Additionally - what is the project timeline impact for any major endeavor such as this with respect to supply and labor chain interruptions due to pandemic, Suez-tipation, other economic factors...

I recall reading that major construction, mfrg project timelines were automatically setback by a large number of months due to the Evergreen thing... (JIT construction required a precise delivery of components and even a few week hiccup in that caused a downstream of ++months)

OBV Boom isnt affected by such - but the labor version locally in the US (Colorado) could still have slowed...

The other non-tangible impact of something like this is the loss of intellectual momentum that a team may have had aggressively going after a timeline when suddenly all the eng team gets to go spend more time with family...

Just some factors to be considered.
