Capital Rail Constructors continues maintaining their steady pace.

Right of way barriers along the Dulles Access Road at various location have security fence posts on them, in some places the chain link fabric and barbed has also been installed. There are still a few gaps that have been left uncompleted to allow equipment and material access for station construction. Most of the sections that have completed barrier walls have the grading done to the point for the grading of the track sub roadbed, surface cable tray trenchs have been or are being installed along some of those sections.

Ground work is mostly complete at the traction power substations east of the airport. Most of the ones west of the airport are at the ground work stage. Traction power substation #15 on the south side of the Dulles Access Toll Road inside the loop ramp from southbound Sulley Road has its prefabricated switching equipment inclosure in place. All that remains to be done is to set the precast concrete walls and pave the access driveway.

Reston Town Center has it west ancillary area totally inclosed. All of the column to support the mezzanine are done. The invert under the platform is in place. No work has been done on the site of the south entrance pavilion.

Herndon has its mezzanine slabs set along with the station managers kiosk. The west ancillary is also in place. All of the column for the south entrance pedestrian bridges are a various stages of completion. The south entrance pavilion has begun to come up out of the ground. No work has begun for the north entrance. Grading is being done on the site short term parking area along with also being used as a staging area for drainage pipe and precast manholes. No work has begun on the site on the second garage west of the existing garage.

Innovation Center as mentioned back in October is is structurally complete. All but one of the south entrance pedestrian bridge column are complete. The south entrance pavilion is ready for the installation of the precast enclosure walls. No groundwork has begun beyond site clearing at the site of the north entrance.

The rail that was staged at east abutment in the median of the Dulles Access Road west of Rudder Road has been welded into longer lengths. The stacked welded rail extends from just east of the abutment to the bridge over Horsepen Run. Most of the rail staged in the lot on the southwest corner of Autopilot Drive and Rudder Road is gone. I think we can safely assume it has been lifted up onto the elevated along Autopilot Drive and welded into longer lengths. There are multiple concrete samples on the ground at the north end of Autopilot Drive that I assume are samples from the pours for the track fasteners grout pads. Angle iron for elevated guard rail has begun to be staged adjcent to the rail that remains.

All of the columns on the airport property to support the elevated are done. Girders have been set from the 4th straddle bent over the westbound Dulles Access Road south of Aviation Drive to east end of the airport station. All of the cross girders that will support the platform girders have been set. Three spans of track bed girders have been set at the west of the station and continue to the where the girders were set along Air Freight Lane. Two platform spans have been done and have their precast slabs in place. The west platform ancillary has also been set. Deck slab pouring is moving east following the setting of the girders.

At the west abutments in the median of the Dulles Greenway, the west yard lead girders have been set to the abutment. All of the columns are done for the mainline east of the abutment. The 6th (west) straddle bent has its forms in place and the concrete has been poured the 5th (east) straddle bent is waiting for the forms to be stripped from the 6th.

Grading has begun in the median of the Dulles Greenway in preparation for drainage and the barrier walls.

Erection of the steel frame for the shop building has begun. Excavation and instalation of the third rail conduits in Dulles Yard is at verious stages of completion along with continuing project of removing bed rock in the area of the storage tracks.

Loudoun Gateway has begun to come up out of the ground. The columns that will support the mezzanine level of the west ancillary are mostly done. Just under half of the barrier walls along the length of the station are done. The remainder range from not having their foundations excavated to waiting for the forms to be stripped. The Loudoun Gateway station is unique in that no piles were needed to be driven as bed rock had to be removed from the site to bring it down to the correct grade.

Grading has begun at both ends of the new bridge over Horsepin Run that is part of the Old Ox Road widening project.

It is difficult to see what's going on at Ashburn but I think we can safely assume groundwork is being done in perpetration for the column and barrier foundations.
