Issue and/or innovation

Office building with a modern architecture with mega columns, unusual sections and innovative connections.

Reason for composite solution

The composite solution was chosen considering not only the optimized best technical solution (building height, gravitational/lateral forces applied, lateral resistance system adopted), but also the total cost, erection time-consuming and time to get the raw material from providers as well.

Technical details

Details are presented in the supplementary documents.

Specific solution/technical details

Details are presented in the supplementary documents.

Impact or effectiveness

As it can be seeing in the next items, where details are presented, the building structure is considered outstanding, due to vanguard engineering/fabrication solutions.
