    Everything you always wanted to know about soakaway testing and groundwater monitoring*

    Everything you always wanted to know about soakaway testing and groundwater monitoring* (*but were afraid to ask).This was the title of a recent lunchtime CPD presentation that Simon and Callum recently gave to a company of drainage and civil engineers. Whilst the pun in the title, taken from a Woody Allen film, might have been lost on many of the audience, its content certainly wasn’t. I am all for sharing what we know, particularly if it takes less than an hour, over lunch, and especially if it helps make all of our lives easier and to the benefit of others. Whilst standing up in front of a room and talking for around 40 minutes isn’t my idea of fun, the benefits are great and many, so we are happy to provide a similar talk to others, if anyone fancies it.    Providing a pizza lunch is optional, but always helps with our availability!

    Mineral Resource Assessments, Dorset

    Mineral Resource Assessments have been undertaken for three sites in close proximity to each other for the same developer on the outskirts of village near Poole, in Dorset, where minerals resource assessments are commonly required due to the quarrying of sand and gravel deposits. Ruddlesden geotechnical carried out site-specific desk-based assessments of the superficial and bedrock geology and potential mineral resources, including the study of geological maps and memoirs, historical data, nearby borehole records, site investigation reports and British Geological Survey Mineral Resource Information for Development Plans. The mineral resource assessments, which were undertaken at the pre-application planning stage, as part of the viability assessment, identified that deposits beneath two of the sites were unlikely to be quarried, whereas further work was required to assess the risks at the third site. This information was used by the developer to help prioritise the developments.

    Pre-Purchase Phase 1 Contamination Assessment

    Phase 1 Contaminated Land Assessment for the proposed redevelopment of a brownfield site in Devon, as part of the pre-purchase appraisal for the construction of a new supermarket. The site had numerous historical industrial land uses, including an iron foundry, gas works and an engineering works, as well as documented evidence of historical contamination of the ground, associated with an adjacent gas works. The production of the Phase 1 was crucial to understanding the potential development (and cost) constraints at this site for the client, prior to purchasing, and formed the basis of the scope of works for the Phase 2 Contamination Investigation.
