Seed Eco-Home 2 Wall Modules Build Cheatsheet Construction Set
How to break down instructionals for the Seed Eco-Home 2 in a modular fashion so that we can reuse smaller, common parts of the instructionals for all modules where they are applicable?
This emerges from Catarina's experience a few years ago, where she learned that it is more useful to break cheatsheets down to, say 2 parts. One part has material common to many modules, and the other has unique material.
It is true that this method can be taken to the limit to simplify instructionals/cheatsheets production greatly - and formalizing the common parts allows us to create an algorithm that can be used later when automating build procedure generation through artificial intelligence.
There are several specific aspects of wall modules. If broken down rigorously into common parts, instructionals production can be modularized. Thus, the key to success becomes an effective modular breakdown strategy and the resulting breakdown structure. We can begin the breakdown structure by recognizing known submodules of wall modules:
- 9' Frame - Of exterior walls, with 2x6 typical, there are many parts that are common - as most modules are 4' wide, with a similar structure. 9' modules have blocking.
- 8' Frame - Of exterior walls, with 2x6 typical.
- Exterior Sheathing - most sheathing is identical. However, there are cutouts that we can do prior to final assembly - which are done much more easily on a plain sheet as opposed to finished module, so it is likely a good idea in general to make the cut on a sawhorse than in position - where height or inaccessability may be an issue - especially on the second floor. Exterior Panels for exterior windows can be cut at the wall module build stage.
- Interior Sheathing - there are electrical cutouts and other apertures in interior panels - for outlets and devices such as lights. There is an interesting code issue here - in that wall boxes must be attached to walls in the rough electrical inspection stage. This means that cutouts in the inerior sheathing must (1) either be exactly located, or the electrical box must be moved.
- Interior Frame - 9' - 2x4 typical, with beaded plywood on both sides typical.
- Interior Frame - 8' - 2x4 typical, with beaded plywood on both sides typical.
- Utility Channel - specific structure for running wires from breaker box, plus for interconnecting modules
- Housewrap - specific details are required
- Electrical - Outlet Panels - specifics of electrical system. Outlets can be TR, exterior, interior, GFCI, AFCI.
- Electrical - Switch Panels - switches for lights
- Electrical - Light Panels - light outlets
- Gasket - weather-protective gaskets typically on one side of panel.
- Flashing - detail on water barrier for windows, doors
- Wiring - interconnecting electrical modules
