Greetings First Street Tunnel Stakeholders,

        

Below are FST community updates covering the remainder of December and early January.

Upcoming Holiday Construction Schedule:  Construction will continue until Thursday, December 24, but will stop in the early afternoon.  Construction will resume on Monday, December 28, 2015.  Construction will continue through Thursday, December 31, but will stop in the early afternoon.  Construction will resume on Monday, January 4, 2016.  Each upcoming holiday weekend will be free of First Street Tunnel construction activities.

Lucy, our tunnel boring machine, is continuing to make her way southbound under First Street.  She is currently at the end of the 2000 block of First Street, and will be approaching the 1900 block as early as Monday.  We are pleased to report that Lucy has made a successful run under the 2400, 2300, 2200, 2100, and 2000 blocks.  We placed door hangers on the 1900 block of First Street on December 10 up to Rhode Island Avenue.  We anticipate Lucy completing her run by the end of December.

Construction Activities at V Street:  Concrete deliveries will continue.  Trucks will be entering all three sides of the VS-CSA.  The contractor will use the north and south sides of First Street for concrete pours associated with the two diversion chambers near First Street.  The V Street entrance/exit is being used for soil excavation haul-out from the third diversion chamber located adjacent to the DC Water project site office at 2036 First Street.   Reminder:  Once the contractor starts a concrete pour, it has to be continuous until completed; at times, then, we may go beyond the scheduled work hours. 

Construction Activities at Adams Street and Flagler Place:  The contractor has completed the first 80 feet of the 300-foot-long adit tunnel.  The remaining 220 feet of adit tunneling will be constructed using a “micro” tunnel boring machine (MTBM).  As you may recall, the MTBM will interface with the new First Street Tunnel under the corner of First and Adams Street.  In addition to ongoing adit construction, there are additional concrete pours scheduled from Flagler Place in order to complete the diversion chamber within this site.  We completed the adit excavation and are starting the concrete liner.  There remains a section for the adit that requires a different construction method.  Around the middle of January, SKJD will be bringing in support gear for the MTBM assembly, with some equipment that is approximately 16 feet tall.  Therefore, residents should expect the interior of the construction staging area to change for the mining of the remainder of the adit.

Construction Activities at Thomas Street:  At the pump station, DC Water is currently installing a 16-inch force main across First Street from Thomas Street to the alley behind the Mt. Bethel Baptist Church.  Traffic is restricted to one lane with flaggers. This construction should be completed by the end of December.  As Lucy proceeds under First Street, SKJD may have a crane operator and some limited surface activity at the Thomas Street construction staging area monitoring Lucy’s progress. At this time, we expect Lucy to be in this area around December 18.

Next Tunnel Forum Meeting:  The next Tunnel Forum meeting is scheduled for Thursday, January 28, 2016 at 7 pm.  The meeting location will be St. George’s Episcopal Church at 160 U Street NW.  Hope to see you there!
