Example answer:
Designing a retaining wall involves calculating the lateral earth pressure and any surcharge loads acting on it. I then check the wall's stability against overturning, sliding, and bearing capacity failure at the base. Finally, I design the wall's structural elements (stem, base) for bending moments and shear forces and ensure adequate drainage behind the wall to prevent hydrostatic pressure buildup.
16. What is the purpose of steel reinforcement in concrete?
Why you might get asked this:
A fundamental concept in reinforced concrete design. This tests your understanding of composite material behavior.
How to answer:
Explain that concrete is strong in compression but weak in tension. Steel reinforcement (rebar) is added to carry the tensile forces and shear stresses that concrete cannot effectively resist, enabling concrete elements to carry loads they otherwise couldn't.
Example answer:
Steel reinforcement is crucial in concrete because concrete is very strong in compression but has low tensile strength. Steel, being strong in tension, is embedded in the concrete in areas where tensile stresses or shear forces are expected, forming a composite material that can effectively resist all types of forces.
17. Explain the process of surveying.
Why you might get asked this:
Surveying is fundamental to site layout and mapping. This tests your understanding of how physical site data is acquired and used.
How to answer:

22. What steps do you take if concrete testing fails?
Why you might get asked this:
A practical problem-solving scenario. This tests your knowledge of construction procedures and quality control steps.
How to answer:
Explain the procedure: verify testing procedures were correct, check related tests (slump, air content), review placement and curing records, perform non-destructive testing (NDT) like rebound hammer or ultrasonic pulse velocity, consider core sampling for strength verification, and if confirmed failure, propose remedial actions like repair, strengthening, or removal and replacement.
Example answer:
If concrete test results fail, I would first verify the testing procedures and sample handling were correct. I'd review placement and curing records for any anomalies. Next, I'd perform non-destructive tests on the structure for an initial assessment. If needed, I'd request core samples for definitive strength testing. Based on the findings, I'd recommend appropriate remedial actions, which could range from acceptance based on in-situ strength, repair, strengthening, or removal and replacement of the affected concrete.
23. Explain the difference between working stress and limit state methods.
Why you might get asked this:
Tests your fundamental knowledge of design methodologies in structural engineering.
How to answer:
Describe Working Stress Design (WSD) as an older method based on elastic theory, using linear stress-strain relationships and ensuring stresses don't exceed allowable limits under service loads. Describe Limit State Design (LSD) as a more modern method considering various failure modes (limit states) like collapse and serviceability, using partial safety factors for loads and material strengths.
Example answer:
Working Stress Design (WSD) is an older approach that ensures stresses in materials remain within elastic limits under expected service loads using a single Factor of Safety. Limit State Design (LSD), the prevalent modern method, considers different failure modes (limit states) like structural collapse and serviceability issues. It uses partial safety factors on both loads (load factors) and material strengths (material reduction factors) to provide a more probabilistic and potentially economical design.
24. How do you approach risk assessment on a project?
Why you might get asked this:
Risk management is crucial for project success. This tests your proactive approach to identifying and mitigating potential issues.
How to answer:
Describe the process: identifying potential risks (technical, financial, schedule, safety, environmental), analyzing their likelihood and impact, prioritizing risks, developing mitigation strategies, and establishing monitoring and response plans.
Example answer:
My approach to risk assessment involves early identification of potential risks across various categories: technical, schedule, cost, safety, environmental, etc. I analyze the likelihood and potential impact of each risk, then prioritize them. For high-priority risks, I develop mitigation strategies and contingency plans and ensure ongoing monitoring throughout the project lifecycle.
25. What is the significance of bearing capacity of soil?
Why you might get asked this:
Fundamental geotechnical engineering knowledge. This tests your understanding of how soil properties affect foundation design.
How to answer:
Explain that bearing capacity is the maximum average contact pressure between the foundation and the soil that will not cause shear failure in the soil. It's significant because it determines the size and type of foundation required to safely support the structure's loads without excessive settlement or ground failure.
Example answer:
The bearing capacity of soil is the maximum load per unit area that the soil can support without undergoing shear failure. It is fundamentally important because it dictates the type, size, and depth of the foundation needed to safely transfer structural loads to the ground. An inadequate bearing capacity can lead to excessive settlement or catastrophic structural failure.
26. Describe the different types of foundations.
Why you might get asked this:
Tests your knowledge of common structural support systems and when they are used.
How to answer:
Briefly describe shallow foundations (spread footings, strip footings, mat/raft foundations - used when bearing capacity is good near the surface) and deep foundations (piles, piers, caissons - used when shallow soil is weak or loads are very heavy).
Example answer:
Foundations are generally categorized as shallow or deep. Shallow foundations, like spread footings, strip footings, or mat foundations, are used when adequate bearing capacity is available relatively close to the surface. Deep foundations, including piles, piers, and caissons, are necessary when shallow soils are weak or unsuitable, transferring loads to stronger soil or rock strata deeper below.
27. How do you handle changes in project scope?
Why you might get asked this:
Scope creep is a common challenge. This tests your project management skills and ability to manage client expectations and project constraints.
How to answer:
Explain a structured process: documenting the proposed change, assessing its impact on schedule, cost, and technical requirements, obtaining approval from relevant stakeholders, and formally updating project plans and documentation.
Example answer:
Changes in project scope require a formal process. I document the proposed change thoroughly, assess its impact on the project's cost, schedule, technical requirements, and quality. I then communicate this impact to the client and stakeholders for approval. Once approved, I ensure all project plans, documents, and budgets are updated to reflect the change formally.
28. What is BIM and how have you used it?
