  1. Sea-to-Sky Highway Improvement Project INRC 5th Engineering Conference September 20th, 2011 Grant Lachmuth, AScT, RTMgr– Senior Project Director

  2. The Sea-to-Sky HighwayVancouver to Whistler Metro Vancouver • Population 2 million • Host city of 2010 Winter Olympics

  3. The Sea-to-Sky HighwayVancouver to Whistler Whistler • Host Mountain resort for Olympic and Paralympic games • 10,000 Permanent residents 4,000 Seasonal residents • 1 Million winter visitors • 1.6 Million summer visitors • Whistler is responsible for 17% of BC’s Tourism industry

  4. Corridor overview Whistler

  5. ProjectGoals Improve Safety Reliability Capacity / Mobility Duringconstruction Minimize delays & closures Maximize predictability Completion 2009 On time & on budget

  6. Construction Challenges

  7. Building additional lanes down slope Before Construction After Construction

  8. Building additional lanes down slope

  9. Context Sensitive Design Making the highway look “like it belongs”

  10. Procurement • Three distinct stages • The “Test Section” • Design Build Sections • P3 - Design Build • Finance Operate • Contract (DBFO)

  11. Stage one -Test Section • 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

  12. Stage two - Design Build Sections • With the hard deadline of the Olympics, DB contracts allowed work to continue during the P3 procurement process • Sunset Beach to Lions Bay – 7 km • Four lane section completed 18 months ahead of schedule

  13. Stage three P3 (DBFO) P3 - DBFO Goals: • Build and design at the same time • Synergy with builder and Maintainer • Project wide traffic management

  14. 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

  15. The P3 Competition Traditional ContractSea to Sky P3 Owner sets Owner sets Scope Budget Schedule Bidding contractor provides Bidding contractor provides ? Price ? Schedule ? Scope

  16. 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

  17. 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

  18. Result: $131 Million dollars worth of additional improvements over typical procurement Winning bidder Sea to Sky Transportation Group Province of BC DBFO Agreement Equity O & M Contract Debt DB Contract

  19. Additional improvements over typical procurement • Median Barrier • 20 km baseline median barriers • 16 km of additional median barriers provided (80% more)

  20. Additional improvements over typical procurement • Passing Lanes • 60 km baseline passing lanes • 20 km of additional passing lanes provided (33% more)

  21. Additional improvements over typical procurement • Rumble Strips • 44 km baseline shoulder and centre-line rumble strips • 30 km of additional rumble strips (68% more)

  22. Additional improvements over typical procurement • HRPM Lines • Additional highly reflective pavement markings

  23. Additional improvements over typical procurement • Wider Shoulders • 58 km baseline wider shoulders • 10 km of additional wider shoulders (17% more)

  24. Construction Highlights 48 Bridges & Interchanges

  25. Construction Highlights • 219 Mechanically • Stabilized Earth • Retaining Walls • (74,200 m2) • Approximately 10 km

  26. After Construction Before and after Before Construction

  27. Completed on Budget and ahead of Schedule
