Aerial view of Imperial Chemical Industries Alkali Beds - for description from newspaper see B9695/1. The clipping states "Simultaneously with the construction of the salt paddocks at Dry Creek, where salt will be produced from seawater by progressive solar-evaporation, the company is building extensive works on the northern side of the old shipbuilding yards at Osborne, where alkalis will be manufactured from brine made at Dry Creek from salt taken from the sea and pumped under Port River in a pipeline. The works will comprise 22 buildings. During the past two or three months a large part of the big tract of waste land at Osborne has been completely transformed, a new road has been built, the land has been built up and levelled with thousands of tons of filling, and the actual work of laying the foundations is almost ready to be started. Because of the nature of the soil at Osborne, the foundations of the works are of special design and it is expected that it will be between nine months and a year before this stage of the work is completed. The contract for this work, which has been let to Messrs. Essery and Cartledge of Norwood, for about 50,000 pounds includes the laying of about 8,000 cubic yards of reinforced concrete and the driving of 4,400 timber piles, each pile being from 38 to 44 feet in length and more than a ton in weight. The piles, which are of stringy bark, black butt and turpentine pine, have been brought from the Mount Lofty Ranges and from as far afield as New South Wales. So far about 600 piles have been taken to the site of the works, where they are being pointed and tipped ready to be driven into the ground. It is hoped that it will be possible to start pile driving within the next month. For this purpose a pile frame has been constructed and an automatic pile hammer driven by compressed air has been prepared. A large air compressor has been installed on the works to supply the necessary air pressure. Meanwhile excavation work is proceeding and of a total of 20,000 cubic yards to be excavated about 7,000 cubic yards has already been removed. Caterpillar tractors and horse scoops are being used. Each day between 230 and 250 cubic yards of earth are being removed".
