Procurement
Three distinct stages
1. The “Test Section”
2. Design Build Sections
3. P3 - Design Build Finance Operate Contract (DBFO)
13
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
Stage one -Test Section
14
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
15
Stage three P3 (DBFO)
P3 - DBFO Goals: Build and design at the
same time
Synergy with builder and Maintainer
Project wide traffic management
16
P3 - Fixed Payment Schedule
Payment schedule includes:– Construction– Rehabilitation– Maintenance
Province fixes payment schedule so all bidteams know how and when they will be
paid

Bid competition based on additional safety improvements - not price
Teams challenged to exceed baseline requirements
The P3 Competition

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
