The Government’s Construction strategy 2011 defined the need to “derive significant improvements in cost, value and carbon performance through the use of open shareable asset information”. This was the motivation behind the UK’s BIM Strategy and the 2016 Mandate to achieve Level 2 BIM maturity on all publicly procured construction.
BIM level 2 requires a collaborative working environment
As the UK’s BIM expertise and experience has evolved – starting with the early Avanti projects – an understanding has been developed that Level 2 BIM is not solely about 3D models – it is about the information management process and creating a collaborative working environment.
To achieve this collaborative working environment, information must be produced in a standardised process, to agreed standards and methods to enable the information to be used and reused without change or interpretation.
This has led to the definition of the Information Delivery Cycle
And as a result a number of Information Standards have been created:
- BS 1192: 2007 – Information Management
- PAS 1192-2 – Capital
- PAS 1192-3 – Operations
- BS 1192-4 – COBie
- PAS 1192-5 – Security
- CIC BIM Protocol – agreed deliverables / insurance
- GSL – Government Soft Landings
- Digital Plan of Work
- Uniclass Classification
Cadnet works in accordance with the above standards and aligned to the client’s requirements.
Typically client’s requirements cover the use of the Digital Plan or Works, PAS 1192:2 and PAS 1192:3; and increasingly BS1192:4 is requested as they are asked to deliver accurate handover data in COBie compliant formats.
The CIC Protocol and Government Soft Landings is applicable only to the project definition process.
