PREFACE
This project is mainly concerned with the presentation of information basically on the structural detailing of reinforced concrete members of a story building, in a sloppy land with a retaining wall. Structural detailing is a branch of structural work that transposes the idea of works of a structural engineer into working drawings for easier utilization in the building construction. Working drawings are drawings produced by engineers for easy execution of a plan by builders.
The drawing also shows the interrelationship between the architectural and the engineering design, it shows all the construction detail properly as they relate to the other with no attempt of separation of diverse materials.

CHAPTER ONE
There is only one means by which information is transfer to a contractor in a construction industry, designers in the engineering sector communicate to each order by means of drawing and specification. Before any construction work could be done properly, there must be an engineering drawing mostly done by architecture in connection with the design being provide by the structural engineer.
It is the work of a structural engineer to design an object such as bridges, railways, dams, roads, buildings and so on. The design comes up in the hand sketch first after which the design are put together into a clear and presented working drawing used by builders or contractors often taken to the authority involve for approval.
The drawing will show the interrelationship of all the parks that go together to make the ground design drawing. All the general construction details are shown properly as they relate to the other with no attempt of separation of diverse materials.
A good drawing should provide the following information.
a. Overall dimension
b. Interrelationship of material, equipment and the space schedule of finishes
c. Doors and windows type and sizes
All detailing works developed by the detailer serves a good purpose of standing the risk of sudden of buildings. It also helps to avoid unnecessary delay of work, which may come up doubts and frequent clarification.
