MTR network. Platforms on the MTR are 1,250 mm (49.213 in) above the rail for the Tung Chung line and Airport Express, collectively known as the Airport Railway lines. [1] The height of platforms on the Disneyland Resort line and the urban lines are 1,100 mm (43.307 in). The urban lines include the Tsuen Wan line, Kwun Tong line, Tseung Kwan O ...
Timber sills can span gaps in a foundation. A sill plate or sole plate in construction and architecture is the bottom horizontal member of a wall or building to which vertical members are attached. The word "plate" is typically omitted in America and carpenters speak simply of the "sill". Other names are rat sill, ground plate, ground sill ...
If the service core (which contains the elevator shafts) becomes too big, it can reduce the profitability of the building. Architects must therefore balance the value gained by adding height against the value lost to the expanding service core. [10] Many tall buildings use elevators in a non-standard configuration to reduce their footprint.
Another set of 5 passenger lifts transport passengers to the 41st and 42nd floors where they can switch lifts to reach the upper zones of the buildings, each double-deck passenger lift with the capacity of 52 passengers or, 26 passengers per deck. There are also 6 heavy-duty elevators for utility. The lift system information of the Petronas Towers
A drop structure, also known as a grade control, sill, or weir, is a manmade structure, typically small and built on minor streams, or as part of a dam's spillway, to pass water to a lower elevation while controlling the energy and velocity of the water as it passes over. Unlike most dams, drop structures are usually not built for water ...
The floor's thermal glass units are 64 mm (2.5 in) thick, consisting of a pane of 25 mm (1.0 in) laminated glass, 25 mm (1.0 in) airspace and a pane of 13 mm (0.5 in) laminated glass. In 2008, one elevator was upgraded to add a glass floor panel, believed to have the highest vertical rise of any elevator equipped with this feature. [35]
A load-bearing wall or bearing wall is a wall that is an active structural element of a building — that is, it bears the weight of the elements above said wall, resting upon it by conducting its weight to a foundation structure. [1] The materials most often used to construct load-bearing walls in large buildings are concrete, block, or brick.
For example, a single-width escalator traveling at about 0.5 metres per second (1 + 1 ⁄ 2 ft/s) can move about 2000 people per hour, assuming that passengers ride single file. The carrying capacity of an escalator system is typically matched to the expected peak traffic demand.
