PracticeDefinition of PBES

PBES consists of bridge structural elements & systems that are built off the elements & systems that are built off the bridge alignment to accelerate on-site

t ti ti l ti t ti l construction time relative to conventional practice.

PracticeBenefits of PBES

Significant advantagesReduced on-site construction time– Reduced on-site construction time

– Minimized traffic disruption – months to days– Reduced environmental impact– Improved work zone & worker safety– Provides positive cost-benefit ratios when user costs

are consideredare considered– Improved product quality – controlled environment,

cure times, easier access, etc.

Review

Why does innovative contracting support ABC?

Innovative contracting compliments ABC by allowing the contractor to work directly with the g ydesigner on constructibility and risk sharing.

Review

What is the major reason owners are choosing ABC?

Minimize impacts to the traveling public.
