Integrating building information models with construction process simulations for project scheduling support

A distributed multi-model-based Management Information System for simulation and decision-making on construction projects

Traditional construction planning, which depends on historical data and heuristic modification, prevents the integration of managerial details such as productivity dynamics Specifically, the distance between planning and execution brings cost overruns and duration extensions To minimize variations, this research presents a Building Information Modeling (BIM)-integrated simulation framework for predicting productivity dynamics at the construction planning phase To develop this framework, we examined critical factors affecting productivity at the operational level, and then forecast the productivity dynamics The resulting plan includes specific commands for retrieving the required information from BIM and executing operation simulations It consists of the following steps: (1) preparing a BIM model to produce input data; (2) composing a construction simulation at the operational level; and (3) obtaining productivity dynamics from the BIM-integrated simulation To validate our framework, we applied it to a structural steel model; this was due to the significance of steel erections By integrating BIM with construction operation simulations, we were able to create reliable construction plans that adapted to project changes Our results show that the developed framework facilitates the reliable prediction of productivity dynamics, and can contribute to improved schedule reliability, optimized resource allocation, cost savings associated with buffers, and reduced material waste

BIM-Integrated Construction Operation Simulation for Just-In-Time Production Management

Waste in the construction industry has been the subject of several research projects around the world in recent years. Researchers implement different methods to reduce the amount of waste in the construction industry. One of the effective methods for reducing waste is the application of lean approaches. Lean construction is a result of the introduction of a new form of production management. Although lean construction is still evolving, its generic principles, techniques and tools can already be applied. Waste reduction is one of the basic concepts of lean thinking. In general, project managers tend to conceptualise 'waste' as physical construction waste, but lean thinking believes that there are noticeable wastes hidden in construction processes (such as non-value-adding activities and waiting time). We aim at examining the ability of lean construction principles to reduce construction process waste through a case study (reinforcement process). Computer simulation is utilised to reveal the results of lean principles application prior to
