of bunkers and other facilities dispersed over an area of but sited to within an accuracy of . The work force could not be fully assembled before 1 March 1956, but the facilities had to be ready for use by the end of July. provided Bloomfield with a list of required stores and equipment. These ranged from timber and nails to drafting gear and two wagon drills. The task force, which began assembling in February 1956, included a section from the Royal Australian Survey Corps, a troop of the 7th Field Squadron, detachments from the Royal Australian Navy (RAN) and Royal Australian Air Force (RAAF), and a civilian from the Department of Works and Housing. Their first task was establishing their own camp, with tents, showers and toilets. A team from the South Australian Department of Mines sank a series of bores to provide water. Like that at Emu Field, the bore water was brackish. Two Army skid-mounted Cleaver-Brooks thermocompression distillation units provided water for drinking and cooking. Work on the facilities themselves got off to a slow start, as KCG was running behind schedule, and unable to release promised earthmoving plant. Some graders were used by day by KCG and by night by the task force. A call to Blomfield resulted in a grader being shipped from Adelaide to Watson two days later. The arrival of a 23-man detachment of the Radiation Detection Unit of the Corps of Royal Canadian Engineers was expedited so they arrived in June, and were able to pitch in with the construction effort. In July, supplies coming from the UK were delayed by industrial action at the port of Adelaide. The work involved laying, testing and burying some of control cable. Each spool of cable weighed about , so where possible they were pre-positioned. The trenches were dug by a cable plough towed by a Caterpillar D8 tractor. In some cases the limestone was too hard for the plough and the cable was buried by using a grader to cover the cable to the required depth. A similar procedure was followed for laying of power cable. Some 1,300 scaffold frames were erected for mounting instrumentation, held in place by 33,000 anchor pipes. Bunkers ranging in size up to were excavated with explosives and a compressor mounted on a four-wheel drive 3-ton Bedford truck connected to the jackhammer part of the 4-inch wagon drill. Explosives
