Inspection Flashcards
What is the process of an inspection?
1) Competence
2) Risk assessment – consider personal safety (desktop and DD)
3) Inspection of local area – location, situation
4) External inspection
5) Internal inspection
What equipment would you take with you during a survey?
Pen and paper, camera, disto, PPE if necessary
What risks do you consider in inspection?
Lone working, asbestos, accessing roofs, hazards associated with derelict properties, confined spaces
What might you note as part of an external inspection?
- Method of construction
- Repair and condition
- Defects/structural movement
- Date of the building/architecture
- How many floors
- RWG/Windows
What might you note as part of an internal inspection?
- Layout and specification
- Repair and maintenance
- Services, age and condition
- Compliance with lease
Why might you undertake an inspection?
1) Valuation
2) Property Management
3) Agency
What are the different types of foundations?
Trench/strip footings, Raft, Pile, Pad
- What are Trench foundations?
Residential with closely spaced columns
- What are raft foundations?
Slab over whole site to spread load – used for light structures
- What are pile foundations?
Reinforced concrete cylinders, deeper foundations – used for high loads
- What are pad foundations?
Slab foundation system so column load spread evenly – used for industrial or larger commercial buildings
How might a brick wall be constructed?
Solid wall or Cavity walls
What is the difference between solid walls and cavity walls
Solid – at least one thick, in a variety of patterns eg Flemish bond and utilises headers and stretchers
Cavity – Tow layers thick with a gap, it has no headers, just stretchers
What could be some issues experienced by a brick wall?
Efflorescence – White marks made by hydroscopic salts in brick
Spalling – Damaged brickwork where surfaces crumbles because of freeze/thaw after being saturated
What are some different types of air conditioning?
Variable Air Volume (VAV) – highest capital cost but most flexible
Fan coil – 4 pipes, lower capital cost, higher maintenance
Variable Refrigerant volume (VRV) – Lower capital costs but higher maintenance
What is the legislation regarding R22?
From 2015 – use and replacement of low temp refrigerant illegal, existing had to be modified
What are different fit out types?
S&C – common parts completed, floors left as shell ready for fit out
Cat A – Grade A spec
Cat B – fit to occupiers’ requirements
How much space is typically allowed per person within an office?
7.5 to 9.25 sq m
What are the institutional specifications for shops?
- Either steel or concrete framed
- Concret floor and no suspended ceilings
- Services capped off
- Let is shell condition with no shop front
What are the two main methods of construction for office buildings?
Steel – less columns and wider span between columns
Concrete – more columns, lower floor heights, short span between columns
What are the institutional specifications for offices?
- Full access raised floors with floor boxes.
- 2.6m-2.8m approx. ceiling height.
- Ceiling void-350mm, raised floor void - 150mm.
- Max opportunity for daylighting 300-500 lux average.
- Floor loading-2.5-3.0 kN/sqm, 1.2kN/sqm for partitioning.
- Air conditioning, double glazing, passenger lift.
- 1 cycle space per 10 staff, 1 shower per 100 staff.
- 8m2 to 10m2 general workspace density.
What does a basic industrial construction include?
Steel portal frame with insulated profiled steel cladding walls and roof
What are the institutional specifications for industrial?
- Min. 8m clear eaves height, 10% roof lights.
- Full height loading doors (electrically operated).
- Min 30kN/sqm floor loading.
- Plastic coated steel profiled cladding with walls to appox. 2m.
- 3 phase electric power (415 volts).
- 5-10% office content and WC facilities.
- Main services capped off.
- Approx site cover 50-60%
- LED Lighting
How should you check for defects?
Start from the roof downwards
What is a latent defect?
A fault to the property that could not have easily found on inspection
What is an inherent defect?
Defect in design or material that has always been present
What should you do if you identify any defects?
1) Take photos
2) Establish cause
3) Inform client
4) Recommend relevant professional
What are the three most common causes of defect?
- Movement
- Damp
- Defective materials
What may be some signs of Movement?
Subsidence (loss of support beneath foundation)
Heave (expansion of ground beneath building e.g. tree removal or moisture build up)
Horizontal cracking (cavity wall failure in brick wall)
What may be some signs of Damp?
Wet rot (wet/soft timber, visible fungal growth, musty smell), dry rot (fungal attack, signs include fungus in fine and fluffy white strands and large orange mushroom like bodies, crack paintwork, strong smell), Condensation (lack of ventilation)
What are some of the differences between dry and wet rot?
Wet rot can only spread to nearby damp timber, dry rot is more destructive
What are some common building defects for period properties?
Dry/wet rot, tile slippage, death watch beetle, damp penetration, movement
What are some common building defects for modern industrial?
Roof leaks around lights, damaged cladding, blocked valley gutters, burst pipes, settlement
What are some common building defects for modern offices?
Damp penetration, burst pipes, structural movement, cavity wall tie failure, efflorescence, poor mortar joints
What is the key legislation regarding contamination?
Environmental Protection Act 1990
What is RICS guidance on Contamination?
RICS Guidance Note – Contamination, the Environment and Sustainability 2010
What are the step taken if you suspect Contamination?
As per RICS Guidance Note – Contamination, the Environment and Sustainability 2010:
- Typically 3 phases of investigation
1) Review site history – desktop study and site inspection
2) Investigate to identify nature and extent of contamination
3) Remediation report setting out remedial options
What are some signs of contamination to look out for?
Evidence of chemicals, oils, oil drums, subsidence, underground tanks, radon gas
What should you do if there are any concerns that a site is contaminated?
Suggest specialist report
What should be considered if instructed to value site with contamination?
