Chiswick High Road, London
March 2022
RML were commissioned to carry out both a Phase I, non-intrusive, Desk Study and Phase II, intrusive, Site Investigation in Chiswick, London for a development of a New Travelodge Hotel.
Walkover Survey by RML Engineer
A walkover survey was carried out by an RML Engineer to establish if contamination is present from any undocumented practice or industrial use of the land and surrounding land and if necessary to confirm the accuracy of the information obtained from elsewhere as part of the Preliminary Risk Assessment (PRA) data gathering process . A visual assessment of the land to check for signs of industrial activity, landfilling, fly tipping , fuel storage, fuel tanks, asbestos related materials or any land contamination was undertaken and a photographic record made to provide evidence to show the condition of the land at the time of the Walkover Survey.
Phase I Environmental Risk Assessment
Environmental data, comprising geo-environmental hazards, hydrology and hydrogeology, was obtained for the current site covering an area of up to 1000m from the site boundary.
Historical Maps
Historical Ordnance Survey maps were also obtained for the site, as part of the PRA data gathering process. These maps were used to inform of potential historical contaminative processes.
Fieldwork
Fieldwork was undertaken in line with British Standards BS 5930:2015+A1:2020. 2 No. Cable Percussion Boreholes, 4 No. Drive-in-sampler Boreholes, On-site UXO support and Land-Borne Gas Monitoring.
Laboratory Testing
Natural Moisture Contents, Atterberg Limits, Quick Undrained Triaxial Compression Tests, pH & Sulphate tests, Chemical analysis, Asbestos Identification and Waste Acceptance Criteria (WAC) tests were Laboratory tests undertaken for this project.
East Finchley, London
March 2022
RML have now been commissioned to carry out both Phase I, non-intrusive, Desk study and Phase II, intrusive, Site investigation for the development of 20 new dwellings in two separate blocks at a site in East Finchley.
