Abstract

At CAD $1.54B, the Nouvelle Autoroute 30 project is the largest and second Public Private Partnership (PPP) transportation project procured in the province of Québec, Canada. It will operate as a tolled two-lane 42km divided highway with 31 bridges including two major bridge crossings of the St Lawrence River and Beauharnois Canal and a short tunnel. The project is located approximately 30km south-west from downtown Montréal and will relieve traffic congestion on Montréal Island by providing the final section of an alternative southern bypass route. The project is located in a seismic cold climate region and is underlain by deep deposits of soft sensitive Champlain Clay along much of the route. The ground engineering solutions engineered for the project include driven steel piles, drilled shafts and micro-piles, pile load testing, spread footings, earthworks (cuttings and embankments) including lightweight fill and surcharged embankments on soft clays with vertical drains as well as instrumentation and monitoring. This paper describes details of the geotechnical solutions designed and constructed on this major self-certification infrastructure project, and how by combining local and international experience the ground investigation, geotechnical design and construction certification were successfully delivered under this procurement method.
