Metro board members flagged several concerns with the Silver Line extension that could delay its expected opening date in July 2020.
At a Thursday board meeting, the board heard a comprehensive report about critical issues on the stations including cracked concrete an unleveled track.
In some areas, track plates are curved, creating a gap between the plate and tie of track plates. The report also found irregular track cross-levels. The contractor attempted to install pads, create custom guard rail plates and install hardware for all turnouts — a fix that Metro rejected because it is “not a safe and effective longterm solution.”
The report also indicated that the ballast — the gravel around the tracks — was contaminated with materials that could cause drainage issues and pose a potential safety risk.
Metro also rejected the contractor’s application of a sealer to remedy cracked concrete at five at-grade stations. The fix was implemented after a federal investigation confirmed the contractor falsified test results at the concrete plant.
The body is seeking a safe and effective long term solution after tests showed that the sealer did not effectively penetrate cracked concrete in 20 percent of the 25 areas Metro’s Office of Inspector General tested.
According to WAMU, Maryland board representative Michael Goldman said the findings cast a “dark and foreboding cloud” over the expected opening date provided by the Metropolitan Washington Airports Authority.
The Metropolitan Washington Airports Authority must address concerns highlighted by the report in order for Metro to take over the project.
