The BIM and how to effectively manage the entire building life-cycle. Let’s go through the Specifications for information management for the operational phase of assets using Building Information Modelling (BIM) (part 2)
In the previous article we have illustrated the general principles of the PAS 1192 and how PAS 1192-2 is a partner to PAS 1192-3. Let’s now find out about the latest updates and PAS 1192 framework in more details.
PAS 1192-2 in conjuction to PAS 1192-3
The connection between the two PASs is well represented by the figure below:
The diagram illustrates the work steps from 0 (Strategy) to 6 (Handover and Close-out) associated with the PAS 1192-2 and the multiple not scheduled activities (n), that occur during longer times and associated to work phase 7 (Operation and End of Life).
The PAS 1192-3 specifically manage the building’s life-cycle and specify an information management process to support building information modelling (BIM) in the capital/delivery phase of projects. They both aim to support an organization (a construction company, a public body, etc.) carrying out activities during this phase, while developing a specific Asset Digital Information Model endorsing the decision-making process.
Any manager involved in the cycle of activities will have a system of information organization that is commonly defined as a model.
The possibility to digitally “rethinking” a model during the entire BIM process opens scenarios of greater efficiency regarding a better quality, as delivered in terms of conveyed information and, therefore, it represents a better support to the operational decisions that the organization will adopt.
The advantages can be summed up as following:
- Better savings during the entire building life-cycle thanks to decisions based on integrated and updated source of information.
- Reduction of costs due to the automated transfer of information from the building structure to the work operations.
- Less manual data entry.
- Less problems in terms of costs when working on a new or restructured asset due to lack of detailed information about the asset.
- Cost reduction during beginning of operations phase due to construction flaws.
What clearly emerges is that benefits and improvements, which can be obtained by adopting a digital model, are very specific to each different organization. However, each organization should in any case identify what type of information is firstly needed in relation to the decision-making process.
PAS 1192-3 defines such information as Organisational information requirements (OIR).
The figure below gives an overview about how the organization can address the development of its information objectives and how the information is related to the Asset Information Model (AIM) in PAS 1192-3 and to the Project Information Model (PIM) in PAS 1192-2.
