Edmonton's South LRT Extension

Tangent Pile Sequence

This page will have photos taken looking towards the tangent pile, the place where the TBM will start tunnelling from. These photos were possible because of a "bay window" created by the site fencing going around a bus bench at a future bus stop.
Take a look at the grass next to the fence in the photos as it goes from pretty much nothing, grows, dies and is now starting to grow again.

April 16, 2003
Continuing excavation.
May 3, 2003
More horizontal I beams in place.
May 15, 2003
Diagonal beams have been attached to the horizontal I-beams. The red circle drawn on the face of the wall is the approximate outlines of the tunnel.

May 20, 2003
Excavation continues, as does work on the face of the wall to remove piles where the mole will begin its tunnelling.
May 23, 2003
A photo taken a few days later showing the outline of the tunnel and where some of the concrete has been removed.
May 29, 2003
Excavation is being worked on for the placement of the I beams that will help provide support for the TBM in this area.

June 4, 2003
The I beams have been lowered to the base of the tunnel portal, and are being worked on before having concrete poured around them to form the TBM launch pad, which occurred the next day.
June 9, 2003
Concrete has been poured around the I beams. This is probably to help with the TBM. Some parts of the TBM have been lowered into the tunnel work site.
June 12, 2003
The base for the TBM is now in place.

June 14, 2003
Work has started on assembling the TBM.
June 17, 2003
The first part of the TBM is almost complete, just missing one section.
June 17, 2003
The first part of the TBM looks complete now, though I am sure there was still lots of work to do on it.

June 23, 2003
The second part of the TBM is nearing completion.
June/ July 2003
Work on assembling the backup train has started
July 2003
Continued work on backup train.

July 2003
Not much different than the next photo.
July 9, 2003
The backup train is starting to take shape.
August 10, 2003
The TBM and SLRT site resting at night.

August 24, 2003
The TBM's trip north has begun.
August 26, 2003
1 day before the TBM got fully underway.
September 30, 2003
Not from the usual spot for pics for this series, but a shot of the same general area at night.

October 13, 2003
TBM train sitting ready for the next days work on a weekend.
October 22, 2003
Train loaded with spoil emerging from the tunnel.
October 29, 2003
A 2 car train emerging from the tunnel

November 27, 2003
Backup train being returned to the start of the tunnel.
November 30, 2003
Work underway to get the TBM reassembled for the northbound tunnel.
December 18, 2003
Reassembly work on the TBM backup train.

December 18, 2003
Continued work on the TBM for northbound tunnel.
The southbound tunnel has been covered by a white tarp.
January 14, 2004
TBM underway on the job of tunnelling the northbound tunnel.
April 26, 2004
The tunnelling is done! The TBM and all related components are pretty much gone from the portal site.

THIS SPOT LEFT INTENTIONALLY BLANK FOR FUTURE PHOTO FROM MID-MAY.
May 20, 2004
Work on cut and cover section, installing forms for the lower part of the west side wall for the northbound tunnel. The low part has been poured for the east side of the southbound tunnel.
