TAO Jiali |
Nowadays the construction industry is under pressure to explore effective and efficient techniques and tools to decrease its escalating waste production. Many countries have taken initiatives to reduce the construction and demolition waste. However, the current approaches, techniques and tools focus on separate projects onsite and limited effort is invested to put attention on pre-construction waste generation related to supply chain management issues and procurement, design and tender stages.
Therefore this study aims to develop the BIM-based approaches for C&D waste in the aspect of waste estimation, 3R, prefabrication and clash detection. Besides, this study will also demonstrate and validate the developed approaches for C&D waste minimization using example scenarios. All in all, the application of BIM in C&D waste minimization can be better realized. C&D Waste estimation via the quantity takeoff tool and waste index can clearly show the accurate amount of the waste before the commencement of the works. Classifying the different construction material in BIM model and set up suitable C&D waste management planning definitely improve the efficiency of the waste management. Providing accurate information of precast units ahead of time and assisting the supply chain management can be achieved in BIM model. Visual clash detection reduces rework to some extent. |

BIM is a three-dimensional digital based model or technology with various project-related information inside. It is widely used in modern building industry. As buildings are consuming so much energy today, building energy save has become an important part of a project’s optimization. To achieve the purpose of saving and controlling a building's energy consumption by BIM related software prediction and adjustment and control is a simple and effective strategy.
This project aims to make energy-saving analyzes of STUDENT HALL 7 of HKUST, the main study method is: Revit 3D model—Green Building Studio energy analysis—solar panel analysis—PVGIS analysis—ECOTECT environmental analysis. Firstly obtained the three-dimensional model of Hall 7 through REVIT, and then send the model to Autodesk Green Building Studio to make energy consumption analysis, than make solar panel analysis of the building to find the energy save of panels, afterwards use PVGIS to check if the saving ratio is rational. What’s more, we also import the REVIT into ECOTECT to make further analysis. |

Steel reinforced concrete building structure is very common among Hong Kong. Cost estimation is an important part during the preparation process for a construction project. Nowadays in Hong Kong, the contractor use lots of time in this stage while some mistake may occur as the process is done manually. To reduce error and shorten cost estimation time, design optimization and prefabrication automation leveraging should be considered. This project aims to complete the two objectives by using Building Information Modeling and Dynamo. After the design, the moment envelope generated by ETABS should be extract and input for designing the structural components. When the design of structural component, coding in Dynamo should be able to calculate the construction cost estimation for the building. Construction joint, continuity of rebar and the matching of rebar should be considered and build a bar bending schedule.
This project will go through the reviewing of site solution for solving some common problems. After that, some algorithm will be review to check whether it suitable for solving the problem mathematically. At last, application of graph theory in python 3 is finished and full bin packing algorithm in python is finished for rebar matching to reduce material cost. Suggestion will be made for further study in this project. |

Currently, building information modelling (BIM) technology has been increasingly popular in the architecture, engineering and construction (AEC) industry for some years, but it is not widely adopted in structural design. The objective of this project is to develop a framework for automated rebar design in RC beams using the building information modelling (BIM) technology.
This project presents an automated rebar design program, based on the latest BIM technology. Design constraints for the optimization are considered according to the Hong Kong Code of Practice. The developed program will make use of the analysis result from structural software to design RC beams, and then the tailor-made genetic algorithm will optimize the final rebar design. Finally, generate the rebars to BIM model in 3D environment.
The result shows that BIM can carry out repetitive works and complicated calculations automatically and accurately. Unlike human, they seldom make mistakes through over-tiredness, do not require rest breaks and can carry out in seconds what may take hours to do by manual methods. The overall design process is fully automated, smooth and without error. Therefore, it is anticipated that the time and manpower resource required for structural design and management could be reduced significantly. |

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. |

This project used Building Information Modeling (BIM) and BIM compatible software, Computational Fluid Dynamic (CFD), to analyze the indoor environmental quality of current UG Hall VII building in HKUST under mechanical and natural ventilation. The results obtained from the software analysis were used for evaluating the indoor environment with green building standard BEAM Plus EB Ver. 2 Selective Scheme. Indoor environmental quality analysis and energy analysis on different air-conditioner usage scenarios and modified air-conditioning system were also conducted to investigate whether any modifications could give rise to indoor environment that able to reach BEAM Plus standard while reducing energy consumption. We founded that opening one air-conditioner, with temperature set as 24℃, in only one bedroom in a suite could achieve favourable indoor environment while reducing half of the energy usage on cooling. Also, changing the air-conditioning system from window-type air-conditioners to centralized system could also lower energy consumption on cooling while keeping a comfortable indoor environment. |
