Holy Site Expansion
„The Great Mosque of Mecca“, also known as the Haram Mosque, is a site of pilgrimage for the Hajj, and surrounds the Kaaba in the city of Mecca. Every Muslim must do the Hajj at least once in their lives if able, which includes circling the Kaaba seven times within the mosque. The Haram Mosque has undergone major renovations and expansions through the years under the control of various caliphs, sultans and kings.
In 2008, the King of Saudi Arabia, who is titled the Custodian of the Two Holy Mosques, started the planning of the expansion of “The Great Mosque of Mecca“. To serve the increasing amount of pilgrims, the mosque's capacity needs to be raised from 770,000 to over 2.5 million worshippers. In August 2011, the Government under King Salman started with the expansion, which covers an area of 400,000 m2 (4,300,000 sq ft). Now the Haram Mosque is the second largest building in the world and the largest mosque. Equipped with a huge sliding dome and sliding hatches, a four level walkway (Mataf) and two new minarets, bringing the total number of minarets to eleven, it´s an impressive piece of architecture and technology. All closed spaces are air conditioned.
To accommodate the worshippers, a new complex in the north of the Mosque has been built, including a multi-level stairways and tunnels, a gate named after King Abdullah, and a huge hotel arrangement crowned by a 601m high clock tower, the “Abraj Al-Bait“, (Arabic: Towers of the House). PCT built the Clock faces and clock hands, the composite ceiling above the clock and the crescent with prayer rooms. At 43 m × 43 m (141 ft × 141 ft), the four clock faces are the largest in the world, visible from 25 kilometres (16 miles) away.
PCT has built major parts for the expansion of the Haram Mosque:
To provide space for worshippers to perform the prayers near the Kaaba a temporary mataf has been built in 2014 and completely dismantled and removed after May 2016. This unique carbon composite structure maintains the capacity during the 3-year renovation phase and is the largest carbon fibre reinforced civil structure in the world.
The Mataf Ceiling encompass all four levels of the Mataf walkway. When complete, this decorative composite ceiling will cover an area of appr. 192,000 square metres. The integrated lightning is designed and installed by PCT Green Energy.
The ceremonial dome is a movable dome in both a closed and open position. Scope of work includes the upper roof and lower roof, outer shells, marble friezes, tambour, drainage pipes, gratings, LED light poles, fall arrest, upper roof/lower roof inner shells, coffers/soffits panels and the mechanical motor to move the dome.
