PREFACE

            This is the presentation of an information on the structural reinforcement detailing of concrete members.  Structural detailing is a branch of structural work that transposes the idea or works of a structural engineer into working drawing or easy utilization in the building construction works.  Working drawing are produced an engineer for easy use by the contractors.

            The processes detailing put in place was in conjunction with the recommendations of the concrete society and the institute of structural engineers.  In building construction a good interaction and contractors are required.  The methods, scates, symbols and notations must be standardized and understood by all parties in a project to minimize risks and communication hindrances.

            A structure is broken down into identifiable elements for detailing work like bean column, slab etc which enables the different detailing  aspects to be fully addressed and understood.

INTRODUCTION

            Before a designer can relate his requirements dearly in a construction industry, a drawing is to be prepared; this is because the drawing serves as a general means of communication.  Thus, the drawing is adopted mostly, then other means of communication in engineering sectors.

            A structured engineer mostly engages himself in designs on construction of structures.  Like roads, bridges, railways, dams, buildings and other public works.

            The structural engineer makes initial designs, which are usually free – hand sketches of the work.  These sketches are used to make clear and neat working drawing, which will b e used by the builder of contractor after approval for construction by the authorities involved.

            The contributions of a detailer is highly significant to the construction process, for a well detailed drawing is a good medium of reducing the risks of building collapses and to avoid delays arising from doubts and too frequent clarifications.

            This project shows the methods and techniques needed for detailing of reinforced concrete structures.
