CHAPTER ONE
1.0 INTRODUCTION
1.1 BACKGROUND TO THE STUDY
Engineering Surveying is one of the branches of surveying which from the general express for any survey work carried out in connection with construction engineering and building project, it is a large scale topographical map survey which the basis for design of engineering works such as highways, railways, canals, tunnels, dams, pipelines and transmission lines.
In the word of engineering and environmental studies, surveying has been recognized as the inevitable operation been described as be the bedrock of every meaningful development. The greater part of its responsibility is seen from the various types of surveying which are all geared toward promoting route ways, convenience, accessibility and spatial declination of both natural and social environment. In addition, surveying means the activities of planning, designing, constructions, development and rehabilitation of roads, depending on the survey data required by the surveyor.
Route survey which is an aspect of engineering survey may be defined as the survey operation that is done for the establishment of the horizontal and vertical alignment of transportation facilities. It involved: planning, design and setting out of any route such as railways, highways, pipelines and canals etc. as obtained by a surveyor and it also involved the proper assessment of natural and man-made features.  
    In addition, this type of survey should be applied when there is need for alignment, expansion, or rehabilitation at any existing route (road) e.g. for traffic purposes. The reason is that route survey provides a plan/map that shows the alignment, details, profile and cross sectional leveling which depicts the nature of the terrain of a given strip of land which serves the purpose of location, design and construction of route networks.
    Good road network is one of the basic amenities needed by human being as movement is one of the characteristics of living things. There are needs for people to move from one place to the other and transportation of goods and services. Therefore for any meaningful development in a country, good road is a must.
1.2 SIGNIFICANT OF THE PROJECT
    It was discovered that the route from Oyun to olorun village moro Local government Ilorin, Kwara State, had been badly eroded and full of potholes; also, the road is found to be too narrow and needed to be extended considering the volume of traffic plying the road. Rehabilitation of this road should be carried out in other to increase its carrying capacity thereby increase the physical development and human activities therein. Due to these, certain information about the road must be acquired which calls for route survey so as to get the baseline data necessary for the road design.
The main aim of this project is:
To carry-out Route Survey of Oyun-Oloru road in Moro local government area, Ilorin, Kwara State
1.3.2 OBJECTIVES
In actualization of the said aim of the project, the following objectives
Were followed sequentially:
(i)    Reconnaissance which include office planning and field reconnaissance.
(ii)    Identification of existing features and adjoining roads.
(iii)    Stability of the ground controls to be use for orientation.
(iv)    Determination of centre line and marking of chainages along the centre line at an interval of 25m.
(v)    Marking out some selected points for the cross-sectioning at intervals of 3m to the right and left on the profile and also the edges of drainage was marked.
(vi)    Leveling to determine the height of some selected points along the road.
(vii)    Detailing by the use of a total station Mato NTS352R
(viii)    Plan production (graphical representation of the surveyed road way) drawn with appropriate scale.
(ix)    Reports write up.
