Attachment 10 Estimated Work Items for Each of the Ordering Periods_23JAN26.xlsx

This is an estimated work items schedule for a five-year drydock repair contract for the USCGC Polar Star spanning fiscal years 2026 through 2030. The document lists 110 work items (WI) organized by fiscal year, with quantities specified for each ordering period. Core maintenance activities are repeated annually across all five years, including drydock, temporary services, project management, dock and sea trial support, hull plating inspection and testing, propulsion hub maintenance, and various equipment inspections and certifications (elevators, fire suppression systems, cranes, davits, and generators). Specialized work items vary by fiscal year and include major overhauls, preservation work, tank inspections, and remediation activities, with quantities ranging from single occurrences to multiple instances per fiscal year.

The work spans propulsion system maintenance (shaft removal/reinstallation, gear maintenance, seal overhauls), hull preservation (underwater body preservation at varying percentages, stern tube treatment, freeboard plating), tank operations (fuel, ballast, aviation fuel, potable water), environmental and safety compliance (asbestos abatement, lead-based paint remediation, fire prevention), and specialized technical services such as NACE Level 3 independent inspections and inclining tests. Notable multi-year initiatives include lead-based paint remediation (five instances across the period), asbestos abatement (two instances), insulation and sheathing renewal (three instances), and gooseneck overhauls ranging from 3 to 23 occurrences per fiscal year, reflecting the complex and extensive nature of maintaining a major Coast Guard cutter over this five-year maintenance cycle.
