DESCRIPTION

The government authority in Longview, Washington seeks a vendor to provide and construct an archaeological wet screening system. The selected contractor will be responsible for building a functional screening system that includes mechanisms for water conveyance and sediment dewatering, ensuring efficient processing of archaeological materials.

The scope involves using mechanized equipment to transport stockpiled sediments to the screening platform and manage the consolidation of waste rock spoils. Screening equipment must provide features for discarding waste material onto the platform, using either a removable insert or hinged design to permit dumping. The project also includes site cleanup, utilization of web soil survey mapping to identify native soils, and implementing a catchment basin to recycle decanted water back into storage.

The contract will cover a period of one year.
