Evidence of chemicals, oils, oil drums, subsidence, underground tanks, bare ground etc.
67
What are the different phases of environmental assessment?

68
What should you do if you have concerns over contamination?
Advise a specialist report is carried out.

70
What is Land Remediation Relief?
It is a form of tax relief that applies to contaminated or derelict land in the UK and allows companies to claim up to 150% corporation tax deduction for expenditure in remediating certain contaminated or derelict sites
71
What is Japanese Knotweed?
An invasive plant that can damage hard surfaces such as foundations and tarmac
72
What does Japanese Knotweed look like?
Purple / green hollow stem, green leaves with a zig zag pattern and cream coloured flowers
73
What should you do if you have Japanese Knotweed?
A specialist company must remove or dispose of it which is costly. It must be disposed of legally such as using a chemical treatment, digging it out and removing it from the site to a licence land fill site in accordance with the Environmental Protection Act (1990).
74
What are the penalties for not dealing with Japanese Knotweed?
Allowing it to spread is a criminal offence under the Wildlife and Countryside Act 1981. ASBO amd fines of up to £2,500 if a landowner ignores it, does not control it and allows it to grow onto adjoining land.
75
What is a leading recent case about Japanese Knotweed?
Williams vs Network Rail Infrastructure Limited (2018) - Network Rail were liable for the cost of treating the plant plus damages for loss of use and enjoyment of the neighbours property, but not for the reduced value of the property (even after the plant was treated)!
76
What did the House of Commons Science and Technology Committee Report in May 2019?
That the latest research suggests that physical damage to property from Japanese Knotweed is no greater than that of other disruptive plants and trees that are not subject to the same controls and do not have the same 'chilling' affect on the sale of property.
77
What is a piled foundation and when would it be used?
Reinforced concrete cylinders burried deep within the ground with a pile top. Used for large buildings.
78
What are the two types of slab foundation?
Raft - Slab foundation over whole site Pad - Slab foundation under columns
79
When would you use raft foundations?
When the ground conditions are poor
80
When would you use trench / strip foundations?
Generally used for residential terraced houses
81
What RICS guidance would you consider when out on inspection?
RICS Surveying Safely Guidance Note (2nd Edition) 2018.
82
What are the key points from the RICS Surveying Safely Guidance Note (2nd Edition) 2018.
``` This gives guidance to firms and individuals in regard to health and safety responsibilities. It provides advice on: – Visiting premises and sites – Assessing hazards and risks – Loan working procedures – CDM regulations – Health and safety procedures at work ```
