STRUCTURAL SOILS LTD is a site investigation contractor that since 1964 has provided comprehensive site and ground investigation services including soil, rock and material testing, geotechnical consultancy and contaminated land assessment to clients in the UK and Europe. The company is based in Bristol, with branch offices in Castleford, Hemel Hempstead and Glasgow.

With nearly 50 years experience the company has an impressive list of clients, and a sound knowledge of all aspects of geotechnical engineering. By operating a variety of its own drilling rigs, the company can ensure that investigations are designed to suit the clients’ requirements and are completed in a cost-effective and efficient manner.

Structural Soils Ltd is an experienced Principal Contractor that employs highly qualified technical staff. Both factual and interpretative reports can be produced and rock and soil samples are tested in the company’s own UKAS-accredited laboratories.

Structural Soils Ltd is a member of the RSK Group.

 

Structural Soils Ltd employs a wide variety of site investigation techniques from desk studies to fieldwork to suit any size of project. The team of engineers can advise on suitable methods for individual projects ranging from small-scale investigations to larger ones for major civil engineering works. The investigations usually include both geotechnical and environmental work.

Generally the following site investigation techniques are employed for the majority of projects:

  • Trial Pitting
  • Window Sampling and Dynamic Probe Testing
  • Cable Percussive Boreholes
  • Rotary Drilled Boreholes
  • Laboratory Testing

 

Phase 1 Studies

The company has extensive experience of undertaking phase 1 (environmental and historical) desk studies. These utilise high-quality site-centred Ordnance Survey historical mapping from the late nineteenth century to the present day, and comprehensive environmental database searches. This study determines if the site and surrounding area have been subject to potentially contaminative use and gives information on other aspects such as landfills, radon, watercourses, aquifers and public water supply abstractions.

Phase 2 Site Investigation

Environmental site investigation often utilises the low-disturbance technique of dynamic sampling, as well as excavator-dug trial pits and cable percussion boreholes. Standpipes are often installed for the monitoring and sampling of groundwater and soil gases by our site technicians.

We have investigated sites with varied historical uses including petrol stations, factories, abattoirs, landfills, timber treatment works, scrap yards and foundries. The proposed developments are again varied, with the most sensitive end use generally being residential.

Concultancy and Phase 3 Work

We have extensive consultancy experience in the redevelopment of brownfield land and the assessment of risk to human health and groundwater. We can assist with the design, supervision and validation of the remediation process. We also undertake liaison with local authorities, the Environment Agency and the National House-Building Council during investigation and remediation. Qualitative and quantitative risk assessments can be undertaken to ensure that remediation projects address all the issues that may give cause
for concern.

Structural Soils have been undertaking laboratory testing on soil and rock samples through our own site investigation division and through direct contact with external clients for over 30 years.

The Bristol laboratory is the largest, employing 25 staff and having an extensive range of testing facilities.  Satellite laboratories in Hemel Hempstead and Castleford, in the UK, further supplement our testing capabilities. All three laboratories hold UKAS (United Kingdom Accreditation Service) accreditation for a range of soil testing (see attached schedule), and are in the process of gaining accreditation for a range of rock tests.

Structural Soils is an experienced Principal Contractor, with certified documented systems, processes and procedures reflecting both the legal requirements of the CDM (2007) Regulations and best working practice. These systems have been developed to enable the operations of both subcontractors and other contractors working within our area of responsibility to be encapsulated and managed promoting the inclusion of smaller businesses and one-man bands, to work with or alongside us on site.

- Structural Soils holds current certification for all operations to ISO 9001:2008, ISO 14001:2004 and OHSAS 18001:2007. These three standards of quality, environmental, and health and safety management are combined as an integrated management system.

- UKAS (formerly NAMAS) ISO17025:2005 accreditation for all three in-house geotechnical testing laboratories.

- The company holds Elite Vendor status with the Altius vendor assessment scheme, which involves meeting the Altius requirements for all five of the Altius Assessment Globes (Commercial, Risk Management, Customer Service, Corporate Social Responsibility and Quality Management).

- Fera PHSI licence - licenced by DEFRA (Department for Environment, Fisheries and Rural Affairs) and the Welsh Assembly Goverment to import soils and rock from all over the world.
