Summary
Machine-generated summaryETH Zurich is procuring monument-compatible renovation works on window and French door elements in its historic Main Building in Zurich. Most elements are constructions by architect Gustav Gull from 1914 to 1925. The overall window renovation covers 437 windows in total, divided into three lots. The building is of major national cultural significance and is monument-protected by the Confederation, so special sensitivity in handling the fabric is required.
