Rassaz International School Interview Questions and Answers

Steel quantity can be calculated by multiplying the volume of steel by its density.

• Calculate the volume of steel required for the project

• Determine the density of the specific type of steel being used

• Multiply the volume by the density to obtain the steel quantity

• Consider any wastage or additional steel required for reinforcement

• Example: To calculate steel quantity for a column, multiply the cross-sectional area of the column by its height and the density of steel

To check column beam reinforcement and slab design on site, follow these steps:

• Review the structural drawings and specifications to understand the design requirements

• Inspect the reinforcement bars for proper placement, size, and spacing

• Check the concrete cover thickness to ensure it meets the design requirements

• Verify the alignment and verticality of columns and beams using plumb bobs or laser levels

• Measure the dimensions of the slab to confirm it matches the design

• Check for ...read more

The unit weight of steel refers to the weight of a specific volume of steel material.

• Unit weight of steel is typically measured in kilograms per cubic meter (kg/m³).

• The unit weight of steel can vary depending on the type and grade of steel.

• For example, the unit weight of mild steel is around 7850 kg/m³.

• Higher strength steels like stainless steel can have a higher unit weight.

• Unit weight is an important factor in structural engineering calculations.

Slab details refer to the specifications and characteristics of a concrete slab used in construction.

• Slab details include the thickness, reinforcement, and type of slab.

• The thickness of a slab depends on the load it needs to support.

• Reinforcement in slabs is typically provided using steel bars or mesh.

• Different types of slabs include one-way slab, two-way slab, flat slab, etc.

• Slab details also include the finishing material to be used on the top surface.

Checklist for starting excavation work

• Obtain necessary permits and approvals

• Ensure proper marking and surveying of excavation area

• Identify and mark underground utilities

• Ensure proper safety measures are in place

• Inspect excavation equipment and tools

• Ensure proper disposal of excavated materials

• Monitor weather conditions

• Ensure proper communication and coordination with stakeholders

SBC stands for Standard Building Code.

• SBC stands for Standard Building Code.

• It is a set of regulations and guidelines for construction and building safety.

• SBC helps ensure that buildings are constructed in a safe and structurally sound manner.

Power factor of an alternator is a measure of how effectively it converts mechanical power into electrical power.

• Power factor is the cosine of the angle between the voltage and current waveforms in an AC circuit.

• It indicates the phase difference between voltage and current and ranges from 0 to 1.

• A power factor of 1 means the alternator is operating at maximum efficiency.

• A lagging power factor (less than 1) indicates the presence of reactive power, which can cause inefficienci...read more

Density of concrete is the mass per unit volume of concrete.

• Density of normal concrete ranges from 2200 to 2500 kg/m^3

• Lightweight concrete has a density of 800 to 2000 kg/m^3

• Factors affecting density include type of aggregates, water-cement ratio, and air content
