Work has commenced on the excavation of the tunnels that will hold the conduits that will carry third rail power from the substation to the right of way east of Dulles Airport. Work continues on the installation of the 34.5 KV power feed bus.

Grading work continues from roughly Centreville Road to the location of the east abutment north of Autopilot Drive.

The foundations for the Innovation Center station are mostly done. A tower crane has been erected at what looks like mid platform in the track bed of track N2, north side, of the station.

The east abutment north of Autopilot Drive is well underway.

Excavation for the Dulles Airport station mezzanine has begun. The lanes of Saarinen Circle have been shifted to accommodate the excavation.

There were reports of cracks in the precast girders shortly after they were set on the columns along Air Fright Lane in April. No reports have been made as what will be done with those girders. It seem the cracking issues has been addressed as the Track N2 girders were set on the columns north of the Hertz Rent-a-car entrance on Autopilot Drive.

All but a couple of the mainline columns from southern most column along Airfright Lane to the shoulder of the Dulles Greenway are done. Most of the columns for the east yard lead are done and all of the west yard lead column are done from the junction of the yard leads to the shoulder of the Dulles Greenway. The column for the straddle bents that will support both the mainline and the west yard lead have been built. Work on the column piles in the median of Dulles Greenway has not begun yet.

Test track and Commissioning Facility

The commissioning facility building has been turned over to WMATA and is now being used by the folks charge with making the 7k cars revenue ready.

The multilevel parking structure has also been turned over to WMATA and is being used by employees.

The test track ballast has been groomed to its finished elevation. Third rail section have been installed but have not been bolted and bonded. The track circuits Wee-Z bonds and marker coils to control automatic station stops have been installed.

Preparation work has begun on the abutments for the bridge over Centreville Road.

Grading work has begun in the area of the Innovation station and extends to the east elevated abutment north of Aviation Drive.

The Steel for bridge over Horsepen Run was installed on 04 10 2015.

The first segments of the right of way barriers, westbound side, has been installed east of the Rudder Road overpass over the Dulles Access Road.

Work continues on the installation of the 34.5 KV power feed bus that runs the full length of the route. Most is happening between the Herndon and Innovation stations. I will also noticed they are also installing the feed from the Virginia Power Dulles Airport substation along VA-28 Sulley Road between the Toll Road and Frying Pan Road.

Staging has begun for the construction of the columns west of the Dulles Airport station.

The first precast girders for the elevated were set on the columns along Air Fright Lane on 04 21 2015. Two spans have been set.

The Column in the median of Autopilot Drive north of Rudder Road has been installed. The column cap has been partly completed.

All of the columns north to the east Dulles Yard lead junction are done. Two straddle bents columns that will support the mainline elevated over the eastbound Dulles Greenway off the shoulder have been installed.

The columns for both the east and west Dulles Yard leads are in various stages of completion.

Preparation for the relocation of the eastbound Dulles Greenway to accommodate the west Dulles Yard lead junction in the median is underway. The shoulder pavement has been milled off and grading is being done.

Nothing is being done along the Dulles Greenway west of VA-606 Old Ox Road. The preparation for the bridge over Broad Run remain unchanged.

Test track and Commissioning Facility

Track has been laid along the entire length of the right of way with the exception of the area in the vicinity of the contractor access south of Greenbelt Road.

Third rail segments have been delivered and are staged at various locations along the right of way.

I am assuming the crossover that access the test track along with the signal bases have been installed as those parts are no longer in the staging area in the south Kiss and Ride lot at the Greenbelt station.
