The unit rates quoted by contractor shall invariably include cost of transportation of rubber removed to outside MOD land. (iii) In any way Emeregency condition, the machine ( along with workers) should exit from the Runway in less than 3 minutes without leaving FOD. (iv) Friction Test should be carried out before and after Rubber Deposits removal operation and proper record of result duly signed by Enginner-in-Charge shall be maintained. The requisiste friction test machine will be arranged by the contrator on this account. (v) The cost of repair due to damage because of water blasting cum vacuuming system, if any to existing surface of runway the same will be repaired with appropriate material and procedure within 8 hours of damage or before starting of flight operations whichever is early and the same is deemed to be included in quoted rate and nothing extra on this account is admissible. (vi) The contractor shall give a demo of procedure and working of water blasting cum vacuuming machine for removal of rubber to the Engr-in-Charge before starting of the work.
