The field work in surveying:allows students to handle a range of tools and instrumentsincluding chains, levels, transits, theodolites, electronic distancemeasurements, and total stations, and to learn the measurementtechniques useful in the Civil Engineering practice.

On successful completion of this field work, students should beable to:♦ Illustrate an understanding of accuracy of measurement
required in surveying;♦ Illustrate a skill of the principles and techniques of basic
surveying;♦ Identify suitable equipment required for tasks in basic
surveying;♦ Show how to reduce data obtained from fieldwork to a
useable form;♦ Develop a skill to interpret and analyze the data using
different software;♦ Mastery of skills for using Geographical information
Systems (GIS) software.

Field work AssessmentThe evaluation will consist:
♦ field work reports;
♦ term project;
♦ exams.
This part of the course accounts 30% of the total mark for thecourse.
♦ Students will work in groups
♦ Each and every student is responsible forsubmitting a separate field notes
♦ Term project will be submitted in groups.

Field Notes
♦ Measurements
♦ Sketches
♦ Descriptions
♦ Miscellaneous information
Filed notes are the records of work done in the field.
In practice, these records are kept for later computations inthe office or may be used as evidence in a court of law.
Typically, they contain:
