Two issues here :
1. If the events satisfy the definitions of a compensation event - which from what you say they do - then it is a compensation event and you can proceed to assess the effect by the criteria stated in clause 63. That adjusts the target Prices.
2. The Project Manager - not the Employer - only has grounds to disallow costs i.e. what the Contractor is actually paid and only if the costs are firstly Defined Costs and then, secondly, not Disallowed Costs. So you need to check the definition of Disallowed Cost to see if there is anything the Contractor has or has not done which disallowed. Otherwise, the Contractor is entitled to the full Defined Costs + Fee for the Employer not doing what they said they would do ... which is fair enough !!
