To reconstruct No. 1's existing runway as an all-weather strip, the bomb craters had to have the water pumped out of them and then be filled in. Sandstone from a quarry on northern Labuan was placed over the clay and sand subbase, and the runway was topped with crushed coral from the west coast of the island, and sealed with bitumen. The runway had 70 hardstandings for aircraft. With 70 also on the dry weather strip, the air base could accommodate 140 aircraft. The 9th Division's engineers also undertook a wide range of construction projects on Labuan. These included building of storage, new port facilities, bridges and oil tanks as well as surfacing of roads. A wharf for Liberty ships was begun on 18 June, allowing the first ship to berth on 10 July. A fuel jetty was in operation by 20 June, and a fuel tank farm with seven tanks was completed on 12 July, as was a 600-bed hospital. Work then began on a 1,200-bed general hospital. The 2/4th and 2/6th Australian General Hospitals were transferred from Morotai to Labuan during July, though the later unit's hospital facilities were not completed until 17 September.
