Abstrakt:

Signature on the Saint Lawrence Construction (SSLC), a consortium comprised of SNC-Lavalin inc., Flatiron Constructors Canada, Dragados USA and EBC, is mandated to build the New Champlain Bridge Corridor Project (NCBCP). Significant challenges include:

  1. Construction schedule: The Bridge must be in service by December 2018.

  2. Navigation restrictions: The Seaway traffic must be maintained during the main span’s construction.

This paper discusses the following innovative construction methods used for the New Champlain Bridge (NCB):

  1. A custom-built gantry to install the precast footings/pier starters in the river;

  2. The delivery system for the segments to the tip of the deck in the main span.

These erection systems were developed and selected to suit the specific challenges of the project, including speed of construction, maintenance of shipping and environmental protection areas.
