UXO contamination<\/a>, which could range from unexploded bombs dropped by the Luftwaffe (German Air Force) to contamination from Allied military activity such as weapons manufacturing or training exercises.<\/p>\n\n\n\nWhile there isn\u2019t any legislation in the UK defining the steps you must take to check for UXO before beginning any construction or development work, there are legal obligations under the Health and Safety at Work Act 1974 and the Construction Design and Management Regulations 2015 to ensure the health and safety of employees. UXO surveys not only ensure the safety of construction workers and the public but also prevent expensive, unexpected costs and delays from disrupting your project further down the line.<\/p>\n\n\n\n
Non-intrusive UXO surveys<\/h2>\n\n\n\n
Efficiently clearing large areas up to 6 metres in depth, non-intrusive UXO surveys are ideal for greenfield sites or areas where ground disturbance must be minimised. Brimstone offers three types of non-intrusive survey: pushcart, towed-array, and drone.<\/p>\n\n\n\n
These surveys excel in pinpointing shallow-buried UXO items, including land service ammunition. They leverage magnetometry to detect ferrous materials, mapping magnetic signatures through fluctuations to identify ferrous objects.<\/p>\n\n\n\n
Pushcart UXO surveys
<\/strong>A pushcart UXO survey is a five-channel system for detecting ferro-magnetic anomalies in small to medium sized areas. This survey is carried out by a specialist two-person team who manually push the system over the area of land being surveyed.<\/p>\n\n\n\nTowed-array UXO surveys
<\/strong>A towed-array UXO survey is an eight-channel gradiometer system that detects ferro-magnetic anomalies in large areas. Again, this survey method is carried out by a specialist two-person team and involves towing the sensors behind an all-terrain vehicle. The wider sensor array increases time efficiency without detriment to resolution or quality.<\/p>\n\n\n\nDrone UXO surveys
<\/strong>A UXO drone survey<\/a> enables us to carry out surveys in areas where a pushcart or towed-array system cannot reach. The UAV is used as a platform for sensors and detectors, enabling our engineers to fly them over extensive areas of land searching for signatures of unexploded ordnance. They are equipped with state-of-the-art Lidar, Photogrammetry and Magnetometry systems which enable precise 3D models to be captured, along with detailed terrain mapping and high-resolution imagery.<\/p>\n\n\n\nOur drone systems routinely deliver superior survey coverage, surveying up to five times as many hectares in a single day compared to the push-cart system. Drone systems are also highly suited to difficult to access areas or areas where ground disturbance must be minimised.<\/p>\n\n\n
