Usually involved in the front end design, with a "typical" condition being that of a leadership role through either Schematic Design or Design Development, and then a monitoring role through the CD and CA phases.
The Design Engineer is usually involved in the front end design, typically taking the leadership role in the Schematic Design and Design Development, and then a monitoring role through the CD and CA phases.

The main contractor is the supervisory contractor of all construction work on a project, management of sub-contractors and vendors, etc. May be referred to as "Construction Manager," however, for consistency CTBUH uses the term "Main Contractor" exclusively.
Redeveloped from an original 17-story building built on the site in the 1980’s, York Place is a typical reinforced concrete structure. However, an exceptionally small site area of 27 meters by 27 meters (88x88ft), restrained the building breadth to 13 meters (43ft) which resulted in an extremely slender structure. With a slenderness ratio of 1:12, the tower would be left highly vulnerable to wind loads.
To resolve these design constraints, multiple tuned liquid dampers were devised to improve the damping performance of the building, to enhance its serviceability performance in wind event. To minimize undesirable structural impacts on surrounding buildings and nuisance to normal traffic operations below, the existing substructures of the original building were fully utilized in the design of the foundation work. The combination of a well-detailed structural layout plus the application of tuned liquid dampers cleverly fuses conventional construction technology, state of the art of engineering science and user requirements to successfully shape a stiff and robust structure which behaves adequately with static and dynamic performance in extreme wind events.
