In preparation for the 2012 London Olympic Games, Erith were employed to undertake the demolition and dismantling of a number of existing bridges within what was to become the Olympic park site.
Bridges were sited over the existing canals and roadways, presenting an array of environmental challenges.
Environmental constraints working over a waterway meant that all structures would have to be dismantled, with access from the bankside or from pontoons moored under the bridge. No arising would be allowed to fall into the canal, so the demolition methods were carefully chosen to maintain the integrity of the watercourse.
These were comprehensively written and submitted to the ODA and their consultants for approval before any works would be allowed to start. Removal of the bridge deck was completed as a whole component and this meant contracting intricate craneage that would be up to the task.
Hard standings were created and tested prior to rigging of the crane and all were engineered by our temporary works consultants. Demolition of the bridge decks could then be carried out away from the canal or roadway.
Safety boats were on hand during the works for the protection of the workforce, with control measures put in place to monitor working at height to ensure the highest standards of health and safety.
Successful delivery of these works was only possible after careful planning and consultation with the client, waterways and Highways authorities.
