This is a lose, lose in my opinion, especially with Ephesus being in our back yard and the impressive work they have done; i.e., two most recent Super Bowl venues, more in the immediate future, new billion dollar stadiums, etc.
Obviously, I haven't an idea of the potential stringent "liquidation" type penalties/expenses they'd face for missing the deadlines, but I can't blame them if they are legit due to this unforeseen pandemic and relative labor, product/supply chain type issues that weren't foreseeable when the agreement was made. Therefore, their reasoning for wanting to add the "force majeure" language. Appears to be just more of the typical cut throat BS, etc. that is so commonplace in the construction industry, and where the GC/Construction Mgr. uses its upper hand for its sole benefit.
