Design and validation of the first phase of the new chronographical standard protocol for construction project scheduling Ardila, Fabian A.; Francis, Adel
Graphical modeling is considered to be a suitable approach for displaying project data because of its ability to communicate information clearly and effectively through graphic means such as shapes, connectors, colours and textures. However, current methods and software do not propose a standard protocol for the graphical representation of the scheduling. Little research has been undertaken in this area and therefore, it has been up to the individual planner to set his or her own standard. We have developed the first phase of a new standard protocol for construction project scheduling compatible with Chronographical Modeling. This first phase consists of the development and validation of a graphic convention including textures and colours. The present paper discusses the validation phase of this convention. Its main objective is to validate a range of textures that represent the construction activities. This validation was performed through a case study with the participation of 15 planners, as well as graduate and undergraduate students. It consists of several tests including the application of the various textures of the proposed convention to a building scheduling. The results of the case study were used to assess the suitability of the protocol and its visual clarity while simultaneously seeking to diminish the mental effort necessary for finding information. Future phases are designed to integrate other graphic elements to the protocol, such as shapes, symbols and codes.
