Note :- The tenderer shall take following points into consideration and are deemed to be included in quoted rate:- (i) Due care shall be taken for friction parameters during application of PME as per ICAO (International Civil Aviation Organization) standard. (ii) The work shall be carried out through authorized and qualified applicator of PME manufacturers. (iii) A performance guarantee certificate for 3 (Three) years shall be submitted by the contractor to the GE on completion of work as specified. (iv) Application of PME shall be done by flooding and wiping in both first coat and second coat with the help of wiper or as directed by the manufacturer. (v) Application of PME shall be done under the supervision of manufacturer’s technical experts. (vi) Skid resistance test (Dry and Wet Condition) in every 5000 Sqm area of runway shall be carried out before and after PME by the Govt approved lab/by expert technician of PME manufacturer as directed by GE. (vii) PME required more/less than 0.89 litre/Sqm (undiluted) during execution of work as per direction of Engineer- in-Charge shall be measured and paid as supply only rate.
