Staged success of a viaduct replacement |
 | The Newmarket Viaduct Replacement project combines staged construction with deconstruction of the existing viaduct in the heart of Auckland, New Zealand. The staged approach allows the motorway to remain open to traffic throughout the project. This is the first time a bridge of this size has been taken apart in this way and VSL is part of the project alliance. | |

Design and build of TKO bridge in Hong Kong |
 | A joint venture between Kaden-VSL has successfully lifted the main span of the Tseung Kwan O bridge in Hong Kong. VSL has designed a modular truss system to erect the bridge, whose deck is supported on arch piers that cantilever 10m from the pile cap. The system was first used to build the arch supports before being modified and repositioned for use in lifting the 1,600t deck. | |

Top trusses for Central Government Complex |
 | VSL has lifted six ‘mega trusses’ totalling 2,560t for Hong Kong’s prestigious Central Government Complex. Each of the three 17m-high and up to 58m-long trusses was lifted by 100m in two operations. Target speed was 12.5m/h to allow completion of each lift in a single day in compliance with noise permits. | |
