LONDON CITY AIRPORT

OVERVIEW

OVERVIEW

The initial scheme was for the removal of a concrete dolphin within the KGV dock to allow for the proposed expansion of the airport terminal and stands. Following on from the successful Dolphin removal a further £4.5m worth of work was instructed including landside civils, drainage, sub surface cable installation, dredging and marine support to UXO clearance teams.

THE CHALLENGE

For the dolphin removal a short construction period, with height restrictions on cranes, underwater demolition techniques and the proximity to live pedestrian routes and aircraft stands called for extensive planning of the project before arrival.

THE SOLUTION

A 3D model was created of the working environment to allow for works to be visualised effectively and planned to minimise risks and manage conflicts. A barge with crawler crane were mobilised and a series of design checks and calculations meant the crane could operate at much higher capacities then would normally be allowed for a demolition project or for floating plant. This attention to detail before arrival on site meant the scheme was completed ahead of an already tight schedule.
