  • These before and after shots are a good example of some of the innovative down slope work that we’ve achieved.
    Despite the difficult terrain with steep mountain sides, a rail line below the highway and the Howe Sound below that - the project is on time, on budget and we will be ready to welcome the world to the 2010 Olympics and Paralympics
  • Thanks to innovative down slope construction techniques our contractor has been able make great progress and at the same time maintain the flow of people and goods on the Sea to Sky.
    The challenging down slope construction is almost complete.
    The toughest part of the project is behind us.
  • As these before and after pictures show the Sea to Sky will be a much safer and more enjoyable drive
    Improvements include safety features like median barriers, wider shoulders and rumble strips
  • Through some of the most difficult road building terrain in the world a greatly improved Sea to Sky Highway is quickly taking shape.
    Construction has been underway since 2003 and we are ahead of schedule with over
    70% complete
    85% mark will be announced at a Minister’s event end of Oct
    Improvements to the Sea to Sky include:
    Increased capacity
    Softer curves
    Better sightlines
    More median barriers
    Smoother grades
    Safer passing lanes
    Shoulder and centreline rumble strips
    And highly reflective pavement markings
    And this new multi lane highway will be much more reliable and easer to maintain especially in winter driving conditions.
  • I’ll be covering four elements in this presentation:
    Progress on improvements to the Sea to Sky highway
    Rock slope reliability program
    Alternative transportation routes
    And 2010 operations

    14. 14. Procurement 2003 2004 2005 2006 The “Test Section” est. $4M Design-Build Section #1 est. $70M Design-Build Section #2 est. $40M actual $35M P3 Design-Build-Operate-Finance (DBFO) 2007 2008 Fixed $455M Contingency Properties $36M 2009 TOTAL: $600M SEA-TO-SKY HIGHWAY IMPROVEMENT PROJECT 14
    15. 15. Stage One – Test Section        Traditional construction contract 0.9 km in length Started in 2003 Proving construction methods – so work can proceed faster and efficiently Addressing geotechnical issues – ensuring there are no construction surprises and budget increases Traffic management similar to overall project Cost was $4M SEA-TO-SKY HIGHWAY IMPROVEMENT PROJECT 15
    16. 16. Stage Two – Design-Build Sections With the hard deadline of the Olympics, DB contracts allowed work to continue during the P3 procurement process. Design-Build 1    Sunset Beach to Lions Bay – 7 km Started in 2004 Est. was $70M SEA-TO-SKY HIGHWAY IMPROVEMENT PROJECT 16
    17. 17. Stage Two – Design-Build Sections Design-Build 2     Four lane section within DBFO Started in 2004 Est. was $40M (act. $35M) Complete 18 months ahead of schedule SEA-TO-SKY HIGHWAY IMPROVEMENT PROJECT 17
    18. 18. Why Design-Build? • • • • • • Unknown level of Geotechnical risk. Significant traffic management issues Environmental concerns Early project estimates = $1.0B Treasury Board allocation = $600M Feasibility of downslope construction concept SEA-TO-SKY HIGHWAY IMPROVEMENT PROJECT 18
    19. 19. Stage Three – P3 (DBFO) P3 - DBFO Goals:  Build and design at the same time  Synergy with builder and Maintainer  Project wide traffic management  Project must begin construction in 2005 and be completed in 2009  RFEOI – 2003  RFP – 2004  Proposal Evaluation and Award in late 2004 SEA-TO-SKY HIGHWAY IMPROVEMENT PROJECT 19
    20. 20. P3 Fixed Payment Schedule  Payment schedule includes: – Construction – Rehabilitation – Maintenance  Province fixes payment schedule so all bid teams know how and when they will be paid. SEA-TO-SKY HIGHWAY IMPROVEMENT PROJECT 20
    21. 21. The P3 Competition SEA-TO-SKY HIGHWAY IMPROVEMENT PROJECT 21
    22. 22. The P3 Competition     Start with fixed price Fixed payment and construction schedules Bid competition based on: • additional safety • improvements - not price Teams challenged to exceed baseline requirements SEA-TO-SKY HIGHWAY IMPROVEMENT PROJECT 22
    23. 23. The P3 Evaluation   We would measure: • Safety (Crash prediction modeling) • Capacity • Traffic management Each criterion was weighed by its importance to the Owner and the winning bid delivered the highest level of safety, capacity and offered the least amount of traffic disruption.
