BIM Level 2

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.

BS 1192:2007 + A2:2016

Collaborative production of architectural, engineering and construction information. Code of practice

BS 1192 provides a ‘best-practice’ method for the development, organization and management of production information for the construction industry, using a disciplined process for collaboration and a specified naming policy.

It provides the template for common naming conventions and approaches to collaborative working for use in architecture, engineering and construction. It also facilitates 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 equally applicable to building and civil projects.

BIM Level 2

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.

PAS 1192-2 focuses specifically on project delivery, where the majority of graphical data, non-graphical data and documents, known collectively as the project information model (PIM), are accumulated from design and construction activities.

The intended audience for this PAS includes organizations and individuals responsible for the procurement, design, construction, delivery, operation and maintenance of buildings and infrastructure assets. Where possible, generic language has been used, but where necessary, specific definitions are included.

BIM Level 2

PAS 1192-3:2014

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 is a partner to 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 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. It is envisaged that cost savings of 33% can be achieved across the CAPEX and OPEX phases through implementation of the processes outlined in PAS 1192-2 and PAS 1192-3.

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.

BS 8536-1:2015

Briefing for design and construction. Code of practice for facilities management (Buildings infrastructure)

BS 8536-1:2015 gives recommendations for briefing for design and construction, to ensure that designers consider the expected performance of a building in use. The standard applies to all new buildings projects and major refurbishments.

BS 8536-1 aims to:

  • Involve the operator, the operations team and their supply chain from the outset
  • Extend the involvement of the supply chain for the project’s delivery through to operations and defined periods of aftercare

The scope of the revised BS 8536-1 has been expanded to include briefing requirements for soft landings, building information modelling (BIM) and post occupancy evaluation (POE).

Mark Bew, Chairman of the UK Government BIM Implementation Group says that “The Government has a vision to reduce whole life costs of assets by 33% by 2025, and the revision of BS 8536 incorporating the principles of GSL (Government Soft Landings) will ensure that it will become one of the key guidance documents, alongside PAS 1192-2, PAS 1192-3, PAS 1192-5 and BS 1192-4 to achieve this aim in both the private and public sectors”.

BIM Level 2

BS 8536-2:2016

Briefing for design and construction. Code of practice for asset management (Linear and geographical infrastructure)

BS 8536-2:2016 is part of the BIM level 2 suite of documents developed to help the construction industry adopt BIM. It gives recommendations for briefing for design and construction in relation to energy, telecommunication, transport, water and other utilities’ infrastructure toensure that design takes into account the expected performance of the asset in use over its planned operational life. It is applicable to the provision of documentation supporting this purpose during design, construction, testing and commissioning, handover, start-up of operations and defined periods of aftercare.

The new standard adopts the structure and format of its companion document, BS 8536-1:2015, and as such incorporates the principles of briefing associated with BIM Level 2 and Government Soft Landings.

BS 8536-2 is the only standard to provide briefing recommendations for the design and operational performance of infrastructure assets. It provides an evidence based approach to design and construction, coordinating recommendations, not just from the asset management standards (ISO 55000 series), but also the BIM PAS’s 1192-2, -3 and -5, and Government Soft Landings.
