Steel delivery & the last big pour (of concrete)

Three, maybe four concrete truck arrive on Friday afternoon to fill in the top half of the back retaining wall, the hot tub slab and the footing for the wall to Ramoth.

Pre the concrete pour, post the last photos, the steel for the hot tub slab had been raised to increase the cover:

and the footing for the boundary wall extended:

The steel beams for the frame (some spans are too big for Glulam beams that wouldn’t become very thick) arrive:

On Friday afternoon the long concrete pump:

was extending up to the upper retaining wall:

2013-10-18 14.37.04_600w

That by Saturday morning, was set solid enough to walk on:

You can also see the boundary wall footing on the right the hot tub slab:

More groundworks progress

The footing to put back a wall between Silver Spray and next door is dug.

The drainage sheet for the upper section of retaining wall concrete pour is in place.

The over sized (to future proof) hot tub area slab hole is dug out and re-enforced. The boundary wall behind this has also been taken down to be replaced with a wall with a proper footing.

eco-fab factory visit

A visit to the ecofab factory in Bodmin reveals stacks and stacks of numbered panels. They house will hopefully go together in the planned order, so they are made in the order that they can come out of the factory and go to site.

In the above photo you can see a compressed cube of sheep wool that is put inside all of the boxes. There are bundles of this in the corner:

2013-10-15 16.38.23_600w

 

a few bits of which made it to my car (with permission):

2013-10-15 17.47.09_600w

 

It’s a “waste” product from sheep leather for high end cars (Bentley cars included, apparently), so it depends on what the wool was for as to whether it is white, another natural colour or dyed. Apparently a chunk of the wool bundles come from “Eastern Counties” (name of the firm I think).

2013-10-15 16.41.46_600w

 

The above floor / roof panel has horizontal bracing.

Wall panels have tick vertical boards and mesh across to prevent it all falling and bulking to the bottom.

The panels have different materials, such as bit-rock (for under the building to prevent rodent attack), the OSB 3 board (the main wooden sheets), cement board or 18mm structural ply.

The panel below is box 201, which will be the SE corner of the lounge at the south of the building.

Some shuttering comes down

Shuttering on the lower section, where the retaining wall is at full height, has come down. Leaving a wood board imprint on the concrete:

The pick on the digger has broken apart the rest of the wall and footing for the wall to the Ramoth courtyard.

2013-10-15 08.48.29_600w

By lunch time it was all taken away from the site:

The retaining wall looks solid:

Retaining wall concrete, wall smashing, small wall foundation

A lot went on today.

The big pile of earth and rock that was in the garage area, was cleared away in the morning.

The retaining wall and it’s foundation footing has been broken up a chunk.

3 truck loads of concrete have been pumped from the trucks to behind the retaining wall shuttering for the main house.

Three cement trucks arrive:

2013-10-14 14.47.20 - tweaked _600w

 

The truck parked in the garage area, just in from the cement lorry, is pumping the cement up the black pipe to the chaps pouring it in, and then vibrating it, so that it all settles down with no air gaps etc.

Looking at the area, that at the time of the photo hadn’t had concrete poured in, you can see the spacers to keep the steel bars a set distance in from what will be the external edges of the concrete.

You can see the picker on the digger, that is breaking apart the re-enforced wall and it’s foundation footing.

2013-10-14 15.07.30 _600w

At the front, a small footing is being made to re-instate the Kiephuis garden:

Kiephuis mains water pipe

When the old garage for Silver Spray was taken down and the site dug out for the new garage, this went into the neighbouring Kiephuis property.

– they OK’d this (the neighbours on both sites have been amazing).

The dig out exposed that they had an old, copper mains water pipe from the street stopcock. So before it was re-buried this was replaced with a modern plastic water pipe:

Silver Spray to Ramoth wall – Part 2

The under ground foot to the wall between Silver Spray and Ramoth is longer than hoped. So Graham and Sam are doing to jack hammer break it up, in order to take the wall down.

The wall just past the courtyard wall, southwards, has had footing and column of blocks put under it. The edge of the courtyard retaining wall has also been cut into, so that when it’s pulled down, the Ramoth rear section is left OK.

Footing:

Supporting block work column:

Silver Spray dug out trench to help the wall come down:

Ramoth side courtyard tiles come up to get down to the footing for the retaining wall:

2013-10-11-08.49.39_600w

By the end of Friday the wall was over, but still in one piece. A pecker bit for the digger will be on-site on Monday afternoon to break it up:

Silver Spray to Ramoth wall

Nigel and Sam have started taking down the “rotting” dividing wall between Silver Spray and Ramoth. The agreed plan is to put in a small footing and a 2 to 3 block wall up for now. Once the Silver Spray building works are done, we can decided if we want this wall to go higher in any areas.

This has exposed that the Ramoth courtyard, which used to hold back the rear garden with a retaining wall has a bulging lump of concrete into the Silver Spray plot. The bulge looks to be about a foot into the plot, which would narrow the path down the side of the house too much to leave in place.

Retaining Walls :: 1 step back but at least 3 forward

At least it was spotted. The black RIW double drain (black bumpy sheet with front white anti silt up sheet) that was wrapped around the garage wall was part buried before it was noticed that it was the wrong way around. It needed to be black thick plastic side to the garage wall.

Incorrect way around:

2013-09-24-09.06.23_600w

So Nigel and Sam spent 1 to 2 days digging a trench down to the bottom, in order to take it up and put it back in the correct way around.

2013-09-27-13.55.00_600w

2013-10-01-09.03.51_600w

And then repeat back filled, compacting every 20mm of in-fill.

2013-10-01-16.13.57_600w

Sam and Nigel (the only 2 on site for a bit over a week) dug under the wall of the neighbours (Kiephius) wall to expose their mains water feed from the street stop valve. This is so that we can replace it with a modern Polypropylene water pipe before it is re-buried.

2013-10-03-08.58.24_600w

They have also started building a small retaining wall, backfilled with concrete to better support the ground under Kiephuis balcony. Their property structures are going to end up better supported than they were.

2013-10-03-09.17.18_600w

 

The link wall between the front NW corner of the garage to the Kiephuis front wall has been built.

2013-10-07-15.19.11_600w

 

On Monday the 7th of October, the site team jumped from 2 (Nigel & Sam) to 6. The pace picks up and the current position of being behind schedule looks set to be redressed.

The main house retaining wall shuttering is coated to help it not stick to the cement before it’s put in place.

2013-10-07-15.30.01_600w

 

The steel work has a 2nd layer put inside it, with cross links.

When this first goes up the cover (distance between the steel and the outer edge of where the concrete will exist, so the distance within the concrete the steel will end up) of the steel looks to be a problem, but spacers are put in, to hold it at least 30mm in from the external earth, wood or chippings.

2013-10-08-16.23.48_600w

 

2013-10-08-16.23.55_600w

The shuttering going up, with the remaining steel mesh put up against the wall in the garage and the rest of the site cleared (note the back left (SE) ramp dug back) makes the site suddenly big again.

2013-10-08-16.24.52_600w

 

2013-10-08-16.24.41_600w

That’s a lot of material that has been heaped into the garage area.
