The Jacques Cartier Bridge is a fivelane bridge approximately 3.4 km in length, spanning the St. Lawrence River between the cities of Montreal and Longueuil. It services approximately 43 million vehicles annually.

The project consisted replacing the existing deck with prefabricated panels, a project evaluated at over $125M, this is the most significant restoration project ever undertaken on a Canadian bridge.

The deck is 2.7 km long and approximately 23 m wide, totalling 62,000 m2. The new deck was constructed of precast, prestressed and post-tensioned panels made of high performance concrete which were prefabricated. Exactly 1,680 prefabricated panels were installed.

A study indicated that 90% of the bridge use occurred between 5:30 am and 8:30 pm; in order to minimize the impact on users, the restoration work was carried out at night.

Occurring during the 2001 and 2002 construction seasons, this was a design-build project involving a twostage tendering process and the prequalification of contractors.

The main challenges of the project were to:

• Preserve uninterrupted traffic during the rush hours for vehicles, cyclists and pedestrians.
• Maintain uninterrupted navigation over the seaway.
• Uphold the numerous public utility services.
• Sustain services necessary for the operation of the bridge, lighting, signage etc.
• Protect the environment.

Revay and Associates was mandated to prepare the tender documents in collaboration with the professionals and specialists retained by the owner. These documents include:

• Contractor Pre-Qualification
• Instruction to Bidders
• General Conditions
• Supplementary Conditions
