The difficulties of undertaking geospatial surveys, particularly in unstable buildings or underground environments, are well documented. However, the pressure to collect accurate, real-time data within strict timelines has certainly intensified in recent years. With increasingly tight deadlines coupled with strict budgets, conducting surveys of hard-to-access sites can be a real challenge for engineering and construction firms. This article explains how new innovations in building information modelling (BIM) are providing an answer with the aid of simultaneous localisation and mapping (SLAM) technology. As engineering and construction firms grapple with issues such as skills shortages, robust safety regulations and fierce competition for contracts,...
