GeoCon Site Investigation have operated in the UK for over a decade.
If your company has a project for Site investigation in St Helens which needs expertise then please get in contact. We provide site investigation (Desk studies), ground investigation, geotechnical and environmental consultancy, geothermal and Site investigation in St Helens and the surrounding areas of the UK.
Our St Helens site investigation consultants and contractors specialise in environmental (geoenvironmental), geotechnical & geothermal consulting with construction industry focus on ground engineering and engineering geology for Brownfield and Greenfield land.
Ground investigation St Helens is the most fundamental part of the site investigation as a whole. Following the results of a Phase I Preliminary Risk Assessment, when a Phase II site investigation is required which en-compass’s the ground investigation. The ground investigation involves the fieldwork’s part of any project and includes intrusive work such as trial pits and boreholes.
We offer Window sample and windowless sample boreholes St Helens using a tracked rig and can reach depths of around 6.00 to 8.00mbgl depending on ground conditions. Hand held equipment is used on sites in St Helens with difficult access or where borehole positions are on existing slopes. Window sample boreholes the cheapest form or borehole and can usually drill approximately six locations in a day.
Phase I Site Investigation or Preliminary Risk Assessments as they are technically termed (desk studies) are prepared by our environmental consultants to gain a profile of a site to establish its environmental setting including the site history, geology, topography, hydrology, hydrogeology, mining history, and nearby landfill sites.
GeoCon undertake Phase II Site Investigations of both Previously Developed Land and greenfield land. Our environmental site investigations are designed using both targeted and non- targeted approach based on information collated during the initial Phase I Preliminary Risk Assessment and are subsequently executed using a range of intrusive site investigation techniques.
Phase III Remediation is carried out as a result of the Phase II Site Investigation and the recommendations within. If a site is deemed contaminated and is not currently suitable for use, then remedial measures are required to ensure the site is brought up standard and is suitable for use for its intended purpose. Phase IV validation. The final phase in the phased site investigation process. Once a site had been determined as contaminated and requires remediation is some form, the act of validation or verification is to prove that the remedial measures have been carried out to specification. GeoCon would then provide a validation report to evidence this which would be submitted to the local authority to discharge any planning conditions.
Ground Investigation is essentially site investigation but more focused on the geotechnical information required to facilitate geotechnical design. GeoCon provide geotechnical consultancy services advising on the geotechnical and engineering parameters of the soils and rock beneath a site to facilitate foundation and substructure design. GeoCon also operate as a Ground Investigation contractor as part of a more traditional approach whereby a principal designer has been appointed and we are required to carry out ground investigations on a factual basis to provide pertinent information to the design engineers to allow them to prepare their geotechnical design.
Coal mining has been an influencing part of history and industry over the last 200 years and the impact that it has left is also quite extensive. In areas of former coal mining, developments are at risk from mining of shallow coal seams were voids are left in the ground, and from former mine entries such as shafts of adits which have not been properly treated, all of which could cause settlement and or collapse of structures if not properly mitigated. Risks are also posed by the presence of mine gasses that can migrate into structures. GeoCon provide both Preliminary Coal Mining Risk Assessments (desk study) to initially advise on whether a risk is present, and also Intrusive Coal Mining Risk Assessments aimed at investigating any risk identified from the Preliminary Coal Mining Risk Assessment. GeoCon have a vast experience in designing and undertaking Coal Mining Risk Assessments and investigations.
The National Planning Policy Framework (NPPF) encourages the use of sustainable drainage systems where suitable, for new developments and construction work. GeoCon undertake Soakaway Investigations to provide and advice on whether sustainable drainage will be suitable or not in the first instance, and where appropriate provide infiltration rates to facilitate Soakaway design.
GeoCon have carried out site investigations for all types or property development including residential, commercial and industrial development. Typically Phase I Site Investigation (Preliminary Risk Assessments / Desk Studies) followed by Phase II Site Investigations are undertaken to determine any risk from contamination and also facilitate foundation design. Please call now for assistance with your project.
Similar to property development Phase I and Phase II site investigations are carried out on land prior to its sale to ensure there are no issues with a site and to ensure the seller receives maximum values for their land and the buyer understands any potential concerns which may render the property not worth investment. It is vital that both parties understand any potential issues with any piece of land and this due diligence process is essential when buying or selling land.
GeoCon conduct ground investigations for infrastructure such as pipe lines, electric cables, sewer networks etc, for a range of clients including utility providers, main contractors, and civil engineers to facilitate the design and implementation of such infrastructure. Please enquiry within for any projects that require ground investigations services.
GeoCon specialise in ground investigation services for highways, bridges and tunnels, and have been involved in several major highway and bridge projects, which include major road improvements, highway widening schemes, retaining wall schemes, and brand new proposed highways. We have recently carried out a site investigation for a tunnelling project in Sevenoaks, Kent.
GeoCon also work within the rail sector and are RISQS (formerly Linkup) approved. Carrying out ground investigation projects for clients such as Networks Rail, civil engineers, and main contractors, we have the knowledge, expertise, equipment and flexibility to perform to our client’s high expectations.
GeoCon are currently working with a number of wind turbine installers and have a range of clients within this sector. We specialise in ground investigations from a range of turbine sizes from small turbines for domestic properties, to medium sized turbines, and the larger turbines, and entire wind farms. With our knowledge of these type of site investigations including difficult terrain and remote locations, we have a vast level of experience and are confident we can offer your company the right solution for your project.
GeoCon undertake ground investigations for flood defence schemes on behalf of major clients and the environment agency to facilitate subsequent flood defence design. Recent projects include Leeds FAS, Paul Flood Defense, Hull and Owston Ferry Flood Defence Scheme.
