Fore Sight (F.S): It is the sight taken on a levelling staff held at a point of unknown elevation to ascertain where the point is above or below the line of sight.
Intermediate Sight (I.S): This is the sight taken on a levelling staff held at a point.
Height of Instrument (H.I): It is the elevation of the line of sight with respect to the assumed datum.
Station: This is the point where instrument are positioned. They are also points of determining elevations.
Change point: This is the point on which both the fore sight and back sight are taken during levelling operation.
Cross section: It is the determination of the difference of elevations of the ground surface along line perpendicular to the center line of propose survey work.
GPS Global Positioning System: This is a means of measurement using satellite systems of positioning with the purpose of definition of co-ordinates.
Theodolite: It is an instrument used for angular measurement.
Foot Screws: They are used in theodolite levelling operations.
Circular Bubble: Used for setting the vertical axis of the instrument over a survey station.
Plane Bubble: Used for setting the horizontal axis of the instrument in the horizontal plane.
Circle Reading: They are graduated in degrees, minutes and seconds (0, 1, 11) which are used for angular readings.
Levelling Screws: They are used for setting the instrument.
Clamping Screws: Used for clamping the instrument in either vertical or horizontal plane.
Bench Mark (B.M): These are fixed references point, reduced levels of which are accurately determined by spirit levelling.
Reduced Level (R.L) This is the height or elevation above surface adopted as datum.

CHAPTER TWO
2.0 Â Â Â LITERATURE REVIEW
Route survey is to establish the horizontal and vertical alignment for transportation facilities which are assumed to form a network that includes the transport of people or goods by roads, highways, railways, pipelines and others. Route survey alignment planning, design and construction work includes obtaining necessary information regarding terrain and land use, making surveys to determine detailed topography and establishing horizontal and vertical control required for construction layout.
In general view, route survey consist of determining ground configuration and the location of objects within a proposed route, thereby establishing the linear alignment of the route and determining volumes of earthwork required for construction. The most important aspect in route survey alignment project is the establishment of horizontal and vertical control required for planning, design, construction and final as built surveys for the realignment.
With the advent of the Roman Empire, there was a need for armies to be able to travel quickly from one area to another and the roads that existed were often, which leads to poor movement of large number of people. To solve this problem, the Romans built roads which was with the use deep roadbeds of crushed stones as an underlying layer to ensure that they are kept dry, as water flows out from the crushed stone, instead of becoming mud in clay soils.
In the medieval Islamic world, many roads were built throughout the Arab Empire, the most sophisticated road were those of the Baghdad, which were paved with tar in the 8th century. Tar was derived from petroleum, accessed from oil fields in the region, through the chemical process of destructive distillation.
In the new construction method, 18thand 19th centuries; new roads and bridges began to be built, often based on Roman designs. Although there were attempt to rediscover Roman methods, there was little useful innovation in road building before the 18thcentury.
Roam road design using large stones at the bottom and gravel on top with depth of two meters was used by General George Wade 1725 and 1737 in constructing 250 miles (400km) of road and 40 bridges to improve Britain’s control of the Scottish highlands.
Route survey is also the determination of the part of a proposed road in order to portray the relief of the path and also the design and construction of linear works like road and pipelines or railways.
Of all roads is one of the most important infrastructure which can not be neglected. It plays a major role in the development of nations, because it aids a better road transportation management system also it serves a thoroughfare, route or way on land between two places which as been paved or otherwise improve for the transportation of goods and services
CHAPTER THREE
3.0Â Â Â Â Â Â Â Â Â Â Â RESEARCH METHODOLOGY
The methodology employed to accomplish the task include traversing and levelling method. This technique was used to determine the easting and northing co-ordinates of the route re-alignment and to obtain the co-ordinates for the route profile at the Chainage of 25m interval as well as to fix the existing details within 20m left and rights of the existing road. (A hand held GPS was also used to establish controls at every 1km of our project route). Â
3.1 Â Â Â AREA OF STUDY
The area of this project site is located at Federal Polytechnic Nasarawa, Nasarawa state, from the school gate to the school senior staff quarters which covers about 1.982km in total.
3.2Â Â Â Â POPULATION
The population of the road users which leads from the gate of Federal Polytechnic Nasarawa to the staff quarters are majorly the student of the school, staff of the school and farmers who farm within the school premises.
3.3Â Â Â Â RECONNAISSANCE
Reconnaissance is the first step in any survey work it is the process by which the surveyor goes to study the nature of the terrain before selection of any equipment. Reconnaissance involve walking from whole to part, visiting the project site, clearing obstacle and selecting point or making survey marks on the ground surface intervisibility between the point selected. The final selected points are done during the field reconnaissance survey to suit the field condition for the observations. This project reconnaissance was carried out by visiting the project site thereby bringing out the recce diagram of all the information on the site.
A good field reconnaissance would produce a good survey result.
3.4Â Â Â Â ROUTE MAPPING
Route mapping can be defined as the survey that have to do with the course that is highways road or utility line follows while at the end product from a utility line. It may also be said that the purpose of route survey are
1)Â Â Â Â Â To gather enough information about a particular route to make it possible for designers to select the final route.
2)Â Â Â Â Â To select general route for the road way of utility
3)Â Â Â Â Â also facilitate of work of survey and engineers
3.5Â Â Â Â TRAVERSING
Traversing is one of the most basic and widely practiced means of determining the relative location of points. A traverse is a series of connected lines whose length and direction are determined from field observations.
TYPES OF TRAVERSING
1.    Close traversing
2.    Open traversing
CLOSE TRAVERSING
This is the type of traverse that started from a known co-ordinated station and closes back on the same starting station or on another station whose co-ordinates are known.Â
