Sandwiched between the Clyde and Forth Canal and residential properties, the Dundas Hill site presented significant logistical challenges for both the remediation processes and the material management techniques we employed on site.
The site was subject to low level asbestos and hydrocarbon contamination, so we undertook watching briefs and incorporated dust suppression equipment and techniques into our materials crushing and handling processes.
We remedied the areas of contamination by utilising the redundant basements below the development level to encapsulate the contaminated material under no dig membranes, before completing with a clean capping material of site won material to the finished platform level.
This approach, alongside our site wide materials management strategy, meant we were able to retain all excavated materials on site as part of a clean capping layer with bituminous planings retained for reuse as an unbound subgrade material.
