In construction project management, it is crucial for the project’s success to keep track of on-site progress and to maintain construction schedules up-to-date. A lack of real-time schedule updates can result in delays in construction scheduling. Additionally, manual methods used for updating schedules can be time-consuming and often lead to inefficiencies in practice, especially with complex projects. This paper presents a novel approach integrating Artificial Intelligence (AI) and Building Information Modeling (BIM) that builds on the synergy between OpenAI’s Generative Pre-trained Transformer (GPT), and Autodesk Revit, a leading BIM authoring software. In this novel approach, a practical tool is developed that facilitates automatic updates to construction schedules using Natural Language Processing (NLP) within a BIM model. It allows field personnel to utilize their smartphones or tablets to verbally interact with and update the schedule of a project without direct access to its BIM model. This method streamlines the schedule updating process and enhances accessibility and convenience for on-site management. The AI and BIM integration demonstrated in this study represents an essential shift in construction project management, potentially leading to enhanced efficiency, time management, accessibility, and cost-effectiveness in projects. This paper provides an overview of this practical tool that works toward the integration of construction project scheduling and management into the digital age.
