The design services scope of work consists of preparing construction bid documents for the removal and replacement of deteriorated direct fixation fasteners (DFFs), worn rail segments, and damaged Type TM floating slab panels within a specific section of the NFTA-Metro Rail tunnel system. This project is part of NFTA’s multi-phase rail infrastructure modernization program and is funded in part by the Federal Transit Administration (FTA). The selected Consultant will be responsible for developing a detailed Design Rationale Report (DRR), plans, specifications, cost estimates, and construction sequencing strategies tailored to tunnel access constraints and operational requirements. All design elements shall be compliant with applicable standards. The project will be delivered using a design–bid–build methodology, with design services concluding at contract award for construction.
