Week 7 The Steel Roof Beam
On Monday the second gable is poured and most of the internal bracing, corner bracing and window shuttering is removed.
Tuesday rains all day so no work on site. The internal floor is under 1 inch of water with no way to escape, without us brushing it towards soil pipe. Good to know we are airtight at the floor/wall joint.
The steels are installed, we were supposed to have wooden roof beams but somehow this was not calculated by the architect who insisted the roof truss company would do the calculations later. The roof truss companys only want to do the calculations when they know you are ready to order and they said the beam spans could not be done. So on the last minute we had to go back to the SE who worked out our steel beams and the total cost of roof went up £8k. I wish the architect had suggested the SE looks at the roof calculations earlier but unfortunately we just have to move on from this, and up to this point we have had no other extra costs.
Since we are no longer working with the architect I have had to find a new SAP assessor who I can engage with as the build progresses. We have been discussing how changing the steel beam might change things as the vaulted ceiling can now be higher if we want. This gives us more space to heat up. I also wanted to know the effect of not putting as much solar on the roof or not having the wood burner changes the SAP results. Since having a smart meter fitted at home we have reviewed our current electric usage and decided that less solar (7.5 kwp instead of 11 kwp) but with the ability to add a battery.
Also I think aesthetically one row of 15 panels will look better.
Total Man days of labour week 7 is 16 days.
Total to date b/f £44925
New Design Stage SAP Calculations (previously done by architect) with ongoing advice about changes that will affect the SAP and to include the As Built SAP documents and EPC at completion £720. It does seem a lot compared to online prices but for peace of mind knowing that we can if we choose to only put 6kwp of PV on the roof instead of 11kwp, is an overall saving.
Total to date £45645
