Construction Technology and Environmental Services Flashcards
What are the various types of foundations you are aware of?
Traditional Strip foundation
Trench fill foundation
Raft Foundations
Pile foundation
Pad Foundations
What are the advantages of traditional strip foundation
- It is less expensive than other types of foundation, such as a deep foundation.
- Strip footing is also quick in construction.
- Simple construction
What are the disadvantages of traditional strip foundation?
- Strip Footing is not as strong as other types.
- It is not suitable for tall buildings.
- Not suitable for weak ground conditions.
What are the advantages of raft foundations
- Raft foundations are constructed for shallow depths hence, it requires less excavation.
- Well suitable in soils of low bearing capacity.
- Loads coming from superstructure are distributed over a larger area.
- Differential settlement of soil can be reduced
What are the disadvantages of raft foundations
- In some cases, large amount of reinforcement is required for raft foundation which increases the cost of project.
- Special attention on raft foundations is required in case of concentrated loads.
- If they are not treated properly, there is a chance of edge erosion.
- Skilled workers are required to construct the raft foundations.
What are the types of pile foundations that you are aware of?
- Bored pile foundation
- Driven t pile foundations
- Sheet Piles
- Secent Piles
What are the advantages of pile foundation?
- High load bearing capacity
- Pile foundations can be adapted to different types of soil, including cohesive, non-cohesive, and mixed soils, allowing for flexibility in construction projects.
- Pile foundations are used for various types of structures.
- Pile foundations are particularly useful in areas with weak or unstable upper soil layers
What are the disadvantages of piles?
- Pile foundations can be more expensive compared to shallow foundations
- Complex Design and Installation: Designing and installing pile foundations require expertise and engineering knowledge
- Pile installation can generate noise and vibrations, potentially causing disturbances to nearby structures
- Pile foundations may not be suitable for sites with limited access to installation equipment.
Tell me about the different types of external wall systems?
- Cavity wall
- External cladding
- Curtain Wall
- Solid Wall
Can you tell me more about curtain walling
- It’s an exterior glazing system that cover the external facade of the building
- Non structural
- Typically comprises glazed or opaque infill panels fixed on to a lightweight aluminium frame lightweight aluminium frame
What are the different kinds of cladding systems you are aware of?
- Brickslip cladding
- Timber cladding
- Aluminium cladding
- Perforated cladding
- Zinc cladding
What is cavity wall?
- External wall which consist of a outer brickwork skin, insulation, a cavity and an brick/blockwork inner skin.
What do you know about timber frame construction
- Uses prefabricated external and internal stud walls, floor joists and roof truss to form the superstructure of the building.
- The timber frame structure can then be clad in brick, wood, fibre cement board, rendered or tiled
On you Heather house project how did you consider Sport England and Rugby Football Union guidelines as part of your design.
The guidelines set out by Sports England and RFU. Set out criteria on the sizes of the changing rooms required and the flooring requirements of the sport hall.
Can you tell me about the different types of soils?
- Sandy Soils
- Clay soils
- Silt Soils
- Peat Soils
