2. Presentation Topics • Program overview. • S. Massachusetts to Union Electrical Line Relocation. • S. Holgate to S. King Street Viaduct Replacement. • Central Waterfront Replacement. • EIS. • Alignment. • RFP.

3. Program Overview • Governor and Mayor signed a Memorandum of Agreement endorsing the bored tunnel in October. • Electrical Line Relocation Project to be substantially complete in early December. • Holgate-to-King design modifications: estimated $100 million in savings. • Two SR 99 ITS contracts advertised in October; bids opened on one.

4. Program Overview • Central Waterfront bored tunnel alternative: • CEVP + VE workshops results in new alignment option. • EIS schedule impacted by new alignment; requires aggressive approach to maintain schedule. • SOQ’s received from four teams; evaluations in progress. • Estimate-at-Completion: recent CEVP and estimate results - • Bored Tunnel Alternative = $2,000 million. • Holgate-to-King = $ 443 million. • Other Moving Forward = $ 365 million. • TOTAL STATE = $2,808 million. • Current Legislated Budget is $2.4 billion. Need $400 million in Toll Revenue Bond proceeds needed to deliver State scope.

5. Program Overview • Schedule highlights: • Holgate-to-King: • New conformed bid set with re-design in February 2010. • Bid opening on March 24, 2010. • Bored Tunnel Alternative: • RFP draft complete: February 2010. • ROD in Spring 2010.

6. Electrical Line Relocations • Recent Activities: • Transmission Circuit #1 was cut and distribution was turned over to SCL for splicing. • Transmission Circuit #2 testing/energization and Royal Brougham Way asphalt restoration was completed. • Demolition of old oil contained cable system from viaduct has been completed. • Distribution lines are being removed. • Facility has been turned back to SCL. WSDOT providing support to SCL to repair an oil leak vicinity University / Western. • Forecast to be substantially completed in early December.

7. Electrical Line Relocations Demolition of Existing Electrical Cables under Viaduct Emergency Oil Leak Location & Repair

8. Holgate-to-King Viaduct Replacement • Recent Activities: • Stage 1 (Construction) • New bike and pedestrian path was opened to the public. • Completed 26kV duct bank from Station 2+25 to Station 6+13. • Began contract work north of Royal Brougham Way • Stage 2 (Design). • UPRR and BNSF Whatcom Lead vacation agreements and the BNSF Railroad Construction & Maintenance agreement were finalized. • Contract advertised on October 26, 2009.

9. Holgate-to-King Viaduct Replacement • Recent Activities: • Stage 2 (Continued) • November VE studies resulted in design change recommendations that would: • Remove retained cut undercrossing and associated bridges. • Replace undercrossing with an elevated structure that will for Port traffic to bypass the railroad crossing (a new Stage 3 contract). • Provide for detour through WOSCA, replacing the west side transition structure connection to the viaduct • Above design revisions result in EA re-evaluation to be completed before March 24, 2010 bid opening date.

10. Holgate-to-King Viaduct Replacement • Challenges & Opportunities: • Reaching agreement on Railroad pre-emption at Atlantic Street with City and BNSF. • Completing Stage 2 design changes and not delay bid opening past March 2010. • Recent design changes result in estimated $100 million savings and reduced construction duration by an estimated six months.

13. Holgate-to-King Viaduct Replacement 26kV Electrical Duct Bank between Ring Vaults 1 and 2 Setting Overhead Poles at Port of Seattle Terminal #46

14. Central Waterfront / Bored Tunnel Alternative EIS • Recent Activities: • Held cooperating agency EIS review kickoff meetings with the Port of Seattle and King County. • Completed the first and second rounds of co-lead agency reviews of several discipline reports. • Developing a revised SDEIS schedule given recent changes to north and south portals. • Upcoming Activities: • Continue development and co-lead review of SDEIS summary chapters, outline, and selected appendices. • In January, receive and utilize a revised EIS design snapshot. • Target for Record of Decision is Spring 2011.

15. Central Waterfront / Bored Tunnel Alternative EIS • Challenges & Opportunities: • Meeting the aggressive EIS schedule relies heavily on quick reviews and issue resolution, close coordination with co-lead and cooperating agencies, and aggressive 106 and ESA consultations. Many items are on the critical path.

16. Central Waterfront / Bored Tunnel Alternative RFP • Recent Activities: • Latest contracting strategy calls for tunnel bore to be design-build; all other packages will be design-bid-build. • Geotechnical investigation program will result in a Geotechnical Baseline Report. Key to risk management and will accompany the tunnel bore RFP. • Bored Tunnel Alternative draft RFP is in review, to include reviews conducted by the City of Seattle. • Issued a RFQ to which four teams have submitted SOQ’s

17. Central Waterfront / Bored Tunnel Alternative RFP • Upcoming Activities: • Evaluate the four SOQ’s received in December; develop a short-list. • RFP schedule: • Draft RFP complete: February 2010. • Final RFP complete and issued: June 2010. • Proposals due to WSDOT: October 2010. • Award of the design-build contract: January 2011.

18. Central Waterfront / Bored Tunnel Alternative RFP • Challenges & Opportunities: • Developing a final RFP for a design-build contract that will remain attractive to proposers. • Balance risk between WSDOT and proposers in a way that is in the best interest of the Department.

19. Central Waterfront / Bored Tunnel Alternative Alignment • Recent Activities: • CEVP and VE workshops held to maximize efficiencies and reduce costs. • Selected a new alignment option (see diagram next page). • Initiating utility investigations along the new alignment option and addressing right-of-way and building settlement impacts. • New alignment in the north removes the need for construction of the detour for SR 99 and the temporary structure on Harrison Street over SR 99. • Developed south end Preliminary Construction Staging concepts, and updated identified tie-back, staging and acquisition areas.

20. Central Waterfront / Bored Tunnel Alternative Alignment

21. Central Waterfront / Bored Tunnel Alternative Alignment • Upcoming Activities: • Conduct additional geotechnical investigations along the new alignment option. • Continue with utility relocations; determine right-of-way needs; assess building settlement risk and mitigation measures. • Document the new alignment option as the baseline against which to manage project delivery. • Challenges & Opportunities: • Complete the design snapshot reflecting the new alignment option so as not to impact the EIS and RFP schedules. • Deliver the overall bored tunnel alternative to an aggressive schedule that opens to traffic in 2015.
