If implemented correctly, Building Information Modelling (BIM) provides the solution for managing assets effectively. How you measure the benefits of BIM depends on your organisation's objectives as a client, or your purpose in the supply chain throughout planning, surveying, design, construction or asset management.
However, BIM has a number of overarching benefits for all organisations with respect to managing data, information and assets and saving money, energy and carbon throughout the construction life cycle.
An organisation's energy savings are highly dependent on your assets and activities. BIM enables effective data management for the measurement of Key Performance Indicators (KPIs) and organisation performance to help identify improvements in assets and operations to combat energy consumption, carbon emissions and additional costs. This can entail the implementation of a number of energy saving measures which can be maintained through BIM; building fabrics, building services, renewable technology, more efficient process plants, equipment and vehicle fleets and improvements to operations.
PAS 1192-2 sets out the specification for information management at the delivery phase of construction projects using BIM, outlining a collaborative framework and providing specific advice for data and asset management. By 'starting with the end in mind', clients should identify what they need and expect from their assets as part of their BIM solution, considering at an early stage in a project how implemented management systems will affect energy, carbon and cost. These decisions made at an early stage may initially increase costs, but will lead to greater savings later in the construction cycle.
PAS 1192-3 sets out the specification for information management at the operational phase of construction projects, supporting the BIM Level 2 objective to manage the entire life cycle of all built assets. All asset information is digitised through BIM, enabling a greater awareness of operations, maintenance, performance and expenditure to make more informed decisions and achieve better savings and information quality as a result.
A key example of the construction supply chain which can benefit from BIM in terms of saving energy, carbon and costs is the Energy Savings Opportunity Scheme (ESOS), which requires large organisations to identify and implement energy saving measures to meet legislative requirements and notify the Environment Agency (EA) of compliance every 4 years.
ESOS compliance can be achieved by demonstrating energy consumption calculations and maintaining their records and identifying energy saving opportunities. However, inefficient processes and site-based processes at the asset level can often lead to loss of information and data, in turn causing inaccuracies in these calculations and result in a more time consuming and less beneficial ESOS energy auditing process.
BIM can help organisations to make accurate calculations for Total Energy Consumption (TEC) and Significant Energy Consumption (SEC). Finding these results can enable effective management of assets such as buildings, processes, transport and client operations to meet ESOS audit requirements. BIM helps organisations and clients to identify and meet their Organisational Information Requirements (OIR) and Asset Information Requirements (AIR), enabling them to carry out construction projects. If correctly utilised the supply chain's response to these requirements can help to achieveing energy, carbon and cost reductions, if careful consideration of objectives is taking into account.
