This opportunity is designated as a Total Small Business set-aside, restricting participation to qualified small business concerns. The contract requires completion within 450 days of the Notice to Proceed, with the contractor required to run the new generator for at least 250 hours during a minimum 6-month warranty period. The existing generator being replaced is an Olympian/International brand unit housed in a utility building with white exterior walls and louver ventilation, as documented in the provided photographic references. The scope includes specific spare parts requirements such as diode rectifier assemblies, valve cover seals, filters, fan belts, and pre-programmed control panels, along with specialized tools including an engine barring tool. Performance will take place at the U.S. Embassy facility in Dili, Timor-Leste, with the contractor required to coordinate closely with the embassy's Facility Manager and minimize service interruptions during the replacement process.
