UTILITY SURVEYS
Utility Surveys are conducted to locate and map underground utilities such as water, gas, electric and communication cables, pipes and ducts for many reasons including: Pre-Construction, Design and Estate record keeping. The purpose of the survey is to reduce client risk and minimize damage to utilities while ensuring site and public safety. Surveys are undertaken in accordance with British Standards Institute’s PAS 128, which outlines possible methodologies to accurately map underground utility networks in the UK.
GEOPHYSICAL SURVEYS
Geophysical surveys use non-invasive techniques to study the subsurface of the ground, by measuring physical property data gained by applying the appropriate ground penetrating radar (GPR) survey methodology. They are commonly used to identify depth and location data for buried voids, concrete infrastructure, reinforcement bars (rebar) and tunnels for example badger sets.
TOPOGRAPHICAL SURVEYS
Topographical Surveys are detailed surveys of the natural and man-made features of a site, including elevations, contours, and boundaries. They provide a comprehensive representation of the topography, vegetation, and structures present on a site and are used in the design and planning of construction projects, such as roads, buildings, and landscapes. Topographical surveys can also provide basic information on surface features relating to underground utilities, drainage patterns, and other critical features that can impact construction plans. Topographical Surveys are essential for providing an accurate understanding of a site’s conditions and are used by architects, engineers, and planners in the development of plans, specifications, and construction estimates.
3D LASER SCANNING
3D laser scanning is a technique that can be used to create accurate, detailed and comprehensive surveys in a fraction of the on-site time it would take to manually measure the site. Scan data once collected and registered can then be processed to fit the desired outcome required. For example 3D laser scanning can be used for the following purposes: Building Surveys, Heritage Surveys, Topographical Surveys and BIM (Building Information Modeling) Surveys.
DRAINAGE SURVEY
A Drainage Survey is a comprehensive investigation of a property or estate’s drainage system. The survey includes a detailed analysis of the structure of the pipes, manholes, and gullies, and identifies any defects or faults within the system. This information is used to assess the condition of the drainage system, and to make recommendations for any necessary repairs or upgrades. The Drainage Survey is a crucial tool for land and property owners and buyers, as it helps to identify any potential problems before they become serious, and helps to protect the property from potential damage caused by poor drainage.
DESKTOP SURVEY
Surveys can be undertaken via digital records searches of data sourced from Gas, Electricity, Water and Sewerage, Pipelines and Telecommunications. They can be targeted specifically by type or a designated location. As detailed in HSG47 (hse.gov.uk), ‘Avoiding danger from underground services’, locating and identifying buried services are one of three core elements of a safe system of work for ground excavations.
