DCMP 01 15 2011

All of the span beams at the junction flyover east of the West Falls Church station have been set. Roughly 4/5 of the concrete deck for inbound track N1 has been poured, roughly 3/4 on outbound track N2 Of the four stations in the Tysons Corner area Tyson East (Westgate) is furthest along.

The contractor was pouring concrete for the invert slab on the north end of the Falls Church yard lead cut and cover tunnel in the median of Dulles Connector Road VA-267. Looks like they are going to build this segment of the tunnel then shift the eastbound lanes of Connector Road and excavate and build the rest of the tunnel.

There is a hell of a lot going on along most of the length of the project area. The entire length of the route on the surface in the median of the Dulles Access and Connector Roads will be behind a concrete barrier wall similar to a jersey wall. Only differences is the wall is taller and will have acoustical barriers on top of it along selected segments. The barrier wall will be significantly more robust then the barrier wall that protects the K Route Orange line in the median of VA I-66 west of the Capital Beltway.

The invert slab under the east ancillary area at the Tysons Central 7 (Greensboro) has been poured. Most of piles that will support the invert slab under station platform have been driven. The invert slab under the traction power substation and west ancillary area has been poured. Several columns are starting to come out of ground west of the station.

Some of the column foundation have been poured at either end of the Tysons West (Spring Hill Road) station.

Several column are at various stages of completion for the flyover from Leesburg Pike VA-7 to the median of the Dulles Access Road.

With the exception of the activity in the Leesburg Pike VA-7 Dulles Access Road / Dulles Toll Road VA-267 interchange most the activity along the Dulles Access Road begins about 1/2 mile west of Trap Road.

Of the five station in Phase I Wiehle Avenue is the one that is furthest along. Station platform slab poured. Virtually all of the mezzanine structural steel has been set.

I found out that most of the structural steel on the project is coming from a vendor that is based in Delmar Delaware, said vendors shop is less then 15 minutes from where I live in Hebron Maryland.

Lifting gantry #3, the white one, working over the Capital Beltway VA I-495, has been assembled on the inbound track N1 columns east of the Capital Beltway VA I-495 more then a month ago. However no segment have been lifted into place. I have no idea why they have not started assembling the span.

This gantry is different then the other two as it does not have the capability to move laterally after completing the assembly of a span. The gantry will be used to assemble spans that have segment that will be fixed to the columns, no expansion joints on columns. All other post-tension spans have expansion joints at the columns.

Lifting gantry truss #2 started east of West Park drive and worked east towards the Capital Beltway. When it reached the staggered columns on the west side of Capital Beltway VA I-495 it stopped and crawled west and began working west to Tysons Boulevard.
