BANGKOK, Thailand – The Ministry of Transport reported that ground subsidence near the MRT Purple Line South construction site in Wongwian Yai is stabilizing, and unaffected road sections are expected to reopen gradually within one week. Deputy Minister of Transport Siripong Angkasakulkiat said the latest measurements showed average subsidence of 30–32 centimeters with no additional movement detected. Some areas have risen slightly after being injected with cement grout mixed with chemical agents to fill underground cavities.
USAR Thailand and Kasetsart University installed 10 additional sensors around nearby buildings. A drone with LiDAR is also used to produce precise three-dimensional maps and monitor changes across the wider area. Traffic restrictions will remain while the contractor drills and injects grout into about 30 underground cavities. The work is expected to take one week, after which traffic may gradually resume on sections confirmed unaffected.
The Deputy Minister stated that Prime Minister Anutin Charnvirakul instructed the Mass Rapid Transit Authority of Thailand and the contractor to provide appropriate assistance to affected residents. Officials will conduct door-to-door outreach, cover necessary temporary relocation expenses, and consider compensation for those affected by the road closures. Siripong reaffirmed that public safety and property protection remain the ministry’s highest priorities. Monitoring will continue closely, with situation updates potentially reduced to once daily if no further subsidence occurs over the next two days. (NNT)
