The project for the installation of improved tents in Mina is one of the largest projects which has been carried out in the sacred sites for the ease and well-being of pilgrims. Carried out over an area of approximately 2.5 million square meters, the project provides accommodation for 2.6 million pilgrims. The tents were constructed of fiberglass coated with Teflon in order to ensure high resistance to fire. This material, in addition, does not exude poisonous gases, except at high temperatures.
A number of criteria were set down for choosing the most appropriate shape for the tents which should have an Islamic character and be manufactured and implemented on the ground in accordance with the latest technology.
The possible shapes for these tents and the methods of assembling them were studied in order to determine the maximum utilization of available land in Mina, while taking into consideration appropriate safety and security requirements, their appropriateness to the surrounding environment, and the function of the tent camps. Each sector of land in Mina was divided into several camps, each of which possesses its own exterior wall, and is connected to other camps by pathways. Each camp is equipped with bathrooms and ablution facilities. At the entrance of each camp is a separate tent for the mutawwif (pilgrim guide), in addition to an electric power distribution point, a kitchen and a rubbish bin.
Each camp is encircled by metallic walls and is provided with main entrances as well as emergency exits which can be opened easily from within the camp. Paved and illuminated passageways permit easy movement within each camp and signs provide location information.
Each standard tent measures 8 x 8 meters; in addition, there are smaller (8 x 6 meters) and larger (8 x 12) tents. They were designed in such a way as to afford protection from the elements, including wind and storms, and to be easily assembled.
Due to the ever-present danger of fire, the necessary safety precautions were taken to protect the tent camps.
A comprehensive fire safety network has been implemented in order to achieve this aim, consisting of major fire hydrants in the streets of Mina and a water supply network which covers all of Mina.
This network is supplied with water from tanks situated on top of the mountains surrounding Mina, from where pipes supply water to Mina.
The length of the pipe network is about 100 kilometers, while the diameter of the pipes themselves ranges from 250 to 700 millimeters. In order to assure that the network carries out the function for which it was deigned, it has been equipped with 800 water taps and 740 fire hydrants.
