(14 cards)
What role does subsoil play in the behavior of foundations in construction?
Subsoil influences the drainage and stability of the foundation, affecting load distribution
Subsoil provides nutrients for plant growth but is primarily important for foundation integrity.
What is one advantage of using undisturbed soil sampling over disturbed sampling?
It preserves the natural structure and moisture content of the soil
This method provides more accurate data for soil analysis.
What is one advantage and one disadvantage of using trial pits for soil investigations?
Advantage: They provide direct soil observation; Disadvantage: They are time-consuming
Trial pits allow for visual inspection but can delay project timelines.
What are the advantages and disadvantages of using a hand auger for soil sampling?
Advantage: It is portable and inexpensive but limited to shallow depths and hard soils
Hand augers are useful for quick sampling but may not reach deeper soil layers.
How would site analysis data influence design choices for a building in a flood-prone area?
It would inform you to elevate the building and incorporate drainage solutions to mitigate flood risks
Proper site analysis is crucial for ensuring safety and structural integrity.
What are the primary objectives of the Irish building regulations?
To ensure safety, health, and welfare in construction
These regulations also promote sustainable practices in the building industry.
What is the primary purpose of shallow strip foundations in construction?
To distribute building loads to the ground
Shallow strip foundations are essential for load-bearing in low-rise buildings.
What is the definition of loadbearing capacity in relation to construction foundations?
The maximum load a foundation can support without failure
This is a critical factor in ensuring the structural safety of a building.
What is the primary purpose of reinforcement in foundation construction?
To enhance the strength and stability of foundations
Reinforcement helps prevent structural failure under load.
What strategy would be most effective in preventing radon leakage in a new residential building?
Implementing an active radon mitigation system during construction
This is crucial in areas known for high radon levels to ensure indoor air quality.
What is a pad foundation?
A type of foundation that supports a single column or a small area of a structure
Pad foundations are typically used for lighter structures.
What is a pile foundation?
A type of foundation that uses long, slender columns driven into the ground to support a structure
Pile foundations are used when surface soil conditions are inadequate.
What is a raft foundation?
A type of foundation that spreads the load of the building over a large area
Raft foundations are often used in areas with weak soil.
What is a strip foundation?
A type of foundation that consists of a continuous strip of concrete supporting load-bearing walls
Strip foundations are commonly used for low-rise buildings.
