Not Muzak

At our offices on the campus of the Ministry of Public Health, outdoor loudspeakers sometimes broadcast background music—pleasant, traditional sounds, usually a woman singing softly. Never a loud guitar, never an advertisement. The kind of thing you might hear at a trendy cafe.

So it’s been quite a jarring and reverberating change to have big construction happening next door. We’re treated throughout the day to the poundpoundpound of a giant hammer, several stories tall. This device whacks its business end against an eighteen-inch-wide, one-hundred-foot-high cement chopstick, again and again and again, until only a tiny fraction of the piling is still visible above the ground. Then the huge machine rolls a few feet and clobbers a new piling, overandoverandover.

Hundreds of pilings await their turn to be brutally pummeled into the earth. Why not drill many holes first, and then bury these long poles that will become the foundation of a future building? Because apparently you have to dig a long way down in Bangkok before you reach anything that can be considered solid. The Earth’s crust in this corner of the continent—once known as the “Venice of Asia”—is mostly muck. We’re talking sea level and below! Can you say “water table?” Can you say “we’re sinking!?”

No wonder nobody in this town props up their structures on rectangles of concrete. Instead, every new project, from simple garden wall all the way up to high-rise hotel, starts with the pounding of pilings. That way, the finished product has a pretty good chance of staying level.

The engineer who explained all this for me also solved a mystery that had been bugging me for some time: he said that Bangkok’s sidewalks crinkle because they rarely have pilings underneath them. Unlike the buildings they pass in front of, the sidewalks float on the city’s slurry soil. That’s why they often consist of small pavers or bricks instead of poured cement blocks, and why it’s not unusual to see large gaps form between the sidewalks and the steps of buildings.

Some day I’m sure we’ll forget these few weeks of trying to tune out what sounds like a hardcore punk rock club next door. Today, I’d rather have Muzak.
