4DCAD‐Safety: visualizing project scheduling and safety planning Available to Purchase

Safety planning in construction project management is separated from other planning functions, such as scheduling. This separation creates difficulties for safety engineers to analyse what, when, why and where safety measures are needed for preventing accidents. Another problem occurs due to the conventional practice of representing project designs using two‐dimensional (2D) drawings. In this practice, an engineer has to convert the 2D drawings into three‐dimensional (3D) mental pictures which is a tedious task. Since this conversion is already difficult, combining these 2D drawings with safety plans increases the difficulty. In order to address the problems, 4DCAD‐Safety is proposed. This paper discusses the design and development of 4DCAD‐Safety application and testing its usefulness in terms of assisting users in analysing what, when, where and why safety measures are needed.
