OTIA III State Bridge Delivery Program – Construction Waste Management

1. OTIA III State Bridge Delivery Program – Construction Waste Management Geoff Crook Environmental Program Manager Major Projects Branch

2. Overview • OTIA III program background • Sustainability and environmental stewardship • Construction waste management • Purpose and Goals • Tools and Resources • Reuse and Recycling Targets • Materials and Targets • Implementation • Successful results • Findings and lessons learned

3. Program background • Oregon Transportation Investment Act III. • $1.3 billion package to repair or replace 365 bridges on the state highway system. • Oregon’s largest investment in highway and bridge construction since the 1950s and 60s.

4. Sustainable solutions • A philosophy • A framework • A process

5. Environmental stewardship • Programmatic permitting with natural resource agencies — collaborative approach. • Environmental performance standards • Single set of terms and conditions. • Guidance to achieve program goals. • Flexible, outcome-based measures.

6. Environmental stewardship • Materials and contamination performance standard goals: • Achieve regulatory compliance. • Achieve consistency in materials management across the program. • Facilitate highest and best end use for all categories of construction waste.

7. Construction waste management • Responds to OTIA III program goals, CS³ and materials performance standards. • Builds upon the good work of contracting community. • Provides tools and guidance to contractors. • Collects a baseline of data to tell the whole story.

8. Tools and resources • Regional reuse and recycling targets. • Construction waste reuse and recycling plan. • Construction waste reuse, recycling and disposal form. • Construction contract special provisions language. • Construction Waste Management Resource Guide and Directory.

9. Reuse and recycling targets • What’s reasonable and achievable? • Looked at available facilities. • Distance to nearest facilities. • Input from stakeholders and facility operators. • Developed a regional approach. • Not a formal requirement. • Need baseline data to check feasibility of targets. • Will inform current and future materials management practices.

10. Materials and targets

11. Planning and reporting Construction waste reuse and recycling plan • Estimates material types, quantities and activities (reuse, recycling and disposal) for project. Quarterly reuse, recycling and disposal form • Reports actual material types, quantities and activities (reuse, recycling and disposal) for project.

12. Implementation • Developed contract special provisions. • Streamlined tools and process to provide consistency. • Addressed contractors’ concerns: • Bridge- vs. bundle-level reporting • Frequency of reporting • Estimating cost savings • Target levels • Held trainings and reviewed for continual improvement.

13. Summary of 2010 material reuse and recycling (tons)

14. 2010 estimated material values

15. Landfill diversion rates

16. Successful results On Bundle 215 near Eugene, ODOT salvaged 64 concrete beams for reuse on future bridges, saving a potential $1 million in materials costs and keeping more than 4,000 tons out of landfills.

17. Successful results On Bundle A02 near Eugene, two contractors exchanged 30,000 cubic yards of concrete rubble, avoiding waste, landfill costs and excavation of new materials. Eighty box beams were reused on three other detour bridges.

18. Successful results On Bundle 211 in Wilsonville, while replacing two bridges and performing pavement preservation on 22 miles of a six-lane highway, the agency kept 130,000 tons of asphalt pavement out of landfills.

19. Successful results ODOT transported about 300 felled trees from Bundle 401 in Elkton to the Umpqua River basin. The Oregon Department of Fish and Wildlife used them to restore two creeks as prime habitat for Coho salmon.

20. Successful results More than 700 whole logs were reused for habitat in the Sandy River basin after winter rains washed them downstream and onto work bridge piers in Bundle 210 near Troutdale.

21. Findings and lessons learned • Contractors are reusing and recycling more than 90 percent of construction waste generated. • Co-located projects in “bundles” have increased opportunities for materials reuse. • Data reporting has improved over time; however, it remains a challenge for some contractors. • Reported values often exceed those planned.

22. Findings and lessons learned • A bundle summary by contractor may have been more effective than a planning document. • Quality data capture requires ongoing education, training and contract enforcement. • Materials management needs to begin in design and carry through construction. • Tracking environmental outcomes is important to funding commitments and future program support.

23. Conclusion “…providing a prosperous and sustainable future for Oregonians.” Executive Order 06-02: Sustainability for the 21st Century Geoff Crook Environmental Program Manager Major Projects Branch (503) 986-3425 geoff.s.crook@odot.state.or.us
