The restoration of a stone façade, whether it is a marble monument or a limestone-clad office building, is not a straightforward scope that easily fits into the typical design and construction process. Simply put, it is not a discipline or process that is "set in stone." Not only are restoration techniques constantly evolving, which is challenging to describe in architectural specifications, but the assessment and documentation of potential repairs is not fully possible until temporary access like scaffolding is erected, which presents a challenge during construction from both a budget and schedule perspective. This presentation will provide an overview of basic cleaning and restoration techniques; how these techniques have evolved over the past decade due to new technologies and scientific research; and potential solutions to better integrate façade restoration scopes into the design and construction process.
