Reference_Doc-Historical_Average_Tons_Per_Container.docx

This is a reference document supporting a solid waste transportation and disposal services Request for Proposals issued by the City of Seattle through its Seattle Public Utilities department. The document contains historical data on average tons per container, which serves as a baseline metric for evaluating waste volumes and projecting containerized garbage transportation requirements. The reference data is intended to assist proposers in understanding the typical loading parameters and capacity planning for compacted, containerized garbage that will be transported from SPU's transfer stations and City-authorized customers to approved disposal facilities. The contract encompasses long-haul transportation and disposal services for non-recycled solid waste generated in Seattle, with services including container transport, material delivery to disposal facilities, and return of empty containers to maintain required inventory levels. The resulting contract is estimated to have a total value between $350,000,000 and $450,000,000 over the full contract term, with this estimate provided for general planning purposes only.

The historical tons-per-container data provided in this reference document allows proposers to establish realistic operational projections and cost estimates for bid preparation. This supporting documentation is critical for calculating transportation costs, determining fleet requirements, and forecasting capacity needs to accommodate projected tonnage growth while maintaining operational flexibility. The City seeks cost-effective, environmentally responsible, and operationally reliable solutions that maintain service reliability and support adaptability as regional landfill and infrastructure conditions change. All technical requirements are contained in the contract appendix, and proposers are encouraged to submit innovative approaches and beneficial alternatives aligned with City priorities.
