What is the first step in identifying a contaminated land site?
Desk study
This involves collecting data about the site before any physical work takes place.
What type of sites do desktop surveys typically focus on?
Brownfield sites
These sites have been previously used and may contain waste or contaminants.
What information can be obtained from the land registry?
Owner and status of condition (freehold or leasehold)
This is crucial for understanding the ownership and legal status of the land.
What data is important for writing specifications for a construction project?
Efficiency, cost, and weather conditions
These factors are essential to ensure a successful project outcome.
What types of data are collected during desk studies?
- Ordinance survey maps
- Rights of way
- Geological maps
- Site history
- Previous planning applications/approval
- Current planning applications
- Development restrictions
- Utilities
- Aerial photography
- Ecology factors
- Flood risk and flood history
- Archaeological findings
- Proximity of landfill
- Underground mines
- Deed restrictions
This comprehensive data collection helps assess the site’s suitability for development.
What is one question you would ask during a site survey?
Is there any evidence of overburden on slopes?
This helps assess potential stability issues on the site.
What is the purpose of a field survey?
To identify types, properties, and depths of subsoil strata and water table level
This information is essential for designing economic foundations.
What is assessed during a field survey regarding existing structures?
General condition and potential hazards to health and safety
This includes checking for hazardous waste tipping and structural integrity.
What factors influence the soil investigation method?
- Size of contract
- Type of proposed foundations
- Type of sample required
- Type of subsoil encountered
These factors determine the testing procedures used in soil investigations.
What are some signs of flooding to look for during a site survey?
- High-water table indicated
- Signs of flooding
- Reeds or water-loving plants
- Springs, ponds, wells, or streams
- Discolored water
These indicators help identify areas prone to water accumulation.
Fill in the blank: A _______ study is done to assess the surface conditions including ground slope/contours.
field
This study is important for understanding potential site hazards.
True or False: A site survey includes assessing adjacent structures that might be adversely affected by development work.
True
This assessment is crucial for minimizing negative impacts on neighboring properties.
What is examined regarding vegetation during a site survey?
- Type and condition of vegetation
- Species, height, and condition of trees
- Evidence of formed trees or hedges
This information helps in understanding the ecological aspects of the site.
What must be checked regarding the site boundary during a field survey?
It matches the deeds
Ensuring the boundary is accurate is essential for legal and planning purposes.
