building physics
A company which maintains the structural and mechanical systems of a building.
Companies responsible for the active maintenance of a completed building's structure and mechanical systems.
The activity is continuing work on the structure and mechanical systems of a completed building. The building is already constructed, so the service concerns maintaining its existing systems and fabric rather than executing its original construction.
Structural engineering designs the framework, and mechanical engineering designs mechanical systems. The active maintenance described here concerns those parts of the building after completion.
