The current plan is that everyone who makes up Stone and Webster, whichever entities that may be, will become WEC.
Fluor is being brought in to be the project management firm, at least for our project (V. C. Summer 2 and 3).
In all likelihood, craft/trade will see no changes other than the name on their hardhats. The management team here.......that may be an entirely different story.
I'll check back in as more info is provided to us.
