This editorial generally takes a reasonable point of view. However, the problem with the City Center Guideway and Stations segment isn't the "engineering challenges." It's the right of way and access issues that have plagued the project all along. Inability of the contractors to gain access to where they need to work (including relocating utilities) is the biggest impediment to maintaining the project schedule, not performing the work itself. If Robbins is serious about risk management, he will focus on this problem first and foremost.
