City of Calgary's West LRT Project: Use of Design-Build for Fast Track Delivery

摘要

Revenue service for Calgary's $1.4 Billion West LRT project was achieved on December 10, 2012, only five years after City Council approval to proceed with the project. The success in achieving this milestone was largely due to effective planning by the Owner and implementation of a design-build model for fast track delivery of the core components, these included a new 5 mile line with elevated, tunneled, trenched and at-grade guideway, 6 passenger stations, 11 substations and utility buildings, a new highway overpass and 2 new park and ride facilities. Award of the design-build contract to SNC-Lavalin Constructors Pacific (SLCP) was made in November 2009, with a 37 month design and construction schedule utilizing a combination of prescriptive and performance specifications to facilitate integration with the existing LRT system while also allowing some innovation where appropriate. This paper will present the Owner's rationale for proceeding with design-build delivery and how public and organizational considerations were addressed. This paper will also present an overview on some key lessons learned from the City of Calgary's perspective.
