Construction Industry Efforts and Capabilities to Support PBES
Deployment.
William G. DuguayJ.D. Abrams, L.P.
Learning Outcomes
• Current market conditions• Efforts under way to support PBES• How other industries do their version of ABC• Barriers to implementation• Why this should be good
Section 1How Current Market Conditions
may Affect ABC and PBES
Current Market Conditions and their Effects on:1. Lower Bid pricing2. Overall Lower Bid Volumes3. Growing International presence
• Will continue to drive:– Adaptability– Innovation– New/modified uses for existing equipment– Bringing new companies into every market– Acceptance of European, Asian technology
An estimated 146,000 bridges need work
• Every Agency is strapped for funding, and are looking for:– New funding streams– New delivery methods– New designs– Raising expectations of performance
Section 2Industry Efforts to Support PBES
• What are some of the industry efforts under way to support PBES?– Adaptive use of technologies in other industries– Collaboration with Universities for research– Industry Outreach and Transportation Forums
Major Markets served by the Heavy Lift Industry
• Oil & Gas• Nuclear Power• Fossil Power• Wind Energy• General Construction• Heavy Civil• Project Cargo Logistics
Other Industries are used to moving modular units
Efforts underway to support PBESBay Bridge East End Tie In

Bay Bridge West Tie in
Pioneer Crossing, UT
Scaled for everyday use
Pieces can be scaled to adapt to conditions and needs
Precast segmented abutment
Precast columns, caps and abutment
PBES Doesn’t have to be Huge
PBES can be something other than steel or concrete
HCB Bridge Elements erected using standard equipment
Adaptive reuse of Technology and Equipment
Marino Proposed Concept
International Technologies
Industry is working upstream and downstream
Industry Supported ResearchUniversity of Washington
Working with a Highways for Life Contract, a simple footing detail was developed: “It has definitely been a team effort, with people from all the necessary disciplines actively involved” This included WSDOT, local AGC members and local engineering firms
HCB Laboratory Validation
Earthquake testing SUNY Buffalo
Precast Overhangs
From Design, to Lab to Production
Transportation Forums
• Fast 14 in Massachusetts $78M now underway• Columbia River Bridges $3.6B• Tappan Zee Bridge $8-16B• Ohio River Bridges Project $4B• Epping bridge replacement
Section 3Is ABC/PBES unique to
Transportation?
Adapt Delivery methods from other industries: Manufacturing and Commercial Buildings
version of ABC:
• Lean Construction– Do more with less– Bring Manufacturing Principles into Construction, focus on
the cycle from identification of need thru delivery– Each step of the process is monitored and improved– Maximize field safety, quality and productivity
• BIM going horizontal
Section 4What could the barriers to
Implementation be?
Projects don’t need to be huge
• Contractors and Vendors participate in design and constructability reviews for projects of every size
• Local meetings emphasize local abilities, drawing on national resources when needed
Other perceived barriers
• Lack of agreement on need for new methodology
• Is the Risk suitable for the Reward• Is the new method going to be part of the
Agencies policy going forward• Does the bridge portion drive the overall
critical path• Will money spent on PBES be at the expense
of other portions of an Agencies Program
Each of these barriers can be resolved thru communicating
the goals of the project• The Transportation Industry has many
successful projects of:– Varying dollar size and local– Type of construction and delivery– That solved unique needs effectively
Section 5Why ABC and PBES can Benefit
Industry
2 Ways
• Maximizing the Delivery Process PBES can allow:– Significant bridge work activities be moved off of
the Critical Path– Them to be moved out of traffic– These activities be consolidated and reduced to
minimize the impact on the community– Safety, quality, durability, adaptability of our
Infrastructure be a larger part of our message
2nd: Our Industry Competes for Funding
• Transportation needs are well known• As Funding becomes available, the traveling
public will not allow extensive added congestion due to these improvements
How do we improve the highway system to a level of quality the public expects in a timely fashion?
• Do as much as possible at times and in locations that minimize interference
• Where that’s not an option, do those portions as safely and as quickly as possible
• By using PBES in appropriate situations, we can effectively demonstrate how adaptable the Transportation Industry is, to: – Maintain the value of our nations transportation
investment– Continue to improve the effectiveness of our
system to provide safe and reliable transportation at the local and national level
