Context Sensitive Design

Making the highway look

“like it belongs”


Procurement

Procurement

  • Three distinct stages

  • The “Test Section”

  • Design Build Sections

  • P3 - Design Build

  • Finance Operate

  • Contract (DBFO)


Sea to sky highway improvement project

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


Sea to sky highway improvement project

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

Stage three P3 (DBFO)

P3 - DBFO Goals:

  • Build and design at the same time

  • Synergy with builder and Maintainer

  • Project wide traffic management


Sea to sky highway improvement project

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

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

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

Result: $131 Million dollars worth of additional improvements over typical procurement

Winning bidder Sea to Sky Transportation Group

Province of BC
