Committee signs off on ~$6.9M Central Subway design amendment and asks for post-completion review
Summary
The committee approved an amendment increasing the Central Subway engineering/design contract to address unexpected underground conditions, and members asked the MTA and federal oversight bodies to compile post-construction lessons learned for future projects.
The Budget and Finance Committee on July 15 approved a contract amendment to the Central Subway design and engineering agreement to secure specialized engineering support as the project approaches completion.
Tom McGuire of the Municipal Transportation Agency told the committee construction on the three underground stations is about 95% complete and that the amendment will provide additional funding for specialized engineers to address unanticipated site conditions encountered during deep tunneling. The BLA summarized the recommended increase of roughly $6.9 million and provided context by restating the project’s overall budget (~$1.6 billion).
Supervisors pressed MTA to conduct a formal post-completion review and identify lessons learned on technical, financial and community-communication fronts; MTA and the Federal Transit Administration’s project management oversight work were described as part of that review process.
Why it matters: the Central Subway is a high‑cost capital project with multi-year impacts on transit service and neighborhood construction; oversight and lessons learned are critical to avoid repeating cost and schedule impacts on future major transit investments.
Quote: "And that review gets at both the technical engineering issues...and project management," Tom McGuire said when describing the planned post-construction review.
Provenance: presentation began at SEG 831; committee vote recorded at SEG 988.
