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 were in the form of tubes of plastic explosive left over from a Bureau of Mineral Resources seismic survey of the area. The bunker work proceeded so well that the task force was able to assist KCG with its pit excavation work. Some instrument bunkers contained steel cubes. Getting them into the holes was tricky because they weighed , and the largest available crane was a Coles crane. They were manoeuvred into place with the assistance of a TD 24 bulldozer. The Coles crane was also used to erect the two shot towers. Concrete was made "in situ", using local quarry dust, limestone and bore water. The Canadians erected metal sheds of a commercial design, which were used to assess blast damage. A tented camp was built for observers at the post by the 23rd Construction Squadron.
