Minimizing Risk and Uncertainties in Construction Projects

Abstract

The difficulty of managing the individual flows in the construction process is mostly due to unpredictable conditions, scheduling pressures and the large amount parts involved. This approach analyses how uncertainties and risk are created and how they can be managed by the means of Building Information Modelling and Lean Construction principles.

Building Information Modelling (BIM) technology has been integrated in architecture and engineering since the past three decades, but it is nowadays when the use of BIM is crucial for to minimize risks and comply with the program. Although the most common use of BIM is the organization of the large amount of information connected to the project, it is also used for visualization, building design and clash detection. One of the concepts that more effectiveness has demonstrated in the management of construction projects is the concept of Lean. The idea of Lean is to eliminate what does not add value from the perspective of the customer. In this analysis, the implications and consequences that the use of BIM has in Lean Construction are assessed.

In addition, it is essential to improve the projects management by identifying the risks, planning responses and coordinating the information flow and the resources. In order to give the widest range of solutions to this, other important concepts are evaluated, such as the TFV-model (transformation, flow and value), the last planner system and the location-based scheduling; concepts used to mitigate the possible damage inflicted by unexpected situations.
