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 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
