Third Party Inspection Manual

This manual presents process and procedures to conduct Third Party Inspection (TPI) activities for projects employing approved Trenchless Technology Techniques. Trenchless technique applications are generally state-of-art, and the project owners or implementing agencies and service providers often lack the appropriate technical competencies necessary for inspection, monitoring, and review of such projects on a holistic basis leading to inferior project quality and therefore the importance of TPI for Trenchless projects. The manual aims at providing the procedures for TPI activities, qualification framework of inspectors, training and certification program for Trenchless Inspectors, standard inspection protocols and process, inspection reporting requirements, and finally procedures for auditing the reports and inspectors.
