This project reviews some of the existing Indoor positioning system (IPS) and finds that Wi-Fi would be a suitable choice to be incorporated with Building Information Modelling (BIM) for the purpose of facility management. Indoor localization and finding of the shortest path are two major aspects which could combine with facility management and this project is going to investigate into them.
As Wi-Fi positioning is controlled by some factors like k-means clustering and the number of fingerprints, an experiment was conducted to see how these factors would affect the accuracy of indoor localization. The result would be discussed also. In an experiment of finding the shortest path, visibility graph and Dijkstra algorithm are two techniques used for path-generation and path-finding respectively. They would be written as codes and implemented into a mobile App. The App would be the product to test the above experiments and East Point City, which is a shopping mall, would be the chosen for the field test.
The simulation of the interaction between building management system and pathfinding system android devices was carried out successfully, which reveals the high possibility of the application of BIM on indoor navigation system for the purpose of facility management, which could potential enhance human productivity. |

Seismic capacity of an underground urban transportation hub becomes essential to reduce the risk of seismic hazards. By conducting a comprehensive seismic analysis, it is possible to predict the seismic hazard of the transportation hub more accurately. However, seismic design for the transportation hub is of importance to analyze the soil-structure interaction effect. Therefore, Kowloon Station is selected as a testbed to demonstrate whether the SSI effect is beneficial or detrimental. Today Building Information Modelling becomes a powerful tool to develop a three-dimensional digital model such that it can act as a database for further seismic analysis. Since the numerical finite element modelling method is a common approach to solve the problem, in this study, Plaxis 3D, a professional geotechnical FEM software, is selected to investigate the SSI effect on Kowloon Station. Advanced material models are provided to deal with the complexity of the problem.
The results show that the SSI effect has a beneficial effect which the peak acceleration of the structure base is smaller than that at the ground surface. To carry out a more realistic simulation, more laboratory tests should be carried out to obtain the dynamic soil properties. In order to examine the damage to structural and non-structural components of the structure, the recorded PGA can be applied in further studies such as fragility curves so as to analyze probability of the damage. |

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. |

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. |

The sustainability of an infrastructure is of paramount importance to protect the benefits of both clients, engineers and its end-users. Building Information Modelling (BIM) therefore has become a vital tool for facility management (FM) to monitor the lifecycle of all building elements. Numerous of frameworks in the industry, however, are unable to locate and trace the asset information details of the building elements automatically for the asset management(AM) in the building lifecycle, especially the operation and maintenance stage. These existing frameworks highly rely on facility managers to locate the building elements and filter the information from a humongous database and carry out further data analysis for asset management strategies plan. Therefore, developing an integrated BIM framework to integrate the use of Radio Frequency Identification (RFID) technology and a FM software is essential for a more advanced facility management, especially the asset management performance of an infrastructure.
In this research, AM is focused and a BIM model of the HKUST library is established as our targeted infrastructure for framework scenario establishment. Numbers of RFID tags have been installed on various library assets to collect respective RFID elements data. A Structured Query Language (SQL) database has been created to store in MySQL and integrate the data of the RFID tags with a FM software, Archibus. A RFID Asset Management website has been established to filter and visualize the required data. Finally, a BIM-based framework for asset management has been attained. The research framework has been applied to a HKUST Library-based AM scenario and the results have proved its AM functions and reliability in enhancing the AM performance of an infrastructure. |

With the global popularization of smartphones, which are equipped with various electronic sensors and hardware, the smartphones can collect useful information, such as location, light intensity, speed from the surroundings almost everywhere and anytime. The instant availability of the useful information has led to the formulation of a novel concept called context-awareness, which is developing computer programs to perform specific functions based on the acquired information. Location-awareness, which focuses only on collecting location information, is one of the future trends for building information modelling (BIM) development. The primary purpose of this project is to incorporate the idea of location-awareness to BIM in construction management and monitoring. To achieve this purpose, this project is objected to accomplish three main objectives, which are locating and analyzing the user current indoor position, acquiring and transferring the information in from BIM models to local devices and establishing the location-aware BIM framework on a viable and convenient platform. Thus, the location-aware BIM framework is developed as a mobile application named as “HKUST Library Helper”. The mobile application is not only equipped with Wi-Fi fingerprinting technology to support indoor localization, but also it is designed to provide different useful functions such as identifying rooms based on user position or by touch, extracting room information and creating and retrieving special notes and tasks for different rooms. |
