Virtual office walkthrough using a 3D game engine

Currently, the common method for representing and distributing information about a construction facility to be built is via two-dimensional (2D) drawings and relevant specifications (Figure 1). Recipients of 2D drawings and specifications will extract the necessary information and interpret it based on their previous experience, background and knowledge. Each may have different understanding on how the facility will look like when completed, thus may affect the way the construction process will proceed. The misunderstanding may lead to mistakes which may further lead to additional time and costs. This is the challenge of delivering a facility today.
