Through BIM-based digital fabrication, designers, builders, and manufacturers of construction materials can perform detailed design and examination of the products to be fabricated as digital objects. Digital fabrication is one such technology developed through the application of BIM and virtual design and construction (VDC) methods in the construction industry. īuilding information modeling (BIM) technology has been rapidly replacing conventional construction models, such as two-dimensional computer-aided design (2D CAD), paper documents, and Excel chart-based schedules, by improving the technical level of construction automation, introducing BIM-based innovations, and application of integrated project delivery (IPD) method in several countries. However, since the BIM concept was introduced in Korea in 2008, efforts have been made to overcome the problem of productivity degradation in the life cycles of construction projects.
Therefore, the cost and time requirements for design, fabrication, and construction of complex types of structures will increase, eventually leading to construction errors and deterioration of building quality. Existing architectural techniques and paradigms are mostly available only in fragments, such as the optimal design technology for complex structures, techniques for fabrication of components, and precise installation technology. These needs have increasingly decided that the buildings be massive and the shapes be more complex thus, the design of free-form and complex elements, manufacture of building components, and construction technology at the site must be supported to meet these needs.
The main trend of the construction industry in the 21st century is the creation of different spaces to improve the quality of human life and in forms that were previously unavailable to meet various user needs.
It is expected that the digital fabrication process and productivity analysis model proposed here will be applied to complex digital fabrication works. In addition, a productivity analysis method based on the queuing model is proposed using personnel input and performance calculation data to verify productivity. This study proposes a BIM-based digital fabrication process for prefabricated parts of buildings. Moreover, an optimized process has not been developed thus far because the productivity of digital fabrication has not been quantitatively verified for various projects in the field. However, the digital fabrication process is inadequate in terms of efficiency and productivity because of the need to convert from conventional two-dimensional (2D) drawings to a BIM design this adversely affects the unified design, fabrication, installation, and inspection processes.

Overall, this study explains the potential lying in renewable energy harvesting in Africa, seeks to emphasize major barriers for implementation of RE projects as well as investigates investment opportunities to implement economically feasible RE projects for cleaner and climate friendly energy future of this continent.Since the concept of building information modeling (BIM) was introduced in South Korea in 2008, digital fabrication concerning free-form shapes and complex parametric information has been expanding owing to the development of BIM software and tools. Students characterize local contexts and identify numerous barriers for deployment of RE systems in Africa. Inputs from local people on how they understand the process of implementing RE projects in Africa might be interesting for investors seeking information about suitable ways for RE project deployment. Useful suggestions formulated directly by young Africans are presented which may contribute to improved risks management when these or other potential RE projects will be deployed. The work provides insights from the local students' perspective for the various stakeholders interested in RE project investments in Africa. Criticalities for the implementation of these projects are discussed in African contexts providing outlook for future investment opportunities in the African continent.
Students' RE projects are assessed with emphasis put on employed business models and project innovativeness. Items of the project investment plan include project synopsis, the sponsors, market analysis and strategy, project scope, regulation and environmental information, project costs, financial projections, business model, and project innovativeness. Pan African University master students were asked by their lecturer to characterize African projects they had in minds in uniform tables. This study provides an overview of potential renewable energy (RE) projects for Africa.
