A feasibility study can determine whether a project will be viable depending on the proposed environment and route. Ensuring that a feasibility study is used will assist in increasing design and construct-ability confidence.
Risks can be assessed and more complex issues such as planning permissions and land use regulations can also be addressed during the feasibility study stage.
We aim to collate all necessary information to provide a safe and economical solution for our clients when it comes to Underground Utility Detection and Geotechnical surveys at the drill location. We then enhance the package with our wide knowledge of best practices and our bespoke 3D modelling software allowing us to calculate ground movements in the proximity of the drill, both vertically and horizontally.
Once the model is built, we fine-tune the launch and reception positions and the drill alignment with the project specific requirements based on the information gathered from the relevant authorities and asset owners, project budget and practicality.
Underground Utility Detection (UUD)
Underground Utility Detection surveys are recommended before breaking ground to assist in complete worker safety. All of our Underground Utility Detection (UUD) surveys meet industry standards and we are able to provide all levels of PAS128 quality levels for our in-house services. Our UUD surveys are internationally awarded and recognised for their quality and innovative approach.
Both electromagnetic location and ground penetrating radar are used to detect each utility within the survey boundary. Each detection method is recorded geospatially, and data compared against each other and existing utility records. By evaluating this data, a clearer understanding and parameters of confidence can be established.
Our Topographic survey service includes land surveys, utility survey recording, high detail substation surveys, rail and highway layouts. These surveys are used for design, cost management and asset management. All data is processed and delivered in our award winning ‘intelligent’ document format to provide a topographic overview.
Laser Scanning and 3D Modelling
Our specially trained laser scanning team uses the latest laser scanning technology in order to produce the correct level of detail required.
Network Distributors must help customers connect to their network in a timely and efficient manner. Sometimes a new connection can require an upgrade of the existing network, this is so that the connection can be made without affecting other customers quality of service.
We at Catsurveys liaise with all statuary undertakers and local authorities to plan and carry out a feasibility for a new connection that are:
- Cost effective for the customer
- Minimal impact on the carbon footprint
- Achieve new connection customers delivery dates
- Taking into account that the new installed asset is feasible / strategical located so that any works on the asset in the future is safe to do so
Recording Control Assistant / Asbuilt
We provide as-built surveys at varying points during the construction process to monitor the construction as it is occurring. We can provide valuable information including the level of completion that the project has reached and if the construction is following the original design.
Our clients can use this invaluable information to extend deadlines if needed, and when violations are found it can be used in remediation procedures. As-builts can be carried our using topographic survey methods, laser scanning, Ultra-Wide Band GPR, Underground Utility Detection and Gyroscopic Mapping.
By using the latest technologies available including hand auguring, conventional and cut-down cable percussive rigs, light and dual mast dynamic samplers, heavy duty rotary and sonic drilling rigs, we aim to offer you a tailor made, versatile approach to delivering the best outcomes for your specific site requirements.
We also offer rotary diamond coring to investigate structural makeup and integrity of all hard surface materials and for examination of brick, concrete or composite structures, with both vertical and horizontal drilling available. Diameters range from 50mm to 250mm, with larger sizes being available on specific request.
This is suitable for all hard surface materials and for examination of brick, concrete or composite structures, with both vertical and horizontal drilling available.
Trial Hole Excavation
May it be hand dug, machine or vacuum excavation on fields, verge, footway or carriageway we plan to deliver the safest and most economical solution to discover the underground services or structures you are looking for. Using the latest in photogrammetry techniques we are able to produce 3D as-built, measurable models of the excavation.

UXO Surveys and Reporting
Utilising our specialist equipment, we can record and plot anomalies caused by any significant metallic objects underground. Depending on the risk and site conditions we will choose the optimal type of survey to provide you with the data you need for your scope of works.
Catsurveys can offer a very fast and cost-effective preliminary report that establishes whether further research is required. We are also able to discover whether the risk can be negated at that stage without the need for a further UXO report.
Alternatively, we offer a comprehensive and in-depth UXO survey report which full examines the history of the site. This data gives our clients the confidence that they can put plans and support in place to ensure works proceed safely and on schedule.
Working alone or in partnership we carry out the following in-situ Geotechnical testing:
- Cone Penetration Testing (CPT) is used to determine the strength of the subsurface and design load of the soil. Once the maximum design load of a soil is known, these results can be used to calculate appropriate footings and foundations for sub/superstructures to be placed on or within the soil.
- CBR testing is conducted to determine the strength of a material (usually a subgrade) when it is at its maximum compaction. This purpose of this is to determine the required thickness of a structural layer or asphaltic layer (e.g. a footpath) to be placed on top of the tested material. This test ensures that the strength requirements outlined by the scope of works are satisfied.
- Standard Penetration Tests (SPTs) provide in-situ information about the density of granular deposits, such as sands and gravel.
- Heavy (HDP) & Super Heavy Dynamic Probe (SHDP) testing is used to determine the resistance of in-situ soils. Our in-house Geotechnical Engineers carry out comprehensive reporting as appropriate to our client’s requirements.
- Thermal Resistivity (TR) testing measures the capacity of the ground to conduct or dissipate heat. A correct understanding of the thermal properties of a soil or made ground is important for the design and installation of underground pipelines and transmission cables, as improper installations often can lead to premature failures.
