The GMP for the project will consist of the following
elements:
y y Complete quantity survey for the project.
y y Public advertisement for the subcontractor bids.
y y Prequalification of the subcontractors.
y y Analysis of all subcontractor bids to eliminate gaps and
incomplete bids.
y y A detailed construction schedule.
y y Itemized breakdown of all direct costs, general conditions,
CMAR management fees, overhead and profit, and the
Owner’s contingency.
The GMP is presented to the Town in a bound document
and the individual components are reviewed by Town staff
and the Design Team consultants. Comments are made to
the CMAR and the price is adjusted until a final agreement is
reached.
Should the GMP be accepted, the second step in the two-step
procurement process commences. This is the construction
phase. The CMAR Performs all the duties that a general
contractor would under a traditional DBB procurement.
Additionally, the CMAR also performs the following services:
y y Conducts and arranges all meetings for the project
including agenda development and minutes distribution.
y y Schedules and coordinates the work.

y y Tracks and provides a log of Contingency Use Directives
(CUD).
y y Provides executive monthly reports regarding the project
progress.
y y Participates in public outreach activities, including the role
of “Project Liaison” which has been proven to be especially
beneficial to the Town on past projects. The following is a summary of the advantages and
disadvantages of the DB project delivery method:
7.2.3 Design-Build (DB) y y The Town will have one contract with one entity for
both design and construction which simplifies contract
administration.
The Design-Build (DB) delivery method has gained
popularity and is sometimes seen by the industry as a solution
to the limitations of the other project delivery methods. The
DB delivery method is a service provided by a single entity
that provides both the design and construction services. The
main benefit is that the DB provides a single responsible party
for the design and construction of conventional projects.
DB combines engineering and construction services under
one contract minimizing the disputes that the Town would
normally handle. In DB, these become internal team disputes
that may not involve the Town. Using the DB method, a
preliminary scope of work and budgetary opinion of cost
would be prepared by an independent consultant and the
Town would then seek DB firms who would be responsible
for the design and construction of the entire project.
Advantages:
y y DB can theoretically deliver a project in a shorter amount
of time than a conventional DBB because there is only one
selection process (DB team) instead of two (design team
and contractor).
y y Similar to CMAR, cost efficiencies can be realized because
the contractor and designer work together throughout the
entire project.
y y Change orders typically only occur due to changes to the
original scope that are initiated by the Town.
y y Portions of the construction can be “fast-tracked” prior to
fully completing the design.
Disadvantages:
y y The Town has significantly less control and involvement
over a DB project than traditional DBB or CMAR.
y y Much of the schedule efficiency that DB can offer is
hampered significantly by the design efforts and schedules
of the utility owners on this project. This is because the
Design-Builder exercises little control over these entities so
they pose a significant schedule risk to the Design-Builder
in both the design and construction phases of the project.
The enhanced level of risk may cause the Design-Builder
to charge a risk premium to cover the potential of assessed
liquidated damages. Additionally, seasonal construction
restrictions to minimize traffic impacts will also prevent
maximum schedule efficiency from being achieved.
y y To take full advantage of any shorter implementation
benefits that DB offers, the Town must be highly responsive
in its decision making.
y y The Town loses the benefit of the checks and balances that
exist when contracting separately with independent design
consultants and a general contractor or CMAR.
y y May be problematic when there is a requirement for
multiple agency design approvals such as Landmarks and
ARCOM.
y y The easement acquisition process would be problematic
under the DB delivery method. If the Design-Builder is
responsible for obtaining easements, there is a schedule and
cost risk due to property o
