    Foundation course

    The slab team from MBC arrived on site this morning. It's like having the building version of whirling dervishes who've just dropped a few speedballs. My word, they make progress! The team is headed up by Harry and he has 3 others in his team, but this will fluctuate a little over the course of the job with Harry needing to have a look at another job for most of tomorrow then the younger lad taking some leave to go to a music festival. Tsk, the youth of today! He worked like a machine, though, apart from the bit where he nearly rolled over one of the piles as he was looking in awed astonishment as a rather attractive young lady farmer drove past on the nearby track in a JCB that was most definitely bigger than the roller machine he was on. I don't think it was the vehicle that caught his attention so much as the driver. Sniggers all round. I arrived just after 8 am this morning and the first lot of hardcore had already been delivered. In total, there were 4 loads of type 1, but I piggybacked onto this and ordered an additional load (paid for by me) which the team will then spread and roller for me in the area beyond the bucket in the above photo, which will create a nice level area for the crane when it arrives to bring in the timber frame. I've had really good luck with the weather so far and hope it continues, but if it rains between now the completion of the timber frame, the site will turn to mud PDQ and slow things down horribly. Once the hardcore was going down and getting compacted, the piles were cut off to the correct height, leaving the rebar in position, ready to be tied into the beams. I have no idea what you call the digger thingy that they are using to move the stone around the site, but it's an impressive beast. It looks a lot like the bottom of a tank with its caterpillar tracks and then something a bit more transformers-like with its swivelly cab and arm. Either way, it was mechanical poetry in motion when driven by someone who clearly knew what they were doing. The team will have been working till 7pm this evening, so they will have got all the hardcore down and compacted and were going to start on the sand, if they had the time. The first load of sand arrived about 4.30 this afternoon, more to follow on tomorrow morning. As well as working 12 hour days, Harry has already had a chat with the neighbours to let them know that they will be working over the weekend, too, on both days. The insulation is due for delivery tomorrow and they will be putting the pipes that carry the service cables into this, along with the UFH pipes. I'm not sure when the steels will arrive, but that must be also imminent as the piles will need to be tied in before the concrete is poured. The building inspector is coming on Monday to check out everything before the pour. For interested parties, THE CONCRETE POUR IS CURRENTLY SCHEDULED FOR TUESDAY. I've read a couple of horror stories and some not-quite-horror-but-not-very-nice-stories about uneven slabs, so I've told Harry that before they leave site, I need him to demonstrate with a laser that everywhere that a wall rests is absolutely level and within tolerance. Harry is a man of few words and he didn't quite bat an eyelid, but I explained that I would much rather that something like that is demonstrated rather than just verbally assured. He seemed fine with it. So, one final picture of the hardcore going down, from the garage side of the house. More blow-by-blow action to follow tomorrow.

    Ducts in slab sub base

    Spent the weekend setting out our house. Hired a theodolite. Turns out theodolites have gone digital in the 23 years since we last used one ? but a You Tube video helped and we spent a joyous 3 hours setting out all the corners of the house. Amazingly, we have dug pretty much in the right place. And we feel more comfortable setting out accurately rather than measuring from a vague boundary hedge. MBC on site Wed / Thursday (in theory). Our sub-base is going in now (MBC doing the top 150mm MOT type 1). Just wondering about ducts. for water and BT. We also need to run the electric armoured cable in. We know we should have posted this question earlier. It has been bothering us for weeks. Site plan looks roughly like this. Its a weird shape (cut off a larger house behind). Plant room is shaded in yellow. Intended route of water (blue) and electricity (black, from kiosk) shown. Both go under the garage slab so we are ducting that tomorrow. Do we run these ducts at 700mm deep to the plant room and then up into the plant room? i.e. is the bit I am filling with around 300mm subbase as I type going to have to be dug out to put these ducts in? Or do they rise slowly and then go in the final layer (which MBC are laying)? BT duct is another question but please help us sort out water and elec first. Thanks.

