Ruddlesden geotechnical

Ruddlesden geotechnical provides ground investigation, geotechnical consultancy and contamination assessment services.

Based in Exeter, but covering the whole of the UK, albeit primarily concentrated in the South West, Ruddlesden geotechnical was formed in 2004.

Ruddlesden geotechnical works on behalf of a wide client base, including local, regional and national housing developers, housing associations, commercial developers, building contractors, structural and civil engineers, architects, building consultants, quantity surveyors, local authorities and private individuals.

Development projects range from single dwellings and extensions to large housing estates, multi-storey flats, offices, industrial units, roads, slopes, schools, hospitals and basements.

    MSc Student to Help with BRE 365 Soakaway Project

    At Ruddlesden geotechnical, we often provide work experience to university students over the summer. This pleases both parties, as it provides them with invaluable industrial experience and a bit of pocket money, and helps us cover staff holidays, as well acting as an extended job interview, should a suitable vacancy arise in the future.This summer, we are particularly looking forward to welcoming Bailey, from the University of Portsmouth, who will be doing his MSc dissertation with us. He will be working and extending on an on-going project of ours. He will be reviewing all of our soakaway testing data and correlating this with the published geology, and then asking the question, and potentially providing the answer: does BRE soakaway testing need to be carried out in certain geologies?We have been reliably informed that he is a GIS whizz and are hopeful that he is what the project needs to take it to the next level.

    Temporary Works Excavation Stability Assessment, North Devon

    It was proposed to construct a retaining wall as part of the proposed redevelopment of a residential site in north Devon. Ruddlesden were commissioned to provide a method statement detailing precautions to be taken during excavations, with details of the support to be provided during temporary works and construction of the retaining wall. Whilst it was considered that one of the excavations could be safely graded back to a safe angle of repose to facilitate the construction of the retaining wall, where this was not possible, the soils and rock exposed in the excavation were retained by a proprietary geo-grid/ mesh pinned into the slope, to mitigate the risk of rock fall.

    Pre-Purchase Phase 1 Geotechnical Assessment Provides Cost-Effective Information

    Ruddlesden geotechnical were commissioned to undertake a Phase 1 Geotechnical Assessment on behalf of a national housebuilder at an existing golf course in Dorset. Following a review of the desk study information and the consultation of historical maps, geological maps and memoirs, a walkover survey of the site was undertaken. This information allowed a ground model to be produced, which was used to identify the geotechnical risks and current uncertainties with regards to the proposed residential redevelopment of the site. The site was zoned, based on the anticipated ground conditions, and recommendations covering foundations, excavations, surface water drainage and slope stability were provided. The findings of the Phase 1 informed the scope of works for the Phase 2 deotechnical investigation and contamination assessment and ultimately provided the client with an understanding of the development constraints, opportunities and forecasted development costs for the site, prior to committing to the purchase of the site.
