About this file
This file is a set of architectural construction drawings for a roof replacement project at the U.S. Embassy in Seoul, South Korea, prepared by the Department of State's Bureau of Overseas Buildings Operations (OBO).
The project encompasses roof replacement for three buildings: the Office Building Chancery (OBC), Consular (CON), and Annex (ESO) structures. The scope of work includes removal of existing roof systems to the substrate and installation of a new fabric-reinforced PMMA (polymethyl methacrylate) roof coating system with associated edge metal and flashings. The work involves multiple roof areas designated as Roof Areas A, B, and J, with specific attention to mechanical penthouse roofs, equipment curbs, primary and overflow scuppers, roof drains, risewalls, thresholds, pipe penetrations, and roof hatches. The drawings indicate demolition of unused or abandoned concrete curbs and mechanical unit support framing where applicable. The contract requires field verification of all measurements shown, as they are noted as approximate. The construction documents include site plans, existing and new roof plans for each building, and detailed technical specifications for various roof penetrations and transitions. The drawings are marked as preliminary at 60% completion with a release date of June 12, 2026, indicating this represents ongoing design development for a future construction solicitation.
