Vilas Javdekar Developers Senior Estimation Engineer Interview Questions, Process, and Tips

Building constants are important for estimating material quantities and costs.

• Concrete has a density of 2400 kg/m³ and a compressive strength of 20-40 MPa.

• Steel has a density of 7850 kg/m³ and a yield strength of 250-500 MPa.

• Other important constants include thermal expansion coefficients and modulus of elasticity.

• These constants can vary depending on the specific type and grade of material being used.

Columns are vertical members that support the load of the structure while shear walls resist lateral forces.

• Columns are primarily designed to support vertical loads while shear walls are designed to resist lateral forces.

• Shear walls are typically thicker and stiffer than columns to resist lateral loads.

• Columns are spaced apart while shear walls are continuous throughout the height of the building.

• Examples of shear wall...read more

Building perimeter to builtup area ratio is a measure of how compact a building is.

• It is calculated by dividing the perimeter of the building by its built-up area.

• A higher ratio indicates a more compact building.

• This ratio is important in urban planning and zoning regulations.

• For example, a building with a large perimeter and small built-up area may not be allowed in certain areas.

• The ratio can also affect the cost of ...read more

The shear wall cross-sectional area to built-up area ratio is specified in building codes.

• The ratio is typically between 0.05 and 0.10.

• The code requirements vary depending on the seismic zone and building type.

• For example, in seismic zone 4, the ratio for reinforced concrete buildings is 0.10.

• The ratio is important for ensuring the structural integrity of the building during earthquakes.

Rolling margin of steel is the difference between the theoretical weight and the actual weight of a steel plate after rolling.

• Rolling margin is calculated by subtracting the actual weight of the steel plate from the theoretical weight.

• It is important to consider rolling margin when estimating the weight of steel plates for a project.

• Rolling margin can vary depending on the thickness and width of the steel plate.

• For exa...read more
