Fereshteh Shahmiri and Jeremy Ficca
Pages 1065-1072

In this study a user-friendly model is developed for architects and designers without advanced programming skills who need to operate their projects in a real-time workflow from parametric design to robotic fabrication. Based on the implemented network capabilities in proposed model, not only one but also multiple robotic arms can ...

Cloud-based BIM Data Transmission: Current Status and Challenges

Kereshmeh Afsari, Charles Eastman and Dennis Shelden
Pages 1073-1080

In the architecture, engineering and construction (AEC) industry model-based data exchange methods are mainly based on manual file transfer, data conversion, and data-merge. File-based Building Information Model (BIM) data exchange is either in vendor specific file formats or neutral format using Industry Foundation Classes (IFC). IFC Model View Definitions (MVDs) ...

Development of a modular and integrated product-manufacturing-installation system kit for the automation of the refurbishment process in the research project BERTIM

Kepa Iturralde, Thomas Linner and Thomas Bock
Pages 1081-1089

The manufacture-installation of prefabricated modules for the refurbishment market needs to be lifted to a more integrated, systemized and automated level, in order to transform the existing buildings stock towards near zero energy consumption at reasonable cost. In building renovation, prefabricated modules have to be industrially customized to each building, ...

Lean-based diagnosis and improvement for offsite construction factory manufacturing facilities

Youyi Zhang, Gordon Fan, Zhen Lei, Sanghyeok Han, Claudio Raimondi, Mohamed Al-Hussein and Ahmed Bouferguene
Pages 1090-1098

In current practice, manufacturing companies have daily outputs that are expected to meet the company’s targeted production level. In construction, there is an increasing trend toward buildings being manufactured off-site rather than through traditional stick-built methods on site. This trend has created a demand for construction companies to subcontract work ...
