- Control line
- Plot line
- Building line (Correct answer)
- Property line
Correct answer: Building line
A building line is a specific boundary established by local authorities, typically parallel to the property lines, beyond which no construction is permitted. Its purpose is to ensure adequate setbacks from roads or adjacent properties, maintain uniform streetscapes, and allow space for utilities. This line dictates the maximum permissible footprint for a structure on a site.
Question 7: Which of the following building materials has a high level of flexibility in nailing joints and seismic resilience.
- Ply
- Timber (Correct answer)
- Bamboo
- Husk
Correct answer: Timber
Timber, being a natural wood product, possesses inherent flexibility and resilience, making it highly suitable for structures that need to withstand dynamic forces like seismic activity. Its fibrous structure allows for strong, flexible connections with nails and other fasteners, enabling it to absorb and dissipate energy effectively. This combination of properties provides excellent seismic resilience and joint flexibility.
Question 8: Construction of cavity walls serves as an external defense against heat or cold since the void between two walls serves as a .
- Insulating material (Correct answer)
- Building material
- Burning material
- Destructive material
Correct answer: Insulating material
Cavity walls are designed with a deliberate air gap between two leaves of masonry. This trapped air acts as an excellent insulating material because air is a poor conductor of heat. Consequently, the void significantly reduces heat transfer through the wall, providing an effective external defense against both heat penetration in warm climates and heat loss in cold climates.
Question 9: Which of the subsequent types of foundation is used while building on soil made of black cotton?
- Floating foundation
- Grillage foundation
- Inverted arch foundation
- Mat foundation (Correct answer)
Correct answer: Mat foundation
Black cotton soil is highly problematic due to its expansive nature, swelling and shrinking significantly with moisture changes, which can cause severe differential settlement. A mat foundation (or raft foundation) covers the entire footprint of the structure, distributing the building's load over a large area. This minimizes localized stress concentrations and reduces the risk of differential settlement, making it ideal for such challenging soil conditions.
Question 10: Which organization sets the requirements for the separation between wall ties installed in cavity walls?
- Building Regulations of U.K. (Correct answer)
- Building Regulations of India
- Building Regulations of China
- Building Regulations of Russia
Correct answer: Building Regulations of U.K.
The Building Regulations of the U.K. provide comprehensive guidelines and requirements for various aspects of building construction, including the specifications for wall ties in cavity walls. These regulations, particularly Approved Document A (Structure), detail the type, spacing, and installation of wall ties to ensure the structural stability and safety of cavity wall construction within the United Kingdom.
Question 11: What sort of masonry is not a composite masonry?
- Brick composite masonry (Correct answer)
- Glass block masonry
- Cement concrete masonry
- Stone composite masonry
Correct answer: Brick composite masonry
Although 'Brick composite masonry' contains the word 'composite,' implying a combination of materials, it is sometimes distinguished from other forms of composite masonry where two *fundamentally different* structural materials (like brick and stone) are explicitly combined. In certain classifications, a wall primarily of bricks, even with variations, might not be categorized as 'composite' in the same distinct structural sense as other options, thus making it the answer for 'not a composite masonry' in that specific context.
Question 12: In construction, demolition, maintenance, or repair projects, a temporary structure known as _________ is helpful.
- Underpinning
- Grouting
- Scaffolding (Correct answer)
- Shoring
Correct answer: Scaffolding
Scaffolding is a temporary elevated structure erected to provide a safe and stable working platform for workers and to support materials during construction, demolition, maintenance, or repair projects. Its primary function is to facilitate access to various parts of a structure at height, ensuring safety and efficiency in the work process.
Question 13: Which of the following building materials was used in the past to construct superstructures?
- Mud
- Rubber
- Timber (Correct answer)
- Bamboo
Correct answer: Timber
Timber has been a historically significant and widely used building material for superstructures for thousands of years. Its strength-to-weight ratio, availability, and ease of fabrication made it a primary choice for framing, roofs, and entire buildings before the widespread adoption of steel and concrete. While other materials like mud and bamboo were also used, timber offered superior structural capabilities for larger constructions.
Question 14: Which of the following is specified at the top of the structure and is built in the shape of a framework to protect the building from weather conditions like rain, heat, snow, wind, etc.?
- Truss
- Chajja
- Roof (Correct answer)

Correct answer: Roof
The roof is the uppermost part of a building, specifically designed as a framework to protect the structure from all external weather conditions. It shields the interior from rain, snow, heat, wind, and other environmental elements. Its primary function is to provide shelter and contribute significantly to the building's overall integrity and thermal performance.
Question 15: Which of the following risks involves the demolition or damage to the building itself?
- Internal hazard (Correct answer)
- Building hazard
- Personal hazard
- Surrounding hazard
Correct answer: Internal hazard
An internal hazard refers to risks or dangers that originate within the building itself, leading to potential damage or demolition of the structure. These hazards can include structural failures, material degradation, or issues arising from the building's internal systems or design. It distinguishes problems stemming from within the building's own fabric from external or environmental threats.
Question 16: It becomes necessary to supply the ________ structure when the area to be contained is huge in order to give the cofferdam solidity.
- Double wall cofferdam (Correct answer)
- Suspended cofferdam
- Single wall cofferdam
- Cellular cofferdam
Correct answer: Double wall cofferdam
When a large area needs to be enclosed for construction work within water, a double-wall cofferdam is often employed. This type consists of two parallel rows of sheet piles driven into the ground, with the space between them filled with granular material. This design provides significantly enhanced stability and rigidity, making it suitable for larger and deeper excavations compared to single-wall cofferdams.
