The Soil That Shifted: A Geotechnical Forensic Study of 161 Maiden Lane

An engineering post-mortem examining why 1 Seaport developed a documented 3-inch northward lean during construction. We analyze the 155-foot depth to Manhattan schist bedrock, the fatal economics of choosing jet grouting over driven steel caissons, and the resulting curtain-wall shear failure.
