Origins of SCI

The origins of SCI begin with a company named W.A. Stephenson Construction (Western) Ltd., formed 1977. The founding owners of that company include the current President and CEO of SCI.

Noteworthy projects included construction of segments of the transit systems in Calgary, Edmonton, and Vancouver, the Cambie Street Bridge (at the Expo 86 Site) in Vancouver, and the 1988 Olympic Speed Skating Oval in Calgary.

Throughout this period, we earned a reputation for delivering the highest quality, on-time, and with innovative thinking. Projects completed prior to 1993 were executed by one of the W. A. Stephenson / SCI Engineers & Constructors Group of Companies.


In 1985 growth and expanding market opportunities created corporate re-organization. SCI Engineers & Constructors was established to undertake the construction of large infrastructure projects, particularly in the United States.

Major segments of the Downtown Metro Transit Project in Seattle (four underground stations and cut/cover tunnel segment) and the Windward Viaduct (1.25 mile long, 4-lane elevated highway skirting the mountainous hillsides) near Honolulu, Hawaii were constructed.

In Canada, a major presence in infrastructure development continued, including the building of the Oldman River Dam in Alberta (main dam and drainage tunnels) and the Cassiar Connector Project in Vancouver (six bridges and major cut/cover tunnel).

Both of these projects were among the largest contracts ever awarded by the Province of Alberta and the Province of British Columbia. The success of these major projects earned the company a well-deserved reputation for its skills and abilities.


In 1988 a new, special purpose corporation, Strait Crossing Inc. (SCI), was established to undertake the renowned Confederation Bridge Project.

Nearly all the senior staff of W.A. Stephenson and SCI Engineers & Constructors were transferred to lead the complete financing, design and construction of this major project.

This project was successfully completed, and received in excess of 20 national and international awards, for engineering and environmental innovation and excellence, including being recognized nationally as one of the top five (5) Canadian engineering achievements of the 20th Century.


Since 1998, SC Infrastructure, a name that reflects our past experience, our expanded scope, as well as our focus on the future, has been dedicated to providing well structured and commercially viable solutions for needed global infrastructure.
