The Mass Rapid Transit Authority of Thailand (MRTA) has taken responsibility for the massive sinkhole that left a hole dozens of metres deep in front of Vajira Hospital in Bangkok.
The spot falls under Contract 1, which involves the design and construction of the tunnel and underground stations along the Taopoon-National Library section, covering a distance of 4.8km and worth 19.43 billion baht (RM2.54bil).
