HCC Infrastructure Contract Engineer Interview Questions and Answers

There are various types of structures, including buildings, bridges, dams, tunnels, and towers.

• Structures can be classified based on their purpose, design, and materials used.

• Buildings can be further classified into residential, commercial, and industrial structures.

• Bridges can be classified into beam, arch, suspension, and cable-stayed bridges.

• Dams can be classified into gravity, arch, buttress, and embankment dams.

Density is the measure of mass per unit volume of a substance.

• It is a physical property of matter.

• It is calculated by dividing the mass of a substance by its volume.

• Units of density include kg/m³, g/cm³, and lb/ft³.

• Density can be used to identify substances and determine their purity.

• For example, gold has a density of 19.3 g/cm³, while aluminum has a density of 2.7 g/cm³.

There are two types of density construction: compacted and loose.

• Compacted density construction involves compressing the material to increase its density, such as in road construction.

• Loose density construction involves leaving the material in its natural state, such as in landscaping.

• The type of density construction used depends on the intended use of the material and the desired level of compaction.

• Other factors that...read more

• Visual inspection to check for proper joint alignment and sealant application

• Water tightness test to ensure no water leakage through the joint

• Load transfer test to verify the joint can handle the intended load

• Other tests may include pull-out test, shear test, and compression test

• Testing frequency and methods may vary d...read more

Precommissioning tests of transformers ensure proper functioning and safety before energizing.

• Visual inspection of transformer and its components

• Measurement of insulation resistance

• Measurement of winding resistance

• Verification of transformer ratio and polarity

• Verification of oil level and quality

• Testing of protective devices

• Verification of grounding

• Functional testing of cooling system

• Verification of nameplate data

11kv & 33kv overhead power line distribution

• 11kv and 33kv are common voltage levels for overhead power lines

• Overhead power lines are used to distribute electricity from power stations to consumers

• The voltage level determines the distance the power can be transmitted and the size of the conductors needed

• Proper insulation and grounding is important for safety

• Maintenance and inspection of the lines is necessary to ensure ...read more

The elongation % of steel fy 500 is approximately 12%.

• Elongation % is the measure of ductility of a material.

• It is the percentage increase in length of a material before it fractures under tension.

• For steel fy 500, the elongation % is approximately 12%.

• This means that the steel can stretch up to 12% of its original length before it breaks.
