What are the characteristics of a Grade A office?
- Prime Location
- Steel or reinforced concrete frame
- LEED or BREEAM certification, green roofs, energy-efficient systems, and water-saving measures.
- HVAC systems
- Excellent DDA,
- suspended ceiling with 350mm void
- 2.6 clear floor to ceiling height
What are the characteristics of a Grade B office?
- Grade A 10-20 years ago
- Well maintained
- Systems are functional but no longer industry leading
What are the characteristics of a Grade C office?
- Located in less desirable area
- Older than Grade A or Grade B
- Out of date furnishings and no DDA access
- Poor maintenance
What are the two main methods of construction of new office buildings?
Steel frame - less columns and wider span between columns
Concrete frame - more columns, lower floors heights, shorter spans between columns
What are the different types of air conditioning systems?
VAV - high cost but flexible
Fan Coil - low cost initially but high running cost
Mechanical Ventilation - fresh air is moved around the building
What is R22 refrigerant?
- Colourless gas used in refrigerant air conditioning
- Illegal as greenhouse gas
- Ban includes topping up with R22 - can continue using systems until tehy are obsolete but must use R44 10a or new system.
What is difference between CAT A and CAT B fit out?
CAT A - fit out of shell and core basic internal framework of building
CAT B - A finished office space that has been tailored to teh exact requirements of the client
What is the difference between comfort cooling and air conditioning?
-Comfort cooling focuses mainly on cooling the air
-Air conditioning provides full climate control with both heating and cooling capabilities, as well as more advanced humidity and air filtration functions.
What is HVAC?
Heating ventilation air conditioning
- refers to the systems used to regulate indoor environments, ensuring comfort, air quality, and proper temperature control in buildings.
What is a portal frame?
- Structural framework commonly used in industrial
- Two vertical columns, connected by a horizontal beam forming a rigid trapezoid shape
/\
[ ] - Typically span 15-50m
- Wall and roof cladding: plastic coated profiled steel sheeting with insulation
What is the basic construction of an industrial or warehouse premises?
Portal steel frame
Profile sheet cladding
What are the benefits of a portal frame structure?
- Rigid Joints - structure and strength
- Clear Span - no need for internal supports -> large open space
- Efficient Load Distribution - lighter construction materials and reduced building costs
- Cost-effective and Fast Construction
What is considered optimal site cover for an industrial development?
- Lower site coverage (40-50%) is often recommended in suburban or semi-rural areas where there is a need for landscaping, parking, and logistics space (e.g., truck maneuvering).
- Higher site coverage (50-60%) is more common in urban or industrial zones, where maximizing building footprint for manufacturing or warehousing operations is critical.
What is the floor loading requirement for industrial buildings?
30/40 kilonewtons per square meter
What is typical office coverage for industrial properties?
10% of total floor area
What is the typical fit out of industrial properties?
Roller shutters
High ceiling
Docking bays
Basic office fit out
Level dockers
CCTV
What is a dock leveller?
Height adjustable platform used to bridge the difference in height and distance between warehouse and vehicle
What is 3 phase power and why is it needed in industrial properties?
- Accommodates higher loads to service lots of electrical equipment
i.e plant and heavy machinery, HVAC, motors and pumps
Describe a typical industrial warehouse?
- Steel portal frame
- Profile steel cladding
- 10% office space
- Concrete screed floor
- 3 phase electricity
- Roller shutter doors
- 40 kilo newtons per square metre loading capacity
What is the Apex point?
The highest point on a building – top of the roof pitch
What is a typical retail unit fit out?
- Cat A or B (same as offices)
- Suspended ceilings or Acoustic Panels (for larger retail)
- LED lighting
- HVAC
- Partitions
- Shelves & Displays
What is the typical build specification of new retail units?
- Steel/concrete frame
- Vinyl covered concrete floor
- Shell condition for retailers to fit out to their own specs
Where will brickwork typically crack?
Along mortar joints or the narrowest section
What are the 4 types of cracking typically seen in brickwork construction?
- Horizontal
- Triangular
- Stepped
- Cracking to floor level