    Time to dig deep

    As I'm getting the roof taken off the bungalow next week, I thought that I had best get my site insurance sorted out. When I was ringing around for quotes, every organisation asked whether the build would need piles in the foundations to which I answered in the negative as I had not heard anything to the contrary. HOWEVER, the lack of information in one area doesn't equate to certainty in another so I contacted MBC for some information from their SE as to whether he felt, at this stage, I would need to have piled foundations before going ahead and purchasing insurance. The SE, via MBC, got back very quickly indeed. This is the plan of our site with the existing and new structures superimposed, as well as where hedges and trees have been. The handwritten comments are self explanatory, but the orange areas are where the excavation needs to go much deeper than usual, probably about 1200mm, then back-filled with hardcore. Zarucki Fill_Excavation Depths.pdf So, to dig deep or to go for piles? The SE has said that both will work and the deciding factor is which is cheapest. In the sums I will need to do next week, I will also need to account for the cost of getting any piling system designed as MBC don't do this, then also getting the piles, foundation and super structure all connected up; please excuse the lack of technical terms. At the moment, I have no idea of what piling system would be needed, but if it's anything like @recoveringacademic experience, then it could be a process that requires a piling mat meaning I'll have almost formed the MBC foundation anyway. For those who want to read about Ian's experience, his excellent blog account of piles is here: Recovering academic's pile blog Of particular note is @Calvinmiddle's comment about his deeper foundation on clay for an MBC build. At the moment, I'm heavily leaning towards the deeper foundation and no piles. I will check out the economics of it; if it's a close thing, I would prefer to avoid piling just because I feel more comfortable with the principles involved in the deeper hard core layer and it avoids involving yet another contractor. But who knows - until 10.00am this morning, I had no idea what a piling mat was and a week is a long time in self-building.
  4. Good Afternoon All. I seem to be progressing on my new build and I should have the Building Regs documents back from Potton in a few weeks. I am going to put them with my own drainage layout and Bingo ..the lorries can roll (or so i thought) After a talk this morning with Potton it seems that the bit in the Order that says THEY do all the layouts and stuff, is only applicable if you pay the extra for them to do the planning permission and all such like ...(sigh) I am OK with the drainage layout as its a "funny one"as we are going through our parents land to connect to all services .. ..about 50m in all (thankfully most of it in their garden, so we can do the work ourselves) What has reared its head is the "foundation plan" ...or "foundation engineer report" ...I had never heard the words until today from Potton. So I called up the company doing the foundations and they tell me they quoted (and expect it to be) they HAVE visited the site and we have got a soil report ....so.........100cm x 60cm / Beam and Block ...which from what I can see is a standard. They have told me they have never been ASKED to make an engineer report for a foundation Potton said they will give the foundation company the "Slab setting out plan" and "line and point loads plan" ? ....but I don't think that is the same So I guess what I am asking is... a) will the council expect this ? b) is it basically a drawing I could do? b) does anyone have something i could look at to get an idea thanks in advance Eddie

    Block and Beam Quote

    Hello Everyone, I am progressing with some quotes for the foundations for my Potton home. I must admit, the prices have me a little daunted as they seem to be a lot MORE than I was told about 6 months ago. I am not suggesting I am getting "shafted" but I want to run it past you guys to see what you think. I am building a Potton Timber Frame and have been advised that Block and Beam would be the way to go ....easier and more friendly on the surroundings (i.e better received by planners) The house area from looking at the architects footprint and adding on roughly 50cm around (I just did this to be on the safe side for my working out ...I am not sure if it actually done) ..I am coming up with an area of 121.81 Sq Metres with a Perimeter of 49.82 Sq Metres. Now I have the first quote and it is over £23k, I know this company is trusted and has done many foundations for timber frames...But does this seem expensive? I have snipped the basics from the quote below ..so you can see what it entails ...hopefully someone on here will know what some of the specifics mean thanks

    What ducting will I need

    Can anyone remind where I can find the post discussing how many ducts to put in before pouring slab as I cannot find it. I have so far: Main electrical incoming supply Telecoms (Phone and Tv for exterior aerial) Power to garage Power to gates and possible camera/intercom (in separate duct) Exterior lights (may come from detached garage but I realise better control from house) Water Duct from plant room to kitchen island electric and water (internal duct) ASHP (water and power) Spare All these will basically come up in the plant room and some may never be used but better to have them in when we pour the slab. Any others that people have put in or wished they have put in or can point out the thread I cannot find.TIA
  7. Thanks to the members of buildhub for the constructive advice and a good ground worker we have managed to get our foundations in. The archeological watching brief wasn't the problem we had feared and nothing was found to delay this first step of our build.

    EPS layering / DPM

    I've realized we have the available height to add an additional sheet of insulation under our 100mm ground floor slab. Originally I had planned on using 2 x 100mm EPS70 with the DPM underneath as stated by Jabfloor. If I add an additional 100mm sheet on the bottom would there be any issues using it as a blind and sandwiching the DPM above it but below the upper two sheets? Consensus seems to be EPS can get wet - but Jabloor to state DPM first then EPS hence the doubt... Also any additional issues going thicker with EPS70 rather than one of the denser variants? thanks
