Introduction

Surveying entails the process of precise determination of the terrestrial and three dimensional location of points and the distances and angles linking them. Time and again, these points are utilized to determine land maps and boundaries for ownership (Ghilani & Wolf, 2008). More often than not, surveyors, who carry out the survey work, rely on varied variables of physics, trigonometry, geometry, mathematics, law and engineering. Surveying has and still remains to play a significant role in the growth and development of human ecologies as it is applied in varied forms of construction through plan developments and implementation (Roy, 2004). Presently, surveying is applied in varied industries such as transport industry, communications industry, building and construction, in the field of mapping and in establishing legal boundaries for ownership of land.

In the field of processing, there is a technique called traverse which is used to determine control networks. Traverse networks in surveying are beneficial because they require less inspection and organization, they can alter to any shape and hence, accommodate varied terrains, they require few observations per station, they are free of the strength of figure considerations that occur in triangular systems, scale errors are not enhanced in traverse, swing errors can be minimized by enhancing the distance linking stations and they give more accurate readings than triangulateration (Ghilani & Wolf, 2008). Open or free traverse is a link traverse that encompasses a sequence of connected traverse lines that do not revert to the starting point to form a polygon. They are used to plot a piece of land that can then be utilized to plan a layout or construction(Roy, 2004). Open traverse forms the basis of this study. The outline of the study entails an introduction, appendices which include Appendix A which is the copy of the Survey book, Appendix B which is the WCB calculations, Appendix C which is the Coordinate Calculations and the bibliography.

The main objective of this study is to effectively carry out an open traverse survey to determine the layout of the university layout. Using an already set station exterior the grounds, an arbitrary North was established. Important to note is that the Trimble 5600 total station was used as the instrument in the open traverse survey.

Having set the instrument at Zero, the distances is measured and recorded. Thereafter, the instrument is rotated and the acquired distance and angle computed and documented. All this procedure is repeated to all points on the university building where the coordinates are then analyzed and utilized to plot a layout plan as illustrated in the appendices.

The open traverse Survey Procedure

The open traverse survey begin by setting up the Trimble 5600 total station at N 0° 00’00 at the distance 38.582. The calculations for the distances and the angles is as follows

• Clockwise was to 92° 10’ 57”30.019m
• Clockwise was to 07° 49’ 00”16.274m
• Clockwise was to 126° 04’ 48”21.641m
• Clockwise was to 127° 35’ 38”31.265m
• Clockwise was to 151° 46’ 01”55. 705m
• Clockwise was to147° 13’ 21”41.576m
• Clockwise was to 183° 26’ 18”67.971m

The second set up

• Clockwise set up from 57° 26’ 33”41.923m
• 62° 19’ 10”41. 145
• 63° 53’ 03”36.436M
• 88° 51’ 29”37.656m
• 88° 51’ 29”48.547m
• 93° 23’ 51” 43.757m
• 95° 58 031.448m
• 123° 21’ 05”57.791m
• 125° 26’ 43”98.617m
