Here's how I read it...
Green Line Board made recommendations to Executive Committee of Council on project design, delivery strategy, and capital funding. My guesses on those recommendations:
Project design - Something BIG is changing (fewer stations, smaller tunnel, single track to Shepard), I don't see them not going to Shepard but maybe they only build out the track and not the stations?
Delivery strategy - Maybe they've cut it up more, I mean by the time you'd be building out the stations to Shepard there's going to be another opportunity for funding so I could see them moving to additional phasing?
Capital funding - Feds and Province aren't giving more money now but can the city find more money to tie them over to the next funding opportunities?
The updates said the recommendations were based on value engineering, design optimization, and contractor negotiations. :
Value engineering - These should be barebones stations, if they can rewrite a bylaw for noise for the Event Centre, maybe rewrite your public art bylaw haha.
Design optimization - Going with the most optimum design is a no brainer. Nothing fancy on this line.
Contractor negotiations - I'm sure there was some real talk in these negotiations, these projects have become fairly risky for contractors.
