Project Brief:

The new 102 meter tower has been built adjacent to the present ATC tower. It’s the tallest in the country and 7th tallest in the world. As a matter of interest, the structure is said to be 40% taller than the renowned monument, Qutub Minar. The new ATC tower has 21 controller positions with a 360 degree view at the visual control room and 12 ground controller positions at operational level. Other than being the tallest ATC tower in the country, this is the first time in the country that Tuned Mass Damper (TMD) technology has been used to increase the comfort of occupants and reduce building sway.

Sterling and Wilson was entrusted with complete LVS, Plumbing and Fire Fighting in the tower.

Our Scope: LVS:

  • SITC of Fire Alarm System- This is a design and built system for fire detection and firefighting which is as per FM guidelines these alarms may be activated from smoke detectors, heat detectors, water flow Switches, which are automatic or from a manual Fire Alarm Pull Station. Installed Fire Alarm System is Notifier Make solution
  • PA SYSTEM (Make-Bosch) – PA system is an electronic amplification and distribution system with a microphone, amplifier ,controller and speakers In case of fire automatic announcement occurs to evacuate the building and also we can do manual announcement zone wise to communicate with people
  • SITC of Public address system (PA system)- It is an electronic amplification and distribution system with a microphone, amplifier and speakers used to allow a person to address and evacuate the building in case of fire. Fire alarm systems utilize emergency voice alarm communication systems (EVACS) to provide pre-recorded and manual voice messages. Voice Alarm systems are typically used in high-rise buildings, arenas and other large “defend-in-place” occupancies such as Hospitals and Detention facilities where total evacuation is difficult to achieve
