The Vera C. Rubin Observatory Coating Plant has been successfully assembled on top of the mountain in Cerro Pachon, Chile. Prior to that, the Coating Plant was completely assembled and tested at VON ARDENNE's facilities in Germany, then dismantled and transported to Chile across the ocean. After reassembly, the Coating Plant has passed Final Acceptance Test, exceeding all the requirements imposed by Vera C. Rubin Observatory, and then the Secondary Mirror (M2) has been coated with protected silver. This paper is divided into two parts, the first part describes the constructions efforts, design characteristics, transport efforts and the assembly process; the second part of this document shows the reflectivity/coating requirements, first results over the M2 mirror and the future steps to coat the Primary and Tertiary Mirror (M1M3) mirror with aluminum.
