Construction Technology Flashcards
(14 cards)
What are Building Regulations
- Regulations to ensure building works are safe, healthy and high performing
- Approved Documents
What are British Standards
Recommend minimum standards for materials, components, design and construction practises
Major advancements being used in construction
- Modular builds
- LiDAR (Laser based technology - distance and 3D imaging)
- 3D Printing
- VR (Remote site inspections)
- AI (Decision making, identify risks)
+/- Off site construction
- Quality control - Components produced in controlled environment
- Speed - Works in factory can happen in tandem to works on site
- Reduced on site work - Less disruption
- Safety - Reduce risk of on site accidents
CONS - Transportation costs - Costs associated with transporting large components
- Limited customisation - Less flexibility to make changes once on site
- Site constraints - Large components may be difficult to manouver
How did you compare the programme implications of the different options
- Comparing the three options
- Looked at decant
- Lead times (procurement of materials)
- Using steel frame instead of concrete
What makes up a built up cladding system
- Interior finish
- Steel frame system
- Insulation
- Vapour barrier
- Air gap
- Fixing system (to attach stone panels to)
- Stone panels
Types of Pile foundations
- A pile is a column that extends deep into ground
- Where bearing capacity of soil is poor
- Two main types of pile
- End bearing piles
- Friction piles
- Two main construction methods
- Bored piles (Steel cage - Poured)
- Driven piles (Impact, vibration, pressing)
How to build a steel frame
- Prep site
- Base plates on foundation
- Erect steel columns
- Install beams
- Add bracing
Brick Blockwork walls
Block
Insulation
Cavity
Brick
(Wall ties)
+/- In situ construction
- Customisation - Can adapt on site
- Durability - Works can be tailored to environment
CONS - Weather - Can be delayed due to weather
- Quality control - More challenging to maintain consistent quality on site
- Labour intensive - Requires more labour
Different roof coverings
Slate - Long life span
Clay tiles - Aesthetics
Asphalt shingles - Popular
Green roof- Environmentally friendly
Bitumen
Components of roof
Wall plate - sits above wall which rafts fasten to
Rafters - Angled board rests on wall plate, connects to ridge board
Ridge board - Runs along peak of roof
Joists - Spans roof, wall plate to wall plate
Why use lead lined walls in the MRI room
- Material is more dense
- Create barrier to stop radiation passing through
- Maintained by Bristish standards
When might modular builds not be suitable
- Refurbishment projects
- Complex projects that do not have repeating layouts
