"As one of our prime contractors, Breda Costruzioni demonstrated their ability to successfully manage a complex contract with numerous sub-contractor activities involved. Breda was responsive to MTA's needs and their efforts to maintain a high-level of quality assurance and systems support was outstanding. In addition, they supported MTA in its efforts to open its inaugural Red Line subway system eight months ahead of schedule. Lastly, Breda successfully completed the base-buy procurement of 30 passenger vehicles that were in compliance with all design and performance specifications. These vehicles have been in satisfactory revenue service since January 1993."
