NCCCL Civil Site Engineer Interview Questions and Answers

A structure is a system or arrangement of parts that are interconnected and function together to support loads and resist forces.

• Structures can be man-made or natural

• They can be made of various materials such as steel, concrete, wood, etc.

• Examples include buildings, bridges, dams, towers, etc.

Types of concrete include ready-mix concrete, precast concrete, reinforced concrete, and shotcrete.

• Ready-mix concrete is produced in a batching plant and delivered to the construction site in a plastic condition.

• Precast concrete is cast in a reusable mold or form and cured in a controlled environment before being transported to the construction site.

• Reinforced concrete contains steel reinforcement bars to increase its ...read more

Grades of concrete refer to the strength of the concrete mix design.

• Grades of concrete are denoted by M10, M15, M20, etc. where 'M' stands for mix and the number denotes the compressive strength in MPa.

• Higher grade concrete has higher compressive strength and is used for structural purposes.

• Common grades include M25, M30, M35, and M40 for heavy-duty structures.

• The mix proportions vary for different grades of concrete t

The ratio of M25 grade concrete is 1:1:2.

• The ratio of M25 grade concrete is 1 part cement, 1 part sand, and 2 parts aggregate.

• This ratio is commonly used in construction for various applications.

• For example, if you need to make 1 cubic meter of M25 grade concrete, you would need 1/4 cubic meter of cement, 1/4 cubic meter of sand, and 1/2 cubic meter of aggregate.

Branding schedule is a plan outlining the timeline and activities for promoting a brand.

• Branding schedule includes tasks such as creating a brand strategy, designing a logo, developing marketing materials, and planning advertising campaigns.

• It helps ensure consistency in brand messaging and image across different platforms and channels.

• Example: A branding schedule for a new product launch may include market research, l...read more

Concrete grade and mixing ratio are crucial factors in determining the strength and durability of a structure.

• Concrete grade refers to the strength of the concrete mix, typically denoted by a number like M20, M30, etc.

• Mixing ratio is the proportion of cement, sand, and aggregate in the concrete mix, usually expressed as 1:x:y.

• For example, a common mixing ratio for M20 grade concrete is 1:1.5:3, which means 1 part cemen

Regularly inspect and maintain all equipment and tools used on site to ensure they are in good working condition.

• Create a maintenance schedule for all equipment and tools used on site.

• Check for any signs of wear and tear on equipment and tools.

• Clean and lubricate equipment regularly to prevent rust and corrosion.

• Replace any damaged or worn out parts immediately.

• Train site workers on proper handling and maintenance of e...read more
