GOC2271782-CS RFP Lite - GOC2271782-CS RFP Lite De-Scale Building Exterior

The masonry is experiencing signs of delamination / peeling of stone which is scaling off in layers. There are also signs of  heavy efflorescence in a few locations, crack patterns / displacement commonly at the upper corners of the building and large spans of masonry with inconsistent mortar joints (including sealant through many joints) and a lack of control joints.   Descaling of all exterior walls, to remove all loose and detached pieces of stone on the façade, is required and to repoint and address control joints as necessary.  Consultant to perform a thorough investigation of all elevations to determine the extent of descaling and repointing required as well as to ensure proper drainage / weep holes are present and investigate any signs of water damage and flashings. As part of the technical investigation (TI), the consultant will provide a risk table / matrix which will clearly identify and prioritize which elevations (or sections of each elevation) are to be addressed in order of priority as per the risk matrix. The GFC is a Recognized Federal Heritage Building and any interventions must respect the heritage character of the building. Conservation specialists and masonry experts should be consulted throughout the project.
