L&T Secures Significant Order for LIGO India Observatory Project

Larsen & Toubro Ltd has received a significant order from the Department of Atomic Energy of the Government of India for the establishment of the LIGO India Observatory. The observatory will be located in Aundha, Hingoli district, Maharashtra. The order was announced on February 24, 2026.

The project will be executed by two business verticals of L&T: the Heavy Civil Infrastructure and Heavy Engineering divisions. The scope of the project includes comprehensive engineering, procurement, and construction of vibration-sensitive, high-precision civil infrastructure. Additionally, L&T will manufacture and install an ultra-high vacuum compatible 8 KM beam tube and critical equipment for vacuum infrastructure.

The project also involves the integration of mechanical, electrical, HVAC, fire protection, vacuum control, and monitoring systems, along with all support utilities. The completion deadline for the project is set at 48 months from the start date.

The LIGO (Laser Interferometer Gravitational Wave Observatory) is designed for the detection of gravitational waves caused by cosmic events. This initiative is part of India’s flagship ‘Mega Science’ projects, developed in collaboration with premier Indian research institutions such as RRCAT and IPR, and the LIGO Laboratory of the United States, with support from Caltech and MIT.

Larsen & Toubro is a USD 30 billion Indian multinational company engaged in EPC Projects, Hi-Tech Manufacturing, and Services.
