Before breaking the surface the contractors and crews need to do a KLIC request for information. The relevant utility owners provide information about the existing underground networks for the specific location(s). Since several of these networks go back a long time, the actual location may not match with the provided location data. The check the accuracy of the provided information, and the inspection of the actual condition often one or more test trenches are dug. While test trenches provide vital information the digging and inspection of these test trenches takes time and effort and may even introduce added hindrances and risks. Selection of number and location(s) therefore always requires trade-offs and compromises. Although digging of test trenches is common practice the reasoning regarding location(s) is mostly implicit, unclear and not documented. The random choice causes many damages to underground systems (35000 damages to Dutch underground system in year 2015). The reliable decision process must be designed according to environmental, safety, management and economic aspects, which are the main areas where a damage in the excavation process will have consequences. Therefore I have developed the Decision Support System (DSS) to determine suitable location to dig test trenches. Designed DSS assists decision-makers in data collection, data storing, data analysis, careful risk assessment, test trench location and decision-making procedure reporting.
