Abstract
Abstract: Good design and construction planning are essential to ensure the quality of the final product. To do this, it is necessary to develop an integrated organizational system for production and work schedule control, just in time material delivery, job site layout planning and real-time task management. The main objective of this work is to propose a method to improve process flow planning of prefabricated concrete panels based on the software application that uses Visilean® to monitor the movement of the parts in the factory. Visilean® model was useful for the visual verification of project, production and installation processes allowing suggestions for improvements to operational procedures. Research’s contribution is to propose a method for integrated planning that favors scenarios creation to anticipate possible problems that usually occur in both production flow and information flow. In practice, the researchers created a simple interface that allows operators to visualize times, production services and their sequence in real-time. Better visualization of the processes and control has a great impact on the final product’s quality, as well as, timely delivery and improved communication between project, production and construction teams. For future research, the inclusion of the Internet of Things for process automation will be an essential complement to the model.
Highlights
The purpose of the prefabricated industry is rapid assembly due to the pre-fabrication of components
Problems related to the planning of construction logistics operations, especially information flows, materials, people and space can be classified into three dimensions of sustainability: economic, environmental and social (Bhattacharjee et al, 2016)
The 3D model in IFC format (Revit) of the shed was provided by the company as can be seen in Figure 5, as well as the 2D plan, the sections, the number of panels, the location of each panel, and the characteristics of each panel
Summary
The purpose of the prefabricated industry is rapid assembly due to the pre-fabrication of components. Problems related to the planning of construction logistics operations, especially information flows, materials, people and space can be classified into three dimensions of sustainability: economic, environmental and social (Bhattacharjee et al, 2016). The economic dimension is the unnecessary cost due to the rework of poorly planned projects. This problem gives rise to the environmental dimension, which consists of the waste of material needed to redo the work and, the increase of construction work hours. The increase in working hours increases the chance of accidents related to occupational hazards since workers are more exposed in the workplace, which is the social dimension. The deficiency in the flow of information is the source of the problems. When planning is not communicated clearly and continuously with each change it generates all the problems mentioned above resulting in late delivery and loss of money
