Hi! Sometimes there might be a delay due to the client not fulfilling the contractual obligation. eg. Providing Quarry and operation of Crusher Plant. However, the client is reimbursing you the additional cost incurred due to procurement of aggregate from open market. But this comes with uncertainty about availability with supplier, quality, cost, etc. In this case the time is not being compensated by client. How can we approach such subjective delays where quantification is not possible?
