The ability to juggle tasks, labour, contractors and materials orders is a skill every earthship builder should cultivate within themselves. As we start to involve contractors, it is a challenge to co-ordinate volunteer input on the site in order to get the site ready and to the right spec for the arrival of the contractors, materials or machinery. A lack of building skills has come to the fore a few times - but I've learnt a lot as a result. Every week that passes just now shows great progress on site. The berm is now closer to its final shape, the front timbers are on and the roof arrives next week. We've also got plastic sheeting in where the glass should be which is giving us some thermal mass activity inside the building. It's really looking like an earthship now!
