Building Information Modelling (BIM) - Taking design to the next level

Building Information Modelling (BIM) has been brought to the fore by the government’s construction strategy published in 2011. The strategy states all publicly funded construction work must be undertaken by using Building Information Modelling to Level 2, by 2016. This mandate is driven by the government’s commitment to reduce the cost of construction by 20%, by the next parliament.

The added value of the BIM process implemented on any building project is in its methodologies. It is not an out of the box product, but a collaborative process which enables better information to be provided at the right time, typically much earlier in the design process. Ultimately this will allow projects to be more accurately costed and reduce the associated risk. The design stage becomes more of an evolution, all the time embedding the strengths and efficiencies and ultimately reducing the long term life cycle impact.

For this to be achieved, high demand is put on clear collaborative engagement from the delivery team and the stakeholders. Briefs need to be clear or sufficient time allowed for the exchange of key design information and requirements. This is where Banyards can help you.

Level 2 BIM is defined by this clear collaborative approach. All members of the delivery team use their own 3D models which are then ‘federated’ (or coordinated) into a combined model with shared responsibility. This part of the process alone provides huge benefits to the professional design & construction team however it shouldn’t end here.

At this stage the level 2 BIM model is rich with design and performance data and product information that the building end user can use post-handover to operate, maintain and maximize the use of their asset.

The exchange of information from the professional design team through to the construction team and then onto the building operator is fundamental to realising the full benefits of Level 2 BIM regardless of the agreed common file format.

It is widely regarded that the BIM approach will filter into the private sector as the industry cost benefits become clear; current research suggests that these gains are demonstrable:

  • Up to 40% elimination of unbudgeted change.
  • Up to 80% reduction in time taken to generate a more accurate cost estimate.
  • Savings of up to 10% of the contract value through clash detections resolved prior to site.
  • Up to 7% reduction in overall project time.
