BIM - Our Approach and Benefits
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 Modeling 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.
Why Banyards use BIM...
- Improved collective understanding of design intent. Most project owners believe this and rank it as the highest area of value, as they can use models to better understand and monitor ideas that carry through the lifecycle of a project.
- Integration with Building Physics modelling. We are able to integrate federated design models into other software packages to challenge and test our evolving solution for daylight, energy and environmental performance.
- Coordination and clash detection made easier. Working closely with our design partners we can minimise plant space allocation whilst ensuring all systems and services can be easily installed and are fully maintainable. We can minimise additional secondary or trimming steelwork by sharing our models and collaboratively resolving any conflicts.
- Reduced changes & conflicts during construction. BIM reduces re-works, as it helps teams avoid costly changes on site affecting both budget and the program.
- Elemental costing & scheduling made easier. Our models can be converted into schedules with quantities, and products & equipment can be switched for alternatives at the click of a button. This information can be exported for use by the cost consultant to determine an accurate M&E cost.
- Reduced claims and disputes. Answering more questions early in the project helps eliminate the grey area that will cause problems later. Increasing predictability of projects can help reduce future claims and disputes.
- Operational cost savings. The final model handed over to the FM team is rich with useful data which will enable the building operator to maximise the performance of the asset. This will reduce ongoing planned maintenance costs and ensure the building users benefit from a first class working environment.
Level 3 Building Information Modelling – Strategic Plan
This strategy represents the outcomes and recommendations for the next stage of the Building Information Modelling journey, building on the standards and savings being delivered by the BIM level 2 initiative. Level 3 will enable the interconnected digital design of different elements in a cloud environment and will extend BIM into the operation of assets over their life cycle.
With the full range of services Banyards are able to offer we have already started our journey to deliver Level 3 BIM and are looking for likeminded industry partners to team up with to stay at the forefront of this exciting time for the construction industry.
