Height of instrument is the vertical distance between the instrument and a reference point on the ground.
It is used in surveying to determine the elevation of points on the ground.
It is measured using a leveling instrument such as a level or a theodolite.
The height of instrument is calculated by subtracting the height of the reference point from the height of the instrument.
It is important to maintain a consistent heig...
The size of spacer bar depends on the size of the conductor and the voltage rating of the line.
The size of the spacer bar should be such that it maintains the required distance between the conductors.
The size of the spacer bar should be selected based on the voltage rating of the line.
The size of the spacer bar should be selected based on the size of the conductor.
The size of the spacer bar should be such that it can w...

Road construction involves several steps including planning, designing, clearing the land, laying the foundation, paving, and adding finishing touches.
Planning: Determine the route, traffic flow, and necessary permits.
Designing: Create detailed plans including width, materials, and drainage systems.
Clearing the land: Remove trees, rocks, and other obstacles.
Laying the foundation: Level the ground, add layers of gravel ...
Sub grade to wearing course technical specifications include material type, thickness, compaction requirements, and drainage considerations.
Material type for sub grade can be natural soil, stabilized soil, or aggregate base.
Thickness of sub grade is typically specified based on soil conditions and traffic loads.
Compaction requirements ensure proper density and strength of the sub grade.
Wearing course materials can incl...

I applied via Walk-in and was interviewed in Mar 2021. There was 1 interview round.
Only 1 set of cube sample is taken at a casting of concrete of 5 or less than 5 Meter cube to save cost and time.
Taking multiple samples would increase the cost of testing.
The strength of concrete is usually consistent within a small volume.
ASTM C31 allows for only 1 set of samples for small volume concrete.
If the first set of samples fails, additional samples can be taken for verification.
Slump for casting of concrete is measured using a cone. Slump value may decrease as height increases in high rise buildings.
Slump is measured using a cone and the difference between the height of the cone and the height of the concrete after it settles is the slump value.
As height increases in high rise buildings, the pressure on the concrete increases, which may cause the slump value to decrease.
To maintain the desire...
The right bonding agent for recasting of concrete after rain would be a polymer-modified cementitious bonding agent.
The surface should be cleaned and dried before applying the bonding agent.
The bonding agent should be applied in a thin layer using a brush or roller.
The recasting of concrete should be done within the specified time frame mentioned by the bonding agent manufacturer.
Examples of polymer-modified cementitio...
Shear force is the force perpendicular to the beam and bending moment is the torque that causes bending of the beam.
Shear force is calculated by finding the algebraic sum of all the forces acting on one side of the beam.
Bending moment is calculated by finding the algebraic sum of all the moments acting on one side of the beam.
Shear force and bending moment diagrams are used to visualize the distribution of these forces...
CMDI and HDPE are two different types of plastic materials used in various applications.
CMDI stands for Chlorinated Polyethylene Modified Polyethylene and is a thermoplastic elastomer used in wire and cable insulation, automotive parts, and roofing membranes.
HDPE stands for High-Density Polyethylene and is a thermoplastic polymer used in packaging, pipes, and construction materials.
CMDI has better resistance to chemica...
