The Federal Highway Administration (FHWA) Tunnel Leak Assessment Team (A-Team) for the Boston Central Artery Tunnel (CA/T) Project was formed and activated in response to Administrator Mary Peters' request for an independent FHWA engineering assessment. The team arrived in Boston on December 19, 2004 and conducted the assessment from December 20-22, 2004. Background and technical materials were sent to the team for review prior to the team's arrival. The assessment consisted of an opening meeting with Division Administrator Stan Gee and his staff who briefed the team on the background and the current tunnel leak situation. This was followed by additional review of project documentation and a nighttime field tunnel inspection (to observe tunnel sealing operations and the inspection of wall panels). Interviews were conducted with 16 individuals from Bechtel/Parsons-Brinkerhoff (B/PB), Massachusetts Turnpike Authority (MTA), and the Federal Highway Administration Massachusetts Division (FHWA) (collectively referred to as The Project) who are currently or have been involved with the Project. A list of individuals interviewed and documentation reviewed by the Team is provided in the Appendix to this report. A closeout meeting was held with the Division Office on December 22, 2004. |
