NTS is a thorough investigation of new or previously recorded Suspect Hazardous Areas (SHA). A non-technical survey should be the starting point for recording hazardous areas as Confirmed Hazardous Areas (CHA). However, experience has proven that a large number of SHA and large areas of many CHA are, in fact, hazard free when cleared. As a result, stakeholders are increasingly aware of the requirement to eliminate the “suspicion” from these SHA using methods other than conducting full clearance.

Suspicion can be removed through the process of collecting and analysing existing and new information regarding a claim. Ideally, through proper non-technical survey procedures BDMS will ensure that only confirmed and accurate information will be recorded. This will assist in the planning of further survey (technical survey) if required, or assist in targeting more accurately defined areas for full clearance. Non-technical survey may be a stand-alone activity, but normally complements the technical survey process.

Non-technical survey is only to be undertaken by technically qualified personnel who collect essential information about a SHA in order to allow a decision to be made as to what further actions are to be taken with regard to the SHA. Non-technical survey activities can vary from analysis of existing information, to visits and meetings with local landowners and/or authorities. Normally there is no need to enter the SHA while conducting a non-technical survey.
