SafeLane Global's non-intrusive surveys have a wide range of application. The company provides non-intrusive surveys for clients in the UK, Germany and internationally - with non-intrusive surveys available on land and in the marine environment.
They provide clients with cost effective, accurate information about the location and identification of potential anomalies including unexploded ordnance (UXO) threats or hazards that are buried or located within structures.
What is a non-intrusive survey? Let’s take a deeper look
A non-intrusive unexploded ordnance (UXO) survey uses magnetometers to detect ferrous anomalies in the ground – which could be munitions, bombs or other dangerous threats. They are often utilised pre-intrusive construction works such as piling.
A detector is simply walked or driven across the area to be surveyed, so the ground isn’t broken. As a result, non-intrusive surveys are a quick and effective way of surveying a site to identify potential risks.
Land-based non-intrusive surveys work best on greenfield sites. I.e., in locations where there is likely to be less data interference from ferrous objects such as existing piles, or foundations.
Such interference causes background ‘noise’ which makes accurate detection more challenging.
Using the non-intrusive survey method, SafeLane can detect and model items up to 4m below ground level in perfect conditions – and it can detect and model items up to 2m below ground level in a ‘noisy’ area.
If a site is classed as brownfield, it’s unlikely a non-intrusive survey will be successful as previous development works will create too much interference.
Non-intrusive surveys can be useful on expansive projects where shallow intrusive works are planned.
SafeLane is currently conducting non-intrusive surveys ahead of construction for clients in nations as diverse as the UK and Kuwait, Germany and the Falklands.
SafeLane Global has conducted non-intrusive surveys for:
- wind farm projects
- solar farm projects
- pipeline projects
The approach and speed of non-intrusive surveys
Non-intrusive surveys can either be pedestrian (meaning they are carried out by two people walking over the ground with detection equipment) or towed (towing a sensor trailer with an all-terrain vehicle (ATV)). Ground conditions, terrain and the amount of ground that needs to be covered may dictate which method is chosen for your project.
Typically, a pedestrian survey can cover a maximum of 3 hectares per day vs. up to 30 hectares per day for a towed survey.
Ground type obviously plays a large role here, as field boundaries and terrain can impact timelines and what it’s possible to achieve per day.
