One of the key differentiators of the various delivery methods The decision as to when the
contractor agrees to a figure and the resulting responsibilities of the contractor
Project delivery methods Design bid build, construction management, design build
Design bid build Involves linear design sequence, set of construction documents which
contractors submit fixed-price bids. Lowest bidding contractor is usually selected to build the
project.
Negotiated team Negotiated select team involves early selected contractor and or
subcontractors , contract terms such as overhead and profit multipliers determined prior to
completion of the construction documents.
Portions of the building that may be particularly difficult to fabricate or construct may be
accelerated under the negotiated select team approach The selected contractor may be
available for consultation regarding construction issues during design.

Cost-plus fee Contractor selected at the completion of construction documents, but the
scope of construction is unpredictable.
Under a cost plus fixed fee contract, the contractor is paid actual labor and material costs for
construction plus a fee for coordination of trades Incentives may be added to the fee if the
project finishes early or under the original budget.
Owners have increasingly demanded detailed construction and technical advice earlier in the
design process The construction community has accommodated this need by creating the
field of construction management
Three construction management roles Advisor, agent, constructor
Construction management advisor Acts as a constructibility and cost management
consultant during the design and construction process, does not construct a building.
Construction manager agent Provides early consulting and may act on behalf of the owner
in assembling and coordinating the construction trades prior to and during construction.

Construction management agents typically provide their services for a fixed fee and assume no
risk for the actual construction costs, pass on savings and overruns directly to the owner.
CM agent is authorized to enter into contracts on behalf of the owner, advisor is not.
Construction management constructor Technical and cost advisor role of the contractor
during the project design phase transitions at a point to the role of contractor for the project
Construction management constructor frequently use guaranteed maximum price This is a
commitment by the construction manager to build the project for a specified price developed
from design documents, typically at design development.
Inherently difficult role stems from construction manager acting as contractor and estimator
Cost decisions made early in design directly affect the construction managers cost and
profitability later in construction.
Design build delivery method provides the owner with a single point responsibility for both
design and construction Emerged from owners dissatisfaction with tensions and conflicts
between architects and contractors

One problem with design build is the mechanism by which the owner establishes and enforces
the performance and quality parameters of the project This role was typically assumed by
the architect as an agent for the owner separate from the contractor.
Bridge design build is a variation of design build which addresses the owner representation
problem Bridge design build employees : a design architect reestablishes the design
concept and a production architect who determines technical criteria and generates construction
documents.
In bridging, the owner eventually hires to Architects, one of which is part of a design build team
The first Architect prepares a preliminary design for a building and performance
specifications, detailed criteria to which the ultimate design must conform
The completed concept and criteria package, based on design development drawings and
specifications Is then tendered to design build teams that offer both technical architecture
and construction capabilities.
Guaranteed maximum price approaches to construction cost Establishment of a
guaranteed maximum price suggests a commitment by the owner and construction manager
contractor to a cost based on a partially complete set of design documents.
