HKUST Analysis of Urban Walkability Using BIM and 3D GIS Models FYP 06/2019 NG, Ho Yin
NG, Sze Wai
Walkability problems are serious issues that influences people’s daily lifestyle. Providing a walkable environment is crucial to maintaining the living standard of people. Therefore, the proposal of Policy Address 2017 from the Hong Kong government has proposed the idea of the development of a walkable city. Kwun Tong was industrialized in an early stage and it was realized that many facilities were not satisfied with the standard of the barrier-free facility so it had undoubtedly been one of the targets. In the past, people analyzed walkability problems using the scoring system, observation or on-site investigation. However these approaches were extremely time-consuming, and were lack of efficiency and effectiveness to tackle the problem. Also, it was difficult to realize both macroscopic and microscopic problems at the same time. Hence, this project aims at dealing with the walkability problems by applying the smart technology, Building Modelling Information Technology (BIM) as well as Graphic Information System (GIS) while this report is mainly focusing on the BIM part at this first developing stage. BIM has been applied in the architecture, engineering and construction (AEC) industry for over a decade but there is less application on the walkability problems in Hong Kong.

The ultimate objective of this project is to enhance and promote the concept of walkability to citizens by applying the policy using smart technology. This project is divided into three stages. The first stage will develop a 3D BIM model of the real district, Tsui Ping North Estate in Kwun Tong. The second stage aims at drawing the 3C line network on the 3D BIM Model so that it can present the walking path of people in different situations. Some selected paths will be used to evaluate its cost and the lowest cost will be considered as the perfect path. In stage three, based on this perfect condition, information will be exported to simulate the walking behavior of people in a different situation. By applying BIM Technology, it can demonstrate the real situation in the computer so as to find out the walking difficulties of people, particularly our targeted group, wheelchair users and the elderly. Likewise, making modifications in the current design, extensions of the walkway or any other possible suggestions will be provided according to the demonstrations so that we can develop a walkable city in the future.

HKUST Automatic Generation of BIM Models Based on Photogrammetry and Laser Scanning Point Cloud Data FYP 06/2019 LEUNG, Chi Ching
SONG, Changhao
As-built drawings are essential to provide information about the most updated configuration of a facility or a structure for project delivery and facility management. Yet, it is stated that approximately 55% of the as-built drawings was found mismatching with the updated configuration of the building, incurring an additional cost of $4.8 billion for verification of the as-built drawings. This paper aims to develop a more advanced method towards automated generation of BIM model using point cloud data from laser scanning based on that developed previously by our research team, reducing labour, cost and time consumed in modelling processes. Geometry information extraction was conducted to each category of the point cloud data with the aim to obtain parameters for automated parametric modelling using Dynamo command networks. The proposed approach was validated by successfully generating as-built Revit models for 3 different sites. N.A.
HKUST Integrating Building Information Modeling and Internet of Things for Building Facility Management FYP 06/2019 CHAN, Sum Chau
DWIVEDY, Sampriti
In Hong Kong’s Smart City Blueprint, promoting ‘Green and Intelligent Buildings, and Energy Efficiency’ is one of the most important initiatives. HKUST, as the leading university in Hong Kong, has been working for years to build a better, smarter and greener campus. Keeping in line with HKUST’s “Sustainable Smart Campus as a Living Lab (SSC)” initiative, this project seeks to enable the Facilities Management Office to make better decisions with respect to balancing the trade-off between human thermal comfort and energy costs. This can be done by optimizing the operational controls of the existing heating, ventilation and air-conditioning systems (HVAC) to the occupancy level of the facility. The research was divided into two case studies, one that focuses on occupancy prediction with the use of machine learning and the other seeks to demonstrate how building information modelling (BIM) and Internet of Things (IoT) can be used to visualize the tradeoff between user thermal comfort and energy costs.

This project also discusses a flowchart to integrate the various technologies being suggested. and identifies certain software tools that can be used to assist in the integration process, for instance Autodesk’s Forge. A web-based graphical user interface for an integrated smart facility management system was also constructed in order to provide a direction for future works on this topic.

HKUST Optimization of Occupant Thermal Comfort and Energy Consumption in HVAC Systems Using a BIM-Supported Computational Approach FYP 06/2019 LUK, Tsz Hin
SIU, Chun Fai
This project aims to analyse thermal comfort and indoor air quality (IAQ) in a lecture theatre where the HVAC system consists of a Variable Air Volume (VAV) system, Displacement Ventilation (DV) system, and Demand Control Ventilation (DCV) system. Based on the simulation result, a strategy is proposed to minimize electricity consumption while maintaining sufficient thermal comfort and indoor air quality to the occupant.

The analysis is conducted using Building Information Modelling (BIM), Computational Fluid Dynamics (CFD) software, and energy simulation software to simulate the airflow, temperature, CO2 concentration and energy consumption in different scenarios. Thermal comfort and IAQ are evaluated by comparing the simulated result to the international standards and local guidelines such as ASHRAE and HKIAQ. Autodesk CFD, Revit, eQUEST and EnergyPlus are used for the simulations in this project.

The simulation result shows that ventilation at the back of the lecture theatre is poor even though the air handling units run in full capacity. This project has found that changing the location of the inlet of supply air duct can significantly improve the ventilation at the back without increasing the electricity consumption. CFD simulation shows that even in 100% occupancy, the lecture theatre after modification fulfils the requirement of an excellent class according to HKIAQ’s objective.

HKUST Incorporating Project Management Techniques in BIM Projects Report 06/2019 Ziwei YU

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.

Building Information Modeling (BIM) is claimed to be as the future trend of the Architectural, Engineering and Construction (AEC) industry and a way to address the issues of AEC. A BIM model can be adopted in different stages of project’s life circle and result in better quality, but less time and cost consumed. Although quality, cost and time are improved by adopting BIM, risk is one of the critical problems in the adoption of BIM. This study is based on conducted surveys and literature research. In this study, risk factors related to BIM adoption were identified and prioritized based on the results of a questionnaire survey distributed to architects, engineering consultants, academics, and construction companies in the AEC industry, followed by a series of discussion on the major risk factors to provide better understanding. The sources were analyzed and used to explain and identify the main risk of BIM related issues. 14 sub-factors of legal risk will be studied and gathered into four big divisions. N.A.
