Construction
Helipads are usually constructed out of concrete and are marked with a circle and/or a letter "H", so as to be visible from the air. However, they are not always constructed out of concrete; sometimes forest fire fighters will construct a temporary helipad out of wood to receive supplies in remote areas. Rig mats may be used to build helipads. Landing pads may also be constructed in extreme conditions such as on ice.
The world's highest helipad, built by India, is located in the Siachen Glacier at a height of 21,000 feet (6400 m) above the sea level.

To find the mind’s construction in the face:
He was a gentleman on whom I built
An absolute trust.”
