Information Technology for Sustainable Infrastructure Construction and Management

基础设施的重要性（如道路、建筑物、工业设施、水、废水、机场等）香港的经济繁荣和生活质素，是一个公认的事实。维持这一基础设施，改善基础设施项目和资产绩效，需要良好的管理和良好的技术基础。加拿大的政策和工业团体已经认识到这一必要性。拟议的研究通过建立和应用信息生成的技术基础及其在可持续基础设施的设计、建设和管理中的使用来解决这一紧迫问题。使这成为一个特别具有挑战性的问题的是：（a）基础设施及其建设的复杂的社会、行为、经济和环境影响，（B）建设项目的动态和背景敏感性，以及（c）传感、通信和信息处理工具的扩散。为了应对这些挑战，拟议的研究有三个目标：（1）通过将基于模型的先验信息、基于证据的推理和数据融合应用于使用3D成像、自动定位、传感和基于网络的系统获取的信息，以改进的频率、准确度和有用性生成信息，可持续供应网络管理、自动化项目诊断和基于项目控制和资产状况指标的决策支持，以及（3）通过重复使用建筑材料、基础设施的系统动力学建模、建筑性能和资产管理指标的开发，了解信息对基础设施可持续性的影响，以及分析实践和技术对业绩和可持续性的影响。这些研究目标直接与国家基础设施系统技术路线图（CIS-TRM），加拿大国家“可持续市政基础设施指南”（CIS-Guide）以及NRC基础设施和建筑环境委员会（BICE）建议等重大举措保持一致。预计研究将对技术进步产生重大影响，例如改进项目和资产状态估计，改进数据融合方法，改进决策支持和管理工具，以及教育和培训新一代研究人员和从业人员。

The importance of infrastructure (e.g. roads, buildings, industrial facilities, water, waste water, airports, etc.) to our economic prosperity and quality of life is a well-accepted fact. Sustaining this infrastructure, and improving infrastructure project and asset performance require good management and a sound technological foundation. Canadian policy and industry groups have recognized this imperative. The proposed research addresses this imperative through creation and application of a technical foundation for information generation and its use in the design, construction and management of sustainable infrastructure. Making this a particularly challenging problem, are: (a) the complex social, behavioural, economic and environmental impacts of infrastructure and its construction, (b) the dynamic and context sensitive nature of construction projects, and (c) the proliferation of sensing, communications, and information processing tools. To address these challenges, the proposed research has three goals: (1) Generation of information with improved frequency, accuracy, and usefulness by applying model based a priori information, evidence based reasoning, and data fusion to information acquired using 3D imaging, automated locating, sensing, and web based systems, (2) Innovative management and use of integrated information systems for improved, sustainable supply network management, automated project diagnostics, and decision support based on project control and asset condition metrics, and (3) Understanding the impact of information on infrastructure sustainability via re-use of construction materials, system dynamics modeling of infrastructure, development of construction performance and asset management metrics, and analysis of the impact of practices and technologies on performance and sustainability. These research goals are directly aligned with major initiatives such as the National Infrastructure Systems Technology Road Map (CIS-TRM), Canada's national "Guide for Sustainable Municipal Infrastructure (Infra-Guide), and the NRC Board on Infrastructure and the Constructed Environment (BICE) recommendations. Significant impacts of the research are expected on technology advances such as improved project and asset state estimation, improved data fusion methods, improved decision support and management tools, as well as education and training of a new generation of researchers and practitioners.
