Start of another culvert for road 2 on the Gaul Road March Site.
You would not believe the amount of soil being dug out, we are 3 metres deep against the road edge. By the way if you are carrying out this kind of work it would be wise to employ a structural engineer.
After the inspection of the dig he will issue a “permit to work”
First photo shows Alan excavating another 750mm below the slab level. This will make a total depth from road level to 3.750m.
Saturday 13th February 2016 shutter is being put up, at the same time the steel fixing can be completed.

New contract started 9th December 2015:
3 vehicle accesses on to a new housing estate. Because vehicles have to cross a dyke there needs to have a culvert built, this is 2 head walls either side of the new access, built with concrete and reinforcement bars.
Day 1 after Highway approval, (as this is part of a S278) set up site as the norm
Day 2 As we are in a dyke, we have a water problem, best solution is when excavating, use the material to dam up the dyke. Pump the rest out.
Day 3 Road Entrance 1, Base of the first Head wall 6m x 3m (it is 2.4m below road level) knock some pegs in the soil base and concrete with lean mix, concrete about 50mm thick. This will be for the steel fixers to work on.
Day 4 Put together the steel bars, using plan and bar schedule. Fairly easy to read, example H16/02/39/3760 this is 16mm bar / 02 on plan / 39 bar / 3.760 lengths. Read with plan.
End of week 1

Day 6 complete steel fixing & get checked off by site manager & Highways
Day 7 Pour concrete
Day 8, 9, & 10 put together the steel for the other side & excavate base
