Intro
There are several calculation types:
- Engineering related - structural. These are addressed and minimized by open source design and open source calculation methods: Seed Home 2 Structural Calculations, Seed Home 2 Brace Wall Calculations.
- Site adaptation - the only outstanding cost per distributed build is the appropriation of a build to a given site. Setbacks, etc, of a Site Plan. In the ideal case, the site is flat and we build exactly as shown in the plans. The possible adaptation may be for some construction details related to local codes, local climate, soil, and special conditions. Ideally, we crank these out in a day's work.
- Costs - materials, equipment, labor, overhead/legal/design
- Ergonomics of build - these go into the Costs of build

- Scaffolding - Home Depot rental - The platform is 5x7 and can be expanded up to 15 ft high (in 5 ft increments). It costs $162 per week or $405 per month. It would be expensive to rent scaffolding to wrap around the whole house, but it wouldn't be cost prohibitive to rent just one. The question then becomes whether this is too heavy and awkward to move around (which it might well be).
