About this file
This is an addendum to a construction contract issued by the Maryland Transit Administration (MTA) for the Light Rail 5kV Signal Power Replacement project, designated as Contract No. T-1531-0350. The project involves the construction of new electrical equipment to replace the MTA Light Rail 5kV signal power distribution system for the Light Rail BWI Spur, extending from 373 Central Instrument House (CIH) to BW 115 CIH. The work encompasses eight locations where new electrical work will be performed (S373, BW 22, BW 46, BW 68, BW 84, BW 98, BW 104, and BW 115) and three locations where selective demolition only will occur without new electrical installation (BW 53, BW 56, and BW 77). The project is located across Baltimore City, Baltimore County, and Anne Arundel County in Maryland. This addendum represents a modification to the original contract terms and conditions established in the initial contract award.
The specific modifications, conditions, and requirements outlined in Addendum No. 005 should be reviewed in conjunction with the base contract documents to understand the complete scope of work, pricing adjustments, schedule impacts, and any changes to contractor obligations or project specifications. Contractors and interested parties should ensure compliance with all addendum provisions in addition to the original contract requirements.
