SVR Infra Projects Assistant Project Manager Interview Questions and Answers

Self-defense is the legal right to protect oneself from harm using reasonable force.

• Self-defense laws vary by jurisdiction, but generally allow for reasonable force to prevent harm.

• Examples include using physical force to fend off an attacker or using non-lethal weapons.

• The force used must be proportional to the threat faced; excessive force may lead to legal consequences.

• Self-defense can be claimed in both criminal an...read more

I have knowledge of building execution, bar bending schedule (BBS), and bill of quantities (BOQ) essential for project management.

• Building execution involves overseeing construction activities to ensure they meet design specifications and timelines.

• BBS is a detailed list of the quantity and dimensions of steel reinforcement bars required for a project, crucial for cost estimation.

• BOQ is a document that itemizes materia...read more

Mixing ratios refer to the proportionate relationship between different substances in a mixture.

• Mixing ratios are often expressed as fractions or percentages.

• For example, a 1:3 mixing ratio means one part of substance A to three parts of substance B.

• In cooking, a mixing ratio of 2:1 for oil to vinegar is common for salad dressings.

• In construction, a concrete mixing ratio might be 1:2:3 for cement, sand, and gravel.

Concrete grades indicate the strength and composition of concrete, essential for construction durability and safety.

• Grade designations are based on compressive strength, e.g., M20, M25, M30.

• M20 concrete has a compressive strength of 20 MPa, suitable for residential buildings.

• M25 is often used for medium-strength structures like pavements.

• Higher grades like M40 and M50 are used in high-rise buildings and bridges.

The cement garden refers to a construction technique involving curing cement for optimal strength and durability.

• Curing cement typically takes about 28 days for full strength.

• Initial setting time for cement is usually 30 minutes to 2 hours.

• Curing methods include water curing, covering with wet burlap, or using curing compounds.

• Example: In hot weather, curing may require more frequent watering to prevent rapid drying.

Concrete setting times are crucial for determining workability and strength development during construction.

• Initial setting time: The period after mixing when concrete begins to harden, typically 30 minutes to 2 hours.

• Final setting time: The time when concrete has fully hardened and can bear weight, usually 4 to 8 hours.

• Factors affecting setting times include temperature, humidity, and the type of cement used.

• For examp...read more

The weight of a 25 mm diameter steel bar can be calculated using its density and volume.

• Steel density is approximately 7850 kg/m³.

• The volume of a cylinder (steel bar) is calculated using the formula: V = πr²h.

• For a 25 mm diameter bar, the radius is 12.5 mm or 0.0125 m.

• If the length of the bar is 1 meter, the volume would be: V = π(0.0125)²(1) ≈ 0.0004909 m³.

• Weight can be calculated as: Weight = Volume × Density = 0.000...read more

Density varies among construction materials: cement, bricks, wood, and steel have distinct densities impacting their use in projects.

• Cement: Approximately 1440 kg/m³; used in concrete and mortar.

• Bricks: Typically around 1600-1900 kg/m³; common in walls and structures.

• Wood: Varies widely; softwoods like pine ~500 kg/m³, hardwoods like oak ~700-900 kg/m³.

• Steel: About 7850 kg/m³; essential for structural frameworks and re...read more

Testing bricks involves assessing their strength, durability, and quality through various methods and standards.

• Visual Inspection: Check for cracks, chips, or irregular shapes.

• Water Absorption Test: Submerge the brick in water for 24 hours to measure absorption rate.

• Compressive Strength Test: Use a testing machine to apply pressure until the brick fails, measuring its strength.

• Efflorescence Test: Check for white powder...read more

Limit states in structural engineering define conditions under which a structure may fail or become unserviceable.

• Ultimate Limit State (ULS): Ensures safety against collapse; e.g., a bridge must support maximum expected loads.

• Serviceability Limit State (SLS): Ensures comfort and usability; e.g., deflection limits to prevent excessive sagging in floors.

• Fatigue Limit State: Addresses failure due to repeated loading; e.g....read more
