PROJECT OVERVIEW

“HIGH LINE”

(High Line,Tyson Motsenbocker | Songwriter: Tyson Motsenbacker)

 

Holding Up the High Line

SAFELY EXCAVATING BELOW A POPULAR ELEVATED PARK

The High Line elevated railroad was constructed in the 1930s to eliminate dangerous street-level railroad crossings, while maintaining essential freight deliveries to lower Manhattan. In 2005, 25 years after the last train ran on the line, the remaining structure was repurposed and converted into a very popular park. GEODesign was retained to design a complete High Line structural support system for the construction of a new deep building cellar.

Holding Up the High Line

The cellar level for this project was significantly constrained by the 100 year flood zone, the curving nature of the High Line, and the existing High Line foundations.  It was decided that removing the existing foundations and extending the High Line columns through the cellar would result in a much more efficient cellar layout.  This required the design and installation of an extensive and complex temporary support system to carry the High Line loads.
