TSANG, Po Keung |
Building Information Modelling (BIM) is the 3D virtual model of buildings which embedded information to facilitate the knowledge management and share information with different parties such as architecture, engineering and construction (AEC). In the current stage, BIM is commonly used in design communication, structure and design visualization, clash detection, prefabrication, and 4D simulations. With the complex nature of AEC project, these processes engage multiple parties, professionals and diversified software. In order to effectively support the use of information, facility of an accurate exchange of data among different parties and software is the major concern. The Industry Foundation Classes (IFC) of BuildingSMART, which is standard for interchange of the BIM data in the AEC industry and recognized as methods and tools for project deliver during building life cycle. To extend the uses of BIM for energy analysis, this project shows a feasible approach of extending the IFC standard to satisfy the requirements for energy analysis and introduces an information model and proposes IFC extension to enhance computer aids energy analysis throughout the building life cycle. |

Building Information Modeling (BIM) is an emerging technology applied in Architecture, Engineering and Construction (AEC) industry. With the increase in the BIM application, some legal uncertainties have appeared and led to a high risk in legal aspects when adopting BIM in design and construction projects. It is vital that BIM users should be aware of the potential legal issues and develop suitable legal documents and contracts to prevent these issues from occurring. Within this context, a critical review on different cases associated with BIM is carried out in order to provide an overview of potential legal issues. Model copyright, right of BIM common data environment control and responsible control were discussed. Furthermore, three protocols and guidelines commissioned by the United Kingdom, the United States and Singapore are compared and analyzed. BIM Protocol published by Construction Industry Council of the United Kingdom is suggested as the most comprehensive and structured protocol in the analysis. Recommendations on the aspects of BIM cyber security, practical completion and contractors’ perspective are made to Hong Kong AEC professional institutes to commission a suitable and comprehensive protocol for the local industry. |

Study on BIM Project Execution Plan and BIM Uses in Comparison with PMBOK |
Report |

Ka Wing Ngan HUANG Li |
Project successful strongly relies on PMBOK. Besides that, BIM is important because it is a powerful tool in delivery of BIM-based project. To implement BIM, BIM uses are defined based on project goals. To effective implement BIM as planned, BIM project execution plan (PXP) is necessary to control BIM. In the first section, this paper compares supporting infrastructure from BIM project execution plan (PXP) to PMBOK to find out the relationship. The categories of supporting infrastructure are BIM PXP overview, project information, key project contacts, project goals / BIM uses, organizational roles / staffing, BIM process design, BIM information exchanges, BIM and facility data requirement, collaboration procedures, quality control, technological infrastructure needs, model structure, project deliverables and delivery strategy / contract whereas PMBOK are integration, scope, time, cost, quality, human resources, communication, risk, procurement and stakeholder management. From the investigation, it is found that risk and cost management is not obviously applied from the categories of supporting infrastructure. In the second section, this paper investigate the relationship of various BIM uses in terms of PMBOK. The considerable BIM uses are design authoring, design review, 3D coordination, cost estimation, phase planning (4D Modelling), digital fabrication and site utilization planning. It is also found that scope, communication and human resources management is not obviously applied from the selected BIM uses. In the third section, we recommend that for BIM PXP additional section including project cost management and BIM risk management should be included; and for BIM uses attention should be paid in drafting BIM PXP to support BIM uses and other BIM uses maybe considered. Manager may benefit from the relationship developed and recommendation in BIM implementation. |

The objectives of the project are to identify the risks with high risk level and mitigation with higher effectiveness in BIM industry. The survey was conducted to collect the data of risks and mitigations adopted by different groups of people. Overall analysis, by-group analysis and cross-group analysis were performed.
Thus, the risks were analyzed and discussed with two approaches - level of consequence and level of probability. The level of risk was identified combining these two approaches. The assumption and resolution of identified risks were discussed. Mitigation strategies with higher appropriateness were identified and relevant comments were made.
It is found that the level of risk of C6 (Poor participation / contribution from project team in BIM adoption) and M1 (Lack of adequate expertise in BIM) are extreme, and are very high for risk T6 (Design conflict / clashes in BIM was not revealed / unresolved), C1 (Unclear requirements (e.g. EIR / AIR / contract) of BIM uses and specifications), C2 (Unclear roles, responsibility and liability in BIM implementation). As for mitigation strategy, it is found that mitigation #1 (Clear Employer’s Information Requirement) and #11 (BIM Education for Project Team) were mitigation strategies with the 1st and 2nd ranking in appropriateness/effectiveness. Mitigation can minimize risk C6, and mitigation #11 helps to mitigate risk M1. |

HUANG, Cong ZHOU Haoran LIU Hao |
BIM model is a prerequisite for the Operation and Maintenance (O&M) of sustainable buildings. Only after having a reliable BIM model can start O&M related work, such as space management and energy management, all these works needs to confirm the accuracy of the BIM model. In this project, the author conducted a verify of the BIM model to ensure that the model was correct before the O&M work started. This project first compared various survey methods, and based on their advantages and disadvantages, chose the laser scanning method and manual survey method for experiments. Then using two selected methods to do site surveying for HUKUST parking lot and LTK to SENG Commons. And the end, given survey recommendations for different types of as-built model verification based on the survey result. |

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. |
