A Corrosion Condition Assessment anddurability analysis of a concrete structure identifies the conditions which affect the long-term behavior of the concrete’s performance over time within its given environment. The aim of a durability analysis it to create a lifetime model of when the building will reach critical deterioration limit states and when the structure will repairs. The analysis can also allow owners to plan for obsolesce of a structure if necessary and plan for the end of the buildings service life. With historic concrete structures the intended design life and desired service life are often many years apart. The structures and buildings in many instances are beyond their intended service life.The approach taken when dealing with historic concrete icons is often limited by historic preservation philosophy conservation ethics limited material removal etc. Limited treatments are also available due to these constraints.A significant part of this evaluation process is a detailed Corrosion Condition Evaluation. The assessment procedure identifies deterioration factors including physical chemical structural and mechanical damages while also collecting pertinent site data such as corrosion rate corrosion potential etc. to incorporate into a risk matrix.This survey approach has been used by the authors on numerous historic concrete structures: where the loss of original material can play a significant role in the authenticity of the structure; where the concrete itself is a recognizable and defining feature of the structure; or where the concrete structure is a prototype for larger iconic buildings.This approach allows the owner to make informed decisions for the long term behavior of the buildings. It also allows for projected time frames to deterioration and subsequent modeling of behaviors. This approach assists in making the best choice of repair with the longest service life for the client’s budget.Case studies will include but may not be limited to Corrosion Evaluations of:The Guggenheim Museum by Frank Lloyd WrightThe National Gallery of Art East Wind by IM PeiPhillip Johnson’s Folly the Pavilion on the PondThe New York Dock Building
