Located along to 2 main streets the Exhibition Street and La Trobe Street our site is an important site in the CBD. We wanted to design something that would stick or stand out of the crowd in this area of the city. We infact wanted to experiment with out shape and core placement. We cut the corner of a square building making our floor plates polygonal in shape. we used a triangular core along the cut side of the square base. We design an exoskeleton along this cut surface keeping in mind the wind load the tower may experience. Site: The site is 8844 sq.m (92.5m x 95.5m). Total area of the building being 122047 sq. (Gross Floor Area) with total Net Lettable Area being 100047 sq.m. This makes the building 81.9% efficient. With our overall height being 350 meters above sea level. Set back of 5m and 10 m from the boundary of the site was taken into consideration. Floors: Our building has 3 podium floors which are double volume, which makes it a 12 m high podium from ground. The tower also has 62 floors which also include the office and sky floor. The office areas are 4m in height and the mechanical floors are double volume and placed every 20 floors. Out sky garden is 12m in height. We notice that as the height of the building increases the efficiency of the building keeps on increasing. Our core size also decreased as we went up giving further additional area for use. Lifts and core: There are 16 lift shafts. 4 for the low riser area. 4 for the mid-rise area. 6 for the high rise area and 2 for the sky rise area. This allows efficiency to increase as we go up since we require less lifts hence giving us more area to use. Our core is a triangular core in a rectangular building. We have all our staircases and bathrooms in this core. We placed the long side of the triangular code along the cut floor plate. Crown and exoskeleton: The exoskeleton of the building continues to the crown and form a triangular shape. This exoskeleton is along the cut of the floor plates and in the direction of the wind hence protecting the tower against wind load.
The structural system used is a tubular structural system - tube in tube with concrete as the primary material for the tower. Triangular core with a square floor plate is used to achieve maximum efficiency. Tower: The tower consists of a concrete core with R.C.C structural system. The standard grid for the structural column is 6.00m, however, it expands to 7.2 m and reduces to 4.8m at some junctions but maintains a building module of 1200mm. The concrete column maintains a thickness of 1200 x 1200 mm at low-rise level thereafter it reduced to 900 X 900 mm at a mid-rise level and 750 – 750mm at high-rise level as the structural load reduces on the higher levels and is greater at ground level. The similar approach is used for the concrete core thickness which is as follows: Low-rise Level – 600mm thickness, mid- rise level – 450mm thickness and High-rise level – 300 mm thickness. In relation to the column grid, the structural system consist edge beam running through the peripheral of the tower with a dimension of 450 X 900 mm and primary band beam of 1200 X 600 mm (W X D) connecting the core to the column and secondary beam of 900 x 600 mm (W X D) from beam to beam. Lateral Load: To support the tower from the resisting lateral load, a combination of megastructure with a braced system is used to support the design of the North Eastern tapering of the tower whereas Belt and Outrigger system are used to support the entire structure. Outrigger truss (Web X Flange - 620 X 230 mm) is used to tie all the columns together and Outrigger brace (Web X Flange - 310X 115 mm) are used connecting back the column to the core at mechanical levels. The North Eastern corner of the tower has a dynamic tapering which is resolved by using megastructure with a braced system with two primary slanted columns of 900 X 1800mm running and two secondary slanted columns of 1200 x 1200 mm for additional support of the megastructure as it is not perfectly vertical. Podium: The podium consists of shop, therefore it has been provided with a floor to floor height of 8.00m. It maintains the structural grid of the tower and the building module of 1200mm. On the northeastern atrium, space frame system is used to achieve a clear span with a height of 24.0 m. Crown: The Steel megastructure at the northeastern façade of the structural system extends to the top and creates a significant impact to form the crown. Steel hollow supports and cross bracing are the primary material and support system used for the crown. Slanted columns are introduced at ends of the tower at the sky rise level. SkyRise Level are provided with a massive height of 12.0 m, the idea is to taper the end of the tower and blend it along with the crown to create a significant impact.
