HIGHWAY 407 ETR - EXPRESS TOLL ROUTE GEOENGINEERING MANAGEMENT INNOVATIVE PROCEDURES

摘要

The design and construction of Highway 407 ETR - Express Toll Route in Toronto requiredrninnovative geotechnical management to fast track design and construction to meet the tightrnconstruction schedule. The Geotechnical Manager and Quality Control Manager had tornwork in an integrated manner to develop procedures as the design progressed so thatrnapprovals could be obtained on time.rnThe geotechnical management of the project included advance planning and identification ofrnproblems, value engineering, innovative applications and constructability reviews. Siternspecific solutions had to be found to meet limitations of time and budget.rnInnovative solutions for various elements of the project including materials, constructabilityrnand design from geotechnical perspective are described in this paper. Lack of adequaterngeotechnical information was compensated by close monitoring of the work duringrnconstruction. Cooperation between design, construction and QA/QC resulted in timelyrnsolutions to difficult situations.
