Nec 3 - Option B Cl.60.5

Option B - Cl.60.5 = The Contractor is claiming the impacts of Covid-19 have changed their original BoQ pricing. They have notified a CE under 60.5, however they have no Key Dates and Completion has not yet been delayed. Are they entitled to this CE ? Can you give a clear example of Cl.60.5
thanks

60.5 applies when there is change in quantities that delays Completion. Therefore the increase in quantities must be on or get on the critical path. This would have nothing to do with clause 60.5.

I suspect that they are angling for a compensation event under 60.6, but would need more details.
