Because the design parameters of a project are being developed along
with the budgetary goals construction methodologies and budget conditions
being weighed simutaneously, a project is more likely to be realized
than with pure design approach. The owner has greater access to
the "team" working on project developement as the project
is being developed. This efficiency is not a negative "short
cut" as a rule, but rather the keystone to the success of the
Rather than a parcelized level of responsibility of the classic
design-bid-build, design-build provides an integrated solution for
the owner or client. This moves projects away from the "finger-pointing"
that is often commonplace in contemporary construction projects,
and allows the owner to look to one entity with any questions or
Instead of having several contractors and consultants, an owner
has just one entity to deal with. Design revisions, project feedback,
budgeting, permitting, construction issues, change orders, and billing
can all be routed through the design-build firm. This single point
of contact allows a certain degree of flexibility for the owner.
Most design-builders will leverage that flexibility for the owner's
benefit by continually refining the construction program to maximize
the owner's value at the completion of the project.
Typically, in order for a contractor to bid on a project, very specific
details relating to the methods and materials must be given to avoid
any ambiguity and to make an "apples to apples" comparison
of bids. In a design-build context, the owner, the owner's other
consultants, and the design-builder can work together to determine
what methods and materials will maximize the owner's value. In instances
where marginally more expensive materials, designs, or construction
methods might yield a higher return on investment for the owner
than those of lower cost, the owner is free to adjust the project's
program without having to re-bid the entire project.
Almost 70% of traditional contracts end up over
budget, compared to D&B which is only around 25-30% over budget.
The overage of a D&B project is generally owner driven whereas
the overage in the more traditional method tends to be a result
of the budget disconnect to which many architects and other design
professionals are prone.
