Veloat is an Enterprise AI Layer for construction that converts fragmented project information into connected, verifiable knowledge. Its Construction Evidence Graph links contracts, specifications, correspondence, drawings, BIM references, and revision histories. In response to a question, Veloat provides an AI-generated answer alongside the relevant source clause, drawing location, BIM reference, and applicable revision, allowing users to verify the result directly. It is designed for EPC, plant, infrastructure, and building projects, where a missed requirement or superseded drawing can lead to cost overruns, schedule delays, disputes, rework, or safety risks. Veloat is a new product that consolidates technologies developed and validated through enterprise implementation projects for construction clients into a unified platform. In one of those implementations, review cycles were reduced by up to 70%, annual savings were estimated at US$3.5 million, and risk-detection efficiency increased by 200%.
