Davis Langdon was commissioned in fall 2005 as sub-contractor to Burns Engineering, one of the Program Management Oversight Contractors (PMOC) for the Federal Transit Administration (FTA), to assist originally with risk analysis services and more recently expanded to include cost forecasting, scheduling and estimating services on the Portland South Corridor Light Rail project.
The South Corridor Light Rail Extension entails the addition of two new line segments to the existing Banfield line of the light rail system in Portland, Oregon. The first section includes the addition of about 6.5 miles of double line track along the I-205 corridor, while the second section provides an additional 3.4 miles of single line track through the downtown Portland Mall. A total of fifteen new stations are included in the extension plan. The project encompasses all design, procurement, and installation of all utility relocations, civil works, structures, guideway, track, signal, communications, traction power, overhead catenary, life safety work and system, and real estate and easement acquisitions to support the extension of the existing light rail system. The project also includes 21 additional light rail cars to support the new line service, as well as expansion of the existing operations center and maintenance facility to provide necessary storage, maintenance and operational capacity to support the new cars and new track.
Size:
About 10 miles of new track, and 15 new stations
Construction Cost:
$557 million
Status:
Current schedule has service resuming in July of 2009
The new program risk assessment process projects required contingency at strategic milestones throughout the life of a project and ensures mitigation is developed early ensuring adequate ‘triggered’ contingency is available to complete the project to budget.
On each of the projects Davis Langdon prepares detailed risk registers, program level models and contingency plans, detailed quantified cost and schedule Monte Carlo models. Our role includes facilitation of workshops and leading the multidiscipline teams through to report production.
Davis Landon’s role also includes liaison with other consultants and PMOC’s attached to the PMOC risk assessment program, in order to develop procedures, discuss report formats and adjust methodology as the process develops and matures.
