Completion, handover, and Defect Liability Period (DLP) monitoring are critical responsibilities of the Authority’s Engineer (AE) or Construction Supervision Consultant (CSC) in Engineering, Procurement, and Construction (EPC) mode highway projects. These activities ensure that the project is completed as per approved designs, specifications, and contractual obligations, handed over in a fit-for-purpose condition, and systematically monitored during the DLP to address any deficiencies or non-compliance with performance standards.
