war-damaged French harbors, particularly Dunkirk and LeHavre. This system provides for sinking an open-ended steel cylinder into the ground and excavating material from within the cylinder, both operations being performed by special patented machines. When the required depth is reached, a steel reinforcing cage is installed in the cylinder which is then filled with concrete, forming in effect a large diameter cast in situ pile. A maximum crew of about 260 men was engaged in constructing the foundations. One of the best known members of this crew was "Lucky," the Canary, whose duty was to descend into the gloomy depths of the Benoto shafts to test the air before his fellow operatives descended to carry out their task of excavating rock at the bottom of the shafts. His cheery song on his return to the surface was a sign that all was well in the depths and work could proceed. Shortly after the bridge was opened it carried an average of 37, COO vehicles daily. It is anticipated that this figure will rise to 62, 000 by 1965. This schedule of rates contract was started in November of 1957 and completed in June of 1961 and amounted to $6, 221, 648. 14) Aluminum Extrusion Plant Construction involved a 360 ft. by 80 ft. press shop; a 210 ft. by 62 ft. packing shop; offices; amenities building; store building, guardhouse; roads; footpaths; car park; electrical substation; complete sewerage and industrial waste treatment works; drainage system; and installation of process equipment. Installation included: 2,500-ton extrusion press on a 300-cubic yard concrete base; ageing furnace; die pre-heater furnace; 20-ton de-twisting stretcher; hydraulic pumps and motors; die-cleaning plant; compressed air supply and complete machine shop facilities. Utah's fully supervised and coordinated plan, turnkey, was responsible for the complete design and erection of this plant, from drawing board to operating plant. This cost plus project was started in November of 1959 and completed in September of 1961. The project cost $671,292. 15) Springvale Sewers Enlargement of sewer lines in existing residential area for Springvale and Noble Park Sewerage Authority in Melbourne, Australia. The lump sum project was started in November of 1959 and completed in March of 1960. The total cost of the project was $337, 079. Extreme rainfall during two seasons, together with difficulty in maneuvering equipment around fence lines, caused many problems on this project.
