inspection Flashcards
Talk me through surveying safely in the context of inspection ?
What do you take with you on an inspection?
Phone
Notebook
PPE
Plans
Pen and paper
Measuring tool
What are the reasons for inspection?
Valuation (factors effecting)
Property management (policing the lease)
Agency (Marketing)
What is common building defect?
Industrial
Corrosion
Impact damage
Leaking roofs at valley gutter
4 Steps of an inspection?
Desk-top/ H&S
Location/ situation / local area
External
Internal
What is your companies lone working policy?
Update shared outlook calendar - location, times and who you are meeting
Phone fully charge
nominate buddy
Did you under take a risk assessment? L2
Yes - Desktop knew that there were varying uses so took standard ppe and that we would be provided with additional ppe
External inspection?
Car park
loading doors
access
yard area
boundaries
architecture
Defects to elevations?
Internal
Specification
Fit out
defects
compliance - AMP
Compliance with lease obligations
Repair
4 types of foundations
Trench - resi, for walls and closely spaced columns
Raft - slab foundations over the whole site, sandy soil
Piled - concrete cylinder go deep in to strata for poor loading bearing soils
Pad - slab foundation under groups of columns so that load is spread evenly
Brickwork
Solidwall - Flemish bond
cavity wall - no headers, Stretcher bond (running bond), evidence of cavity vent
Efflorescence
White marks caused by hydroscopic salts in the brick work. react with water, water dissolves and leaves salt
Spalling
Damaged brick work where surface of the brick crumble due to freeze thaw
Shop spec
steel or concrete frame
service capped off
shell condition
no shop for ready for fit out
BCO office spec
Raised floor (void of 150mm)
2.6 to 2.8m floor to ceiling
Suspended ceiling void of (350mm)
floor loading 2.5 to 3 kn sqm
air conditions
double glazing
1 cycling space per 10 staff
8m2 to 10m2 workspace density
lifts
Air conditioning
VAV - Variable air volume (high costs but most flexible)
Fan coil - (lower initial costs & good flexibility, high maintence)
VRV - Variable refrigerant volume (low capex high running costs)
Static cooling - chilled beam and displacement heating
Comfort cooling
R22
low temp refrigerant that is band from 2015. R22 systems need to be modified to be more environmentally friendly
Types of fit out
CAT A - Cat A fit out is a basic operational fit out that provides you with a finished, empty space that is ready for you to move into
CAT B - fitted to occupier requirements
Shell and core
Industrial spec
8m eaves
40% site coverage
5 -10% office composition
1 door per 10,000 sq ft
loading capacity of 30kn/sq m
steel portal frame
steel profile sheet elevations
10% roof lights
LED lighting
What would you do if you found defect?
Take photo
establish cause
inform client
recommend advice via building surveyor
Subsidence
Vertical downward movement of a building foundation caused by loss of support. Could be due to changes in underlying ground condition.
Heave
Expansion of the ground beneth part or all of the building. could be due to removal of trees
Horizontal cracking?
indicate a cavity wall tie failure in brick wall
Thermal expansion cracks
wet rot
Wet rot caused by damp and timber decay. signs include wet and soft timber, high damp metre reading, visible fungal growth and a musty smell.
dry rot
Dry rot, caused inside by a fungal attack. Signs include fungus, known as mycelium, spread across the wood in fine and fluffy white strands. orange fruiting body, red spores, cracking paintwork and crumbling timber.
3 types of damp
rising damp
penetrative damp
condensation
rising damp
usually stops at 1.5m
Condensation
can be caused by a lack of ventilation and background heating. Signs include mould and streaming water on the inside of windows or walls.
what else can cause damp
leaking plumbing/ air conditioning units / pipework.
Common building defect of period properties
dry and wet rot
damp
tile slippage
death watch beetle
water ingress and damp penetrations
Common building defect of industrial buildings
leaking roofs
impact damage to floor or elevation
frame damage
cut edge corrosion
blocked valley gutters
cracking in masonry brick
Modern office building
damp penetration
water damage, burst pipes or ingress from roof
structural movement
damaged cladding
cavity wall tie failure
poor mortar joints in brick work
nickel sulphide inclusions
Legislation regarding contamination
Environmental Protection Act 1990
Talk me through the phases of contamination investigation
1) Review site history with a desk top study and inspection/ investigation
2) investigation to identify nature and extent of contamination with detailed soil sample tests
3) remediation report setting out remedial options with design requirements and monitoring standards
General approach to valuation in contamination present
Do not provide advice until specialist report provided
caveat advice provided with appropriate caveats or SAs
deduct remediation costs from gross site value
If valuing on continued use the normally okay but again caveat..
what is a deletrious material
degrades over time causing structural problems
RAAC - can degrade at a faster rate
How would you spot raac
Building surveying report or even age 1950s to 90s building
concrete frame
modern deleterious materials
high alumina cement
woodwool shuttering
calcium chloride
what is a hazardous material
hazardous material is material that is harmful to health
Asbestos
What would you do if you came across hazardous material
immediate risk assess
is there a threat to myself and my colleagues
if so leave
report to client and request relevant surveys and reports are carried out before re entry.
What is JKW
invasive plant that can damage hard surfaces such as foundations and tarmac
not easy to control , costly to eradicate
specialist company must be instructed to remove it
lenders may refuse to lend on it
Purple green hollow stem, with green heart shaped leafe
Can you dispose of JKW
Can only be done by a licenced professional, by using chemical treatment or digging it up and removing to a licenced landfill in accordance with environmental protection act 1990
How do you spot JKW
first consider location
Near a railway line?
reddish/green hollow stem
green heart shaped leaf
Can you let JKW spread
no it is a criminal offence under conntry and wildlife act
