PAS 1192-3: BIM for Asset management

PAS 1192-3: the “codes of practice” issued through simplified procedures to quickly meet real estate management requirements

The need for a profound re-invention of production processes has been felt as a requirement by all industrial sectors in order to greatly improve their current productivity and efficiency levels.

In relation to this need, there has recently been a radical and widespread change in industrial policies, with the growth and development of innovation and digitalisation of traditional workflow processes.

For the construction sector, BIM (Building Information Modeling) has been identified and considered as the gateway to digitization.

Among the various nations that more than any other have believed and invested in this process, the United Kingdom has played and plays a significant role in the international scenario.

The first government mandate, issued by the UK government in 2011, introducing BIM and its mandatory use (currently at Level 2) in public procurement starting in 2016, was followed by an update with a “vision” of evolution for up to 2025. As a consequence of this strong political push, a broad production of guidelines and technical regulations was followed to accompany the entire sector in this transition.

The British Standard Institution (BSI), the oldest Anglo-Saxon institution in the world, has produced a substantial and organic production of technical legislation, which has been widely circulated internationally.
Some of these rules have even been made available for free just to encourage the dissemination of the new methodology and the relating processes: among these, the well-known PAS 1192 parts 2 and 3.

PAS 1192 parts 2 and 3

PAS (Publicly Available Specification) is not a true BS standard, but can be considered as a kind of practice code, enacted through simplified procedures to quickly meet emerging needs. They are subject to review every two years and can be promptly withdrawn by the British Standard Institution.

PAS 1192 parts 2 and 3 are conceived as related, being 1192-2 related to the design and construction phases of a building (“Specification for information management for the capital/delivery phase of construction projects using Building Information Modelling”), while 1192-3 relates to the phases of its useful life (“Specification for information management for the operational phase of construction projects using Building Information Modeling”). See figures 1 and 2.

At the center of both documents, we also have “maps” that depict the evolution of a building, from initial financing to design, construction, maintenance, leading to final restructuring through to its disposal. See figures 3 and 4.

The diagram (figure 4)proposes a wider representation of the asset’s operating phase, because the latter is much more relevant than the first, from a time-scale point of view.

The two diagrams represent the Common Data Environment (environment for sharing common data) where all the information relating to the building are stored and managed, and conveyed through its virtual models.

Steps from 1 to 6 represent the evolution of the design and its realization, and require the creation and development of the Project Information Model (PMI), ie the virtual design model of the construction.
Once the construction is completed, with the so-called“as built” model, phase seven begins, being the long phase of management of the built asset, with the transition from the original Project Information Model to the Asset Information Model (AIM).

Also note the change in slope of the line representing the development of the two models: the first section is very inclined, indicating a rapid growth of the information made available during the first part, whilst less sloped in the second section, to underline a slower evolution during the management of the built asset.
