SNC-Lavalin Group Inc. (TSX: SNC), one of the world's leading engineering and construction companies, has expanded the use of Intergraph(R) SmartPlant(R) Enterprise engineering design and data management software to streamline operations, optimize work processes and increase productivity and profitability.

After a successful SmartPlant Enterprise implementation in its Nuclear division and months of intense evaluation, SNC-Lavalin enhanced its existing 3D CAD technology in its Light Industry and Mining and Metallurgy divisions, enabling true worksharing between regional offices and consortium partners and adding repeatable design flexibility to its projects. Standardizing on the Intergraph platform in the three divisions also will allow SNC-Lavalin to optimize resources, work processes and efficiencies due to the superior technology SmartPlant(R) Enterprise provides.

SNC-Lavalin is currently using SmartPlant software in partnership with Atomic Energy of Canada Limited (AECL) for the design of its new Generation III+ nuclear reactor ACR-1000, the upgrade of a Valero Refinery in California and other projects.

"Intergraph's breadth of integrated solutions and the availability of highly skilled local support were pivotal in our decision to expand our use of SmartPlant Enterprise products to help us achieve increased profitability through greater engineering efficiency," said Derek Pinder, manager of Engineering at SNC- Lavalin. "This expansion will continue as SNC develops new projects."

Gerhard Sallinger, Intergraph Process, Power & Marine president, said, "We look forward to entering into this new phase with SNC- Lavalin and to delivering new efficiencies and results across the entire company."
