Maddomswood Barn Conversion

Week 10 – 21st – 25th September

Monday

We arrived this morning to find the trenches we had dug full of water. And it was still raining.

The concrete was due to arrive at 2pm so we finished the mesh to the oversite and I went to Jewsons to hire a pump so, when the weather improved as it was meant to in the afternoon, we could carry on with the drainage.

I had arranged for a Grab Lorry to arrive to take away the hard-core. The first price I had got from a firm was £250 per load. This is what I had based my budget on. I called around and eventually got a price of £150 + vat which was great.

During Monday he took away 3 loads with about 5 loads remaining. He was asked to return on Wednesday to give us space to carry on with the drainage.

At 2pm, no concrete lorry. Still nothing at 3pm. We had ordered 6+ which means a 6m3 load plus a further amount to be confirmed which would require the concrete lorry to return to the yard to collect the +.

This was about to be the worst concrete pour I have ever been involved in:

  • The lorry arrived at 3.30pm which was not going to allow time for a return so the concrete would need to be finished Tuesday morning.
  • It was raining and….
  • The lorry could not or would not drive around the back of the barn so the concrete could be delivered via the chute. Instead Dan had to use the digger bucket to move the concrete to the far end of the slab. This took 2 hours!!! 5.30pm finish.

Tuesday

On Tuesday morning I assessed how much the + was to be and called in saying “2.5m3 please”.

The concrete lorry arrived and this time we were able to use the chute for the remainder of the slab but again we needed to use the digger bucket to deliver the concrete to the stair well slab. All time consuming stuff.

OK…so here it is….the slab is now finished; as was the stair slab….but the concrete kept coming; Dan kept filling the bucket and dropping the concrete in the retaining wall trench which had been dug but we weren’t intending on filling yet. After 10 or so trips I asked the Concrete Lorry Driver “How many more buckets do you think”. He said “20 to 25”…..I said “how is that possible, I ordered 2.5m3”…he said “there is 3.5m3 on the ticket and I still have about 1.0 – 0.5m3 on the lorry”….whhhaaaat!

I called the office and he said it was a breakdown in communication and apologised. The lorry left with the m3 still on board.

So, in summary:

  • Order concrete for Mornings only so that if there is a delay you can still finish the slab or trench the same day.
  • Use a pump if the location for the concrete has access problems. A pump is messy but much quicker than using a digger bucket, especially in the rain.
  • Double check with the driver upon arrival that the quantity ordered is the quantity on the lorry.
  • Arrange for the sun to shine.

Wednesday

It is now Wednesday and I am trying to forget about the concrete debacle.

Dan is carrying on with the Drainage around the Barn. Leon starts the Block and Brickwork to the internal dwarf walls. Andy is helping both.

The brickwork takes a bit of time as the sole plate beam is bendy so if the wall had to be built to follow the beam. We also dropped in some large bits of stone that had been taken out or the original wall.

The grab lorry arrives and takes a load first thing. I ask him not to return until after 2pm so Danny can get the corner drainage chamber finished which is adjacent to where he drives in.

Dan finishes the corner drainage and backfills. The grab lorry arrives and drives down. He doesn’t hit the chamber but the weight pushes the earth down and the chamber tilts. It will have to be done again. Great!!

NOTE wait until the heavy Lorries have finished their work before installing drainage. We were behind due to the weather but pushing on, as we did, actually delayed us further.

Thursday

We arrive on site on Thursday and the scaffolders arrive to scaffold the Milking Parlour. They will return on Monday to erect the scaffold with the tin roof around and over the barn. We need to make sure all the drainage and any utilities works are completed by then with the ground fully compacted.

Friday

By Friday morning the drainage is finished and now Dan is starting work on the trench for the Gas, Water and Electric to be laid in from the A21 road to the barn.

He starts by gunning out the concrete and digging the Road crossing trench from the corner of the Barn, across the farm drive to the north side of the track. We use Fibre Glass Road plates across the trench whenever a car requires access. These were not the correct plates to use and they were damaged beyond repair very quickly.  NOTE – the fibreglass plates are for use over small holes and to protect pedestrians.  If you have a large trench over which vehicles will need to pass you will need to hire in the metal plates – these are heavy and are not easy to manoeuvre.

Once the depth of 850mm approx has been achieved (750mm cover once the pipes are laid) the pipes are placed in the bottom of the trench. They are then covered with shingle, then Gas Tape is laid over the gas pipe; after this we back fill with earth and then MOT type 1;  the whacker is used as the layers go on to ensure the trench is properly compacted.
