About this file
This is Addendum 6 to RFP 197F-24 issued by the Massachusetts Bay Transportation Authority (MBTA) and Massachusetts Department of Transportation (MassDOT) dated February 12, 2025. The addendum adds Section 4.13 Contract Bid Option #9 for Axle and Wheelset overhaul services, which includes requirements for new 40" AAR E-40 wrought steel wheels, axle inspections, and comprehensive material documentation. The scope encompasses inspection, reconditioning, and new wheels per technical specification VE-23-055 section 4.13, with a quantity of 80 units to be exercised within 30 days of NTP. The contractor must provide material reports including mill test reports, heat treatment records, dimensional inspections, hardness tests, NDT records, and material origin documentation.
The addendum updates the options table to include nine total options, ranging from ECU system upgrades to locomotive decommissioning. Option quantities vary from 1-80 units depending on the scope, with exercise periods typically within 30 days of NTP, except for Option 5 (240 days) and Option 7 (within 1 year). Hidden damage provisions are included at the Authority's discretion for additional units beyond the base scope. The RFP price proposal (Attachment 6) will be issued as Revision B to reflect these changes.
