The completion of advanced maintenance and comprehensive rehabilitation works on Dubai Metro’s tunnel infrastructure has been announced by the Roads and Transport Authority (RTA).
The maintenance works are said to align with the RTA’s vision for sustainable operational excellence, delivered through an integrated preventive and corrective maintenance framework built on advanced technologies and innovative engineering solutions. The framework enhances the efficiency of Dubai Metro’s tunnel infrastructure, extends its operational life, and maintains the highest levels of readiness and safety.
According to a statement, the works form part of the RTA’s ongoing efforts to enhance operational safety, ensure service continuity with high efficiency and reliability, and preserve vital assets in line with the highest international standards and recognised best practices in the rail sector.
The advanced tunnel maintenance and management programmes cover periodic inspections, specialised cleaning, resolution of technical observations, rectification of operational defects, replacement and upgrade works for assets that have reached the end of their service life, and continuous improvement projects aimed at sustaining optimal system performance over the long term.
Over the past year, the RTA said it carried out 51 specialised tunnel inspections under precise operational plans. These inspections led to the identification and resolution of 873 corrective maintenance tasks to high efficiency standards.
Key performance indicators recorded outstanding results, with the RTA achieving 100% of its preventive maintenance targets and 100% of its corrective maintenance targets. This reflects the RTA’s corporate commitment to safety, asset sustainability and operational service quality, the RTA outlined.
As part of its efforts to maintain a safe and sustainable operating environment, enhance asset efficiency and extend asset operational life, the RTA said it continues to carry out periodic and comprehensive tunnel cleaning works. These works involve advanced cleaning methods that combine manual cleaning with high-pressure washing technologies, ensuring the effective removal of dust, debris and surface build-up that may affect operational safety or system efficiency.
All maintenance, rehabilitation and inspection works are carried out in accordance with recognised international standards and global best practices in the rail sector. These works also focus on developing technical capabilities and strengthening continuous training and qualification programmes for specialised teams, ensuring alignment with the latest technologies and international standards while supporting the readiness and capability of teams to uphold the leadership of Dubai’s mass transit system, the RTA concluded.
