WRT the Evergreen Line, it proceeded as a Design Build partially Finance contract.
Here's the Partnerships BC analysis of the contract (click "Project Report"):

A redacted copy of the DBF Contract and schedules is at that link under "Procurement Documents".
Here are the excerpts from that report which states that the private contractor accepted tunnelling risk
and will pay a financial penalty for each day that substantial completion is delayed past July 29, 2016.
The recent unexpected problems with soil conditions while tunnelling - which will delay the project
- are the responsibility of the private contractor consortium.
Note that the private contractor is building a single bore tunnel - which is an "innovation" versus
the Province's reference plan which was for a twin-bore project. This was said to speed up the schedule.
So in this case, had the Province proceeded with its own plan, the soil condition delays may have been encountered twice,
with a twin bore, rather than once with a single bore.
The current projected opening date is in Fall 2016
(Construction started in February 2013, with property acquisition and utility relocation undertaken by the Province before that.)
The contract requires TransLink to open within 1 month after substantial completion
- so backtracking 1 month to substantial completion, the contractor's penalties are for at least a month.
Here's the Press Release about the delayed opening and that the Contractor is responsible for the cost of the delay:
