HKUST | Incorporating Project Management Techniques in BIM Projects | Report | 06/2019 | Ziwei YU Luo Yanfang |
In order to manage a project seamlessly, there is a need to establish effective communication between different departments and identify the risks in the project, determine the affected or influencing stakeholders, provide timely resources and logistics, and manage the available resources to make a framework for project implementation. There are several standards and one of the most recognized standards is the Project Management Knowledge Facility (PMBOK). PMBOK is not just a guideline and a methodology for project management, but also can help projects for professional, targeted and comprehensive management. Building Information Modeling (BIM), a project management methodology has been adopted in recent years to design a project integrated as a 3-D information model, which adds all project information in the various phases of the project to a 3-D information model. For a correct BIM implementation in a project, BIM must be integrated into the overall management of the project and must have a BIM Execution Plan (BEP) adapted to the needs of the client and which in turn is integrated into the project management plan. To review BIM/BEP and project management comprehensively, this research consists of three main stages: (1) select of target database examining both academic and applied publications to analyses the situation between BIM/BEP and PMBOK; (2) conducts two surveys about “BIM/BEP with PMBOK” and “BIM project with Risk Management” to have deep understanding of the industry status; (3)select integration, stakeholder and risk management as specific aspects to analyze, and develop a preliminary framework of process guide for BEP. | N.A. |
HKUST | Construction Lift Planning for Prefabricated Units Based on Building Information Modelng and Optimization Techniques | FYP | 06/2017 | LEE, Hoi Yin LO, Kwong Ching |
In recent years, prefabricated construction has been increasingly employed in building projects, especially in vertical extension of existing building. However, current lift planning mainly relies on experience and instinct of site manager, leading to potentially poor lifting schedule that may incur extra time and costs on lifting operations. This project presents a BIM-based lift planning framework for prefabricated modules in vertical extension project that aims to optimize the lifting schedule of prefabricated modules and provide visualization for actual lifting path of the modules. The framework considers three main models: (1) information extraction and geometry simplification model to obtain the module information and simplify the shape of modules, (2) analysis model to calculate the actual lifting path distance of each prefabricated module, and (3) optimization model for the selection of ideal lifting schedule using genetic algorithm (GA). An illustrative example is presented to illustrate and evaluate the proposed framework. The results show that the proposed framework can generate the shortest lifting path for each prefabricated module automatically. The lift planning for prefabricated modules in vertical extension project can be significantly improved by the developed framework. | N.A. |
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. |

HKUST | BIM Model Reconstruction and Checking Using 3D Laser Scanning and Machine Learning Techniques | Report | 06/2020 | LEI Ian Wang IEONG Kuan Pui |
In this project, the semantic segmentation performance of the deep learning model PointNet on Mechanical, electrical and Plumbing (MEP) is studied. Then, data of different similarity is used to test the model and the experiment of the mechanism of PointNet is conduct. Moreover, this project aims to evaluate the feasibility of generating a generalized model for semantic segmentation of MEP based on our own MEP point cloud data. On the other hand, the data preprocessing procedure is introduced. Finally, discussion about the result and conclusion are made. | N.A. |
HKUST | Developing a BIM-Based Facility Management Framework for Building Operations | Report | 06/2017 | Zhang Zhongkuang Xin XIA |
Indoor air quality affects human comfort in several aspects such as temperature, humidity, CO2 and CO. With BIM and sensor technologies, the real-time indoor air quality data can be collected by sensors, transmitted and displayed in the BIM model, therefore the building control system can make appropriate adjustments to improve the indoor air quality. For BIM models, the model-based approach increases efficiency within individual organizations and truly shines during coordinated project delivery. Building information modeling can drive time and budget savings for building and infrastructure projects. For sensors, the data gathered is converted to a digital form and is processed at high speed. Sensor technology can store the data in memory, from where it can be retrieved later for processing, analysis and presentation. In this research, a plugin for grading the indoor air quality was designed, which can grade the indoor air quality at current or a specified past time as “good”, “fair” or “bad” showing in the BIM model. With the grading level, proper regulate and control could be made from the building control system to improve the indoor air quality. This designed plugin was used in a real case of seafront sport center in HKUST. Moreover, to efficiently manage sensors in a building, to reduce the energy consumption thus reduce the budget, linking facility and energy management to human comfort are also necessary and should be completed in the future work. |

HKUST | Multi-zone indoor CFD under limited information: An approach coupling solar analysis and BIM for improved accuracy | Journal | 10/2020 | Kwok, H.H.L., Cheng, J.C.P., Li, A.T.Y., Tong, J.C.K., and Lau, A.K.H. | It is important to monitor the indoor air quality and thermal comfort of an office environment for the wellbeing of its occupants, and, to do so, computational fluid dynamics simulation is more cost-effective than measuring an entire floor. Computational fluid dynamics simulation has been used by previous studies for single rooms and partitioned spaces, but not for office floors with multi-zone ventilation systems, and air infiltrations between different zones through closed doors have been neglected. Also, since it is often not possible to take measurements across an entire floor due to concerns of tenant privacy, few studies have used the limited obtainable field measurements to validate multi-zone computational fluid dynamics simulations. This study describes a methodology to conduct indoor multi-zone steady-state computational fluid dynamics simulation, with improved accuracy, on a typical office floor where there is limited information on carbon dioxide concentrations and temperatures. Heat and mass conservation equations were used to compensate for the lack of information. The mechanical ventilation and air conditioning layout was considered along with the sources of heat and carbon dioxide emissions. To improve the accuracy of the simulation on temperature, a solar analysis, based on building geometry, orientation, materials, location, and weather, was conducted to estimate any solar heat gain and distribution through curtain walls. Building information modeling supported the solar analysis and provided geometric information for the computational fluid dynamics simulation. The methodology was validated by a real case of a commercial building, where the accuracy of the temperature simulation improved by 9.9%. | 连结 |
