L&T Electrical & Automation FZE (LTEAFZE) has won a major order worth $7.6bn (QAR27.7bn) from Qatar Rail Company for Phase 1 of Doha Metro.
The scope of the order encompasses supply, installation, testing, integration, commissioning, and five years’ maintenance of network-wide building automation and control systems (BACS) for 37 stations.
LTEAFZE, was nominated by Qatar Rail for network-wide implementation of BACS after a meticulous assessment of its capabilities.
The framework agreement comprises nine contracts with design-and-build (D&B) contractors, which relate to the stations and tunnels of multiple lines, and a five-year maintenance contract with Qatar Rail. The deals will involve work on Doha Metro's Red Line, Green Line, and Gold Line.
S C Bhargava, senior vice president and head of L&T's E&A Business, said: “LTEAFZE’s core strengths for project management, domain knowledge, and application engineering will enable us to offer distinctly superior and proven system integration solutions by leveraging L&T’s capabilities built over four decades.”
Doha Metro will be built in two phases: the first will see the construction of three out of its four lines (Red, Gold, and Green), and 37 stations spanning 111km of tunnels and 8.7km of viaducts.
Phase 1 will be completed according to a fast-paced schedule, with the handover of all 37 stations by August 2018. The revenue period for this phase is due to commence by the end of 2019, with lines due to open to the public by 2020.
Those behind Doha Metro have targeted the provision of transportation for more than 600,000 commuters per day by 2021.
Phase 2 of the project is due to be completed by 2026. It will involve the expansion of Phase 1 lines, and the construction of an additional Blue Line and 72 additional stations.
The purpose of BACS is to control and supervise mechanical, electrical, and plumbing (MEP) systems. The project requires a structured and systematic approach to ensure all requirements are met with regard to reliability, availability, maintainability, and safety (RAMS).
Interfaced with BACS are the MEP systems and sub systems like station air conditioning systems, special ventilation system for life safety, fire-fighting system, LV power systems, addressable lighting systems, vertical, and horizontal transportation system and plumbing system at stations and tunnels.
