BIM Modelling

Building Information Modelling is becoming increasingly vital for modern construction projects. Not only does it provide a digital representation of a building project, it also allows facilitates greater levels of collaboration and interoperability within the design environment. 

Building Information Modelling (or BIM as it is commonly known) covers a range of elements including geometry, graphical information, spatial relationships, product/material information and quantity information. As such the use of a 3d BIM model is not merely restricted to architects or design engineers and is also useful to project management, cost management, manufacturing and construction teams and also the facilities management teams who are the eventual owners of such models. 

One of the key differences between modern BIM technology and traditional software is that BIM software is written and developed for the design of buildings and their components. The objects created within BIM models represent actual elements within a construction project and therefore this information becomes more useful to designers, installers and cost consultants. 

At XS CAD, we create BIM Models using Autodesk Revit software. Autodesk Revit is a multi-directional, database controlled application which allows changes in one location to be replicated automatically in all other areas where the changed item appears (including layouts, elevations, schedules or the 3d model itself). 

By using Autodesk Architecture, Autodesk MEP and Autodesk Structures, we are able to create design data for a single construction project with the same family of software. This level of interoperability provides obvious time and cost benefits but also allows the entire project team to view the impact of their individual designs with those of others and to resolve conflicts based on this knowledge. 

As part of our BIM service we are able to maintain all elements of a BIM model within our 
Integrated Project Delivery approach or provide a BIM service to one party involved in a BIM project but without the expertise for BIM model creation and management. 

As part of our BIM Modelling service we also create BIM or family data for Revit Architecture and Revit MEP. This data encompasses physical and graphical elements as well as technical and manufacturer information for the element being modelled. Another key benefit of BIM models are the parametric properties and family properties assigned to models. Parametric modelling allows controlled and dynamic manipulation of models. This allows models to be changed quickly and easily within their range of parameters while also maintaining physical appearance and ‘model information’ within all areas automatically.
