What is a Phase 1 Desk Study?

A Phase 1 Desk Study is an interpretive report that provides detailed information on the likely presence of any contamination within the subsurface of the development site. A phase 1 Desk study highlights the sites historical, geological and environmental setting, and the potential risks that this may present to future site users, developments and the immediate environment.

A phase 1 desk study is required before ground investigation. Ideally it should also be accompanied by a walk over survey conducted by an experienced practitioner. By compiling available information in relation to a site’s environmental, geological, hydrogeological, hydrological and mining setting a cost effective and focussed site investigation will be developed

Development of Brownfield Sites

Development of Brownfield Land : Focus for Housing Development

, ,
The development of Brownfield land will continue to be a focus for the next few years in the aim to provide much needed housing throughout the UK. The Government hopes to transform unused and derelict buildings, while making the most of brownfield land. Also to tackle the housing shortage in urban areas by enabling commercial premises to be converted into new homes through a fast-track planning permission process.

Conducting Ground Investigation | Site Investigation

,
What Could Delay Your Development Construction? More than 50% of construction projects are delayed by adverse site conditions or unexpected ground conditions. Conducting detailed Site Investigation / Ground Investigations can save you time and money. There are many reason’s a development can be delayed, but one of the key factors that will affect a development is knowing what you are building on.
Slope Stability Assessment

Geotechnical Appraisal Cliff Collapse Newquay Cornwall

,
Earth Environmental & Geotechnical (Southern) Ltd were commissioned to undertake a Geotechnical Appraisal for cliff stability of a site near Watergate Bay in Newquay, Cornwall. HM Coastguard had reported a section of the cliff had collapsed in early 2020. As part of the study, a Phase I Desk Study was carried out, including obtaining a site-specific geological and ground stability report.
Phase 1 Desk Study

What Is A Phase 1 Desk Study?

,
A Phase 1 Desk Study is a risk assessment report for a development site. For planning applications to be approved, your council needs to know that your development carries no risk to human health or the wider environment. As part of the Phase 1 Desk Study information about the site is collected from a wide range of available documents
