What is Shell and Core vs CAT A VS CAT B fit Out
Shell and Core works will generally comprise the structure, cladding, base plant, completed common areas and external works. It will include fitted-out main reception, lobbies, staircases, toilets, lift shafts, basements, loading bays, car parking, and so on.
Category A (Cat A) generally describes the level of fit out that the tenant’s own space is completed to by the developer. There is no standard definition, but a category A fit out may include: RAF/ suspended ceiling/ M&E services etc.
Category B (Cat B) completes the fit out of the internal space to the tenant’s requirements. This may include: Final finishes/ ICT equipment/ furniture

How did you work out labour cost for the secure wall?
What were the cost on the two different options of McLeay wall?
What is service penetrations
An opening in a building’s floor or wall where pipes, cables, ducts, or other building services pass through.
Service penetrations require fire-stopping to maintain a building’s fire resistance and prevent the spread of smoke and fire.
Talk me through what you did on BT Secure
What is Lath and Plaster
a traditional building technique for finishing interior walls and ceilings.
Narrow strips of wood, called laths, are nailed horizontally across wall studs or ceiling joists.
Plaster is then applied to the laths.
What did you advise on Argyll?
F&B
Labour intensive
3 coats of paint
consistent finish will be challenging due to uneven surfaces
Surface is lath and plaster in a historic building
cannot be patch repaired
Future maintenance would be costly as colour matching would be difficult
each batch of paint is different
Longer term maintenance cost
advise the client on the long term upkeep, overall costs of the works
What did you advise on BT Secure?
Service Penetration running through the walls - what were the key cost consideration that you advised the client of?
What methods can be used to improve fire safety in construction?
Name some modern methods of construction
Two types of Air con system
How is power provided to a project typically
What are Part L Regulations?
Part L1A: Covers new dwellings
Part L1B: Covers renovations to existing dwellings
Part L2A: Covers new buildings other than dwellings
Part L2B: Covers existing buildings other than dwellings
Different parts to Part L
Part L1A: Covers new dwellings
Part L1B: Covers renovations to existing dwellings
Part L2A: Covers new buildings other than dwellings
Part L2B: Covers existing buildings other than dwellings
What type of design document would you expect at RIBA Stage 4
How do building regulations impact construction methods and material choices?
You need to comply so for example you may have to ensure that you choose materials that reduce the spread of fire under Part B. Or in terms of Part L, you may need to increase the thermal performance of your external envelope/ cladding.
Are you aware of any changes to the building regs
How do you measure steel?
I would measure the lengths of the beams and then check the weight on British steel website per linear metre. Then the length of that beam/ column x kg/m = weight of beam.
Then allow appropriate cost/ tonne (usually speak to steel suppliers as market fluctuates).
The numbers are depth x width x kg/m, i.e.
203 x 133 x 25 (note 1000kg in Tonne)
What is the difference between a hot and cold roof?
With a warm roof the insulation is on top of the rook structure (i.e. above ceiling, joists and structural deck) – this helps prevent condensation
With a cold roof the insulation is below the roof structure (between ceiling joists)
