This Q&A describes a Cambodia-based transportation requirement for about 100 personnel, with lodging around Phnom Penh, arrival/departure at Techo International Airport (KTI), training at the PKO Training Center in Kampong Speu, and a one-day cooperative event near Kampong Speu. Pricing should use the anticipated service period of February 10–28, 2027. A SAM-registered U.S. prime may use a properly licensed Cambodian transportation subcontractor not registered in SAM.gov, with the prime responsible for subcontractors and collective prime/subcontractor experience accepted for transporting passengers and baggage. Defense Base Act insurance is required and must be obtained by the prime contractor, and either interpreter certification or documented English-Khmer bilingual proficiency is acceptable for dual-hat driver-translators. Vendors should plan flexible bus and van solutions, such as 40–50 passenger coaches and 9-passenger vans, for airport shuttles, PKO training transit, and an estimated four unscheduled services, with pricing encouraged for both continuous 24-hour driver presence and 24-hour on-call support van options.
