Synopsis

This book presents the development of the art of modern underpinning in the construction of New York City subways from 1900 to the mid-1910s. It provides a detailed, historical overview of the methods used to safeguard buildings during excavation work for new construction and subway tunnels. The authors highlight the need for innovative and effective techniques to minimize damage to existing structures and ensure their continued support despite deep excavations alongside. The evolution of methods is explored, from rudimentary shoring and needling to the introduction of horizontal sheeting, sectional pipe piles, and the use of concrete-steel grillages to reinforce and tie together individual foundations. Additionally, the book emphasizes the importance of a tight cut-off between the building and excavation to prevent the loss of soil and protect interior columns and basements. The development of these techniques is placed within the broader context of the construction of the New York subways, emphasizing their critical role in enabling these projects to proceed safely and effectively. The insights from this book remain significant for understanding the historical context and technical evolution of underpinning methods in the construction industry.
