Modern port design is a complex, multi-disciplinary exercise that deals with all aspects of a project, from the geological assessment to wharf construction. A general contractor has to facilitate the work of a wide number of engineering and construction teams. A wide range of disciplines must be covered: geology, geotechnical analysis, hydraulic design along with construction design.

Building information modeling refers to a digital knowledge base describing physical and functional aspects of buildings. Often referred to simply as BIM, not to be confused with bam, pow, zowie from the 60’s Batman TV series, this knowledge base serves to manage a building throughout its lifecycle, from initial design right through to renovation or demolition, enabling huge savings in construction costs to be achieved.
Part and parcel with model-based engineering is model translation. Because the model is now the specification, accurate translation from one system to another becomes essential. But even if a model is accurately read, the intent of the model has to also be properly interpreted. Key to proper model interpretation is healing — the process of modifying model data so that it conforms to the rules of the target system, while adhering to the intent of the source.
In a past blog, The Impact of Model-Based Definition (MBD) on 3D Modeling and Manufacturing, we discussed the growing role of MBD. To recap: although 3D modeling has been the standard in design for decades, many manufacturers still rely heavily on 2D drawings when communicating with suppliers. MBD enables the next step in CAD evolution where the 3D model becomes the means of communicating manufacturing data and specifications (product and manufacturing information or PMI).
As water jet and laser cutters become more sophisticated, the geometries that they are able to cut are also increasing in complexity. In recent years, the ability to angle cutting heads has meant that instead of being restricted to vertical cuts, bevel cuts now become possible.
