Signature Global Senior Civil Engineer Interview Questions and Answers

The cable size required for a 10 hp motor depends on the voltage and current rating of the motor.

• The cable size should be selected based on the motor's full load current (FLC) and the voltage rating.

• For a 10 hp motor, the FLC would typically be around 15-20 Amps.

• A common cable size for a 10 hp motor operating at 415V could be 4 sq mm cable.

The quantity of cement in M25 grade concrete is 350 kg/m³.

• M25 grade concrete has a mix proportion of 1:1:2 (cement:sand:aggregate).

• The total volume of concrete is taken as 1 m³.

• Therefore, the quantity of cement required for 1 m³ of M25 grade concrete is 350 kg.

• This is calculated by multiplying the volume of concrete by the proportion of cement in the mix.

The weight of steel varies with its diameter.

• The weight of steel can be calculated using the formula: weight = volume x density

• The density of steel is approximately 7850 kg/m³

• The volume of steel can be calculated using the formula: volume = pi x (diameter/2)² x length

• For example, a 10mm diameter steel rod with a length of 1 meter would weigh approximately 0.393 kg

Waterproofing is the process of making a structure or object resistant to water penetration.

• Identify the areas that need waterproofing such as roofs, walls, and foundations.

• Clean and prepare the surface to be waterproofed.

• Apply a waterproofing membrane or coating such as bituminous, acrylic, or polyurethane.

• Ensure proper drainage and slope to prevent water accumulation.

• Test the waterproofing system for leaks and make n...read more
