7.0 PROJECT DELIVERY METHODS

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 Village in a comprehensive document and the
individual components are reviewed by Village staff and the design team
consultants. Comments are made to the CMAR and the price is adjusted
until a final agreement is reached.
Once the GMP is accepted, the second step in the two-step procurement
process commences—the construction phase. The CMAR performs all the
duties a general contractor would under a traditional DBB procurement.
Additionally, the CMAR also performs the following services:
Village would normally handle. In DB, these become internal team disputes
that may not involve the Village. Using the DB method, a preliminary
scope of work and budgetary opinion of cost would be prepared by an
independent consultant and the Village would then seek DB firms who
would be responsible for the design and construction of the entire project.
The following is a summary of the advantages and disadvantages of the
DB project delivery method:
Advantages:
 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)
 Conducts and arranges all meetings for the project, including
agenda development and minutes distribution  The Village will have one contract with a single entity for both
design and construction that simplifies contract administration
 Schedules and coordinates the work amongst the various trades,
owner, design team, and stakeholders  Similar to CMAR, cost efficiencies can be realized because the
contractor and designer work together throughout the entire project
 Tracks and provides a log of Contingency Use Directives (CUD)   Provides executive monthly reports regarding the project progress Change orders typically only occur due to changes to the original
scope that are initiated by the Village
 Participates in public outreach activities, including the role of
“Project Liaison” if desired by the owner.  Portions of the construction can be “fast-tracked” prior to fully
completing the design
To take advantage of the preconstruction services provided by the CMAR,
it would be important to contract with a CMAR during the design phase so
they have the opportunity to weigh in on the designs as they are released
and inform the compiled utility plans to achieve the most efficient design
and construction approach ahead of GMP development. Because this
would be a qualifications based selection, design plans and specifications
would not be needed until GMP development.
7.2.3
Disadvantages:
 For this project much of the schedule efficiency that DB can offer
is hampered significantly by the design efforts and schedules of
the utility owners. 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.
 For this type of project, 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 owners who are unwilling to grant an
easement. If liquidated damages are included in the contract, a
cost premium may be assessed by the design-builder to assume
the schedule risk. Additionally, the design-builder may be less
Design-Build (DB)
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. This delivery method is a service provided by a
single entity that provides both the design and construction services. The
main benefit is 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 the
