I would give:
- one early warning for the VOVID-19 virus … or more precisely would have as it is way past the time you became aware of it;
- separate early warning notifications as new issues emerge. A balance here is needed between notify what matters and is likely to impact versus notifying for absolutely everything which might possibly, but is very unlikely to happen &/or will have minimal impact which the Contractor can deal with without the PMs help.
- notify individual compensation events as & when they arise. These will be far fewer than the early warning notifications.
