Foundation
From Bottle School Wiki
- Principal columns with footings (80cm x 80cm) are dug to a depth of 1.05m
- Other columns are placed at .85m; interlaced with the main foundation
- The main foundation is comprised of 3 3/8" rebar tied with 1/4" rebar every 20cm and poured concrete (H: 20cm W: 40cm)
- Three layers of block follow the main foundation
- Columns are poured to match the height of the three layers of block
- Finally the lower beam is poured
Footings
- Dig an additional 20cm depth below the main foundation trench and pour the footings for the columns prior to pouring the main foundation
- Footings are comprised of 3/8" rebar tied in cross hatch
