BACK TO PROJECTS

The High Line is an iconic elevated freight line park that runs from the Lower West Side of Manhattan up to 30th Street.  The park is 20-30 feet above street level and as a result, many conventional maintenance strategies are not applicable to the site.  Even daily tasks, such as uploading trash or bringing materials onto the freight line, can prove problematic.  Moreover, the nature of the structure and the design greatly restrict the use of vehicles on site.  With these and other site restrictions in mind, ETM advised the landscape architecture office of James Corner Field Operations on potential design and maintenance concerns.

 

A prime example of ETM role was the revision in design of the proposed peel-up benches.  Initial plans called for the entire bench to be constructed as one continuous length of concrete that would run 12 feet long or more.  After diligent research, ETM determined that when the bench begins to deteriorate, the only way to replace it would be to shut down the street and rent a five-ton crane to lift the new material onto the site.  Without compromising the integrity of the design, ETM advised replacing the seating portion of the bench with traditional slats, thus allowing ease of material delivery and replacement.

 

In addition, ETM advised on the design of park maintenance facilities and special equipment needs.  Some of these recommendations included planning for lifts would be required to hoist materials and supplies from street level, garbage chutes that enable direct delivery of trash to street level, and small mobile units, such as golf carts and bicycles, outfitted for maintenance work.
