when speaking of building construction one of the most important subjects that needs to be covered is systems. Every building has a system, which is an assembly or interrelated or independent part forming a more complex and unified whole. Buildings have multiple systems that keep it running and make sure that an architects main goals are meant, like safety. Some systems include the mechanical system, which provides essential services to a building, like the water supply system which provides sanitation. others include things like columns and support which would be the structural system. All these systems are necessary to ensure that the buildings requirements are fulfilled and that our safety is never on the line.
