4.As per the rules in force, Registration is being done by the SE, PWD/WRD for class I to class IV and EE, PWD/WRD for the Classes V. While the registered contractors are participating in tenders and are being received by the Engineer in Chief, Water Resources Department and Chief Engineer (General), Public Works Department for scrutiny and placed before the Tender Award Committee for approval. It seems that many of the contractors have not renewed their registration by providing Income Tax Clearance Certificate, GST, Encumbrance Certificate, Solvency Certificate etc. In many of the cases the contractors have failed to keep their registration alive. If the registration of contractors is done by the Engineer in Chief, Water Resources Department and Chief Engineer (General), Public Works Department, in a single window manner, it will be quite effective to monitor the registration of all the PWD /WRD contractors throughout the State of Tamil Nadu and it will be easy to verify the genuineness of the records furnished by the contractors for registration. All the particulars regarding the contractors registered hitherto in the respective Circle/Division offices along with relevant files and registers shall be handed over to the Engineer in Chief, Water Resources Department and Chief Engineer (General), Public Works Department, Chennai – 5.”
