GMR Group Quantity Surveyor Interview: Rounds, Questions and Preparation

What the job involves

A Quantity Surveyor in real estate and infrastructure prepares cost estimates, bills of quantities, and tender documents, then manages contracts and payments through construction. Day to day involves measuring work, valuing variations, certifying contractor bills, and tracking project costs against budgets. At large infrastructure firms, they work on highways, airports, metro, and buildings, ensuring projects stay financially controlled from design to handover.

Role and Technical Knowledge

1. 1

   What is the difference between a bill of quantities and a bill of materials?

   Explain that BoQ lists items with quantities and rates for tendering, while BoM lists materials needed for construction without rates. Highlight BoQ's role in contract payment.

2. 2

   How do you calculate the quantity of concrete for a footing?

   Show step-by-step: volume = length x width x depth, accounting for any deductions. Mention using IS 1200 measurement rules and adding wastage percentage.

3. 3

   What is rate analysis and why is it important?

   Define it as determining cost per unit of work, including materials, labour, plant, overheads, and profit. Explain its use in preparing estimates and verifying contractor rates.

4. 4

   What are the different types of contracts used in infrastructure projects?

   Cover item rate, lump sum, cost plus, EPC, and turnkey. Give a brief example of when each is suitable, such as EPC for large highways.

Practical Scenarios

1. 5

   You are given a drawing of a retaining wall. How would you prepare a quantity takeoff for it?

   Describe breaking the wall into sections (base, stem, counterfort), measuring concrete and reinforcement separately, and using standard measurement rules. Mention checking dimensions from the drawing.

2. 6

   A contractor claims extra payment for additional excavation due to rock. How do you verify the claim?

   Explain checking site records, joint measurements, contract clauses on differing site conditions, and rate analysis for rock excavation. Emphasise documentation and approval process.

3. 7

   How would you handle a situation where actual material consumption exceeds the estimated quantity?

   Discuss investigating causes (wastage, theft, design change), comparing with BoQ, and reporting to project manager. Suggest corrective actions like tighter supervision and re-measurement.

4. 8

   What is a variation order and how do you process one?

   Define variation as a change in scope instructed by the client. Outline steps: identify, measure, price using contract rates or new rates, get approval, and update budget.
