GRID LEVELING AND CONTOURING OF PART OF KOGI STATE POLYTECHNIC, MAIN CAMPUS LOKOJA KOGI STATE

ABSTRACT

Surveying is a science of making precise measurement of relative position of points and features sizes, shape and position of piece of land and present its physical on paper inform of a map; plan or section. The project grid leveling and contouring which is used to determine the spot height, contour and horizontal of position point in part of Kogi State Polytechnic, Main Campus Lokoja which was jointly executed in conformity with the school of Environmental Technology. The work was achieved by carrying out the following: (i) Coordinate of point (traversing) (ii) Girding (iii) Leveling (iv) Plotting of establish point and spot height. This project involves the use of three method of surveying and these are traversing was used to defined the project area into grid and leveling is to determine, the height of point grid. The project is aimed to provide a contour plan showing the elevation surface and contour of the area of the land cover. Meanwhile contouring is system of representation line on a plan or map joining of points of equal height on the earth surface or intersection of level surface within the area covered. This project report is organized in four chapters, these reports address the various survey method and procedure adopted. Instrument used for the field data, description of problem encountered and recommendation.

CHAPTER ONE

1.0    INTRODUCTION

This project involves traversing to coordinate, the corner points of the project area, girding, leveling and contouring of the same.

1.1    BACKGROUND INFORMATION OF THE STUDY AREA

          The background of study is a section of Kogi State Polytechnic Lokoja which comprises the school of Environmental Technology Lokoja, Department of Computer Science, Rector’s Office, the Chapel and Department of Science and Laboratory Technology (SLT) Kogi State Polytechnic Lokoja, Kogi State.

1.2    STATEMENT OF PROBLEM

Physical developments building structures have been erected without recourse to proper land management practice. No plan of the land available anywhere and no documented information of the nature of terrain.

The project is meant to provide a contour plan which will fill the gap created by this lack of documented information to facilitate intelligent sighting/location of certain physical projects.

1.3    AIMS AND OBJECTIVE

The aim of this project is to produce a plan showing the contours of the area covered.

OBJECTIVE:

1. For the determination of elevation of different point along the alignment of the proposed project.
2. Leveling is used for calculating volume of earthwork, reservoir etc.
3. The contour interpolation is for the determination of the slopeness of the ground of the area covered.

1.4    SCOPE OF STUDY

          The scope of the project-work is to carryout the following:

1. Perimeter survey of the area to determine the extent.
2. Girding the area to 20m intervals
3. Acquiring data on the spot heights
4. Produce a contour plan of the area

1.5    THE PROJECT AREA

The area of project is part of Kogi State Polytechnic Lokoja, which comprises the school of Environmental Technology (SLT), Department of Computer Science and the Chapel.

 1.6    JUSTIFICATION

A contour plan of part of Kogi State Polytechnic, main campus Lokoja is not only important for reference and achieving purposes but also for proper maintenance restructuring administrative utilization and future development.
