Solid Waste Transportation and Disposal Services – Performance Documentation

This reference document is a performance tracking spreadsheet for the City of Seattle's Public Utilities Department (SPU) solid waste disposal and long-haul transportation services contract. The spreadsheet captures monthly operational metrics and financial data for 2024 and 2025, tracking disposal tonnage, vehicle turn times at transfer stations, trip duration performance indicators, manual ticket adjustments, and associated payment calculations. The contract requires the transportation of compacted, containerized garbage from SPU's transfer stations to approved disposal facilities with return of empty containers to maintain inventory. Key performance metrics tracked include total trips per month, average turn time in minutes, counts of trips exceeding 30 minutes, trips under 10 minutes, and manual ticket adjustment percentages. Performance data is collected from multiple customer sites including North Transfer Station (NRDS), South Transfer Station (SRDS), Rabanco (RAB), and Recology Cleanscapes (RECO). The 2024 performance section documents actual results, while 2025 data shows ongoing operational tracking through December. The detailed transaction log at the end of the spreadsheet provides individual trip records with ticket identifiers, truck operators, container information, scale weights, and precise time-in/time-out data for performance verification.

The financial component of this performance document reflects a complex fee structure with variable rates applied based on measured performance outcomes. Disposal payment is calculated based on net tonnage with rates that vary by rating period, with the 2024-2025 period showing a Measure 1 rate of $2.552 per minute and Measure 2-4 rates of $2.237-$2.190 per minute depending on the specific period. The spreadsheet details monthly deductions for turn time performance failures, with negative adjustments ranging from approximately $1,900 to $19,800 monthly based on turn time exceedances and performance thresholds. Year-to-date 2025 data shows total disposal tonnage of over 21 million net tons with cumulative performance deductions of approximately $142,000. The document references both Excel and PDF payment authorization amounts, with monthly invoicing ranging from approximately $1.5 million to $2.0 million. Additional line items tracked include disposal underweight charges, load credits for containers exceeding 28 tons, adjustments for unacceptable waste, and rail diversion or delay charges. The incumbent contractor performance is monitored continuously against established benchmarks for turn times, with the data indicating the contract operates under an ongoing performance-based compensation model tied to operational efficiency metrics.
