CN3 carried out a full VDC solution for the design & build of the combined 2.1 km steel and concrete bridge including abutments and earthworks. All concrete structures onshore and offshore were modelled at information level LOD500.
During the design stage, all structural details and alignments were examined to make sure the client requirements were achieved and the level of constructability was enhanced in order to increase profitability.
During the execution stage the detailed models were used for digital fabrication of reinforcement bars, formwork, prefabricated concrete elements and setting-out data.
A thorough examination of the project based on the 3D models reduced the production rates, number of rework and waste material to a level as low as 0.06%.
The full 6D solution with an integrated planning system, an ordering system for foremen and an as-built model including tolerance documentation provided a return on the VDC investment close to 900%.
