Makkah Royal Clock Tower Completes
- The Makkah Royal Clock Tower, part of the Abraj Al Bait complex 300 m from the Great Mosque, rises to 601 m and is the world's tallest clock tower with the largest clock faces[3][4]
- Construction ran from 2002 to 2011 and it opened in 2012, built by Saudi Binladin Group with SL Rasch and Dar Al-Handasah as architects and engineers[3]
- Cost is given as US$15 billion by Wikipedia and about $16 billion by The B1M[3][4]
- The tower has the highest occupied man-made space (a prayer room at 600 m, above Burj Khalifa's 585 m), and the clock is 35 times the size of Big Ben[4]
- The hotel was originally planned at 450 m and extended to 600 m mid-construction, so engineers used a lightweight steel and concrete framework limiting weight to 82,000 tonnes[4]
- Firms from over ten countries worked on it, and some non-Muslim glazing experts converted to Islam to work on site in Mecca[4]
- The facade uses 98 million mosaic glass tiles, a third with 24-carat gold leaf, and the clock face is lit by over 2 million LEDs[4]
