Preview Questions Civil Engineer | Role Specific Skill

Question 1: What is the primary function of fly ash as a supplementary cementitious material in concrete?

Which action should you take?

Choose only one option

Fly ash increases the water-cement ratio, making concrete more porous

Fly ash is used to enhance the aesthetic color of concrete without affecting strength

Fly ash only improves the bonding of cement to aggregates, not the overall strength

Fly ash improves the workability and durability of concrete, while reducing its carbon footprint

Question 2: What material is most commonly used for "temporary formwork" in concrete construction?

Which action should you take?

Choose only one option

Plywood or steel panels, as they are strong, flexible, and reusable

Brick and mortar for more stable forms

Pre-cast concrete for permanent structures

Plastic sheets, for quick and inexpensive molding

Question 3: How does lateral-torsional buckling affect the design of structural beams in buildings?

Which action should you take?

Choose only one option

Lateral-torsional buckling only affects the appearance of beams, not their load-carrying capacity

Lateral-torsional buckling is irrelevant in beam design for low-rise buildings

Lateral-torsional buckling improves the flexibility of beams, allowing them to absorb more load

Lateral-torsional buckling occurs when beams are subjected to lateral forces causing them to twist and fail, which must be prevented in the design

Question 4: What does "setting out" refer to in the context of site surveying for construction?

Which action should you take?

Choose only one option

Setting out refers to marking the boundaries of the property line

The process of marking points, lines, and levels on the site to guide construction

The process of measuring the area of the site for sale or lease

The process of identifying existing utilities and pipes on-site

Question 5: What should a site supervisor do if they notice a structural element has been installed incorrectly?

Which action should you take?

Choose only one option

Delay the correction until the end of the work day to avoid disruptions

Wait for the engineer to come and assess the situation

Allow the work to proceed, as minor mistakes can be fixed later

Stop the work immediately, assess the issue, and correct the installation as per the design

Question 6: When developing a project schedule, what is the purpose of Critical Path Method (CPM)?

Which action should you take?

Choose only one option

To calculate the project's cost per unit

To identify tasks that cannot be delayed without delaying the project

To determine the maximum allowable project duration

To define the scope of work for each phase
