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)
slide13
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
slide14
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
slide15
Stage three P3 (DBFO)

P3 - DBFO Goals:

  • Build and design at the same time
  • Synergy with builder and Maintainer
  • Project wide traffic management
slide16
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
slide19
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
