Intro

The general guidelines for pay are as follows, though this may depend on details. We are hiring at $37.50 for people who can do the build the following Seed Eco-Home 2 details, using their own skill and recruiting an unskilled assistant. In order to do this, the apprentice can use build cheatsheets from OSE. This means that a person is effectively capable of building an entire house from available materials - every single step including mechanical, electrical, plumbing, landscaping, and PV.

For unskilled builders who cannot read plans or cheatsheets, but can follow directions in building as an assitant - OSE can pay $15-25 depending on their proficiency. First time builders may earn $15, while people who can work 2x as fast can earn about $25.

The designer track is a level above this, and includes ability to build and organize/source materials. This includes extracting complete BOMs from FreeCAD, generating purchase orders, and submitting complete building packages to the building department at the plan check phase of a build.

The enterprise track means that a person learns to run crews. Typically, this means that the person can recruit workers, have them show up, order materials to a site, work with a client to assess their needs, collaborate with the design team or draw up build documents themselves, rent equipment and supplies such as skid loader, gravel, and concrete.

  • Drainage slopes - roof, piping, etc.
  • Wire gauges
  • Materials thickness gauges
  • Pipe size
  • Local code variations
  • IRC requirements
  • Colors
  • Straightness
  • Level and plumb
