A helipad is a place where helicopters can land and take off. Using a helipad in a restaurant tower is like an emergency staircase that increases the level of safety, but Pasargad Company has designed other applications by imitating famous examples as well as using its creative engineers.By adding special uses, the company has multiplied the revenue from each of the restaurant tower components. For instance, sports and ceremonial use of helipad space in addition to its common use can help generate more revenue.
Of course having a helipad in a tower depends on fire department permits, which vary from city to city.

What is heliport?
A heliport is an area of land or structure that is used or intended for the landing and take-off of helicopters. In other words, it is a small airport suitable for use by helicopters and some other vertical lift platforms.
Types of heliports such as: surface helicopters, rooftop helicopters, and helipads.
A heliport can have one or more landings, each of which is called a helipad.
Examples of tall tower helipads
This structure can be made of different materials such as steel, concrete and aluminum or a combination of two or mere materials.
Today, it is mostly made in the form of space structures or in the form of a combination of concrete and steel structures, and this method is more common. The minimum thickness of concrete slab for these structures is 6 Cm.

Helicopter pad design
Helipad is a place used for landing and take off helicopters on tall buildings and towers.
If the height of a building in a city is more than 45 meters the design and construction of a helipad will be mandatory but other buildings can also volunteer to install a helipad.
Helicopters landing on helipads of tall towers
The criteria required for such buildings mainly consist of two parts Implementing rules and regulations:
The first part is the instruction NO 4314 of the National Aviation Organization and the second part is the urban planning criteria (dimensions and size of the helicopter placement plan) and loading and calculation criteria some of which we will mention.
The minimum weight of the helicopter ( for the city of Tehran) is considered equal to 40 kN.
The location of the helicopter should be a circle with a diameter of at least 18 meters, in addition a strip at least 1.5 meters wide should be considered as a safety guard around it.
Note: if there is a truss around the helipad we should be 2 meters away from the edge of the helipad with a slope of 1:2.

In addition to article 6 of the national building code, several loading rues must be observed:
For helicopters weighing more than 14 kN, a uniformly wide live bas of 3 kN/m2 should be applied alone and the structural calculations checked.
In concrete structures (final limit design method) the load coefficient of the helicopter in the first composition should be equal to 1.66.
In steel structures (designed by the limit resistance method) The load coefficient of the helicopter in the second composition should be equal to 1.66.
