This is a Sources Sought notice for market research to inform the acquisition strategy for an upcoming RFP for airfield electrical and pavement rehabilitation upgrades at the Moses Lake Auxiliary Field, located at Grant County International Airport in Moses Lake, WA. The estimated magnitude of construction is more than $10,000,000. Work includes pavement rehabilitation of asphalt and concrete, in-pavement airfield lighting upgrades, and vault equipment overhauls including new constant current regulators and ALCMS panels. A key performance constraint is a maximum 60-calendar-day total airfield closure window between April 1 and September 30 in a single construction season, with specific taxiway phases limited to 14–21 days each and standard working hours of Monday–Friday, 7:00 a.m. to 4:00 p.m. (with pre-approved 24/7 operations). The government is seeking industry feedback on schedule feasibility and whether electrical upgrades should be performed under the same contract or a separate one, with interested firms asked to demonstrate capability via up to three project examples.
