One of the benefits of adopting BIM is the potential for better avoidance of clashes, that is, it can help ensure there is spatial co-ordination between the different components that make up the asset.

−	For example, avoiding situations on site such as the route for pipework running through a steel beam (sometimes described as a ~~‘hard clash’~~), which can be very difficult, disruptive and costly to rectify. Clashes can also occur as a result of construction tolerances, too little space to install or maintain a component of the building, the installation of insulation, proximity clashes, health and safety requirements, or from too many workers being programmed to carry out works in the same space at the same time. These are sometimes described as 'soft clashes'.	+	For example, avoiding situations on site such as the route for pipework running through a steel beam (sometimes described as a 'hard clash'), which can be very difficult, disruptive and costly to rectify.

−	Clashes can be a particular issue where multiple disciplines are working on different aspects of the same project. Whilst in theory, BIM should reduce clashes by bringing together the entire design team to work on one collaborative, co-ordinated building model, BIM Level 2, allows disciplines to work on separate ~~‘federated’~~ models that are only brought together to create a single, complete model of the building at key stages. The building information model may also be broken down into volumes to allow more than one person to work on project models simultaneously, or to ensure that file sizes are manageable. This increases the likelihood of poor spatial co-ordination.	+	Clashes can be a particular issue where multiple disciplines are working on different aspects of the same project.

		+	Building information models are likely to comprise a series of federated models prepared by different design teams, including model files, documents and structured data files containing non geometric information about the facility, floors, spaces, systems and components. Together these create a digital replica of the built asset that starts by representing design intent, but by handover, reflects what has actually been built and installed.
