KLCC Park
Spanning 17 acres below the building is the KLCC park with jogging and walking paths, a fountain with incorporated light show, wading pools, and a children's playground.
Suria KLCC is one of the largest shopping malls in Malaysia.
Skybridge
The towers feature a skybridge (constructed by Kukdong Engineering & Construction of South Korea) between the two towers on 41st and 42nd floors, which is the highest 2-story bridge in the world. The bridge is 170m above the ground and 58 m long, weighing 750 tons. The same floor is also known as the podium, since visitors desiring to go to higher levels have to change elevators here. The skybridge is open to all visitors, but free passes (limited to 1700 people per day) must be obtained on a first-come, first-served basis. The Skyway is closed on Mondays. Visitors are only allowed on the 41st floor as the 42nd floor can only be used by the tenants of the building.
The skybridge also acts as a safety device, so that in the event of a fire or other emergency in one tower, tenants can evacuate by crossing the skybridge to the other tower. However, the total evacuation triggered by a bomb hoax on September 12, 2001 (the day after the September 11 attacks destroyed the Twin Towers of the World Trade Center in New York City) showed that the bridge would not be useful if both towers need to be emptied simultaneously, as the capacity of the staircases was insufficient for such an event. Plans thus call for the lifts to be used if both towers need to be evacuated, and a successful drill following the revised plan was conducted in 2005.
The Lift System
The main bank of Otis lifts is located in the centre of each tower. All main lifts are double-decker with the lower deck of the lift taking passengers to odd numbered floors and upper deck to even numbered floors. In order to access an even numbered floor from ground level, passengers are required to use an escalator to access the upper deck of the elevator.
From the ground floor, there are three groups of lifts. The "short haul" group of 6 lifts take passengers to floors between level 2/3 and level 16/17. The "mid haul" group of 6 lifts take passengers to floors between level 18/19 and level 37/38. There is also a set of shuttle lifts that take passengers directly to levels 41/42. In order to get to levels above 41/42, passengers are required to take the shuttle lifts and then change lifts to the upper floors. These connecting lifts are placed directly above the lifts serving levels 2 to 38. The pattern now repeats with the upper levels, one set serving =levels 43/44 to 57/58 and one set serving levels 59/60 to levels 73/74.
Apart from this main bank of lifts, there are a series of "connecting" lifts to take people between the groups. Unlike the main lifts, these are not the double-decker type. Two lifts are provided to take people from levels 37/38 to levels 41/42 (levels 39 and 40 are not accessible as office space). This avoids the need for someone situated at the lower half of the building to go down to the ground floor in order to gain access to the upper half of the building.
The lifts contain a number of safety features. It is possible to evacuate people from a lift stuck between floors by manually driving one of the adjacent lifts next to it and opening a panel in the wall. It is then possible for people in the stuck lift to walk between elevator cars.
During an evacuation of the buildings, only the shuttle lift is allowed to be used. This is because there are only doors at levels G/1 and levels 41/42 therefore should there be a fire in the lower half of the building, this enclosed shaft would remain unaffected.
