Project Hughes Engine Cooling System Flush & Repair

The Alaska Energy Authority seeks a licensed contractor to perform a complete flush, cleaning, and repair of the diesel‑generator cooling system at the Hughes Power Plant. The work includes draining existing coolant, pressure‑washing radiators, replacing expansion‑tank components, revising minor piping, installing new hoses, and refilling with a 60/40 ethylene‑glycol mixture, all while coordinating limited outages with the local utility. The contractor must provide a lump‑sum price, submit required submittals, deliver daily progress reports with photos, and comply with Alaska prevailing‑wage and insurance requirements. • Drain, flush, de‑grease, and pressure‑wash diesel‑generator cooling systems. • Replace expansion‑tank pressure caps, gauges, and small‑diameter hoses per drawings. • Fill system with pre‑mixed ethylene‑glycol coolant and verify proper operation. • Provide daily progress reports, maintain community power outages, and meet all regulatory (Mini‑Davis‑Bacon, insurance, debarment) obligations. • Complete work (substantial completion) by November 1 2026.
