This was a complex project, so it was important that the design-build design accounted for what the BART stakeholders needed, and that the contractors understood their role. Proactive discussions with the contractor and BART, and an approach that involved working in the BART offices, helped us with problem identification and resolution. Personnel consistency helped to keep the owner informed and the project on track.
