Initial Inquiry

  • For 2014, JCDecaux cherry picked iconic sites at Singapore Changi Airport for the integration of state-of-the-art digital media landmarks.

  • The new installations should be big, bold and beautiful but also innovative, captivating and inspiring; complementing JCDecaux’s existing suite of static and classic digital solutions.

Identified Needs

  • The Solution had to provide a high level of versatility for fresh, experiential advertising.  
  • The Arrival Halls were identified as locations that would guarantee maximum coverage and frequency, as well as close proximity to passenger flows.  
  • The Solution had to complement and integrate the interior design of the identified space, yet offer maximum campaign visibility within the spatial restrictions. 
  • Content production and scheduling had to be easy, to allow for clients to pioneer the  innovative medium.

Delivered Solution


  • Strategically positioned between the escalators and staircase at both arrival immigration halls within Terminal 1, the Digital Towers are showcased as digital media landmarks for all exiting passengers. 
  • The Digital Towers are a customized & derived version of the TwistTowers from GTG
  • Standing at 7 meters in height, the Digital Towers were designed to be visible to passengers on both floors of each atrium. 
  • For versatility across multiple advertisers, modular stainless steel cladding was chosen for a timeless look and to allow additional customised wrappings to enhance selected campaigns.


  • A triangular totem with 3 rotatable layers, the derived TwistTowers also offer advertising visibility from multiple perspectives, each side offering approximately 5m2  of advertising space across 3 x Full-HD.
  • Powerful precision rotation function coupled with whispering decibel ratings ensure that the high quality content remains the centre of attention. 
  • The programmable screen rotation can be co-ordinated with customised image reproduction such that content can be run in synchronicity or individually.


  • Each Digital Tower consists of 9 individual displays that allow for high quality and creative, eye-catching content. 
  • Presented content on the displays may be designed to interact with the rotation layers and be adapted in real-time to situational needs. 
  • An elaborate Plug-In for Adobe After Effects delivers support to agencies for easy production of impressive content.
  • Both Digital Towers can be operated and scheduled centrally and remotely via an intuitive CMS, developed by GTG.
