| Overview | |
|
The 16-storey office building was built with a central concrete core and a steel frame which supports profiled steel decking of the floor slabs. The main issues considered were: long life (long-span steel frame), flexibility, a steel structure can achieve large spans that maximize the flexibility for office space planning, and energy conservation. Flexibility was achieved with the omission of intermediate columns and with the use of the raised floor system and demountable partitions. The building is more adaptable to new users and therefore the life of the building is extended. Also steel is recyclable. This project used design and built concept, and had the advantage that all members of the team (design, production and construction) are as a whole, which eliminated many contractual issues. |

|
| Central Concrete Core and Steel Frame | |
| The 14m clear span was achieved with less structural depth than with concrete, using high strength steel beams, the webs of which also accommodated bigger voids for the passage of services. | |
 |
|
|
|
|
| Raised Floor System | |
 |
|
|
The building floor-to-floor height is 3,950 mm and the ceiling height is 2,500 mm, over a 200 mm raised floor. |

|
| Stone-concrete Precast Panels |
|
|
|
|
|
The panels were fabricated in Yuen Long and transported to the site and positioned. The stone from Italy, was assembled face down into the precast steel mold. A joint seal was put between the stones. A plastic sheet and stainless steel pins were disposed and concrete was poured. There are over a thousand panels with a maximum weight for the largest one of 12 tonnes. They were hoisted up and clipped onto adjustable steel brackets, secured from within. The erection was possible without scaffolding and no stone workers were required on-site. |

| The stone-clad precast facades |
| Advantages : |
| - Ease of installation |
| - Safety |
| - Uniformity |
| - Durability |
| - The system reduces
the need for steel in the outside environment |
| Disadvantages : |
| -
Heavier
system increasing loads to the columns and the foundations. |
| -
Should be
considered at an early stage of design, as the building frame should be pre-designed to accommodate this additional façade loading |
