Condition assessment projects are performed on new structures for quality assurance purposes and older structures for repair, rehabilitation and/or renovation purposes. Owners may want to change the use of an older building such that its load rating needs to be upgraded, add on to a building and/or assess its internal condition to identify areas in need of repair. Design plans and construction records are often not available for older structures. Such basic information as the material strengths, structural element dimensions, and internal concrete/masonry reinforcing details may not be known or apparent. Corrosion of metal elements, decay of wood, and cracking of concrete and masonry due to environmental factors such as freezing, freeze-thaw, moistue and chemical intrusion, and other aging effects all reduce the strength, safety and durability of construction materials over time.
