Assessment, Maintenance, and Repair of Transitional Masonry Structures #6: Implementation of a Rehabilitation Project for Transitional Masonry

Once an assessment is complete and a rehabilitation approach has been selected, implementing the rehabilitation work is the next milestone. Bid documents for rehabilitation projects of traditional masonry wall systems should address two fundamental issues. First, all existing conditions, particularly concealed conditions, are not known and can’t be known until the work begins. Further, these conditions are progressively revealed as the work progresses. Second, the as-built geometry of the concealed portions of assembly may differ from what was revealed during the investigation or what was shown on the drawings. These geometries and concealed conditions could require modifications of the assumed repair details and potentially the scope and extent of repairs. Once the repair work begins, interaction and communication between the contractor, designer and owner are critical to the success of the project and controlling project costs. This session introduces the basic approaches for implementation of the rehabilitation including document preparation and field implementation of the repairs.

During Existing Masonry Night School: Assessment, Maintenance, and Repair of Transitional Masonry Structures, instructors discuss the most common issues in assessing, maintaining, and where needed, repairing masonry cladding systems constructed in North America between the 1880 and 1945.
