- Functionality and Effectiveness - Buildings designed to meet the needs of the occupiers; effective, productive working environments
- Environmental - Meet Government performance targets in energy efficiency, water usage and waste production
- Facilities Management - A clear, cost efficient strategy for managing the operations of the building
- Commissioning, Training and Handover – Projects delivered, handed over and supported to meet the needs of the end user
The information to support many of these metrics is provided via the BIM information model, delivered through the information exchanges at the prescribed points identified in the Employer’s Information Requirements (EIR). The standard requirement is for five exchange points, identified in Figure 2.
There will be further asset-related information exchanges with the asset owner/operator, dependent on the nature and number of event triggers and asset management contracts or works.
There are other areas where BIM and Soft Landings fit hand-in-hand. The modelling techniques used for BIM provide an ideal environment for regular reality checking throughout the design process. Potential design solutions to high risk elements can be tested within the 3D modelling environment before any physical work is undertaken.
In the run up to handover, the model can also be invaluable in training facilities management personnel and maintenance staff. As well as familiarising them with the internal arrangement of the building via walk-throughs, maintenance tasks can be planned in advance and any potential issues addressed before the tasks are actually carried out for real. This can provide the time to develop safer ways of working without putting any
operatives at risk.
The information set produced when an asset is delivered is much wider than the graphical model, and should include supporting documentation which led to the final built solution, such as design reports, surveys and correspondence with the local authority about planning and operating licence conditions. Not all of this documentation is required to be available for day-to-day operation. However, it should still be accessible if more strategic or fundamental activities are to be carried out.
For daily asset operations a focused information set should be made available which also acts as the single source of information for the wider operation of the asset – any other information need should be supplied from this verified and validated data set, ensuring that decisions are made using the latest and most accurate information.
One of the aims of Soft Landings is to help close the performance gap through a managed approach to the design and construction of the building, focussed on the client’s objectives. The effectiveness of the measures adopted is assessed through the Soft Landings process by comparing the performance in use with the design values and other metrics through a series of post occupancy assessments. The data maintained within the BIM information set will act as an important source in making that judgement, with figures for metrics such as energy consumption and floor area readily available.
