Project Description

As part of the Saski Business Park development, which includes the construction of two office buildings between Marszalkowska and Krolevska Street in Warsaw, three century-old chestnut trees had to be relocated to save them from destruction.

Because of their size and age, the trees could not be displaced using conventional transplantation methods. VSL`s innovative solution consisted in sliding the trees together with their entire enviroment in just one step, saving the roots from potentially fatal injury.

Before sliding, the trees were pruned and their trunks wrapped in rolls of jute bandages to reduce perspiration i.e. loss of water.

The first step of the project consisted in excavating the earth around the chestnut trees and additionally over the sliding distance between 18 and 32m.  To avoid the decompression of the ground and maintain the roots in their original environment, temporary steel and wooden retaining walls were erected to form two giant pots. The average sliding speed was 4m per hour.
