Q

Tell me about the types of supply warranties and guarantees available

A

Manufacturer material warranties and workmanship warranties.

Q

What is the difference between a performance specification and a prescriptive specification?

A

Prescriptive specs give the client certainty about the end product and will precisely include what to do and in some cases how to do it. Provide more control for the client.
Performance specs set out what is required as the outcome and allows the contractors to develop the way that suits them to reaching this. This can mean more cost effective options are used but less control on the quality.

Q

What impact does a load bearing wall have? How can you identify a load bearing wall? What is a spine wall?

A

It is supporting a load, so removing it without supporting the load can result in structural failure. Undertake a visual inspection to see if other parts of the structure are relying on the wall, alternatively appointing a structural engineer to assess.

  • A spine wall is a load-bearing wall running parallel to the long axis of the building.

Q

What is an air-source heat pump?

A

ASHP are a form of low carbon heating using electricity. The pump pulls in air from outside, then uses it to heat a refrigerant liquid. As it warms up, the liquid turns into gas.

The gas is compressed to increase its temperature

Once the gas has transferred its heat, it cools down, and becomes liquid again. And returns to the start of the cycle.

17
Q

What does the RICS Guidance Note on D&S state?

A
  • Design philosophies: Occupational design, Use centred design, KISS philosphy, Pragmatic design, Critical design
  • Strategu and project brief: Vision, objective and outcome.
  • Feasibuilty - after the brief. Gather info against project brief.
  • Change control - systyems and templates for recording
18
Q

What does SBS stand for in the felt roofing systems?

A

Styrene- Butadiene- Styrene is a synthetic rubber. :
- Highly compatible with other coverings and overlaying
- Good weather resistance
- Installation - both self adhesive and touch applied are available. self adhesive was used in this instance as it is better when overlaying.
- good for high traffic areas

19
Q

What are the EPC score brackets?

A

Domestic

E - 39-54
D - 55-68
C -69-80
B - 81-91
A - 92 plus

Non-domestic

E- 101-125
D – 100 – 76
C – 51-75
B – 26-50
A – 0-25

20
Q

What is BS7671?

A

British standard for electrical installations and safety of electrical wiring systems.

21
Q

What other codes of practice or regulations would you require for the lighting install?

A

Part P of building regs
BS standards
Part L for efficeincy
CIBSE guidance for lumen levels

22
Q

How are EPCs calculated?

A

Calculted by an accredited assesor, using an SBEM (Simplifiedd Building Energy Model) and considers factors such as:
- Build quality
- Size and shape
- Use
- Glazing and insultation
- Insultation levels
- Type of heating system
- Lighting installed
- Ventilation
- Age and construction of the building
- Any reneable energy used

23
Q

What does RIBA stand for?

A

Royal Institute of British Architects

24
Q

What did you specify in respect to the LED lighting for the Hornchurch retail unit?

A

I specified the design supply and install of the LED lighting:

Linear LED lighting
500 lux level
BS7671
Undertook a high-level mark up of the proposed locations requesting that the contractor verifies this complies with the lux levels through provision of lighting drawing.

25
Q

How did you approve that teh contractors design was compliant?

A
  • I reviewed the tech subs and lighting calcs to model and that the appropriate lux levels would be reached.
26
Q

What different light fittings are there?

A
  • LED
  • Fluorescent
  • Halogen
  • Induction
  • Metal halide
  • Incandescent
27
Q

What are some requirements from BS7671?

A

Otherwise known as the IET wiring regulations some key outputs are:

  • Safety requirements - proction against electric shock and overcurrents
  • Design and installation - circuit design, switching and control, requirements for emergency lighting
  • Energy efficiency and lighting quality
  • Documentation
28
Q

What are some key delvierables from each RIBA stage?

A
  • Strategic Definition - Client requirements & business case for project
  • Prepartion and briefing - Project brief, feasibilty studies, site info, budget, programme, procurement strat, responsibilty matrix, RFIs
  • Concept Design - Brief derogations, stage report, project strategies, outline spec, cost plan
  • Spatial coordiantion - stage report, updated outline spec, cost plan, planning application
  • Tecnhical design - manufacturing info, construction info, final specs, building regs application
29
Q

What is a Uniclass 2015?

A

A voluntary classification system that can be used to organise information throughout all aspects of the design and construction process.

30
Q

What do you typically include in a specification?

A
  • Performance criteria
  • Quality of products
  • Reference to applicable standards
  • Products or materials to be used
  • How work is to be completed and tested
31
Q

What is an open lap joint and why is it a problem?

A

Open Lap joints are when the overlap of each of the bitumen sheets has begin to lift. This can be due to thermal movement over time and/or poor workmanship.

It can allow water to get below the membrane and cause damage to the structure beneath.

32
Q

What SBS system did you specify, what was the build up and why did you use this system over others?

A

Specified an IKO Ultra Gold system.

The roof was a cold roof with a build up comprising:
SBS membrane
Chip Board
joists with insultation inbetween
plasterceiling

Chose system due to:
- Durability
- Guarantee was available
- Needs to be able to be walked on

33
Q

Draw me a cold and warm roof build up?

A
34
Q

What are the pros and cons of a warm and cold roof?

A

Warm
- Better thermal and energy efficiency
- Easier to install
- More expensive

Cold Roof
- Cheaper to install
- Ability for pedestrian access across
- Ability to put planting or heavy objects

35
Q

Did you need to get building control approval for your roof overcoating?

A

Yes as this would have triggered guidance under Approved Document L, i ensured the roofing contractor was part of the competant roofer scheme that allows the roofer to self certify their own roofing installations.
