King Abdul Aziz Endowment Project and Makkah Clock Tower

Located in the holy city of Makkah and overlooking the holy mosque the King Abdul Aziz Endowment Project and Makkah Clock Tower is over 600 meters tall, houses the worlds largest clock and a whole host of specialized systems

The task was:

  • Operate and maintain the worlds largest clock

  • Design and implement an IT system to offer an integrated control for the specialized systems

  • Offer integrated facility management for the tower top

Unique solution:

ATOM is extremely proud to have contributed to the successful implementation of this project. In the implementation phase ATOM was contracted to install the following highly specialized systems:

After the completion of all specialized systems ATOM was selected by the buildings facility manager Facilitect as a subcontractor to operate and maintain the following special systems:

  • Media Walls
  • External Lighting (Façade Illumination)
  • Clock & Pediments LED Systems
  • Clock Mechanisms & Clock Hands
  • Retractable Lightning Protections
  • Photovoltaic System
  • Beacon Lights
  • Flash Lights
  • Laser Lights
  • Crescent Hatch
  • Fiber Optic Network
  • IT Department
  • BOCC

ATOM’s team of engineers and technicians are now responsible for the smooth operation of this marvel of engineering and technology which includes multiple one of a kind systems and world firsts.

Specialized system facts:
Media Walls

  • Contain 1,208,904 of LEDs
  • Have 2,200 square meters of screen surface
  • Have 76,398 LDMWs in a single network
  • Have more than 12,000m of fibre optic cable
  • East and west media wall have 6 doors per side

External Lighting (Façade Illumination)

  • Contains of 1702 Luminaires
  • 81,200 KW Connection Power
  • 187 meters altitude difference (Astronomy 1 to Crescent)
  • Work takes place under high risk conditions

Clock & Pediment LED Systems

  • Contain 700.000 LED points
  • Have 7,000 square meters of facade illumination
  • Have 4,122 LDMs in one network

Clock Mechanism & Clock Hands

  • The biggest clock on the world
  • The biggest clock hands in the world in which a technician can walk upright

Retractable Lightning Protectors

  • Selection of Class I protection because of the extreme height and the special location any stroke of lightning with an amplitude up to 200 kA can be catch caught and earthed
  • The complete lightning protection consists of 800 fixed lightning rods and 20 retractable Franklin rods

Photovoltaic System

  • The upper area of the Jewel is fitted with 288 solar panels, generating the four clock units’ power
  • The system consists of more than 11,000 photovoltaic cells
  • The generated energy provides power for the four clock drives for a sustained continuous operation and feeds a large battery used as UPS

Beacon Lights

  • The power of the rotating beacons which are installed on the Mecca Clock Tower are comparable to the 10 rotating beacons of the French Eiffel Tower
  • The beacon lights are the only one 10 KW beacons worldwide
  • 10 KW beacons have never been installed a such height or on a Tower
  • 60 beacons installed across four different levels
  • Each of them is a custom-made product with 7 KW and 10 KW XENON illuminates

Flash lights

  • 21,000 green and white sparkling software controlled lights installed on the tower give the possibility to run various illumination scenarios for different occasions
  • Each of the fixtures contains a 30-joule XENON flash bulb and 10 flashing green LEDs

Laser lights ASER LIGHTS

  • The most powerful lasers in the world
  • Total of 4 beams, each beam is 3.7cm wide, the widest beam in the world
  • Each beam has a performance of 400 Watts
  • The laser beam reaches beyond the atmosphere

Crescent Hatch

  • The crescent hatch at the Hilal (on the Top) is designed to protect the interior and the equipment in case of bad weather conditions
  • The hatch can be open for any kind of services (crescent service crane and switching of external lighting at night)

Fiber Optic Network

  • Over 20 kilometers of fiber optic cable to be maintained
  • single and multimode fiber optic cables installed
  • different termination plugs

IT Department

Responsible for:

  • Installation
  • Software development
  • Improvement and operation and maintenance of “Building Operation and Command Center” (BOCC)
  • Providing 24/7 support for all subsystems
  • Establishing and introducing of O&M of multimedia installation on the exhibition
  • 20 IT rooms with IT equipment spread across the entire building
  • Installed network is cross-linked from the building entrance on the ground floor to the Hilal at a height of 600 meters
  • Core-network with over 50 IBM and Cisco enterprise class switches interconnecting all subsystems
  • Entire network consists of over 1000 nodes (switches, firewalls, servers…)
  • IT department works with Telecom class copper and fiber optic installation
  • Using testing equipment → FLUKE and FUJIKURA
  • IT Department is developing the design for future projects:
    • wireless HD CCTV system for external monitoring of clock faces and media walls
    • central environmental monitoring system of all IT rooms
    • modern virtualized working environment for all ATOM employees
    • internet connection for the Makkah Time Institute NTP Servers
