PracticeDefiniti on of PBES

PBES consists of bridge structural

elements & systems that are built off the

r ge a gnmen o acceerae on-s e

construction time relative to conventional

practice.

PracticeBenefits of PBES

Significant advantages – Reduced on-site construction time

– Minimized traffic disru tion months to da s

– Reduced environmental impact

– Improved work zone & worker safety

– Provides positive cost-benefit ratios when user costs

are considered

– Improved product quality – controlled environment,

cure times, easier access, etc.

Program EvaluationABC Because…

Value added to the public

Societal costs minimized

Public support for innovation

Political capital

List 3 important aspects ofimplementing program change.

Review

1. Research the innovation

2. Educate and engage the industry

3. Have a plan

What are key elements for

communicating with the public?

Review

1. Outreach programs

2. Messaging

3. Visual animation (Simplify the concepts)

What are three major c ategories of

accelerated bridge constructi on

Review

1. Foundation and wall elements

2. Rapid embankment construction

3. Prefabricated bridge elements and systems

4. Structural placement methods

5. Fast track contracting

What are the benefits of using ABC

and PBES?

1. Reduced on-site construction time

Review

2. Minimized traffic disruption – months to days

3. Reduced environmental impact

4. Improved work zone & worker safety5. Provides positive cost-benefit ratios when user

costs are considered

6. Improved product quality – controlledenvironment, cure times, easier access, etc.

Why does innovative contracting

support ABC?

Review

Innovative contracting compliments ABC by

allowing the contractor to work directly with the

designer on constructibility and risk sharing.
