Underground Service Surveying and Mapping
Information is essential for planning any project or before digging in unknown areas.
Significant cost and safety risks can be removed by planning and locating hidden underground services before you commence works. An Underground Service Survey provides the vital information required to avoid such problems and produces an accurate drawing and report for your permanent records and future developments.
QEST can provide Utility Mapping services in Melbourne, Geelong and across Victoria. Our qualified and experienced staff locate underground pipes and cables with the use of specialised Radiodetection equipment and Ground Penetrating Radar. Stormwater and Sewer networks are investigated using safe pit lifting techniques with pipe inverts, diameter and material recorded. All marked information is then captured with an Underground Utility Survey using state-of-the art Survey equipment. Above ground features such as buildings, roads, vegetation, and levels for contours can all form part of your Feature and Level Survey, capturing existing conditions on the surface. Combining both Utility and Feature Surveys is integral to the planning and success of every Project. Our team can overlay existing surveys and proposed drawings as a reference for powerful planning capability.
Our team plan your project from start to finish to suit the needs of your site. DBYD information is used as a template to further improve the Quality from Class D to C and B according to the Classification of Subsurface Utility Information (SUI) (AS5488). The benefit of using QEST is in our ability to safely NDD at key locations and upgrade your Utility Survey again to Class A, Exposed and Surveyed to sub 50mm 3D coordinates.
CCTV can also be used to investigate the condition of the pipes and detect the cause of blockages, construction materials used with all information clearly presented on the plans.
