December 2, 2022What is an Underground Survey?
An underground survey is the application of geophysical techniques to explore and create a digital representation of the underground and what is buried there that could hinder a construction project. Our expert surveyors use the latest laser scanning technology and equipment, such as Electromagnetic Locators (EML) and Ground Penetrating Radar (GPR), to determine all the buried underground utilities. Identifying these utilities helps in project planning as the engineers will understand the layers, structures and objects below the ground.
How can an Underground Survey help your Project?
Underground surveys help in the design and planning stage. The survey ensures the project manager and the builders have a clear understanding of all utilities below the ground. With this survey, the design will only be done once without the need for adjustments arising from unforeseen utilities beneath the ground. Our accurate and reliable underground surveys optimise the connection of new site supplies based on existing utilities, indicating any possibility of utility diversions in the planning process. It therefore mitigates potential challenges related to various utilities on the ground, including electrical connections, industrial components and more.
The drawings and representation of the objects and utilities under the ground are produced digitally. This facilitates swift and accurate access to the relevant data on the underground structures and components, leading to highly reliable and accurate results.
Health and safety issues: the survey minimises the overall risks as the workers already know where all utilities and objects are located under the ground, increasing the health and safety of workers as well as the public. It is important to consider the health and safety before commencing any excavation process. Guaranteeing health and safety enables underground surveys to help address the project's crucial aspects of the builders’ wellbeing as well as the general public surrounding the construction site.
Underground surveys will help you avoid surprise discoveries during a construction process, hence saving on cost and time. Objects discovered in the course of a project construction will not only require additional costs, but will also be time-consuming. Imagine starting an excavation only to realise that underground utilities cannot allow smooth progress of a project construction. Receive accurate and reliable underground survey results from our experienced professionals to help you with project planning.
Underground surveys render invasive underground inspection unnecessary. City’s underground survey services will help you save on both time and other expenses that would otherwise be spent in planning for invasive inspections, which still produce limited information.

City Measured Survey services enhance the confidence of builders and project managers before beginning excavation, making the excavation process move faster and devoid of any delays. Lacking sufficient knowledge of the underground utilities makes builders and project managers to be more cautious during their excavation work. This will potentially slow down the construction process, resulting to project delays.
Conducting an underground survey enables a project construction to comply with BSI standard PAS 128 Survey regulations. The underground utility surveys provide a representation of the underground, showing all the utilities and objects beneath. The survey provides a clear indicator of conformity with the PAS 128 standards as required in the UK before breaking the ground for infrastructural projects.
