When the contractor submits the method statement with the client/consultant. When the client/Consultant approves it after useless three revisions. When the contractor submits JSA for the job based on the approved method statement. When the Client/Consultant approves the JSA after three more useless revisions. When the contractor applies for the permit to work based on the method statement & JSA. When the Client approves the permit to work.....by that time, the contractual time period to finish the job would expire & the client will stop the work following a penalty notice which will go to arbitration committee and then....... God Knows :P
