What does “erection” refer to in building terminology?

In building terminology, the term "erection" specifically refers to the process involved in construction, particularly the assembly of structures or components on site. This can include putting together the framework of a building, erecting walls, beams, and other structural elements that form the skeleton of the structure. Erection is a fundamental step in construction, emphasizing the physical act of bringing together materials to create a finished building.

Contrasting with the other definitions, design focuses on planning and architectural schematics, which precede the physical work. Demolition pertains to the removal of existing structures, which happens before or when a new building is being erected but is not part of the erection process itself. Installation generally refers to placing specific components or systems into a structure (such as plumbing, electrical systems, or fixtures) after the primary construction has taken place. Therefore, within this context, "erection" is most accurately associated with the construction phase of building.
