3. A tall building is ‘topped out’ when all its structural members are in place.
4. A tall building is considered to be ‘under construction’ when site clearing has been completed and foundation / piling work has begun.
5. A tall building is considered to be ‘on hold’ when it is widely reported within the public domain that construction has halted
Material:
A steel tall building is defined as one where the main vertical and lateral structural elements and floor systems are constructed from steel.
A concrete tall building is defined as one where the main vertical and lateral structural elements and floor systems are constructed from concrete.
A composite tall building utilizes a combination of both steel and concrete in the main structural elements throughout the building.
A concrete/steel tall building indicates a steel structural system located above a concrete structural system, with the opposite true of a steel/concrete building.
