Well it looks like my last post was not the last before opening day of Phase I. If all goes as planed this one will be the last.
Most of what has been done sense I was last out there is touch up work inside and around the stations, pavement work, and error corrections. The touch up work included things such as the inclosing of the third rail cable trays, placing the final lift of asphalt in the Kiss and Ride lots at the McLean and Spring Hill stations. Connecting the down spouts at the entrance pavilions to the storm sewers and replacing parts of concrete apron around the Greensboro station north entrance pavilion.
For those not up to speed on what's delaying the opening, here is a summery.
There were several problems with some of the work done by various contractors that didn’t meet either contract specification or requirements of the building code. Public address speakers lacking required UL fire rating, leaking roofs, elevator and escalator reliability issues to name a few. In one case there was excessive leakage of hydraulic oil in the lift piston of one of the elevators.
There were issues with hardware that allows the monitoring and controlling of the various systems and subsystems from WMATA central control (supervisory control and data acquisition, remote terminal units). There also were some issues with a hand full of track circuits that were not reliably transmitting speed commands to the trains. None of these issues would have effected the safe operation trains, however they would have effected the on time performance of trains running on the branch.
The correction have been made and or are being made.
WMATA took possession of the project from MWAA and their contractors on Tuesday 05 27 2014. Under the contract WMATA has 90 days to do final testing, employee training and simulated revenue operation before opening the line. The end of the 90 days is Monday 08 25 2014. WMATA has not announced an opening date. WMATA by tradition opens new segment on Saturdays, expect the open to happen no later then Saturday 08 13 2014.
The developer building the Vita Apartments, Tysons Tower and the Hyatt Regency on Tysons One Place in front of Lord & Taylor and parking garage E have built a pedestrian bridge over Tysons Boulevard that connects to the south entrance pavilion of the Tysons Corner station. The pedestrian bridge by way of The Plaza between the Hyatt Regency and Lord & Taylor will provide a direct connection to level 2 of Tysons Corner Center.
Principle construction has not commenced on Phase II, however preparation work has begun such as removal of trees from the elevated easement along Autopilot Drive on the airport property, installation of a silt fence around the site of the station at Dulles Airport, placement of surveyor stakes at various location along the easement and soil core sample collection.
Test track and Commissioning Facility
The construction of the Commissioning Facility building in Greenbelt Yard looks to be complete. The structural work on the parking garage also appears to be complete. The contractor is sill doing the ground work along the test track right of way in preparation for the grading of the sub roadbed. Surface cable trays and stick rail were delivered to staging area adjacent to south Kiss and Ride lot at the Greenbelt station some time back in April or May. All of the stick rail has been welded up into roughly 600' lengths.McLean station
