Stanton - 160 days and counting

Thursday 22 August

It's 160 days since we started on Culvert 11A, that's calendar days, which equates to 68 working days. The original plan was for 18 weeks, we are now at 22, but given the changes to the plan with things like the rebuild of the north wall on the up side we are not that far out. Some other rail infrastructure projects would love to be showing only 4 weeks slippage 😉

What did we do today, built more walls and did more concreting. With 5 in today, there was no shortage of skilled labour. It allowed us to do some more vegetation management on top of the other works.

There was a visit to Toddington Station this morning to look down the gully drains, there's a bit of an over-spill issue that is endangering the shop and ticket office during heavy rainfall. The water lashes down the approach road and fails to take the corner ending up on Platform 1. This is a Construction  & Maintenance team task, but as it impacts drains we can bring in some of our kit to trace pipe runs and generally help out.

Back at Stanton, Michael was carrying on with the build of the cess outfall walls on the down side,  ably supported by Alastair, Nigel and Andrew ferrying supplies.

Which wall should I start on 

The concreting done on Monday has set, so the shuttering was removed from the down side cess and a second layer applied to the up side scour protection.

Stuart went off in search of the down side of Culvert 11B, this area needs to be cleared as the Phase 2 of the project includes installing pipe to clear up a wet patch at the toe of the embankment.

Back at the bridge, Nigel and Andrew were stocking up the bricks for the down side cess headwall

Not quite enough on the first delivery

  1. very interesting blog - lovely brickwork!
    now there is a wall in front of the gabions at 11A downside, is there a drainage path for water which seeps through the gabions?

    1. Hi Andrew, there are weep holes in the walls in front of the wing walls. As the gabions have a flat concrete base the water will escape out the end into the ditch. There's a void behind the wall for this

  2. It is all most impressive work, a big credit to everyone involved. I can see that the Drain Gang are doing remedial work that has probably been neglected since the 1950's. A long time ago.
