1. (a) Give classification of stone masonory. What points should the observed while supervising stone masonary work?
(b) Define a linted. Mention where and why they are used in buildings. provide name of molenals which are commonly made for making lintel?
(c) What are different kinds of stairs cases commaonly used? Which of the kinds you will use when.
(i) Space available is minimum.
(ii) Space available is large.
2. (a) What are different kinds of cement commonly available? provide details of any 4 kinds of cement.
(b) What is water cement ration? How is it important for the strength of concrete?
(c) Write down advantages of prestressed concrete over other low kinds of concrete available.
3. (a) Explain the different obstacles encountered during chain survey. How are they tackled?
(b) A distance of 4666 m was measured by a 30 m chain. Later it was detected that chain was obtained 2.5 cms too long. If the chain was initially correct, determine the exact length that was measured.
(c) Discuss only disadvantages of Plane table surveying?
4. (a) Define the subsequent terms :
(i) True meridian
(ii) Magnetic meridian
(iii) Magnetic declination
(iv) Local attraction.
(b) Following observations were made with a compass. At what stations do you suspect local attraction? obtain the corrected bearings of the lines:
Line Fore Bearing Back Bearing
AB S 45 degree 30' E N 45 degree 30' W
BC S 60 degree 00' E N 60 degree -40' W
CD S 03 degree 20' E N 05 degree -30' W
DA S 85 degree 00' W N 83 degree 30' E
(c) Differentiate ranging from fore bearing and back bearing?
5. The subsequent consecutive readings were taken on a ground.
Instrument was shifted after fifth & eighth studying now.
Stations B.S. I.S. F.S. H.I. R.L.
A 0.165 100.165 100.00 B.M.
B 2.100 98.065

H 3.085 95.32
I 2.125 96.28
The instrument was shifted after taking fifth and eighth readings. Enter the data in a level book page and compute all the R.L.S., if 1st studying was taken on B.M. 100.00. Apply usual check.
