When the early input team arrived on site at the end of winter one of the first jobs was to flatten out all the wind tails in front of buildings and containers and in all other working areas. The snow surface for the construction site and the main thoroughfares was compacted and groomed to provide a hard and safe working surface for men and machines. Each of the modules was then dug out of their wintering positions. To do this a huge amount of snow was removed and battered back around each module to provide working space. A shallow ramp was also formed in front of each module to enable it to be towed out to its new position on the summer construction line. Before towing the clad module the jacking concept was first tested. To do this each leg had to be raised, a 1m high pile of snow pushed underneath and then the leg lowered on to the pile before repeating the process on the next leg. Once all four legs were sitting on piles of compacted snow (no mean feat for a building weighing approximately 60 tonnes) the module then used its hydraulics to raise itself to a full operating height of about 4m. This allowed a bulldozer to get underneath and level the snow surface all around the skis providing a working surface for the team to fit the towing frame. Once the towing frame was fitted the module was lowered and a CAT Challenger together with a bulldozer were hitched to the front. The module was towed slowly up the ramp to the construction line.

The skis do stick to the ice but once this “sticktion” is broken the module moves very easily. The same jacking and towing regime was followed for all of the tented modules. The only change in the process was the tent skirts had to be raised and secured to allow access to the skis. Once on the construction line the modules were ready for the next stage of construction.
