Towards collection, processing and use of actual data for process simulation during construction

Construction projects in urban areas imply multiple activities on limited work space and hence lead to interferences and delays depending on the quality of the planning. Due to the increasing competition in construction industry an immediate reaction to these problems is crucial. This paper introduces a comprehensive approach for construction planning utilizing process simulation and VR-visualization to address the issues mentioned. By monitoring the construction progress actual state data is generated to update simulation parameters and corresponding results for future construction realization. Therefore a detailed concept was developed to process the various types of raw (actual) data in order to receive information about the construction progress. Furthermore this paper introduces a design for simulation and visualization environments to interpret actual data. Hence temporal and spatial collisions can be detected before execution and profound measures taken respectively. 1. Introduction an
