THE DESIGN/BUILD METHODThe essence of the design/build concept is the idea that quality, completion dates and costs can be brought under
control by assigning total responsibility for all these factors to one single
entity: the design/builder.
Like the "master builders" of ancient times, the design/builder's
responsibilities span the entire building process, from conception through
move-in. To be effective, a design/build organization must combine strong
management ability with experience in balancing good design with construction
economy.
Here's how design/build works: The builder participates in the conception of
the project. He has designs, working drawings and specifications prepared and
then constructs the facility - all under a "single-point" responsibility
contract.
As the design/builder learns about the owner's expectations and requirements
with regard to size, function, quality, time and cost, he develops a building
program which includes a guaranteed maximum cost (GMAX). This GMAX is
established through input from the design/builder and owner as they develop a
list of needs that are then documented with drawings and specifications. The
design/builder develops a strong line of communication with the owner in order
to devise preliminary plans and definitions and set the tone for the working
drawings. This process establishes the scope of work which is the basis for the
Guaranteed Maximum Costs. The owner must insist on as much detail as he
requires for his wishes and needs to be satisfied.
The disadvantages of the traditional competitive bidding process are
eliminated, but the advantages of bidding are retained. When the owner and
design/builder work together on a "cost-plus" basis, materials and
subcontracted work are bid out competitively and all costs are fully disclosed.
The advantages of negotiating a GMAX instead of leaving costs to the vagaries
of the traditional bidding process are numerous. Costs are established at the
beginning of the project, and controlled from there forward.
