Many construction projects are not systematically monitored, due to the difficulty in gathering reliable information to assess the progress of ongoing construction work. Productivity assessment requires manual data collection, which is carried out by employing observers to collect worker Tool Time and performance information from sites. The quality of such manually collected data is low, due to human errors and limitations in data availability. Several researchers have attempted to solve this problem by automating the monitoring of various aspects of construction projects. However, the industry still lacks a comprehensive solution that can facilitate progress monitoring of a construction project in its entirety. The goal of the proposed research is the development of an automatic, real-time system that can handle this diversity and complexity and can, therefore, provide an optimal solution for the problem of progress monitoring for building construction projects. A real-time system is guaranteed to provide a response within strict time constraints - in the order of minutes or even hours, depending on the needs of an application. The fundamental difference between the proposed approach and all other previous attempts is the acknowledgement that the construction projects are highly complex and that no single technique can gather all the information required for monitoring the productivity of a site throughout its life cycle. Instead, the proposed research will develop a flexible platform within which multiple techniques can be integrated to gather raw productivity information and consolidate such information to generate productivity reports in real time. The proposed research expects to automate the monitoring process with an integrated approach: multiple sensing systems (using videos, range images, etc.) will be developed to monitor progress of work in various construction phases and elements; a software platform will be developed to consolidate progress information extracted by sensing systems; schedules will be retrieved from Building Information Modeling (BIM) to automatically compare actual progress with the schedules and report deviations; and a web-based interface will be developed to provide easy access.

由于难以收集可靠的信息来评估正在进行的建设工作的进度，许多建设项目没有得到系统的监测。生产力评估需要人工收集数据，这是通过雇用观察员从现场收集工人的工具时间和绩效信息来进行的。由于人为错误和数据可用性的限制，这种手动收集的数据的质量很低。一些研究人员试图通过自动化监控建设项目的各个方面来解决这个问题。然而，该行业仍然缺乏一个全面的解决方案，可以促进整个建设项目的进度监测。所提出的研究目标是开发一种能够处理这种多样性和复杂性的自动实时系统，从而为建筑施工项目的进度监控问题提供最佳解决方案。实时系统保证在严格的时间限制内提供响应——根据应用程序的需要，在几分钟甚至几小时的范围内。拟议的方法与以前所有其他尝试之间的根本区别在于承认建筑项目是高度复杂的，并且没有任何一种技术可以收集监测场地整个生命周期的生产力所需的所有信息。相反，拟议的研究将开发一个灵活的平台，在这个平台上，多种技术可以集成在一起，收集原始的生产力信息，并整合这些信息，以实时生成生产力报告。拟议的研究预计将采用综合方法实现监测过程的自动化：将开发多种传感系统（使用视频、距离图像等），以监测各个建设阶段和要素的工作进展；将开发一个软件平台，以整合由传感系统提取的进度信息；将从建筑信息模型（BIM）中检索进度，以自动将实际进度与进度进行比较，并报告偏差；并将开发一个基于网络的界面，以提供方便的访问。
