  1. I didn't realise quite how long a while since the last blog entry so time for an update as I'm on an admin day today, not least for the electricity supply which I'll come onto later. So, what's occurring? I'll start at the bottom and work my way up: Groundworks - the groundworkers arrived on site the day after the last May bank holiday, 29th May. They took the roof off back in April to sort out any potential bat issues and now they're back doing the main job. The old concrete garage block came down first. The roof panels have asbestos and have had to be properly disposed of, which has been done at a reasonable price of £650 rather than the c. £1300 I was looking at a couple of weeks ago. All done properly and I have my disposal certificate but without having to resort to sending stuff all the way to Swindon and get charged for 2 tons when it was just over one. A small result; still expensive but less than it could have been. My ground worker arranged this with one of his contacts; PM me for details if anyone local needs the details. The concrete sides of the block are all down but we've left the floor in place as it's a ready made hard-standing for everything that will be arriving on site over the coming months. It's mainly parking, portaloo and site cabin taking it up now. I will need to get some hardcore compacted down going further into the site as I'm not sure it will stand up to all the heavier construction traffic that is due. Demolition of the building will be finished this week, but there's still the old septic tank to be dug out and a bit more concrete from where there were sheds in the past. Next up is digging out for the insulated slab, drainage and services, not to mention the piles. I have my groundworker until the end of next week before he's due on another job, so we should get a fair bit done by then. I reckon the initial excavation will be a little rough until we've established the levels, which seems a bit chicken and egg to me at the moment. How can you mark out how deep you need to go when there's a whole lot of earth in the way? Fortunately, there are some useful markers on the site that I can use as references for the setting out of the perimeter but I will get everything checked out before the piling guy arrives and have any remedial excavation done for that. Speaking of piles....I've ditched the idea of the helical screw piles. Not because they weren't lovely enough, but because they were outrageously expensive compared with other, more traditional systems. The initial design drawn up by my SE would have cost more than £42k for the helical screw piling system which seemed like mad money to me, probably because it is. I had a chat with a contact and he said that very little of this kind of thing is done now, certainly on house projects. When it first came out it was embraced with open arms by the telecoms industry for ease and speed of use, but they have dropped it almost entirely now on cost grounds, and I can see why. My initial quote for CFA (continuous flight augur) piles came in at just over £15k which was far closer to what I was expecting. I reckon that in the end, with SE fees and everything it will come in at around £20k for the piles. As mentioned in a previous entry, the alternative was to dig to at least 2m depth over the entire footprint, which in itself is an expensive exercise due to the cost of muckaway (I estimate an additional 15 tipper loads), so swings and roundabouts, the piles aren't as extreme an option as it first seems. I've used Mini Piling Systems Ltd for the piling system - nice people, easy to deal with, based in Bath, will travel. I should add that because these are mini CFA piles, as long as the ground is dry and reasonably level when they come to put them in (July), there is no need for a piling mat as the rig isn't considered a large one. Moving upwards, the other thing that has slowed is getting drawings from holy trinity of architect, SE and MBC to the sign-off stage. The SE has been very efficient and have turned things around very well. The architect and MBC have been slower, but I'm going to hold back some criticism because were I in the shoes of the architect, I would probably be doing this amount of nit-picking on behalf of my client and I'm sure that I will be glad of it. As ever, just because an architect designs a house and it gets planning permission, that doesn't necessarily mean that it can actually be built. In my case, there have been delays in getting the small details that can be glossed over in the desperation to see physical progress and having something coming out of the ground, and this is what the architect has been pushing back on. They are determined to make sure that the proportions of rooms are consistent with the original design. For instance, the ground floor ceiling height has been raised so that the large open plan downstairs doesn't feel oppressively low due to its large area. As a result, most of the ground floor windows will also need to be increased in height as will the front door. This all has a knock-on effect, hence the delays. There has also been back and forth over the balconies and warm or cold roof construction and the parapet wall around them; we're not quite at the end of this but pending a response from a supplier, we are close. The issue is that the common solutions to ventilating the cold roof would look ugly. Everyone has gone to a lot of effort to make the house as good looking as it can be and it would be a shame to rush through this detail and then sit looking at ugly vents on the balconies for ever more. But, tick, tick, tick, more time passes. By far the biggest issue is that until these details and corresponding drawings are signed off and I pay a stage payment to MBC, my manufacturing countdown doesn't start. Standard time for MBC to get on site is minimum 6 weeks, this time of year more like 8 so I'm realistically looking at end of August or early September. Then there are the windows to go in and roof to go on. I really, really want the build to be weather-tight before the weather breaks in the autumn, as it will. Moving on to making the building work as a home, and for construction to actually take place, I'm sorting out the electricity supply at the moment. There is a live supply to the site as there was an existing dwelling there. Last year I contacted the DNO and had a service alteration done, which basically chopped the wire running into the bungalow and moved it all into a box on the pole with the overhead cable running down it. I rang the supplier at the time and advised them of the changes being made and arranged for one of their bods to come along and collect their meter. Sadly, they didn't turn up for the appointment, so now their meter is buried at the bottom of a pile of builder's rubble in the local landfill site. This put all sorts of twists into their collective knickers and it's taken the best part of a day to sort out how to re-establish the connection. It turns out that what's needed is a temporary building supply and this is always done through the commercial team. I've been quoted up to 12 weeks for the whole thing, but this is if you are applying for an entirely new connection, not just to get a meter installed. Even so, it could take around 4 weeks. We shall see. In the meantime, I've (for the time being) decided on getting my kitchen from DIY Kitchens. I've planned it all out and know what units I want and where, so I'm not going to think about that again for a while. I do, however, need to start thinking about lighting schemes and bathrooms/wetrooms as I've made very few decisions on these. Needless to say, there is a huge amount of other small detail going on but little of which can be done until the final drawings are in. Never a dull moment, though, my groundworker has just called to tell me that they have bent over a water pipe to stem the healthy flow of water that was coming out of it when they went to remove it, despite Wessex Water having sworn faithfully to me in February that the water was all turned off at the meter and that nothing should be coming out of anywhere. Off to make some more calls and demo photos to follow soon. Ta ta for now.
