There was a very interesting documentary about this.

The 'civilian' parachutists prepare the runway.
Barneo is a seasonal camp, set-up in late March every year only through a highly complex and technical series of logistics incorporating Ilyushin-76, Antonov-74 and Mi-8 flights from Moscow and Siberia, parachute and skydiver drops, specialist advisers and observers and temporary camps on the Arctic Ocean. Once the ice runway has been prepared, using tractors parachuted onto the ice, technical AN-74 flights deliver the camp infrastructure and Barneo usually opens its doors to the first passenger flight around April 2.
