3.5 Construction Tech and Env Flashcards
What are the benefits of off-site construction?
-Safety
-Efficiency
-Sustainability
-Speed
-Quality
What should you consider before excavation?
-Depth of excavation
-Nature of soil
-Proximity to buildings
-Underground services
-Water table
Techniques of waterproofing a basement?
Tanking - using materials such as asphalt, polythene sheeting, bitumen…
Drained cavity - create a cavity wall with drainage in-between to remove the water that seeps.
What are SUDS?
Sustainable Urban Drainage Systems - help reduce the reliance on existing drainage infrastructure:
-Filter drain
-Rain water harvesting
-Swale
-Green roof
-Permeable pavement
Typical road build-up?
Wearing/ surface - 20-40mm
Binder - 50-100mm
Base - 70-150mm
Subbase/type 1 - 100-250mm
Typical footpath build-up?
Similar to road build-up but sometimes you don’t need base course.
What should be considered when selecting foundations?
-The load of the building.
-Nature of the ground.
-Type of structure
-Cost.
-Construction constraints (proximity to adjacent buildings).
What are the different foundation types?
Strip foundations - typically used for masonry linear.
Pad foundations - support columns.
Raft foundations - continuous slab.
Piled foundations - columns into the ground.
What are the types of pile foundations and the construction methods?
Types of piles:
-Friction
-End bearing
-Construction methods:
-Driven
-Bored
What is the standard size of a brick?
215mm x 102.5mm x 65mm
How many standard bricks per m/2?
60
How many concrete standard blocks per m/2?
10
Can you name two different types of brick bond?
English - alternating between head and stretcher each course
Stretcher - stretcher facing half overlapped
What are the main components of concrete?
Cement
Aggregate
Water
What is a culvert?
Tunnel structure that allows water to move from one side to the other of an obstacle.
What site surveys are required for typical construction?
Topo survey
Asbestos
GPR
Drainage CCTV
Flood risk assessment
CBR test
Archaeologist
Name some fire safety provisions for buildings?
Fire alarms
Sprinklers
Compartmentation
Fire Dampers

Fire evacuation plan
Fire extinguisher types?
Water - dry solid materials
Foam - flammable liquids
Dry power - flammable liquids
Co2 - electrical
Wet chemical - cooking oil
What are building regulations and examples of them?
Ensure buildings are safe, healthy and high performing.
-Part L - Conservation of fuel and power
-Part M - Access to and use of buildings
What is an O&M manuals?
Operating and maintenance Manual
Construction tech - Level 2 Example?
Review the pavement schedule and see which areas needed narrow widening.
Construction tech - Level 3 Example?
Advised on the plane and relay and slip trenching around the industrial estate.
What are modern methods of construction with examples?
Innovative ways to build structure. Ways to save time, money, or increase quality.
- Modular building / 3D volumetric construction
- Prefabrication (SIPs)
- Precast concrete
Composite materials in construction?
- Reinforced concrete
- Glulam / plywood
- Reinforced plastics
Ground improvement methods?
- Grouting
- Soil mixing
- Geotextiles
- Soil compaction
What is the ICMS?
Sets international standard for cost management created by the RICS for
- latest edition updates life cycle costing and carbon emissions
What is the IPMS?
International property measurement standard.
At what stage would you appoint your construction team under RIBA stages?
What is the difference between Value Management and Value Engineering?
VE - post design exercise to change to solve a problem.
VM - design stage, comparison of different options to get to the best mix.
