A quick wander up the line by John, our structures engineer, has found the following situation at lunchtime today:

Bridge 5, Little Buckland



After filling in with concrete on Monday, the Cheltenham end abutment shuttering to the 2nd lift of concrete has been removed and the space behind has been partly back filled:





At the Broadway end the first concrete pour behind the wing wall and to the stepped foundation under the north west wing wall was completed. Setting out for the sloping second stage shuttering, to form the sloping wing wall concrete backing, was just being started:

Low level of the down side

The contractor hopes to achieve a further concrete pour on both ends next Monday (subject to concrete arriving, as promised!). It is very difficult to get materials at the drop of a hat at the moment, there is such a boom in the construction industry.

Bridge 3, Pry Lane


Brickwork pointing to both ends of the Broadway end abutment wall has been completed, and a few chipped bricks replaced on the downside end of the arch.

Bridge 1, Broadway

The steelwork repairs are progressing well, with work alternating between working above deck on dry days and below deck during wet periods. A lot of heavy hammering could be heard throughout the day today. The badly distorted rail bearer repair is virtually completed (before & after photos below), as is that to a lesser affected one.

Perimeter repairs in progress
With dry weather today, efforts were being concentrated on fully welding around the perimeters of the plates tacked into place last week.

 More updates as soon as we have something to report. It all seems to be going very well, thank you for supporting us !

  1. What's left to pour at the south end, which looks fairly complete? I see some rebar sticking out the top, so given that I assume they are going to pour a tiny bit more on top?

    Also, were engineering drawing prepared for this repair, or was it more the contractor looking at the situation and saying 'Oi, that needs a lot of concrete behind it.' Not castigating if so. just curious.

    Thanks again for the updates - most interesting!

  2. Hi Noel,

    There is about 1M of concrete to go on the south end, which will bring it up to the underside of the steelwork.
    A lot of preliminary detailed inspection work was done and our Engineers - Halcrow carried out design checks and prepared 42 detailed drawings. Then detailed specifications and tender documents were prepared and from these a contractor was appointed. It has been fast and furious ever since as we had to close 2 roads, which always causes issues!!

    Thanks for your interest.

    1. Thanks very much for the reply!

      I would assume there have also been adjustments to the course as they got into the work (once things are removed/dug out, one always finds things one didn't know about)...
