Project Status and Schedule:

Monthly Project Update - May 2014

The Interim Operations Site for bus traffic and passenger waiting areas continues to function successfully, as it has since the start of operations in September 2008.

The Transit Center portion of this project is nearly complete except for the necessary concrete remediation work. The decks for Level 330 and Level 350 and the two pour strips on the 330 level are deficient and require remediation. In July 2012 the County hired an independent consultant KCE Structural Engineers (KCE) to evaluate the structure. KCE issued its report on the non-compliant work on March 19, 2013. A further report was also prepared for the County Executive by a pro bono Independent Advisory Committee and issued on April 21, 2014. The remediation at the SSTC is based on the joint recommendations of both reports. The County, WMATA, Contractors and Consultants continue to collaborate on the proposed design options to repair the deficiencies.

Phase One of the remediation of the transit center has been completed. The work included repairs to the two pour strip top slabs and the construction of nine (9) concrete support beams under each pour strip. The pour strips are located on the far east and west sides of the transit center at the 330 (middle) level.

Phase Two of the remediation will provide for a 2 inch overlay of latex modified concrete (LMC) installed over the existing concrete road surfaces on the middle and upper levels of the transit center. The LMC design was approved by the County’s Department of Permitting Services on October 11, 2013. Preparatory work has been ongoing and is now mostly completed to accept the LMC. In addition to the LMC overlay, the remediation work in Phase II will include additional reinforcement of the existing beams and girders in the superstructure of the SSTC in order to eliminate the need for any future repairs which might result from shear and torsion forces on the framed structure. This additional reinforcement, or stiffening, results from the recommendations to the County from both KCE and the Independent Advisory Committee.

Activities for the remaining project work continue. These activities include installation of the Electronic Vehicle Identification and Display System, the Data Transmission System, final Commissioning & Closeout, and completion of items from the County’s work list with the Contractor. At the County’s direction the Interim Maintenance Program for the facility’s electrical and mechanical equipment will continue until the facility is turned over to WMATA.

The Metropolitan Branch Trail from the Silver Spring Metro Station Plaza to Ripley Street was opened to the public in January 2013. The Ripley Street sidewalk from Bonifant Street to the Metropolitan Branch Trail and MARC platform opened in February 2014. The public continues to have full pedestrian access on all sides of the facility.

The proposed Paul S. Sarbanes Silver Spring Transit Center is a three-tiered, urban, multi-modal, state of the art transit facility proposed for downtown Silver Spring.

It will feature;

  • 32 bus bays for WMATA Metrobus, Montgomery County Ride-On, MTA regional commuter bus, Van-Go shuttle, Inter-city Buses, and University of Maryland Shuttle,
  • Direct access to Metrorail and MARC,
  • 54 Kiss & Ride spaces and taxi spaces,
  • Intelligent Transportation system,
  • Multi-modal transit store,
  • Accommodation for future Bi-County Transitway, connections to regional hiker/biker trails and a local trail, and open space replacement and enhancement.

The new facility will replace and significantly increase the capacity, safety and efficiency of a more than thirty year old, aging, surface transit facility in the heart of the newly revitalized downtown Silver Spring, eliminate the existing traffic conflicts, increase pedestrian safety, facilitate multi-modal transfers and provide well-developed bicycle access into the mass transit site.

Planning for this facility has carefully addressed and considered future extensions of mass transit such as the Bi-County Transitway and the District of Columbia/Georgia Avenue Corridor facility as well as the planned regional Metropolitan Branch and Capital Crescent Trails and the Silver Spring Green Trail.

The new Paul S. Sarbanes Silver Spring Transit Center is designed for integrated private transit oriented development. The private transit oriented development, which will be paid for with private funds, is a mixed use project comprised of two residential towers with 450 apartments and condominiums and a 200 room hotel. The private transit oriented development will generate over 4200 additional daily bus and rail trips for a 7% increase in baseline transit ridership at the Transit Center.

The project is being funded through from the Federal Transit Administration (53%), Maryland Mass Transit Administration (11%) and Montgomery County (36%).

Structural Evaluation of Superstructure
March 15, 2013

The SSTC is a cast‐in‐place (CIP), post‐tensioned reinforced concrete structure with two elevated structural levels and an at‐grade level. The facility is located at 8400 Colesville Road, Silver Spring, Maryland.

During construction, circa 2010, concerns were raised about the thickness of the elevated slabs and positioning of the post‐tensioning tendons.

In 2012, Montgomery County retained KCE, who in turn retained Wiss, Janney, Elstner Associates, Inc. (WJE), Walter P Moore and Associates, Inc. (WPM) and others to assess, as a team, the as‐designed and as‐built structure. The purpose of this report is to summarize KCE's evaluations.

We recommend you download the pdf files to your computer and open with a current version of a .pdf reader. These files are large and may take some time to download.

Transit Services During Construction:

SSTCLook for special signs throughout the Interim Operations Site along Wayne, Dixon, and Bonifant that have a map showing the locations of your specific bus stop. You will also see new bus stop signs, shelters, and other amenities to accommodate the new stops. Access to the MARC station has also changed. Again, look for the signs directing you to the new walkway.

Final concrete work on the last deep storm drain manhole (MH 10) will finish during the next several weeks. That will be a big relief!!! It’s sad that the public will not see and appreciate the vast network of subterranean pipes and chambers holding water on site. Managing stormwater reduces flooding and the expense of building storm drain infrastructure downstream.
