Vendor needs to provide AI scheduling tool. Artificial Intelligence (AI) construction scheduling tool requires an existing commercial–off–the–shelf (COTS) or software–as–a–service (SaaS) product capable of forecasting construction schedule risk and augmenting project teams in the development of risk–mitigation scenarios. Solution must be a predictive AI model that is pre–trained on a large and diverse dataset of historical construction projects. Able to ingest standard construction scheduling files (e.g. Primavera P6, Microsoft Project) and quantify potential schedule delays or opportunities. Furthermore, the tool must feature a conversational user interface (e.g., a Large Language Model chatbot) that allows users to ask questions about schedule risk, understand drivers of that risk, and interactively model the impact of potential mitigation strategies. Software must use a predictive AI model to forecast construction schedule risk by quantifying potential delays or opportunities. Software must include conversational user interaction (LLM–enabled) to explain drivers of risk, answer user questions about the construction schedule, and support iterative mitigation planning. Software must support ingestion of common construction scheduling and project formats.
