Team F.G.S. brings together leaders in the retrofit robotics, architecture, and construction fields to address the issues of sensing, mapping, and minimally invasive retrofits. Our user-friendly BIM and our gCERT modeling software address the needs of owners, contractors, and architects while providing the data needed to enable robotic retrofits. Combined with the FLX BOT, our robotic retrofit tool that can perform minimally invasive, surgical envelope remediations like caulking, aerosol sealing, and foam insulating, we have created the ideal holistic solution to building envelope retrofits.
