  11. The students should submit a report work on the construction materials, covering water proofing material, cements, steel, paints and timber products available in the local market. They will also show the competitive study based upon the cost, brand name, sizes available in the local market.

Surveying- I

Chain surveying:

Ranging a line

Chaining a line and recording in the field book

Taking offsets – perpendicular and oblique (with a tape only)

Setting out right angle with a tape

Chaining of a line involving reciprocal ranging

Chaining a line involving obstacles to ranging

Chain Survey of a small area.

 Compass Surveying:

Study of prismatic compass

Setting the compass and taking observations

Measuring angles between the lines meeting at a point
