At CGL, our Site Investigation services form a basic element of all our services for the built environment. As an innovative and award-winning ground engineering consultancy, we can draw on our extensive experience to design robust, pragmatic, and cost-effective solutions for site investigation, even in difficult to access sites, that will beat your expectations.
Our Site/Ground Investigation Services
At CGL, our award-winning, accredited team offers a comprehensive range of site investigation services across the UK, including:
- Site/Ground Investigation
- Construction Monitoring, Foundation Inspection and Verification
- Monitoring, Instrumentation, and Testing
We focus our clients’ concerns to invest time and money into one of the least visible but highly valuable elements of the construction process. We draw on our experience to offer guidance on risk reduction and what can be achieved with the knowledge that is provided by comprehensive site investigation services.
We have expertise in site investigations in remote or difficult-to-access situations across the UK, and we draw on a range of techniques and partners to facilitate this. We are also able to meet difficult constraints such as costs and timescales, whilst health and safety remain at the core of all our operations.
Our independence often allows the scope of CGL’s site investigation services to incorporate innovative techniques offered by our specialist subcontract partners to support the aims of the investigation and meet the requirements of the design.
Construction Monitoring, Foundation Inspection and Verification
CGL’s activities during the construction inspection process can be broadly divided into two main areas:
- Monitoring and supervision of remediation measures on contaminated land
- Inspection of earthworks and building formations
Alongside these procedures, CGL regularly provides inspection and monitoring services to temporary works schemes.
Our clients vary from major residential and commercial organisations through infrastructure and transport stakeholders to individual householders.
Our experience and knowledge of the industry and site investigation services ensure we use appropriately experienced and quality-driven ground investigation contractors as well as soil and contamination testing laboratories. This ensures our factual information is compliant with current standards and supports the interpretative and design reporting that we deliver.
CGL can also develop a detailed ground investigation specification and then undertake and review a competitive tender process should the client desire as part of a wider CGL contract management role.
Monitoring, Instrumentation, and Testing
Our experienced engineers and monitoring technicians carry out monitoring or sampling, equipped with the latest equipment to current specifications including:
- Gas Flow,
- Groundwater Monitoring
Groundwater sampling is undertaken using a variety of methods appropriate to the investigation purposes, including low-flow methods with in-line real-time measurements of various parameters. Gas sampling can also be undertaken by CGL where a specific risk is identified.
Site Feasibility and Planning Constraints
CGL is extremely experienced in site investigation services including site feasibility and planning constraints services- including phase 1 desk study services, producing clear client guidance for proposed developments based on:
- Environmental And Geological Constraints,
- Local Policy And Planning Guidance,
- Cost Implications Of Remediation,
- Advice On The Feasibility Of The Project Program
- Budgets Based On Findings
Alongside desk-based works, CGL can undertake and commission preliminary non-intrusive works such as geophysics-based surveys, and Non-Destructive Testing (NDT) on existing foundations and similar structures to further direct the scope of future works.
