Design/Build Faster Project Delivery, Cost
Savings, Public Safety
Unlike Design-Build, Retains Competitive Bidding, Protects Public
Interest
Designing-sequencing is an alternative method of contracting that is
safely delivering projects ahead of schedule and at a lower cost in
California. As the name suggests, design-sequencing allows the
sequencing of design activities to permit each construction phase to
commence when design for that particular phase is complete -- instead
of requiring the design for the entire project to be complete before
construction can begin.
In California’s
design-sequencing program, a contract for an entire project can be
awarded with plans that are as little as 30 percent complete, allowing
the contractor to work with state engineers to incorporate innovative
construction methods and designs to speed up project delivery and save
money.
Design-sequencing
holds a number of significant advantages over the design-build method
of contracting. Unlike design-build, design sequencing contracts are
competitively bid, ensuring that taxpayers receive the best price on
infrastructure and ensuring that transportation funds needed for other
projects are not wasted.
With
design-sequencing, state-employed professionals design and inspect
projects ensuring that public safety and the public interest are
protected. Conversely, with design-build projects, design,
construction and inspection are performed by the same consortium
producing a built-in incentive to complete work as quickly and as
cheaply as possible to generate profits.
To help you learn
more about design-sequencing and to facilitate its use in other
states, below are the California Department of Transportation’s
Design-Sequencing Guidelines, a report outlining design-sequencing
successes, and legislation implementing and expanding
design-sequencing in California.
