A construction mishap plunged Bangkok’s Cultural Centre MRT Station into chaos on Friday, 5th September, flooding parts of the facility. The Governor of Thailand's Mass Rapid Transit Authority (MRTA), Kajpajon Udomthammaphakdi, has now mandated AIA to cover the costs of the damage.

 

In a decisive meeting with the Bangkok Expressway and Metro Public Company Limited (BEM) and AIA, Kajpajon confirmed that AIA has agreed to full liability under their construction agreement. The flooding, which originated from work on an underground walkway connecting the MRT station to the new AIA office building, revealed not just a physical breach but potential gaps in compliance and oversight procedures.

 

Alarming for many was the fact that this project hadn't appeared in AIA's initial construction permit. This omission has spurred questions and scrutiny from both the authorities and the public.

 

The deluge was triggered by a design flaw in the tunnel’s ventilation. Openings designed to support airflow had been installed level with Ratchadaphisek Road’s surface. When over 100 millimetres of rain fell, these openings became vulnerable inlets for water, funnelling it directly into the MRT station through an active construction zone near its second entrance.

 

AIA's oversight starkly contrasts its original proposal aimed at mimicking a successful model at Rama 9 Station. Yet, deviations in execution resulted in this watery mishap.

 

Reacting swiftly, AIA has halted all construction indefinitely. The company is now tasked with developing robust preventative strategies to avert any repetition of such incidents before any building resumes. These measures will be scrutinised by the MRTA to ensure compliance with future engineering and safety standards.

 

BEM is conducting an extensive evaluation to determine the full extent of the flooding's impact, with a comprehensive report expected by month's end. This assessment will guide reparative actions and financial compensation.

 

This incident highlights broader issues in urban infrastructure projects in Bangkok. Compliance with construction plans and adherence to safety regulations are of growing concern, prompting many to question the mechanisms that oversee such large-scale projects.

 

While no timeline for the resumption of work has been disclosed, it's clear that the MRTA is taking a stringent stand. The agency underlined the requirement for rigorous adherence to established engineering practices as non-negotiable for future developments.

 

The Cultural Centre MRT Station disruption serves as a stark reminder of the complexities involved in urban development. Authorities and construction firms will undoubtedly face increased scrutiny as this high-profile incident unfolds. AIA’s responsibility in compensating for the damages is but one aspect of a multifaceted issue that calls for heightened diligence in urban planning and project execution.

 

Residents and commuters alike are awaiting further updates, hopeful for enhanced safety measures and quicker resolutions to maintain the reliability and integrity of Bangkok’s transit systems.

Great planning.

In a city that is sinking , and with torrential rain,

they build tunnels for a metro system.

What can go wrong here.

Who puts an air intake at road surface level. This will obviously become a storm water intake.

 

"revealed not just a physical breach but potential gaps in compliance and oversight procedures."
Who would have guessed it

A photo I hoped to never see.  I often think about this in heavy rains and while passing under rivers.....

Scary the complete lack of oversight.  AIA is surely at fault but MRTA should have been closely monitoring and approving any construction and, obviously, wasn't.

That's why they want submarines!

Obviously there was during the construction strict adherence to International standards

Genius, who would have thought?

Actually any competent architect or engineer.

Somebody that wants to get paid twice.

 

Once to build it.

 

Once to come back and built it properly. 

One thing most untold about subway train(and its stations).

 

It takes constant usage of draining pumps.

Or that place will quickly go underwater.

Especially in the low-lying coastal regions created by landfills in the past(eg Bkk).

 

Same applies to the one in Tokyo, Japan.

 

When you feel any major quake while in such a place, dash out immediately after the quake stopped. 

Well before the underground facility is flooded.

Once power supply is cut and the pumps are dead, that system will be doomed.

Modern public transportation built to reduce road traffic in the capital of this  kingdom.

 

Since 1980-90s, Bkk was often regarded the metropolis with the worst smog and road congestion in the world.

It even worsened after Thaksin govt't car ownership promotion started around 2000.
