Improving digital data and information management within the built environment through the implementation of Building Information Modelling (BIM) offers significant benefits to whole life performance of the Public Sector estate.
In October 2012, the Scottish Government launched a review of public sector construction procurement. The review, led by Robin Crawford and Ken Lewandowski, published its report the Review of Scottish Public Sector Procurement in Construction on 22 October 2013. The review identified the benefits in adopting BIM and made the following recommendations in how the Scottish Government and procuring authorities should adopt BIM.
The use of Building Information Modelling (BIM) should be introduced in central government with a view to encouraging its adoption across the entire public sector. The objective should be that, where appropriate, construction projects across the public sector in Scotland adopt a BIM level 2 approach by April 2017.
In response to this and as part of the wider public procurement reform, Scottish Futures Trust in partnership with Scottish Government were tasked in delivering this recommendation. The journey to BIM level 2 adoption by April 2017 and the implementation process was set out within the Scottish BIM Implementation Plan published in Sep 2015. This set out focused actions including pathfinder projects, guidance and training which was delivered in partnership with industry.
As Scotland moves towards a digital built environment, BIM is seen as a key part for the future of the Scottish construction industry. BIM uses digital technology to improve the sharing and analysis of data within a construction project. Through improving data management and collaboration within projects, this will support the industry to deliver greater efficiencies through the design, construction and operational stages of a project. BIM Level 2 is the next step in the digital journey and is defined by the Home Nations Working Group as:-
BIM Level 2 maturity encompasses the generation and management of structured information models comprising all named data-sets used throughout the lifecycle of a built asset.
Information models will include a series of domain and collaborative federated models. The models, consisting of both object-oriented 3D geometrical and non-graphical data, are prepared by different parties during the project life-cycle within the context of a common data environment. Using agreed information exchanges, project participants will have the means necessary to provide defined and validated outputs via digital transactions in a structured and reusable form.
Appropriate and proportionate measures will be applied to manage the security risks that affect a built asset, asset data and information.
This definition of BIM and the associated British Standards are already developed for industry. The standards include:-
- BS 1192:2007 + A2:2016: Collaborative production of architectural, engineering and construction information. Code of practice
- PAS 1192-2:2013: Specification for information management for the capital/delivery phase of construction projects using building information modelling
- PAS 1192-3:2014: Specification for information management for the operational phase of assets using building information modelling (BIM)
- BS 1192-4:2014: Collaborative production of information. Fulfilling employer’s information exchange requirements using COBie. Code of practice
- PAS 1192-5:2015: Specification for security-minded building information modelling, digital built environments and smart asset management
- BS 8536-1:2015: Briefing for design and construction. Code of practice for facilities management (Buildings infrastructure)
- BS 8536-2: 2016: Briefing for design and construction, Part 2; code of practice for asset management (Linear & geographical infrastructure)
The Scottish BIM guidance contained within this website fully aligns with and promotes the standards listed above. For further information in relation to the standards and BIM definitions, refer to our resources section. This guidance provides the public sector procuring authorities the guidance and resources to implement BIM and realise the benefits it will bring.
