The project involved the supply, delivery, installation, and testing of illuminated aircraft stand identification signs, online UPS systems with batteries, switchgears, and associated electrical accessories at Gautam Buddha International Airport. The work was carried out to support airport operational reliability, electrical continuity, and airside infrastructure improvement. The project included installation, system integration, testing, and commissioning activities in accordance with airport operational and technical requirements.

Objectives

The project was designed to achieve the following goals:

• Improve visibility and identification of aircraft stands through illuminated signage systems
• Enhance electrical reliability and uninterrupted power supply for critical airport operations
• Upgrade switchgear and associated electrical distribution infrastructure
• Support safe and efficient airport operational activities through improved electrical systems
• Ensure installation and testing of systems in compliance with required technical standards

Key Deliverables

The following systems, instruments, and tools were supplied, installed, and commissioned as part of the project:

• Supply, delivery, installation, and testing of 300 kVA and 150-160 kVA Online UPS systems.
• Supply and installation of accessories for 60 kVA UPS, including relocation and testing.
• High mast LED floodlights for domestic and international apron areas.
• Illuminated Aircraft Stand Identification Signs (ASIS) at international apron areas.
• Copper power cables of various sizes and related electrical accessories.
• Comprehensive installation, testing, and commissioning of all equipment per technical standards.
• Expert services for system commissioning and training for airport personnel.

Challenges

The project involved the following procurement and process-related challenges:

• Coordination of installation activities within an active international airport environment
• Maintaining operational safety and minimizing disruption to airport services during installation
• Transportation of heavy battery racks, SMF VRLA batteries and UPS from the ground floor to the basement that was 3 floors below the ground in the International terminal Building
• Laying of the 240 Sq. mm Power cables in the existing fully packed cable trench without damaging the existing infrastructure and hampering the power system
• Integration of new electrical systems with existing airport infrastructure
• Compliance with airport electrical, operational, and safety standards
• Handling and installation of specialized electrical equipment within controlled operational zones

Solution

The following structured approaches and methodologies were adopted to address the identified challenges:

• Skilled technicians and labourers moved the battery racks, batteries and UPS units to the basement under controlled safety procedures.
• Power cables were laid along routes agreed with the GBIACAO electrical department, identified on site where drawings were not available.
• Before energizing the UPS, we had a brief talk with the OEM and the UPS pre-system check and pre-commissioning were done under strict guidance from the OEM.
• The project was executed through a structured supply, installation, testing, and commissioning approach. 
• Electrical systems and equipment were installed in accordance with technical specifications and airport operational requirements.
• Coordination was maintained with airport authorities to manage installation schedules, operational access, and system integration activities. 
• Testing and verification procedures were conducted to ensure reliable performance and compliance with required standards. 

Impact

The establishment of the Installation of Illuminated Aircraft Stand Identification Sign, Online UPS with Batteries, Switchgears have delivered tangible and lasting improvements to GBIACAO operational capabilities:

• The project improved the operational reliability and electrical support infrastructure of Gautam Buddha International Airport. 
• The installed UPS systems enhanced continuity of critical electrical services, while the illuminated aircraft stand identification signs improved operational visibility and airside coordination. 
• The upgraded switchgear and associated electrical systems contributed to safer and more efficient airport operations. 

Conclusion

The project demonstrated capability in delivering airport electrical infrastructure and operational support systems within an active aviation environment. Through the installation and commissioning of specialized electrical and airport support equipment, the project contributed to improved operational reliability, safety, and infrastructure performance at Gautam Buddha International Airport.
