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

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

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
