Just looking at the piers, they have 38 costing about $79,000 each, these things are 9.5m high and are required to support 345 tons! The best statement in the Preliminary Basis of Design is, "Foundations are considered with good soil, with no piles."
Running my own numbers just for the piers, I calculate $291,000 per support, with 40 supports $11,640,000 per km.
Including all the other values un-adulterated, $39,816,000 per km, for construction only, which is on a par with high speed rail.
With an operating speed of 1,000kph I would support TransPod over High Speed Rail, a much more intriguing transportation system, however in the Alberta climate it should be below ground to eliminate the thermo-dynamic issue, as Hyper Loop has done with The Boring Company.
