Abstract

     A control system is an essential management tool, used to provide real-time (or near real-time) reliable information about project conditions and to alert management when the actual performance does not meet the plan. Data collected by control systems are used as a basis for estimating the actual values of performance indicators, such as schedule, cost, labor productivity, materials consumption, which can then be compared with the planned values. Automation of control processes is capable of significantly increasing reporting frequency, i.e. reduce the time from data collection to reporting a problem, from weeks to days. However, real-time control can only be achieved if data are collected and interpret automatically. This thesis examined the potential of automated monitoring of construction lifting equipment to provide useful feedback information for project management. A preliminary field study confirmed that automated monitoring of lifting equipment is technologically feasible and can provide information about crane’s daily activities in terms measuring of on-hook weight and hook location, measured continuously through time. The monitoring data interpretation process relies on project information stored in a Building Project Model and Knowledge Base. The main principles for automated interpretation of the monitoring data in order to provide managerial information about actual project progress and materials consumption calculations were developed and examined on an actual construction project. A broader field study confirmed that monitoring data can be automatically collected and can be useful in deducing managerial information about project timing and materials consumption.
