Unit 7 Flashcards
What are two methods of modern wall construction that could prevent moisture ingress?
- Cavity wall construction
- Damp-proof membranes
Cavity walls include an inner and outer layer with an air gap that prevents moisture from penetrating. Damp-proof membranes are barriers that stop moisture from rising through walls.
What building component is shown in the image?
Identify the part shown at point A in the image.
Truss Foundation.
The specific component is not provided in the text.
What is the most appropriate method for securely fixing BSE accessories to plasterboard walls?
Use toggle bolts or specialized plasterboard fixings
Toggle bolts expand behind the plasterboard, providing a strong anchor point for heavy items.
How could a drone be effective for maintaining building service systems on high-rise buildings?
Drones can access difficult-to-reach areas, perform inspections, and provide visual data without scaffolding
This reduces labor costs and enhances safety during maintenance.
What is the most appropriate way to deal with historical wood panelling when installing building services?
Carefully remove the wood panelling and store it for reinstallation
This preserves the historical integrity while allowing necessary installations.
What type of foundation is shown in the image?
narrow strip foundation
The specific foundation type is not provided in the text.
What component is bedded on the mortar joint at point A in the image?
Damp proof course DPC
The specific component at point A is not provided in the text.
Calculate the volume of concrete required for a pile foundation measuring 600 mm in diameter with a depth of 8 m.
Volume = π × (0.3 m)² × 8 m = 2.26 m³
This uses the formula for the volume of a cylinder.
Calculate how many 2440 mm x 1220 mm sheets of plywood are required for shuttering for the inside face of a wall.
Number of sheets = Total area of wall / Area of one sheet
The specific calculations are not provided in the text.
Calculate the total cost for the concrete, excluding VAT.
Total cost = Volume × Cost per cubic metre
The specific calculations are not provided in the text.
Compare the features of two methods of external wall construction.
- Traditional brick wall
- Timber frame wall
Each method has distinct thermal, structural, and aesthetic characteristics.
Describe the difference between the substructure and the superstructure.
Substructure refers to the part of a building below ground level, while superstructure refers to the part above ground level
This distinction is crucial for understanding building design.
What is a substructure in construction?
The part of a building that is below ground level
Examples include foundations and basement walls.
What is infrastructure in construction?
The fundamental facilities and systems serving a country, city, or area
Examples include transportation systems, communication networks, and water supply.
What part of building regulations apply to resistance to the passage of sound?
Approved Document E
This document outlines sound insulation requirements.
