Careful planning of each project
Local residents, often through a community organisation, will decide when the project should occur. Times will avoid difficult work periods such as tropical wet seasons, hot desert summers or school holidays. The local community involvement will help to negotiate with different skin (or clan) groups and improve access to houses. There will be local knowledge about infrastructure services (power, water and waste) and local housing faults caused by the environmental conditions (eg high levels of mineral salts in the water will mean more plumbing repairs).
