For all other civil 4th sem bteup diploma syllabus 2017 you can visit Civil 4th Sem BTEUP Diploma Syllabus 2017 Subjects. The detail syllabus for surveying i is as follows.

Rationale:

The important functions of a Civil engineering technician includes the jobs of:

1. Detailed Surveying,
2. Plotting of Survey data,
3. Preparation of Survey maps and setting out works.

While framing the curriculum for the subject of “surveying” stress has been given to the development of the skill in each type of sruvey like chain surveying, compass surveying and levelling – that the Civil Engineering Diploma holder will normally be called upon to perform.
Field work should be so selected that, as far as possible, the student can check his work and have an idea of the results, that is the extent of error in the work done by him. As far as possible, the surveys done should be got plotted, as this will also reveal errors in the work and develop skill in plotting.

DETAILED CONTENTS
