Call 003 Z99CN03

The solicitation Z99CN03, titled "Call 003 Z99CN03," issued by the Massachusetts Bay Transportation Authority (MBTA), seeks bids for the replacement of fire alarm and suppression systems at the Charlestown Building 6 Bus Garage located at 21 Arlington Ave, Boston, MA 02129. The project, with an estimated value of $10.5 million, requires the installation of fire detection and alarm equipment from approved manufacturers—Notifier, Gamewell/FCI, or EST—along with a Remote Graphic Annunciator at the firefighter entry point. The new fire suppression system must be fully installed, tested, and operational before any demolition of existing systems can occur, with work executed in phases to maintain operational egress routes and keep adjoining spaces functional throughout the duration of the project. Specific attention is directed to phasing requirements outlined in Contract Drawings T003 and T004, with the mezzanine level allowing for a single phase where all ceiling tiles may be removed simultaneously. Painting of fire alarm conduits must comply with Specification 16195 Section 2.5, and the lump sum line-item 0751.111 covers all related painting work under Sections 13850, 16195, and 09900, referencing detailed construction specifications and appendices. The contract is subject to Buy America requirements as specified in Instructions to Bidders Section 1.25, mandating domestic sourcing of materials and components. Bids must be submitted electronically via www.bidx.com no later than 2:00 p.m. on May 28, 2026, with bidders required to incorporate all changes from issued addenda—whether additions, omissions, or substitutions—into their submissions and correctly reflect the addendum number on the bid form. Final acceptance of all fire protection systems must adhere to General Conditions outlined in Specification 00700, and testing protocols must follow Standards 15500-310 and 3.11. The procurement is classified under NAICS Code 519290 and is categorized as a SLED (State, Local, Educational) procurement. The full scope of work depends on the Construction Specifications, Contract Drawings, Appendices, and the Response to Bidders Questions, all of which are integral to proper proposal development.
