Use of Innovative Project Procurement as a Tool in Shaping the Design of Underground Megaprojects for the Crenshaw LAX Light Rail Transit Corridor Project in Los Angeles, California

摘要

The Crenshaw/LAX Transit Corridor Project is a $2.058 Bn. transportation infrastructure projectrnthat used a single Design/Build (DB) contract to procure a 13.5-km (8.5-mi) light rail transit line including twinrnbored tunnels, cut and cover tunnels, three underground stations, one elevated station, four at-grade stationsrnas well as aerial guideway and bridge structures over major thoroughfares. The paper provides a summary ofrnthe procurement approach, from development of bridging documents, leveraging the proposers’ alternativerntechnical concepts, and the resultant design approach.
