The final stage of work on the Silver Spring Transit Center won’t be able to begin until late March or early April, leaving officials unable to schedule an opening date for the long-delayed project.
Permits allowing for the preparation and placement of the latex-modified concrete needed to ensure the proper strength and thickness in parts of the facility were obtained last week, and work on fixing cracks in the concrete will take place through November, according to a memorandum sent Tuesday from Department of General Services Director David Dise to County Executive Isiah Leggett (D).
But workers won’t be able to put the concrete mixture down until temperatures are consistently at or above 40 degrees, meaning probably not until late March or early April, the memo said.
“The earlier we get in, the better,” Dise said Tuesday.
The overlay is expected to take six weeks once work begins.
All other work on the project is scheduled to be finished before the overlay is done.
Once the overlay is done, the Washington Metro Area Transit Authority, the county’s partner in the process, will still need to do an inspection of the site, which could take up to 30 days, Dise said.
The uncertainty over the weather has left the county unable to determine when the $120 million facility at the corner of Colesville Road and Wayne Avenue in downtown Silver Spring will open, he said.
The center was originally slated to open in 2011.
Several other aspects of the project have been finished or are expected to be done soon.
Remediation work on concrete pour strips is complete, according to the memo, while a process to detect leaks have been developed and tests should be conducted in mid-November.
A March analysis raised concerns about some interior beams and girders, and a decision should be made in the next few weeks on whether they need to be replaced, Dise said.
