7.0 PROJECT DELIVERY METHODS
7.2
Overview of Project Delivery Methods
The following provides descriptions and a summary of the advantages
and disadvantages of the various project delivery methods available to the
Village for project execution.
7.2.1
Design-Bid-Build (DBB)
Design-Bid-Build is the most common and widely used project delivery
method in the United States. The process involves executing the project in
three sequential phases: Design, Procurement (Bidding), and Construction.
The designer prepares the construction plans and specifications for use
in the procurement process. For the Village’s undergrounding project,
the construction documents will consist of drawings and specifications
prepared by Kimley-Horn, FPL, AT&T, and Comcast. The project is then
advertised for public bidding and price proposals are obtained from
interested members of the contracting community. The Village is familiar
with this process and has standard contracting language developed to
execute construction projects using this delivery method. The selection
process is usually the lowest responsive and responsible bidder under
this delivery method. The contractor who submits the lowest price, has
demonstrated it meets the minimum qualifications set forth in the bid
documents, and has properly prepared the bid proposal package per the
instructions, will be awarded the project.
Disadvantages:
The Village generally faces exposure to contractor change orders
and claims over changes and unknown field conditions since the
Village accepts liability for design in its contract with the contractor.
This approach can create a more adversarial relationship between
the involved parties rather than a cooperative one. This can lead
to higher costs and longer schedule durations than originally
anticipated.
The process may have a longer duration when compared to other
delivery methods since all design work must be completed prior to
selection and award of a construction contract.
The absence of a contractor during the design process does
not allow for the advantages a contractor may provide through
assessment of scheduling and cost ramifications for various
elements of the design.
If the Village uses a fixed price contracting method, the contractor
may pursue a lowest-cost approach to completing the project
and the Village may receive lower quality work than expected for
the price, requiring increased oversight and quality review by the
Village and design team. If the Village uses the unit price bidding
and compensation method, the contractor may try to increase the
scope to maximize revenue from the contract, costing the Village
more than expected.
The absence of construction input into the project design may limit
the opportunities for building in efficiencies that can reduce the
cost and duration of the work. Important design decisions affecting
both the types of materials specified and the means and methods
of construction may be made without full consideration from a
construction perspective.
The following is a summary of the advantages and disadvantages of the
DBB project delivery method:
Advantages:
This method is the most common approach for public owners
having to comply with local, state or federal procurement statutes.
The Village’s Procurement department already has standard
contracts and guidelines in place to facilitate this method.
This method is well understood by the Village and has well-
established and clearly defined roles for the parties involved.
This method can yield a low upfront cost to construct the project
because much of the risk is assumed by the Village and design
plans and specifications are well defined.
The Village has a great degree of control over the process due to
their control over many elements of the design prior to selection
of the contractor. However, the Village exerts less control over the
designs prepared by FPL, AT&T, and Comcast or to changes to
the design these entities may choose to make after the bidding
process.
