Ouch.
I could see this decision impacting the affordability of the UBC Extension.
InTransitBC's bid always included cut and cover.
It was the theoretical Multiple Account Evaluation / Project Definition Reports that suggested a bored tunnel.
I doubt InTransitBC would be on the hook - maybe for traffic planning or taking longer than previously publicized, but not for the construction method.
See my previous post from February that the Request for Proposals did not require a bored tunnel:

There was no construction method specified in the Request for Proposals.
Read the RFP here:
http://www.canadaline.ca/pubLibDocs.asp?ID=4#19
The proposals submitted by the proposers specified what and how they would build to satisfy the project needs.
It was a design, construct, operate, maintain and finance agreement.
That's why there was so much variation in the proposals - it's not the same as a tendering process where the exact specifications are set out to be bid against. The RFP process allows flexibility for design and construction (basic elements are established but not particulars) - and resulting cost advantages or impacts.
Any enginering studies and evaluation studies conducted by government before the RFP process are internal studies for information only -
For example, read the Project Definition Reports, here:
http://www.canadaline.ca/pubLibDocs.asp?ID=5
so that government, etc. can figure out estimates of how much money may be required to build the project (how much do we need from the Feds, Province, etc.), feasability of options and other parameters - those studies are not generated by the successful proposer and each proposer can choose how it wants to fulfill the need.
Ultimately, the projects proposed by each proposer present what is proposed and what the government can choose from. If each of the proposers had proposed monorail, we'd either have a monorail, or nothing at all (as there's no obligation to proceed with a proposal).
