15. Stage One – Test Section







Traditional construction contract
0.9 km in length
Started in 2003
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
Cost was $4M

16. Stage Two – Design-Build
Sections
With the hard deadline of the
Olympics, DB contracts
allowed work to continue
during the P3 procurement
process.
Design-Build 1

18. Why Design-Build?
•
•
•
•
•
•
Unknown level of Geotechnical
risk.
Significant traffic management
issues
Environmental concerns
Early project estimates = $1.0B
Treasury Board allocation =
$600M
Feasibility of downslope

19. Stage Three – P3 (DBFO)
P3 - DBFO Goals:
 Build and design at the
same time
 Synergy with builder and
Maintainer
 Project wide traffic
management
 Project must begin
construction in 2005 and
be completed in 2009
 RFEOI – 2003
 RFP – 2004
 Proposal Evaluation and
Award in late 2004

20. 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.

22. 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

23. 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.
