Vast John Horgan Dam is a monument to engineering, as well as NDP’s shifting stance
FORT ST. JOHN — The scale of the John Horgan Dam, the most costly engineering project in British Columbia history, is hard to fathom until up close.
The crest of the dam is more than one kilometre long. The six enormous pipes that channel water from the dam reservoir to power-generating turbines are each 11 metres in diameter. The powerhouse, spillway and dam buttress, or foundations, involve a total of two million cubic metres of roller-compacted concrete.
The buttress alone involves about 1.7 million cubic metres of concrete, more than five times the amount used to build the world’s tallest building, the Burj Khalifa in Dubai.
Perhaps just as impressive is the scale of the political reversal the dam previously known as Site C represents for the governing NDP, whose former leader, John Horgan, once criticized the project for being among “B.C. Liberal hydro boondoggles.”
