ABSTRACT
Engineering works such as buildings, bridges, roads, pipelines and tunnels require very precise dimensional control during their construction. Buildings must be vertical, long tunnels must end at the correct place, and foundations must often be constructed in advance to accommodate prefabricated structural sections. To achieve this, surveyors are required to determine the relative positions of fixed points to high accuracy, and also to establish physical markers at (or very close to) predetermined locations. These tasks are achieved using networks of so-called control points. This book aims to give the civil engineering surveyor all the necessary theoretical knowledge to set up, manage and use such networks for the construction and monitoring of large or small engineering works.
