Architecture and Building Construction work in different aspects. Architecture is about having that image of creating a building, the art aspects, building construction focuses more on how to physically create such a thing. It is important to know these things, architects and engineers must work together to figure out the scale and proportions that is appropriate to create comfortable space for human activities. Each have a critical role to play, one cannot work without the other. Francis Ching also teaches about the different systems that run in a building. Structural systems are beams, columns, etc. Enclosure systems is the “shell” (roof) of a building. Mechanical systems is the “essential services to a building”, water systems and sewage disposal is a part of mechanical systems.
