Pasadena, CA (June 06, 2019) – A Segment Support Assembly (SSA) “pre-build” meeting at the Coimbatore facility of Larsen & Toubro (L&T) was successfully completed on May 22, 2019. The meeting was aimed at assessing the readiness of the L&T team to start manufacturing their first SSAs. Participants included India TMT Coordination Centre (ITCC) and the TMT Project Office team.
The Hawaii Department of Land and Natural Resources (DLNR) has issued a notice to proceed (NTP) to the University of Hawaii for the Thirty Meter Telescope on Maunakea. The NTP is a formal communication indicating that all pre-construction conditions and mitigation measures specifically required as a condition of the Conservation District Use Permit (CDUP) have been met. With the NTP, TMT can proceed with construction.
The India TMT Optical Fabrication Facility (ITOFF), being constructed at the Indian Institute of Astrophysics campus in Hosakote, near Bengaluru, is rapidly approaching completion. The world-class optical facility was built by India-TMT as part of its contribution to the TMT partnership.
Pasadena, CA – February 6, 2019 – The Indian Institute of Astrophysics (IIA), on behalf of India TMT, recently signed a contract with Larsen & Toubro (L&T) to manufacture 100 Segment Support Assemblies (SSA) for the TMT. L&T is one of the largest leading construction engineering companies in India.
