What is the difference between a bathroom pod and a traditional bathroom construction
A bathroom pod is built off site within a factory and is delivered ready to be installed straight into the building, while traditional utilises all the trades required.
How much typically is a bathroom pod
Typically saw they were £6-9k depending on size and level of spec
What is the advantages of a bathroom pod
Speed of install much greater
No trades required on site e.g. ceramics/tiling
Volumetric/standardised so could be cheaper if economies of scale applied
Some disadvantages of a bathroom pod?
All the units have to be the same so no real chance for bespoke to each unit
Can be more expensive if a smaller scheme
Long lead times
What is brick slip construction?
Brick slip is a type of cladding where brick ‘slips’ are used to form the external cladding, looking like a standard masonry wall, the slip is typically no thicker than 25mm and is fixed onto aluminium rails, which is in turn fixed onto a wall construction
Can you provide a buildup and standard thickness for masonry wall construction?
Typically from the external face (typically between 450 to 550mm)
Traditional brickwork with brick ties - 102.5mm
Cavity - 50mm
Insulation - 120mm
Weather defence board - 12.5mm
Metsec Inc insulation within - 100mm
Vapour COntrol Layer
2x Layers of Plasterboard - 25mm
What is a BMS?
A means of controlling centrally:
Lighting.
Heating, ventilation and air conditioning (HVAC).
Fire, smoke detection and alarms.
Motion detectors, CCTV, security and access control.
ICT systems.
Lifts.
How was your project heated?
LTH- Air Source heat pump
QSL- Air Source heat pump
BHS - VRF
Types of aircon system?
Cooling module in MVHR
Fan Coil Unit (2 pipe or 4 pipe)
Chilled Beams
How is your project powered? And how is it distributed throughout the building?
PV Panels
Generator
Energy centre which will be fed by a local substation feeding from the National Grid
Electricity will be distributed via a switchboard
What are the different ways of fire detection?
Fire alarms
Centralised panel
Break glass
Smoke detection
What are the different ways of fire suppression?
Sprinklers
Mist system
Wet riser
What are the different ways of security?
CCTV
Alarms
Access Control
What is a dry / wet riser?
Wet risers are used to supply water within buildings for firefighting purposes
A Dry Riser is a normally empty pipe that can be externally connected to a pressurised water source by firefighters
What is the difference between an air source heat pump and ground source heat pump?
ASHP relies on air to provide heat, through a heat exchanger, refrigerant is heated
GSHP uses natural heat from the ground to provide heat, through the heat exchanger
