The civil engineers who help preserve historic buildings and other landmark structures live a sort of double life. For while they can work in ways that are similar to traditional structural engineering or other engineering disciplines, they must also deal with areas or aspects that can be unfamiliar to their fellow engineers. These efforts, known as either preservation or conservation engineering, require an understanding of archaic structural systems that are no longer widely used as well as archaic materials, such as cast and wrought iron, and how they differ from each other and from modern steel. It is important to know the properties and capacities of different mortars, masonry materials, and wood products. Engineers on preservation projects may need to work more closely with architects and contractors tJian they might otherwise as well as with specialty craftspeople and various government agencies or preservation-focused entities to obtain approvals, funding, or even information. |
