execute.
By obtaining constructability comments and perspectives from the CMAR
during the design process, the Village can achieve schedule efficiencies
that are not available under traditional DBB. Reducing the schedule
duration will reduce the cost of the general conditions on the project.
Level of Service
Although not identified by the UUTF as a high priority, a major criterion
in choosing a project delivery method for this program is the delivery
method’s ability to accommodate the needs of various stakeholders
in a complex environment. The Village works very hard to protect the
interests of the community. A high level of service and responsiveness to
community needs, desires, and concerns is considered very important.
The undergrounding program is fundamentally different than most Village
projects in that the work is not confined to Village property or the public
