Technical Appraisals

Overview

1.4_overview.jpgLEAP’s Initial Technical Appraisals provide the client with a fast, effective and affordable initial assessment of a site. By analysing whatever information is freely available or provided by the client, and utilising their own vast geotechnical and geo-environmental knowledge, LEAP can produce a concise report which summarises salient site features including site history and environmental sensitivity, and provides initial recommendations for both geotechnical and geo-environmental aspects.

 

 

Report Types

Standard report – (Desk Based) Client supplied data, plus free web-searches, geology check etc.

With Envirocheck – (Desk Based) as above plus Landmark Envirocheck search and summary

With Walkover Survey – as above plus site walkover survey

 

Historically the site comprised part of a gas works and was more recently a builder’s yard. Contamination associated with the site’s former use and buried structures including gas holder bases and liquor tanks were anticipated on site. The site is located on a principle aquifer (Chalk) and adjacent to a sensitive tidal river. Redevelopment of the site with housing was proposed.
LEAP was appointed to carry out a review of the previous investigation reports carried out by others and to produce quantitative risk assessments for both human health and controlled waters for the site to provide remedial targets for site clean-up.
Seven intrusive investigations undertaken by various parties had identified elevated levels of petroleum hydrocarbons (TPH), phenols, cyanide and Polyaromatic hydrocarbons (PAH) as well as heavy metals in the shallow soils. Groundwater sampling detected similar contaminants in the shallow groundwater. Slightly elevated levels of TPH, PAH, phenol and metals were also detected in the deep groundwater within the chalk. River water samples both up and downstream of the site contained traces of cy

Added Value

 

Due to the concise nature of our Initial Technical Appraisals, LEAP can provide clients with salient site information within a very short time frame. Various levels of technical appraisal report are available to suit the client’s budget and requirements.

The reports are particularly suited to due diligence assessments, and the concise format makes them very popular at senior management / boardroom level..

The reports are also used as an interim investigation report, when provision of site data and initial findings is required immediately after a site visit.
