INTRODUCTION Design and construction of structures is a complex process. Defining the scope of work and the responsibilities of the involved parties by means of the contract documents is necessary to achieve a high-quality structure.

This document does not specifically address the inspection functions but provides direction on who should be conducting inspections. These responsibilities are subject to relationships between the parties defined in the contract documents.
