SEA-TO-SKY HIGHWAY IMPROVEMENT PROJECT 15
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
Stage One – Test Section
SEA-TO-SKY HIGHWAY IMPROVEMENT PROJECT 16
With the hard deadline of the Olympics, DB contracts allowed work to continue during the P3 procurement process.
Stage Two – Design-Build Sections
Sunset Beach to Lions Bay – 7 km
Started in 2004 Est. was $70M
Design-Build 1
SEA-TO-SKY HIGHWAY IMPROVEMENT PROJECT 17
Four lane section within DBFO
Started in 2004 Est. was $40M (act.
$35M) Complete 18 months
ahead of schedule
Stage Two – Design-Build SectionsDesign-Build 2
SEA-TO-SKY HIGHWAY IMPROVEMENT PROJECT 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

SEA-TO-SKY HIGHWAY IMPROVEMENT PROJECT 19
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
Stage Three – P3 (DBFO)
SEA-TO-SKY HIGHWAY IMPROVEMENT PROJECT 20
Payment schedule includes:– Construction– Rehabilitation– Maintenance
Province fixes payment schedule so all bid teams know how and when they will be paid.
P3 Fixed Payment Schedule

The P3 Competition
SEA-TO-SKY HIGHWAY IMPROVEMENT PROJECT 22
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 Competition
SEA-TO-SKY HIGHWAY IMPROVEMENT PROJECT 23
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.

Importance of balanced risk transfer Advantage of Test Section / DB sections for info gathering,
Environmental, Geotechnical and Traffic Management Project success lies in fostering positive working
relationships Need to be open to design change proposals Willingness to think creatively and innovatively. All project
