Week 9 and 10 Roof OSB and internal walls
Week 9 and 10
The gable ladder is up, and the OSB 3 is installed over the rafters.
The overhang supports are shaped for the secure attachments and put up. The South side of the roof gets its cross batten. The scaffolding comes down, unfortunately due to miscommunication between the director of the company in the office and the director working on site the scaffolding comes down before the North side gets battened. The builder has given us the materials and refunded us an amount for the labour.
It was always our plan to try and get the foundations and walls put up by the same company, so there is no doubt about site measurements. During the tendering process we found it very hard to get a groundworks team who worked closely with a builder where the combined price was what we expected. We had builders who came and quoted then ‘ghosted us’, perhaps they didn’t like us living so close to the build or like that it was only a shell build.
One builder put his estimate in for both groundworks and the build but suggested his mates company could do the groundworks cheaper as he had his own equipment, but his mates quote doubled the first estimate. Which left us with little confidence in the builders estimate.
Getting a detailed estimates and quotes for groundworks, build and roof became nigh on impossible, and I was quite prepared to call the whole thing off or just do the bare minimum to secure the building works had started. We had still added value to our land and it would have kept our long term options of selling the land with the planning permission commenced.
Eventually we found a building contractor who could do the foundations and the build. Although I ideally wanted a dry shell before we took over the project managing, we are parting company with the builder sooner than planned.
This is partly due to his inflexibility of using only his choice of solar installer who wouldn’t put the solar panels on that we wanted. The builders solar installer wanted to install 6.52kwp but I had found panels giving me 8kwp and this was better for us and the SAP/EPC. The builders installer kept looking at an outdated list and saying the panels were not MCS certified. The panels only got their MCS certification in July and despite me telling him the MCS certificate number, checking with the wholesaler and MCS that they were ok he wouldn’t change his mind.
Due to the builders rising costs we decided we could no longer continue with his company and instead we have sourced our own roofer and solar installer, who will install the all black 500w panels I wanted. This has saved us over £12,000 but delayed work slightly as one lot of scaffolding had to come down on the Friday/Saturday and the roofer will put his own scaffolding up on Tuesday.
Total man days of labour for week 9 is 14 days.
Total man days of labour for week 10 is 17 days.
Grand total of labour from building contractor is 157 hours, this has been recorded by me just for reference it does not include any scaffolding, up or down. The actual cost was on a fixed price quote.
Total cost to date.
Brought forward £45645
Payments to builder for installing ICF walls, internal load bearing walls, stud walls and roof structure £95000 (ICF £15,000 apx)
Total to date £140,645
I have quotes for £20k for the roofer, £8k for the solar and £22K for the installed windows. If this all goes to plan thats less than £200k before internals start.
