PART – A
Answer all questions.1. Explain the principles of surveying.
2. List out the errors in tape measurement.
3. Sketch a typical page in a levelling field book.
4. Mention the characteristics of contour maps.
5. What is bearning capacity of soil ? How will it affect the selection of foundation ?
6. What is the criteria of selection of roofing materials ?
7. Differentiate between precast and prestressed concrete.
8. Explain any two systems of vertical transportation.
PART – B
MODULE – 1
9. a) What is ranging ? Explain the different methods of ranging.b) To measure a base line, a steel tape 30 m long standardised at 15°C with a pull
of 100 N was used. Find the correction per tape length if the temperature at
the time of measurement was 20°C and the pull exerted was 160 N.
E = 2.1×107 N/cm2, α = 7.1×10–7/°C, wt of 1cm3 of steel = 7.86 gm.
OR
10. a) Explain the significance of Total station and GPS in surveying in the present
context.
b) A series of offsets was taken from a base line to a curved boundary at intervals
of 10 m in the following sequence :
0, 2,68, 3.64, 3.70, 4.60, 3.62, 4.84, 5.74.
Complete the area between the base line, the curved boundary line and the end
offsets using Simpson’s rule and compare the results with trapezoidal rule.
MODULE – 2
11. a) What are the criteria for selection of site for buildings ?b) Draw neat sketches of a spread footing, isolated footing, and Mat foundation.
OR
12. a) Name the different types of stone measoury with sketches.b) What is plastering ? Explain the procedure for the same.
MODULE – 3
13. a) Enumerate the IS specifications for the different tests on cement.b) How is plain cement concrete mixture proportioned and prepared ?
OR
