Sol. City survey → It is carried out to locate the premises, streets, water supply and sanitary system.
Cadastral survey → This survey is used to fixing the boundaries of field or define the property line.
Topographical survey→ This survey is used to know about the topography of area such as man-made features and natural features like rivers, mountains, valley etc.
Sol. In stone masonry, the stones are placed in position such that the natural bedding plane is normal to the direction of pressure they carry. The stone used in stone masonry should be hard, strong and durable.
|Work||Per mason per day work|
|1. RCC work||3m³|
|2. Reinforced brick work||1m³|
|3. Work in foundation with cement concrete/ lime||1.25 m³|
|4. Brick work in foundation and plinth||1.25 m³|
|5. Work in superstructure with cement concrete/lime||1 m³|
Sol. As per IS 456-2000, The minimum grade of concrete used in Reinforced concrete is M20.
Sol. As per IRC 66 : 1976–
The intermediate sight distance = 2 × SSD
SSD = Stopping sight distance
Sol. 1ft³ = 0.0283 m³
1 m³ = 1/0.0283 ft^3
1m³ = 35.335 ft³
2m³ = 2 × 35.315 ft³
▭(2m^3=70.67 ft^3 )
