Abstract

The construction of a building has been traditionally supported on the timeline schedules of the construction activities established in each case, and on technical drawings of the project. A prototype based on virtual reality (VR) technology with application to construction planning, was implemented. This interactive virtual model intends to present the project in a three-dimensional (3D) way, connected to construction planning schedule, resulting in a valuable asset in monitoring the development of the construction activity, based on the construction planning designed. The 4D application considers the time factor showing the 3D geometry of the distinct steps of the construction activity, according to the plan establish to the construction. The 4D model offers a detailed analysis of the construction project. Additionally, VR technology is used and presented as an innovative visual tool. It allows the visualization of different stages of the construction and the interaction with the construction activity. This application clearly shows the constructive process, avoiding inaccuracies and building errors, and so improving the communication between partners in the construction process. This tool is an important support in project conception and application.

Key words: Virtual reality, 4D models, construction planning.
