DT technique plays a key role in sharing information among engineers, project managers, and technicians in different life cycle stages of the buildings, meaning that different stakeholders can communicate technical complexities and arrive at a smart decision, hopefully, improving the sustainability and reducing the risk and cost of the buildings. It is necessary to fully exploit the potential of the state-of-the-art DT technique and integrate it into the existing construction management to enhance the sustainability of the buildings during the whole life cycle. The main aim of this project is to investigate the direction and challenges of the development of digital twin in the construction industry and propose a comprehensive framework on how to integrate DT technology into construction management to enhance life-cycle sustainability. The objectives of the project are: (1) to summarise the recent direction and benefits of DT in the construction industry and investigate the influential factors and barriers to DT adoption in the construction industry from an end-user perspective (2) to design a case study by using a DT application that integrates multi-source data including time schedule, sustainability indexes, and capital costs across the whole lifecycle of the proposed building which aims at enhancing sustainability over the building's lifecycle. (3) to verify the effectiveness of the proposed DT application using the LCA method. Different scenarios (with/without DT) would be assessed using software, hopefully, leading to the demonstration of the superiority of the application of DT in sustainable construction during the life cycle. (4) to propose a comprehensive framework on how to integrate DT technology into construction management to enhance life-cycle sustainability. This project aims at designing a DT model for the proposed building, a comprehensive LCA method for sustainability assessment and mapping a framework of DT application in construction management. Four principal areas would be: (1) Creating a DT model. (2) Proposing an LCA method for the sustainability assessment of the building. (3) Conducting a comparative LCA of different construction scenarios. (4) Mapping a comprehensive framework on the DT application in construction management.

DT技术在建筑不同生命周期阶段的工程师、项目经理和技术人员之间共享信息方面发挥着关键作用，这意味着不同的利益相关者可以沟通技术复杂性并做出明智的决策，有望提高建筑的可持续性，降低建筑的风险和成本。有必要充分挖掘最先进的DT技术的潜力，并将其整合到现有的施工管理中，以增强建筑物在整个生命周期中的可持续性。该项目的主要目的是研究数字孪生技术在建筑业发展的方向和挑战，并就如何将DT技术集成到施工管理中以增强生命周期的可持续性提出一个全面的框架。该项目的目标是：(1)总结DT在建筑业中的最新发展方向和好处，并从最终用户的角度调查建筑业采用DT的影响因素和障碍。(2)通过使用DT应用程序设计一个案例研究，该应用程序集成了拟议建筑整个生命周期的多源数据，包括时间进度、可持续性指数和资本成本，旨在增强建筑物整个生命周期的可持续性。(3)使用生命周期评价方法验证所提出的DT应用的有效性。将使用软件评估不同的方案(有或没有DT)，希望能够证明DT在整个生命周期内应用于可持续建筑的优越性。(4)就如何将DT技术融入建筑管理，以提高生命周期的可持续性提出一个全面的框架。本项目旨在为拟建建筑设计一个DT模型，一种全面的可持续发展评估的生命周期评价方法，并绘制DT在建筑管理中的应用框架。四个主要领域将是：(1)创建DT模型。(2)提出了建筑可持续性评价的生命周期评价方法。(3)进行不同施工方案的LCA比较。(4)绘制了DT在施工管理中应用的综合框架。
