Rohan Builders Civil Engineer Interview Questions and Answers

Testing pressure in plumbing systems ensures safety and functionality by identifying leaks and verifying system integrity.

• 1. Visual Inspection: Check for visible leaks or damage in pipes and fittings.

• 2. Pressure Testing: Use a pressure gauge to measure the system's pressure, ensuring it meets specified standards.

• 3. Hydrostatic Testing: Fill the system with water and pressurize it to check for leaks over a specified dur...read more

A single flat typically has several snag points that need to be addressed for safety and functionality before occupancy.

• Structural Issues: Cracks in walls or ceilings can indicate underlying structural problems that need to be fixed.

• Plumbing Leaks: Check for leaks under sinks or around toilets, which can lead to water damage if not addressed.

• Electrical Faults: Ensure all outlets and switches are functioning properly to...read more

Vertical column stirrups typically have two bends to provide adequate support and confinement for the concrete.

• Stirrups are usually made of steel bars bent into a U-shape.

• Each stirrup typically has two bends at the ends to secure it to the main reinforcement.

• The number of bends can vary based on design requirements, but two is standard for vertical columns.

• For example, in a rectangular column, stirrups are placed at re...read more

A shunt relay in an ACB is used to provide protection against overcurrents by diverting excess current away from the main circuit.

• Shunt relay is connected in parallel with the main circuit of the ACB.

• It detects overcurrents and activates to divert the excess current through a shunt path.

• This helps in protecting the main circuit from damage due to overcurrents.

• Shunt relays are commonly used in Air Circuit Breakers (ACBs...read more

CoC in HVAC stands for Certificate of Conformance, which is a document certifying that a product meets specified requirements.

• CoC in HVAC is a Certificate of Conformance that ensures a product meets specific requirements.

• It is often required in HVAC projects to ensure quality and compliance.

• CoC may include details such as product specifications, testing results, and manufacturer information.

Biological oxygen demand (BOD) and Chemical oxygen demand (COD) are important parameters in wastewater treatment plants.

• Biological oxygen demand (BOD) is a measure of the amount of dissolved oxygen needed by aerobic biological organisms to break down organic material in water.

• Carbonaceous oxygen demand (COD) is a measure of the amount of oxygen required to oxidize all the organic and inorganic matter in water.

• BOD is a ...read more

A voltage monitoring relay is a device that monitors voltage levels and triggers an alarm or protective action if the voltage exceeds or falls below a set threshold.

• Monitors voltage levels in electrical systems

• Triggers alarm or protective action if voltage exceeds or falls below set threshold

• Used to protect equipment from damage due to voltage fluctuations

WTP plant works on the principle of physical and chemical processes to remove impurities from water.

• Water enters the plant and goes through processes like coagulation, flocculation, sedimentation, filtration, and disinfection.

• Coagulation involves adding chemicals to water to make impurities clump together.

• Flocculation helps in forming larger particles called floc for easier removal.

• Sedimentation allows the floc to sett...read more

I provide daily and monthly reports on project progress, issues, and key metrics to track performance.

• Daily reports include updates on tasks completed, challenges faced, and plans for the next day.

• Monthly reports summarize overall progress, budget status, and any potential risks or delays.

• Reports may also include key performance indicators (KPIs) such as project milestones achieved, budget variance, and resource utiliz...read more
