First paragraph explains that only option left to City of Calgary is to build the tunnel after runway completion. The CAA has agreed they will no put up a building where the tunnel will be located or take other action that would preclude the tunnel being built.
That is the fact portion of my arguement.
The opinion portion of my arguement is that Tunnel supporters are hoping for a "Hail Mary pass" whereby the City forces the airport authority to delay runway construction while plans are reconfigured to construct the tunnel during runway construction.
I am also of the opinion thsat Nenshi all ready knows the Tunnel is past the point of no return. This is why Better Idea #4 includes the proposal to engage CAA and if the CAA will not cooperate, then move to replace the CAA board with puppets of City Council.

The runway is supposed to take about 4 years to build. The tunnel would not take 4 years to build, and would only affect a very small portion of the runway construction zone, perhaps about a section about 100m wide, when the whole runway is what, 4km long? So the tunnel would affect about 1/40th of the construction zone. Sure, it might affect haul routes and things like that, but that shouldn't affect the construction schedule.
I'm in the construction industry, and I can't see how building the tunnel simultaneously with the runway would affect the completion date of the runway in any way.
Even if the start building the runway from one end, the tunnel should be done by the time the runway construction gets to it, if they start at the south end.
Sure, the tunnel would have to start soon, but the deadline given by the airport to have it done was mostly just pressure by the airport I think to get it done, not that is was a hard deadline, IMO.
The tunnel, after all, is a relatively simple project. One of the larger construction companies in Calgary could probably get the shell done next year. Its a simple box with straight walls, lots of repatition in the construction sequence, and its in the middle of an undeveloped field, with no space issues. Engineering the runnel is not really a difficult proposition either, Even if the go ahead was given to construct the tunnel today, the engineering could be done (at least the detailsaffecting the actual tunnel) before the contractor could even get mobilized. The design of the roadway and the other smaller details could almost be done by then as well.
It's really a simple project, it costs a larger chunk of money simply because it is large.
