On Saturday, Bangkok Governor Chadchart Sittipunt personally assessed the progress of repairs on the collapsed section of Samsen Road near Vajira Hospital in Dusit District, which began sinking on September 24. He confirmed that concrete pouring has been actively underway, with 110 cubic metres poured overnight and an additional 120 cubic metres today, bringing the total fill to 1,105 cubic metres. Currently, concrete work is paused while electric pumps with a capacity of 25 cubic metres per second have been installed. Although light rain last night did not disrupt operations, heavy rain is expected on September 28.
Chadchart outlined plans to reinforce the area beneath the metro station with sprayed concrete to stabilize the soil, followed by sand and cement filling, then crushed stone to strengthen the surface before reopening the road. The goal remains to restore traffic by October 8. All utility connections—including water, drainage, and communication lines—will also be completed to prevent future issues. Reinforcement work on the Samsen Police Station’s foundations and piles will proceed concurrently to ensure the building’s stability. Vehicles parked there will stay until the structure is fully secured.
He emphasized that progress is on schedule and expressed gratitude to MRTA staff and foreign experts for their efforts, which have helped reassure the public. Chadchart also mentioned that the incident has highlighted the need for improved inspections on other subway lines, such as the Purple Line and Orange Line. He thanked the Prime Minister for visiting the site, which boosted morale among workers.
Regarding the request from Samsen Police to connect CCTV footage, Chadchart confirmed that the connection will be completed tonight, allowing the public to access traffic incident footage if needed.
On the affected residents, Chadchart stated that while specific timelines remain uncertain, the Bangkok Metropolitan Administration is dedicated to providing accommodation, food, and support through a dedicated coordination center.
The governor also inspected the remaining pit, noting that all gaps had been filled with concrete. Tomorrow, crews will remove debris—such as transformers, damaged concrete, and utility poles—using a 200-tonne crane where necessary, with preliminary cuts made for items that cannot yet be lifted.
