(SEM III) THEORY EXAMINATION 2017-18 SURVEYING

This document contains the complete B.Tech (Semester III) Theory Examination 2017–18 question paper for the subject Surveying (RCE-302). The paper spans two printed pages, carries a total of 70 marks, and evaluates a student’s understanding of surveying principles, instruments, leveling, traversing, contouring, curve setting, and practical field applications.
 

Section A – Short Conceptual Questions (14 Marks)

Section A includes seven brief questions testing the student's basic knowledge of fundamental surveying terms and tools. Concepts include:

Initial and final sub-chords in curve setting

Meaning of a 12 cm compass

Interpretation when contour lines cross each other

Method of folding and unfolding a chain

Definition of normal tension

Purpose of an index sketch

Meaning of azimuth

These questions examine the essential theoretical foundation needed for practical surveying.
 

Section B – Analytical & Field-Based Questions (21 Marks)

Students must attempt any three out of five in-depth questions. These require procedural knowledge, numerical computation, and application of field methods:

Classification of surveying based on instruments used, and listing of equipment for a chosen method

Surveying details by offsets from survey lines, merits of different offsets, and why short offsets are preferable

A complete level book problem involving:

Rise and fall/RL calculations for nine staff readings

Finding RL of a ceiling using inverted staff

Determining staff readings on pegs to achieve a gradient of 1 in 100

Meaning of shift, and proving geometric properties of a transition curve

Purpose of providing a curve, with derivation of the equation of an ideal transition curve

This section tests computational accuracy and mastery of standard field procedures used in civil engineering.
 

Section C – Long Questions (35 Marks)

Students must attempt one part from each of the five questions. These questions involve advanced concepts, corrections, and practical design:

Q3 – Tape Corrections / Error Sources

Applying correction for temperature, tension, sag, and other parameters for a 30-m steel tape used at different conditions

Sources of errors in chaining and precautions to minimize them

Q4 – Traverse Adjustment / Local Attraction

Detecting and correcting fore and back bearings for local attraction

Meaning of balancing a traverse, with three adjustment methods

Q5 – Orientation & Contouring

Meaning of orientation and its methods with sketches

Definition, characteristics, and uses of contour maps

Q6 – Traversing & Bubble Tube Sensitiveness

Meaning and determination of bubble sensitiveness

Meaning of traversing and describing its various methods

Q7 – Transition & Circular Curves

Designing a circular curve with given speed, centrifugal ratio, and rate of change of radial acceleration

Necessity of transition curves and methods of finding their length

This section evaluates a student’s ability to apply surveying theory in real-world engineering design and field problems.
 

Summary

The Surveying (RCE-302) exam paper thoroughly assesses student competency in:

Basic surveying instruments and terms

Leveling and RL computation

Offsets, traversing, and chain surveying

Contouring and map interpretation

Transition and circular curve design

Local attraction correction

Tape corrections and error minimization

It is a complete academic resource for students studying civil engineering surveying principles and field practices.
