Week 6, Day 1:
- Ongoing progress on the below-ground blockwork walls.
- The perimeter walls are now complete but the internal walls need to be constructed to the same level before the floor can go in.
- Some of the internal walls (e.g. either side of the hallway) go all the way up through the house to help support the roof and are constructed using a single skin of 140mm blocks.
- Other internal walls are only there in order to support the floor beams, to avoid them having to bridge an excessive span. There’s such a “sleeper wall” across the middle of the Living Room.
- Delivery of the concrete beams for the beam-and-block ground floor.
- The blocks to in-fill the gaps between the beams arrived on Friday (Week 5, Day 5).
- Further work to back-fill the trenches for the GSHP collector pipes.
Week 6, Day 1
Concrete beams for ground floor being delivered
The concrete beams for the ground floor, supplied by Stressline, are more sophisticated than they appear at first glance. The longer beams have a wider ‘T’ section and more steel reinforcing wires as per the photos below.
 3300mm concrete floor beams with one steel reinforcement wire |  4300mm concrete floor beam with two steel reinforcement wires |  5200mm concrete floor beams with three steel reinforcement wires |
