The City of Tigard is seeking proposals from qualified contractors for the cleanup and environmental mitigation of homeless encampments on public properties after they have been abandoned or cleared of human habitation. Contractors will be responsible for a safe and clean site by removing large items, biohazardous material and other encampment waste material. The services required are on an on-call basis but would be scheduled with advanced notice. Work under the resulting contract will include: surveying sites, collecting debris, dismantling temporary structures, removal of trash, removal of human waste, and removal of all material. When transport and disposal is required, disposal must be at a site permitted to accept such materials. Encampment Sites are considered to contain a variety of materials that may contain hazardous materials, including biohazardous materials, garbage, general debris, human waste, constructed temporary shelters, and other items associated with homeless occupancy. Contractors must be trained in handling and disposal of hazardous materials.
