A series of PAS documents set out the requirements for achieving BIM Level 2 by establishing a framework for collaborative working and information requirements.
As a whole the series currently contains:
- PAS 1192-2: 2013, which deals with the construction (CAPEX) phase, and specifies the requirements for Level 2 maturity; sets out the framework, roles and responsibilities for collaborative BIM working; builds on the existing standard of BS 1192, and expands the scope of the Common Data Environment (CDE).
- PAS 1192-3: 2014, which deals with the operational (OPEX) phase, focussing on use and maintenance of the Asset Information Model, for Facilities Management.
- BS 1192-4: 2014, technically a code of practice rather than a specification standard, which documents best practice for the implementation of COBie.
- PAS 1192-5: 2015, a specification for security-minded building information modelling, digital built environments and smart asset management.
The following documents, which will form part of the framework, are currently in production:
- PAS 1192-6 - a specification for collaborative sharing and use of structured health and safety information using BIM. Due September 2017.
- PAS 1192-7 - Construction product information - Specification for defining, sharing and maintaining structured digital construction product information. Due late 2017.
What's the difference between a PAS and a British or international standards?
Publicly Available Specifications (PAS) are rapidly-developed standards, specifications, codes of practice or guidelines.
A PAS is developed to meet an immediate market need and follow guidelines set out by the British Standards Insitution (BSI). After two years PASes are reviewed to determine if they require revision, should be withdrawn or become formal British or international standards.
The PAS 1192 framework in more detail
PAS 1192-2: 2013 Specification for information management for the capital/delivery phase of construction projects using building information modelling
The requirements within PAS 1192-2 build on the existing code of practice for the collaborative production of architectural, engineering and construction information, defined within BS 1192:2007 + A2:2016.
BS 1192 provides a ‘best-practice’ method for the development, organisation and management of production information for the construction industry. To this end it sets out a disciplined process for collaboration and a specified naming policy. It contains a template for common naming conventions and describes approaches to collaborative working for use in architecture, engineering and construction. Adopting the methodologies will also facilitate efficient data use in facilities management. The principles for information sharing and common modelling outlined in this standard underpin the BIM Level 2 standards and are applicable to building and civil engineering projects.
PAS 1192-2, meanwhile, focuses on project delivery. This is where the majority of graphical data, non-graphical data and documents, known collectively as the Project Information Model (PIM), come together.
It details requirements, starting with a statement of need, across the five stages of information from procurement, through post-contract award, mobilisation, production and maintenance of the Asset Information Model (AIM) as part of handover.
At the heart of the approach is the idea of "beginning with the end in mind" - identifying later uses of information collected from the start to ensure appropriate use across the entire lifecycle of the built asset. As such, PAS 1192-2 is of interest to those responsible for the procurement, design, construction, delivery, operation and maintenance of buildings and infrastructure assets.
PAS 1192-3: 2013 Specification for information management for the operational phase of assets using building information modelling (BIM)
PAS 1192-3 provides guidance to asset managers on how to integrate the management of information across the longer term activity of asset management with the shorter term activity of asset construction for a portfolio of assets.
PAS 1192-3 should be read in conjunction with PAS 1192-2.
PAS 1192-2 specifies an information management process to support BIM Level 2 in the capital/delivery phase of projects. In contrast, PAS 1192-3 focuses on the operational phase of assets irrespective of whether these were commissioned through direct capital works, acquired through transfer of ownership or whether they already existed in an asset portfolio.
However, like PAS 1192-2, PAS 1192-3 applies to both building and infrastructure assets and is based on the existing code of practice for the collaborative production of architectural, engineering and construction information that is defined within BS 1192:2007 + A2:2016.
PAS 1192-3 has been developed in recognition of the fact that the cost of operating and maintaining buildings and facilities can represent up to 85% of the whole-life cost, and savings can pay back any upfront premium in construction expenses in a few years.
BS 1192-4: 2014 Collaborative production of information. Fulfilling employer’s information exchange requirements using COBie. Code of practice
BS 1192-4 outlines the UK usage of COBie, an internationally agreed information exchange schema for exchanging facility information between the employer and the supply chain.
This code of practice defines expectations for the exchange of information throughout the lifecycle of a Facility. The COBie (Construction Operations Building information exchange) provides a common structure for the exchange of information about new and existing Facilities, including both buildings and infrastructure. The use of COBie ensures that information can be prepared and used without the need for knowledge of sending and receiving applications or databases. It ensures that the information exchange can be reviewed and validated for compliance, continuity and completeness.
PAS 1192-5: 2015 Specification for security-minded building information modelling, digital built environments and smart asset management
PAS 1192-5 specifies requirements for security-minded management of BIM and digital built environments. It outlines the cyber-security vulnerabilities to hostile attack when using BIM and provides an assessment process to determine the levels of cyber-security for BIM collaboration which should be applied during all phases of the site and building lifecycle.
PAS 1192-5 is of relevance to any organization working with building information modelling, digital built environments and smart asset management. The approach outlined in this PAS is applicable not only to projects employing BIM and the implementation and use of smart asset management, but to any built asset where asset information is created, stored, processed and viewed in digital form. It is also applicable to the capture of digital survey data as part of the day-to-day asset management processes or in anticipation of a future project.
The PAS addresses the steps required to create and cultivate an appropriate security mindset and secure culture within an organization, including the need to monitor and audit compliance.
