Bangkok: The recent collapse of a warehouse at Laem Chabang has prompted urgent calls for the inspection of steel structures across Thailand, especially with the onset of summer storms. Professor Dr. Amorn Pimanamas, President of the Structural Engineers Association of Thailand, highlighted the issue on MCOT News FM 100.5, suggesting that the incident underscores a recurring problem tied to cost-cutting measures in construction.
According to Thai News Agency, the warehouse, still under construction, suffered a structural failure when its pillars fell, dragging down the upper sections. The incomplete nature of the building, with anchors and connections not fully installed, left it vulnerable to the strong winds typical of the March to May storm season. Dr. Amorn noted that similar incidents have occurred in the past, including one in Bang Na earlier this year, affecting steel structures like advertising signs and gymnasiums.
Dr. Amorn advocates for stricter construction standards, particularly concerning temporary bracing during construction, despite the potential increase in costs. He emphasized that the safety of life and property outweighs financial considerations. Although the Structural Engineers Association offers annual safety advice, it lacks the authority to enforce compliance, relying instead on disseminating knowledge to engineers. He called for more stringent regulations to prevent future collapses, noting that not only under-construction buildings but also older structures with rust or loose connections are at risk.
The professor also raised concerns about contractors potentially reducing costs by using substandard materials, which compromises wind load resistance. He recommended thorough site surveys and design plan reviews to address any necessary reinforcements. Additionally, Dr. Amorn advised the public to consult the association before extending homes or constructing garage roofs to ensure safety.
Furthermore, Dr. Amorn issued a warning regarding damaged advertising signs, urging their immediate removal to prevent potential collapses during storms. Owners of such structures could face criminal charges if they fail to act. He also suggested that agencies inspect large utility poles annually before storm seasons to check for rust or loose bolts, while recommending regular road scanning to detect subsurface cavities and prevent incidents like the recent road subsidence on Charansanitwong Road.
