Makati Shaft Site — February 24, 2024 | 8:45 AM
Beneath the skyline of Makati, where finance towers and condo developments brushed against the morning haze, Sentinel's engineers stood deep in the belly of the city. The Makati shaft—Segment 3 of the MMSP—was one of the deepest bore points in the entire project. Nearly 50 meters down, workers braved narrow corridors of rock and reinforced concrete, guided only by floodlights and instinct.
Matthew stepped out of the site elevator, helmet clipped under one arm, safety glasses already fogged from the descent.
Angel was waiting at the base, headset active. "Geothermal scan's been cleared. TBM Aurora passed its pressure test. We can start carving the Makati corridor by next week."
Matthew took it all in. Reinforced columns, backup power lines, automated stress monitors blinking in orange and green. They were building a city beneath a city.
"How's the vibration profile?" he asked.
