Whenever a Contractor assesses a compensation event - they have to price for the realistic risk that they can see and price for the event as they see it. If you do not have your subcontractor tied into the process you have to price it yourself. You cant retrospectively ask for more once the subbie is on board and identified something the Contractor missed. The only way of claiming more would be if it is a new CE e.g. additional works is a CE but then you hit unforeseen ground conditions that you couldn't have known about).
If you think about it - a Contractor tenders and commits a price for a whole job without entering into contract with any subcontractor. You can think of a CE as a mini tender in its own right.
