What are the types of site investigation?
The different stages of site investigation are reconnaissance, data and map study, in-depth or intrusive site investigation, and laboratory testing.
What is a Phase 1 site investigation?
Phase 1. Phase 1 involves a desk study which reviews records, such as old maps and historical photographs of the site and neighbours to determine if there are any potential sources of contamination at the site that require investigation.
What is a Phase 2 site investigation?
A Phase 2 Site Investigation is the second stage of a phased contaminated land assessment that is often required to discharge planning conditions or remove objections, once planning permission has been granted.
What does a site investigation consist of?
A site investigation involves the collation of desk study information; appraisal of the data; assessment of the ground conditions; and the provision of an interpretative report.
What are the 3 stages of site investigation?
Site Investigation is grouped into the following stages: Soil Investigation. Geologic survey maps. Preliminary investigation.
What is a preliminary site investigation?
Preliminary site investigations, or PSIs, are conducted to determine the relative risk of site contamination being present on a given piece of land, (i.e. answering the question ‘is this potentially contaminated land’?). PSIs may be also referred to as a Phase 1 report, or Phase 1 site assessment.
What are the stages of a site investigation?
Site investigation can be broadly classified into four stages: reconnaissance, data and map study, in-depth investigation and laboratory testing.
What is a Phase 1 contaminated land assessment?
A Phase 1 contaminated land risk assessment is used to evaluate the potential for these to substances to cause harm or damage, consider the level of risk they represent and whether any actions are required to manage or mitigate that risk.
How much does a Phase 2 environmental cost?
The price of a Phase II Environmental Site Assessment can vary, depending on the aspects of a property. The Phase II Environmental Site Assessment cost is typically between $5,000 and $8,500 (for a standard commercial lot). Sometimes, Phase 2 ESAs can cost as much as $25,000.
What stage is the first site investigation?
Site Reconnaissance Site reconnaissance is the first stage of site investigation. In this stage, visual inspection of the site is done and information about topographical and geological features of the site are collected.
How long do site investigations take?
In some circumstances we have been able to produce a Phase 2 site investigation report in one week. Usually, they take three to four weeks to allow time for laboratory testing and mobilisation of drilling crews or excavators.
What triggers a preliminary site investigation?
The purpose of a PSI is to assess the potential for contamination of a site. Typical triggers of a PSI include: Part of establishing a baseline of contamination conditions prior to lease or sale; and. Part of your lease conditions.
