A management tool to reduce the risk of damage caused by geotechnical groundworks

Abstract

A qualitative risk management tool, developed in the R&D project "BegrensSkade" [1], was recently updated in the R&D "REMEDY"-project [2] to include quantitative risk analysis. The tool contributes to the main objective of REMEDY to reduce the risk of damage to neighbouring structures caused by groundwork, as well as developing practical tools for risk assessment and management for the industry, to aid decision making. The tool is programmed in Visual Basic for Applications (VBA) and implemented in Excel spreadsheet software to emphasize usability among non-experts. The risk methodology implemented in the tool is based on the risk management framework described in the ISO 31000 guidelines [1]. This paper provides a tool overview describing the qualitative and quantitative procedures. The tool has been employed in several projects. The recent upgrades further simplify and improve its use, hopefully also expanding the use amongst project stakeholders. The tool can be downloaded from the project web page: https://www.ngi.no/eng/ProiectsBegrensSkade-II-REMEDY-Risk-Reduction-of-Groundwork-Damage/Risk-management-tools. Currently, only the qualitative procedure has been validated and is available for downloading. The quantitative procedure, after a test period, will be formally released and integrated into the tool.
