BANGKOK, 20 March 2012 The Bangkok Metropolitan Administration (BMA) has found that some construction materials have disappeared, resulting in a sinkhole on Rama IV Road.
The BMA, along with the Mass Rapid Transit Authority of Thailand (MRTA) and the Metropolitan Waterworks Authority (MWA), announced that 50 cubic meters of construction materials such as sand on Rama IV and Chua Pleng Roads from Hua Lampong to Wat Chong Lom Water Station have disappeared. They speculated that the leakage from the Rama IV water drainage tunnel might have washed away some substance of the road.
As a result, a five-meter wide and 2-meter deep hole was found near Thai-Belgian Bridge on Sunday evening. There are three water drainage tunnels older than 40 years old in Bangkok; locating on Rama IV Road, Henry Dunant Road, and in Soi Senanikom.
Authorities from Department of Drainage and Sewerage have been assigned to inspect all of the tunnels, while the MWA is checking for any leak from its water pipes.
