According to BEUMER, the new BHS began operation successfully and on-time due to extensive testing prior to the opening of the Terminal.
Testing, it says, included the processing of over a million bags in addition to the training of all ground personnel.
In addition, Changi Airport Group (CAG), conducted more than 100 trials involving 2,500 airport staff and 1,500 volunteers during the Operation Readiness and Airport Transfer (ORAT) period in preparation for the opening of Terminal 4.
Terminal 4's baggage handling system integrates conventional check-ins, self-check-ins, a CrisBelt conveyor with integrated hold baggage screening, a CrisBag tote-based Independent Carrier System (ICS), overall controls and CCTV. 
The CrisBag system, with integrated Early Baggage Store (EBS), spans 5,000 linear metres and is designed to provide the highest level of availability and the shortest transport times combined with 100% track and trace capability.
Controlled by BEUMER Group’s software suite, the system enables Terminal 4 to process 5400 bags per hour.
"Changi Airport has been using BEUMER Group technology since 2002, when the tilt-tray sorter was installed in Terminal 2,” notes managing director, Klaus Schäfer.
“The original contract was followed by the installation of a CrisBag system inTerminal 3 which operates as a dual baggage sorting system and an inter-terminal transfer baggage system between Terminals 1, 2 and 3."
T4's opening has increased Changi’s total capacity to 82 million passengers annually.
