INSULATION The government mandated that all A model’s for life, not just for 2016 Digital working is increasingly becoming more commonplace throughout the construction industry, but Building Information Modelling (BIM) is about more than making 3D models. It is an approach to project builds with the aim of collaborating with all relevant parties to allow greater efficiencies to be identified in procurement, build, and in life-cycle use. So, how does this make the market better? Adrian Pargeter, head of technical and product publicly-funded projects should be utilising BIM level 2 by April 2016. The expectation is that every business involved, from the architects sketching up plans to the contractors considering how to manage the building’s end of life, should have access to that wealth of information. BIM, which is more frequently being referred to as ‘digital construction’ as a catch-all for the evolution of construction methodologies, aims to facilitate effortless access to a detailed model of the building which allows parties to manipulate or interrogate data. It carries the potential to achieve significant savings in both materials and time, and to track as-built performance, providing valuable information which will also benefit later projects. The modelling process makes it easy to identify quantities, such as the impact of changing different components of the building envelope or services. It can define the best logistical sequences 050 APRIL 2017 RCIMAG.COM development at Kingspan Insulation gives his view of the construction process and optimise the maintenance and operation of the building. In short, when used properly and collaboratively as intended, BIM has the potential to cut costs, improve quality and drive lifetime efficiency – all elements that are essential to the recovery, growth and future development of the industry. Contractors need to understand the importance of BIM, especially since the industry should now be taking steps to ensure they are ready for implementing level 3 by 2025 on government contracts. When fully embraced, BIM will help to keep costs down, keep a project on track and keep clients satisfied. Clients are invaluable in helping to shape the specification and programme, and their early involvement can contribute towards identifying the optimum balance between cost, ease of installation and performance. Knowing the benefits of adopting BIM, and making use of them, will help contactors find simpler and more efficient solutions for construction processes. Not all objects are made equal One of the key attributes of BIM modelling is the ease with which the impacts of introducing different product types can be examined. These impacts might include building performance or operational costs. The product types are represented by ‘objects’ which are dropped into the BIM programme to provide performance data. These objects can be generic, but many manufacturers now offer specific product objects to provide far more detailed and accurate information. Whilst generic objects can go a long way towards reaching overall building performance levels, it is the information relating to actual products that will help to swing specification when the design gets down to the fine detail. Construction industry bodies work towards the standardisation of information that manufacturers provide. By doing so, data can be more accurately compared to determine which materials or build-ups are the best value for the project. In addition to this, it also offers learning opportunities and a chance to inform future builds. Consistent formatting, for example, ensures that end users know what to expect when using BIM. It makes it much easier to interrogate data, which will ultimately save time when trying to find the most appropriate materials for the Evolution “Clients are invaluable in helping to shape the specification and programme, and their early involvement can contribute towards identifying the optimum balance between cost, ease of installation and performance” Left: 3D View of the Kingspan Insulation offices in Pembridge created in Revit using BIM objects
