Alcan -- British Columbia power project under construction
Feb 1953 n 2 p 50-5: Intake tunnel is 53,100 ft long, 25 ft in diam; penstock of plate steel is 11 ft in diam; intake tower of concrete equipped with 14×26 ft wheel gate; penstocks and power house installed underground; normal output of each half of power plant is 815,000 hp but can be increased to 1,050,000 hp. June n 6 p 53-7: Main underground powerhouse chamber is 1140×81.5×139 ft; concrete arch over chamber was built prior to excavation; long-hole drilling methods were employed for excavation; 141 such holes, 4.5 ft apart, made up typical pattern for blasting; 400,000 cu yd of muck obtained from rock excavation used for various construction purposes.
