abstract builds practical software products that make BIM data and project information usable, reliable, and auditable. Our tools focus on the parts of technical workflows that usually break: data quality, requirements clarity, and the ability to review change and its impact. Our products: AbstractBIM Converts IFC files into clean, consistent data for simulations, quantity takeoff, and automated analysis — reducing manual cleanup and rework. PragmaticBIM A lightweight BIM Requirement Manager to define modeling rules, attributes, and guidelines in a structured, accessible way — making requirements explicit and manageable. iterthink (beta) A data-driven review layer for documents and project artifacts. See every change, understand its impact, and build a growing audit trail — applying the same rigor to documents that BIM demands from models. Across all products, abstract focuses on data cleanup, structure, and traceability — so information can support automation, analysis, and informed decisions instead of manual fixes.
