Posted by Sand Box John on Wed Mar 22 21:05:12 2017 Construction Passes 56 Percent During Very Mild WinterOld Man Winter has been especially kind to construction of Phase 2 of the Silver Line. Aerial construction at the entrance into Dulles Airport captures a dynamic view of the Dulles Terminal as the American flag blows in the wind. Photo by Jennifer Thomas Alcott, Capital Rail Constructors Bad weather never really stopped us, according to vice president and project executive director Charles Stark who recently said construction of the main system-the track, the stations, the support infrastructure etc. has topped the 56 percent mark and construction at the huge rail yard being built on Dulles Airport property is at 46 percent. According to a recent report on the status of construction prepared by John Kearney, the project's construction manager, plenty has been accomplished recently. For example, 223 deck spans have been poured. That's 76 percent of the total needed. All 183 of the needed pier caps have been poured. In March, the final aerial guideway girders at Dulles International Airport were set in place near Saarinen Circle. The four 84-inch tall precast concrete girders measure nearly 140 feet long, weigh approximately 95 tons each, and will support the Silver Line Metrorail trains that will run through the airport, says Jennifer Alcott, a spokeswoman for the construction contract. Kearney said crews continue to drill and set anchor bolts and bearings on the pier caps for girders on the aerial guideway columns, and continue to install girders at the entrance to Dulles Airport. Also, aerial deck spans continue to be poured just west of the airport station. Straddle bents have been set over the eastbound lanes of the Dulles Greenway.  Cast-in-place concrete activities are ongoing at the Herndon Station south pavilion site. Photo by Jennifer Thomas Alcott, Capital Rail Constructors Soon crews will be installing pedestrian bridges at five stations to provide access to the stations. Drainage work and track wall construction continue. Protective slabs over Fairfax County's waterline near the Reston Station are being installed. Hand mining for utility tunnels demanded by high-density granite is wrapping up and communication lines are being relocated to make way for installation of the pedestrian bridges. Directional drilling continues beneath Horsepen Pond to provide for utility line installations.Track work continues all along the line at grade and in the air. Station foundation work continues at the Loudoun Gateway Station and at the Ashburn Station. At the Reston Town Center Station, precast erections and station wall work is underway. At Herndon Station, structural steel installation for the vault roof has begun along with precast detailing and grouting. Cast-in-place columns are being set, the pier for the pedestrian bridge is being built, and walls and decks are being installed at the South Pavilion.  Roof panels are welded in place at Innovation Center Station. Photo by Jennifer Thomas Alcott, Capital Rail Constructors  At Innovation Center Station, tabletop piers will support the pedestrian bridges that will provide access between the station and the south side of the rail line.

Watch for Lane Shifts in Tysons Corner Don't be surprised when you see some Dulles Rail Project construction crews working in Tysons. Crews are doing some maintenance and warranty work at several locations and there is some need for lane closings while this work is being done. In late March, curb realignments take place at three locations - on Tysons Boulevard and at two spots along Route 7. All three require lane closures. Also, rail project crews and VDOT representatives, along with a team of contractors and inspectors, will clean some storm drain pipes along Route 7, using a camera to video and inspect both storm drains and underdrains. Crews also will identify, measure and document deficiencies they may find. This work will require weekly nighttime lane closures. The first set of lane closures will be on westbound Route 7. The public will be notified in advance of this work. VDOT and MWAA will coordinate safety and weather-related impacts on the work. Motorists are likely to see Fairfax Police Department escorts working at intersections and multiple lane closures.

Wasn't it supposed to be open by now?When propose and before the NEPA studies were begun, projected opening for the entire 23 mile 11 station branch was 2016. WMATA had never built and opened a single segment of that length in the past. The longest segment WMATA open at one time was the 12 mile 18 station National Airport to Stadium - Armory segment on 07 01 1977. It was broken up into 2 segments for budget and cost reasons.

That's some serious coin!Cost per mile is peanuts compared to the SAS. But then it will never generate the boarding counts the SAS has generated so far.

Elevated lines have always been cheaper than tunnels in crowded urban areas. That was the explicit reason that so much of the Contract 1 and Contract 3 subway was built as elevated.All that being said, it's beyond unlikely that any signficant new lines in our area will be built as els. I'll consider us lucky if the SAS ever reaches Phases 3 and 4. Even Phase 2 is not a certainty. |

Plus DC accomplishes it by partially building at ground level in highway medians. NYC highways don't have medians. The best we could get is Airtrain-style construction. |

Plus DC accomplishes it by partially building at ground level in highway medians. NYC highways don't have medians. The best we could get is Airtrain-style construction.Prior to the build out of the Tysons, Dulles, Loudoun county Silver line branch, WMATA built only one segment in a highway median and that is the west end of the K Route Orange line. The majority of the rest of the surface segments run parallel to railroad right of ways. The east end of the segment in the highway median between the tunnel portal and the East Falls Church station is in a former railroad right of way. John in the sand box of Maryland's eastern shore. |
