In order to restore the monumental bridges of the Akerendam estate in 2016, a contractor placed dams in the canal to pump the water away from under the bridges. As a result, the load-bearing sand layer was washed away under part of the retaining wall. ToornendPartners offered the owner a temporary solution to remedy the damage in close consultation with those involved and claimed the damage from the insurance. Subsequently, ToornendPartners consulted new experts. Together they found a final solution and implemented it. It was precarious work because it was carried out entirely under water.
