Over 130,000 bridges Over 130,000 bridges recommended for recommended for replacement, ~$70B+replacement, ~$70B+
What is Driving the Change What is Driving the Change from Conventional from Conventional Construction?Construction? The infrastructure is aging needed
now are innovative solutions that canbe built quicker and that last longer
Goal: A minimum 75-yr service life Currently: Average bridge life is 42 yrs Average bridge deck life is 20-25 yrs

A Suggested Role for You
Insist on consideration of innovativetechnologies to accelerate construction9 Be willing to specify the first use9 Select a large project or multiple projects
with repetitive sections for the first use9 Use contracting strategies that are
significant to the contractor9 Include cost trade-offs in project estimate9 Engage all stakeholders for their input,
