HKUST	Automated quality assessment of precast concrete elements with geometry irregularities using terrestrial laser scanning	Journal	04/2016	Wang, Q., Kim, M.-K., Cheng, J.C.P., and Sohn, H.	Precast concrete elements are popularly used and it is important to ensure that the dimensions of individual elements conforms to design codes. However, the current quality assessment of precast concrete elements is inaccurate and time-consuming. To address the problems, this study presents an automated quality assessment technique which estimates the dimensions of precast concrete elements with geometry irregularities using terrestrial laser scanners (TLS). While the scan data obtained from TLS represent the as-built condition of an element, a Building Information Modeling (BIM) model stores the as-design condition of the element. Taking the BIM model as a reference, the scan data are processed to estimate the as-built dimensions of the element. Experiments on a specimen demonstrated that the proposed technique can estimate the dimensions of elements effectively and accurately. Furthermore, a mirror-aided scanning approach, which aims to achieve reduced incident angles in real scanning environments, is proposed and validated by experiments.	Link
HKUST	Mapping between BIM and 3D GIS in different levels of detail using schema mediation and instance comparison	Journal	04/2016	Deng, Y., Cheng, J.C.P., and Anumba, C.J.	The Building Information Modeling (BIM) domain and the Geographic Information System (GIS) domain share a mutual need for information from each other. Information from GIS can facilitate BIM applications such as site selection and onsite material layout, while BIM models could help generate detailed models in GIS and achieve better utility management. The mapping between the key schemas in the BIM domain and the GIS domain is the most critical step towards interoperability between the two domains. In this study, Industry Foundation Classes (IFC) and City Geography Markup Language (CityGML) were chosen as the key schemas due to their wide applications in the BIM domain and the GIS domain, respectively. We used an instance-based method to generate the mapping rules between IFC and CityGML based on the inspection of entities representing the same component in the same model. It ensures accurate mapping between the two schemas. The transformation of coordinate systems and geometry are two major issues addressed in the instance-based method. Considering the difference in schema structure and information richness between the two schemas, a reference ontology called Semantic City Model was developed and an instance-based method was adopted. The Semantic City Model captures all the relevant information from BIM models and GIS models during the mapping process. Since CityGML is defined in five levels of detail (LoD), the harmonization among LoDs in CityGML was also developed in order to complete the mapping. The test results show that the developed framework can achieve automatic data mapping between IFC and CityGML in different LoDs. Furthermore, the developed Semantic City Model is extensible and can be the basis for other schema mappings between the BIM domain and the GIS domain.	Link
HKUST	Analytical review and evaluation of civil information modelling (CIM)	Journal	04/2016	Cheng, J.C.P., Lu, Q., and Deng, Y.	Building information modeling (BIM) has been widely adopted in the building industry. However, the use of BIM in civil infrastructure facilities, sometimes referred to as civil information modeling (CIM) has been slow in its application. Industry and academia are increasingly putting effort into CIM study and implementation, but so far there has been no comprehensive review of their effort in this regard. This paper presents a framework to evaluate the current practices of CIM adoption for various civil infrastructure facilities. In this study, civil infrastructure facilities were divided into nine categories for evaluation and the effort with regard to CIM adoption for each civil infrastructure category was evaluated in six aspects. Based on the evaluation and comparison results of 171 case studies and 62 academic papers on CIM, research gaps were identified and recommendations were made. For example, the findings show that data schema development for civil infrastructure facilities other than bridges, roads, and tunnels are lacking. The results and research gaps revealed by this study are useful for both researchers and practitioners.	Link
HKUST	Developing a Building Information Modeling Framework for Infrastructure Facility Management	FYP	06/2016	LI, Kang TANG, Chung Hin	Building information modeling (BIM) aims to facilitate information management and collaboration among stakeholders in different domains over the building facility life cycle. In a BIM model, each building component has its properties, information, and semantics. Modifications performed in one view will be reflected in all perspectives. BIM models are increasingly used in the building industry as an object-based information hub for storing, integrating and managing building information in different aspects throughout the design, construction, and maintenance operations. However, the applications of BIM for civil infrastructures are still immature and uncommon. This project aims to develop a BIM-based framework that facilitates the facility operation and management process of civil infrastructure facilities. In this project, the information requirement and facility management process will be studied and summarized. A semantic data model and system framework for infrastructure facility management will then be developed. The developed framework will finally be illustrated and validated in case scenarios.	N.A.
HKUST	Analysis and Evaluation of Green Building Features Using Building Information Modeling	FYP	06/2016	KEUNG, Wun Ting Iris WONG, Wing Man	There is a global trend of green buildings in recent years. As of 2011, there are over 10,000 green building projects certified by the LEED (Leadership in Energy and Environmental Design) standard in the United States alone. In Hong Kong, the BEAM Plus green building standard developed by the Hong Kong Green Building Council (HKGBC) in 2009 has certified over 200 projects in Hong Kong. Green buildings utilize various design features and operation technologies to reduce energy and water consumption, improve indoor environmental quality and increase building performance. This project aims to study the common green building features and evaluate them using building information modeling (BIM) and computer simulation techniques. In a BIM model, each building component has its properties, information and semantics, which support sophisticated simulation and analysis under different conditions. In this project, commonly adopted energy saving and indoor environmental quality improvement green building features will be modeled, evaluated, and compared.	N.A.
