HKUST | Identifying potential opportunities of building information modeling for construction and demolition waste management and minimization | Journal | 03/2017 | Won, J., and Cheng, J.C.P. | The amount of waste generated in construction and demolition (C&D) processes is enormous. Therefore, many studies on efficient C&D waste minimization and management have been conducted. However, 21 process-related and 8 technology-related limitations in C&D waste management and minimization have not yet been resolved. Building information modeling (BIM) helps project participants improve the processes and technologies in the planning, design, construction, and demolition phases, thereby managing and minimizing C&D waste efficiently. Therefore, this paper identifies the potential opportunities of BIM for efficient C&D waste management and minimization, such as design review, 3D coordination, quantity take-off, phase planning, site utilization planning, construction system design, digital fabrication, and 3D control and planning. The BIM-based approaches can support C&D waste management and minimization processes and technologies by addressing existing limitations through in-depth literature review. The roles of project participants and information required for each BIM-based approach in C&D waste management and minimization are discussed with illustrative process maps. | 連結 |
HKUST | Quantification of construction and demolition waste prevented by BIM-based design validation: Case studies in South Korea | Journal | 01/2016 | Won, J., Cheng, J.C.P., and Lee, G. | Waste generated in construction and demolition processes comprised around 50% of the solid waste in South Korea in 2013. Many cases show that design validation based on building information modeling (BIM) is an effective means to reduce the amount of construction waste since construction waste is mainly generated due to improper design and unexpected changes in the design and construction phases. However, the amount of construction waste that could be avoided by adopting BIM-based design validation has been unknown. This paper aims to estimate the amount of construction waste prevented by a BIM-based design validation process based on the amount of construction waste that might be generated due to design errors. Two project cases in South Korea were studied in this paper, with 381 and 136 design errors detected, respectively during the BIM-based design validation. Each design error was categorized according to its cause and the likelihood of detection before construction. The case studies show that BIM-based design validation could prevent 4.3–15.2% of construction waste that might have been generated without using BIM. | 連結 |
HKUST | Construction Planning of Prefabricated Units Leveraging BIM and Resource Leveling Techniques | FYP | 06/2018 | WONG, Kok Yiu YEUNG, Ching Hei |
As a compact city with limited amount of available land and vast population, Hong Kong is currently facing the massive demand for housing. This phenomenon has been driving the construction industry to enhance the productivity of construction projects, particularly for residential buildings. In recent years, the Hong Kong government has been investigating the feasibility of Modular Integrated Construction (MIC). MIC refers to a construction method where volumetric modules are prefabricated in factories and then assembled at a construction site to form a building. The productivity of this method has been demonstrated by numerous projects in foreign countries, such as Singapore and China. In view of the proven benefits of MIC, the Hong Kong government has proposed three pilot projects recently, which will adopt MIC to construct resident buildings. However, the local industry possesses insufficient experience in managing this kind of construction projects. This report presents an optimization framework, which integrates Genetic Algorithm (GA) and Building Information Modeling (BIM) to perform resource leveling based on constraints of a MIC project. An illustrative case demonstrates the functionalities of GA and BIM in optimizing the schedule of a MIC project. The proposed framework aims to provide the industry practitioners with a general guideline for scheduling a MIC project. | N.A. |
HKUST | Natural-language-based intelligent retrieval engine for BIM object database | Journal | 03/2019 | Wu, S., Shen, Q., Deng, Y., and Cheng, J.C.P. | Rapid growth of building components in the BIM object database increases the difficulty of the efficient query of components that users require. Retrieval technology such as Autodesk Seek in America and BIMobject in Europe, which are widely used in BIM databases, are unable to understand what the search field truly means, causing a lack of completion and a low accuracy rate for results incapable of meeting the demands of users. To tackle such a problem, this paper puts forward a natural-language-based intelligent retrieval engine for the BIM object database and Revit modeling. First, a domain ontology is constructed for semantic understanding, and the BIM object database framework is established for testing our search engine. Second, “target keyword” and “restriction sequence” proposed are extracted from the natural sentences of users. Then, a final query is formed, combining concepts of “keyword” and “restriction sequence”, and its concepts are expanded through the semantic relationship in ontology. Finally, the results are presented after mapping from the final query to the BIM object database and ranking of results. Compared with traditional keyword-based methods, the experimental results demonstrate that our method outperforms the traditional methods. | 連結 |
HKUST | Comparative Study on Global BIM Standards | Report | 06/2019 | Xiaoyang TANG | In the recent decade, the Building Information Model (BIM) is developing at an unbelievable high speed worldwide. Just two years ago, China has published its first BIM standard to unify the BIM project process. In this essay, several China BIM standards including GB/T 51269, GB/T 51212 and GB/T 51301 are compared with other released global BIM standards according to its category. Mainly, there are three types of standards in the world, which are the International Framework for Dictionaries (IFD), Information Delivery Manual (IDM) and Industry Foundation Class (IFC). First, two types of standards are focused, which IFD will compare the GB/T 51269 with OmniClass from America, while IDM will compare the GB/T 51212 and GB/T 51301 with CIC BIM standard from Hong Kong, Singapore BIM Guide Version 2 and PAS 1192.2 from the UK. In order to compare these standards with a logic method, CIC BIM standard’s structure is chosen as the example for IDM while IFC follows GB/T. All the sections mentioned in the standards have been compared to summarize the advantages and disadvantages of China BIM standards. After compared all the standards, it could conclude that the GB/T standards are general information for most sections, which means it is suitable for most types of BIM projects. However, several sections are missing compared with other global BIM standards. For example, one of the most important BIM section called Individual Discipline Modelling is missing in any GB/T standards. Therefore, there is still room for improvement in the future. |
