Level 2 Flashcards
What was the build up of the property (Sibley Close)?
1990’s semi-detached property- two storey, cavity wall construction with solid concrete floor and suspended timber first floor.
What era was this from and how could you tell?
Cavity wall construction, relatively good condition of building elements, UPVC rainwater goods/windows and cladding. Also was given information from the client.
Why did you need to raise the garage floor?
It was constructed lower than the house GF level.
Concern about water intrusion from the garage to the house Fuel or hazardous liquids or vapor leaking into the house
What did you need to consider for the ground floor level disabled WC?
To upgrade:
damp-proofing
thermal insulation.
change the level of the floor to match the levels in the existing home.
What is an occupation therapist report?
Provides information on physical needs . The reports also usually include a description of what will assist the individual, such as equipment or adaptations.
What is PIR insulation?
PIR= thermoset plastic as solid boards.
+Strong level of thermal performance
+Faced with foil (inhibit moisture).
Why did you opt for a raised suspended timber floor?
The existing floor level to the house was high above ground, it was practicable to use timber joists, with a void underneath (minimum gap of 150mm).
- Intermediate wall with a small footing (reduce the span/thickness of joists to a minimum)
- A damp proof course (DPC) should be placed on the underside of the timber.
Insulation is then placed between the joists (thickness required depends on the product used).
Air vents should be placed underneath to provide ventilation.
Did you specify a DPM?
Yes- beneath suspended timber floor:
1200g polythene DPM to achieve a ‘U’ value of 0.19w/m2k.
How did you specify ventilation?
Air Bricks- 225x75mm air bricks no greater than 1.2 centres air bricks in external walls.
Ventilation- W/C to have one twentieth floor area ventilation by means of an opening window or door to external air, night or trickle vents of 4000sqmm to be provided. 1 no. NuAire Faith Fan to be linked to the light switches and to operate intermittently with a 15-minute overrun or be humidstat or movement sensor type. Extracts to be ducted to external air using PVC flexible ducting.
Did you specify a Fire Door?
No, as the garage had been sealed with new single skin block partition with 30 minute fire resistance. Also had fire resistant plasterboard and intumescent fire collars.
What did you consider when specifying the drainage?
Installation of a 100mm SVP housed within sound insulated ducts. (Extend above ceiling of WC)
Install Air admittance valve
Sanitary pipework to comply to BS 12056.
Underground drainage to comply with BS8301:1985 ensuring compliant falls/levels.
Drainage passing through walls are to have PCC lintels
Drains under building = 150mm concrete surrounD
Drains outside = 150mm pea shingle
Install 450mm inspection chamber.
What is included in a Doc M pack?
Doc-M packs are created to comply with UK Building Regulations Document M ;
Grab rails in a variety of colours and designs
Toilet cisterns in a variety of styles depending on what you want (including exposed cisterns and concealed cisterns).
Toilet pans,
Toilet basins
Toilet and cubicle fittings
Mixer taps
Lever or Push function flushes
What is U-Value
Thermal transmittance (heat through a structure).
Lower U-Value the better.
What is the unit of measure for U-Value?
W/m²K.
watts per square metre-kelvin
What is a R-Value
Thermal resistance of a material of a specific thickness.
Higher R-value the more effective it is at insulating.
What is Approved Document H
Drainage and waste disposal: Approved Document H (2015 edition)
What is Approved Document H- Key Sections?
1) Foul water drainage
2) Wastewater treatment systems and cesspools
3) Rainwater drainage
4) Building over existing sewers
5) Separate systems of drainage
6) Solid waste storage
What is a greywater system?
Used water without toxic chemicals/exrement.
What is clean water?
Clean water such as rainwater
What is black water?
Contaminated water with toxic chemicals/excrement
What did you consider in relation to AD H?
I had to consider the Foul water drainage, the first section for recommended widths and levels.
What key regulations did you consider whilst undertaking this instruction?
Building Regulations 2010
When do you require building regulation approval?
When you are planning to carry out ‘building work’ as defined in regulation 3 of the building regulations.
Includes:
*Put up a new building
*Extend or alter an existing one
What are the building regs?
Minimum standards for design and specification of contrcution of new building, extentions and alterations.
