π Snapshots of Life: A Visual Diary of My Journeys
1993 β The Daecheon Seawall
2009 β Life Savior: A Sixteen-Year Jump
It began with a question from a supervisor at the Cheonan wastewater treatment plantβan engineer from the city hallβasking if I had any interest in the sluice gate control system of the Daecheon seawall. His high school friend, an electrical manager at Daesan Construction, was preparing bids for the project near Jupo-myeon, close to Daecheon.
Back then, before Daecheon was renamed Boryeong, the county and the city were separate jurisdictions. I drove from Cheonan to the site and met the man in charge, Kim Chunghwan, three years my senior. Despite his rugged appearance, he was a delicate soul, tending to two hundred orchids at home. We became closeβsharing drinks, meals at his house in Sapgyo, and eventually calling each other brother.
That project of 1993, grueling and tangled, would resurface sixteen years later, during the collapse of Lehman Brothers. When North Americaβs economy fell apart and jobs vanished, it became my salvation. I was dispatched to the field once more, enduring hardships beyond words, yet earning steady income and gathering invaluable experience. It was the bridge that carried me back to Hatch, my rebirth after bitter departure.

At that time, Korea was narrow in land, and the West Coast was a theater of immense reclamation projects. The Daecheon seawall was part of this grand effortβsecuring farmland, irrigation, and protection against tidal waves. The client was the Rural Development Corporation of Chungnam, the builder Daesan Construction, and the operator the Daecheon Farmland Improvement Association.
The sluice gates: twelve in total. Eight in the north, four in the south, each massive steel structures five meters wide, three meters high, weighing tens of tons. They held back the sea at high tide, released freshwater at ebb tide, and balanced floods by storing and discharging. Yet the challenge was immense: corrosion, leakage, and the delicate precision required to lift such weight without damage.
The old winch-driven system could not seal tightly enough; seawater seeped in, threatening farmland with salt damage. Thus, hydraulic cylinders were introduced for fine control. But in the design process, a crucial on-site control unit was omittedβa mistake discovered only after contracts were signed. What we had bid for was simple remote operation and monitoring, not the intricate hydraulic control itself.
The contract became a trap. What should have been a straightforward PLC interface suddenly transformed into a complex hydraulic control system. With budgets stretched thin, we forced an impossible subcontract at absurdly low cost. My colleague, Deputy Manager Min, suffered alongside meβhis voice in karaoke as poor as his luck in this projectβboth of us ground down by endless site problems and company scorn for low-bid contracts.

It was a project so bitter that I swore never to set foot in Daecheon again. Yet, sixteen years later, in the autumn of 2009, it became the very reason I survived. Amid the wreckage of the global financial crisis, when seventy percent of projects were canceled and countless engineers sat idle, only three were chosen for field assignment. Out of fifteen waiting, I was selectedβnot because of tenure, but because of my hard-won experience with hydraulic gate control.
That knowledge, born of suffering, became my lifeline. For over two years, including a year on-site, I endured and prevailed.
Oh Lord!
