PAS1192-6 provides guidance on how Health & Safety information is generated and flows throughout the project and asset lifecycle progressively from the outset in order to:
Provide a safer and healthier environment for end-users;
Mitigate the inherent hazards and risks across the whole project lifecycle;
Result in improved construction safety performance, less incidents and associated impacts;
Provide for clearer and more assured and relevant health and safety information to the right people at the right time;
Reduce construction and operational costs.
Key points in the document
Applying PAS1192-6
This document should be applied to the project via the EIR and accepted and be specified in the Project BEP by the design teams. In doing so, five phases are applied to the project stages (Table 1) and a progressive development of the H&S are developed at each phase (Figure 2) using the collaborative process in the CDE:
Risk Information Framework
To ensure the process and development of the H&S as intended (Section 1 above). The participants are required to implement four components in to the H&S development for each phase (Figure 3)
1.1 Identify – Significant hazards e.g. risk registers
1.2 Manage – The identified hazards e.g. risk matrix
1.3 Share – The information documented about the risks and the management of such at each handover
1.4 Generalise – Document the learning outcome from point a – c to be used for educational purposes and sharing as an open information source.
Participant implementation strategy
This strategy is the documented plan for the Risk Information Framework. The Client should provide the framework for this process at the beginning of the project and each participant is required to provide a strategy to deliver the required information at the relevant phase.
Implementation of the information requirements
The information that has been collated during each phase should be shared in a specific format:
a) Document table or spreadsheet
b) COBie – recorded in the Issues sheet (tab) in the COBie document. As per PAS1192-6 Section 9 Table 3.
c) Modelling and Planning applications
that is consistent and reusable and that clearly indicates the context and the significant risks that have been identified (Figure 4).
Context being the establishment of a benchmark for what is considered “significant risk” based on the reasonable expected skills and competences of the team members for the phase. Once the benchmark has been established, the context information is developed alongside the Risk Register.
H&S & BIM
The following clauses cover BIM-specific considerations:
4.3 Information Management: The H&S process can and should be implemented on all project regardless of BIM. However, 4.3 covers many of the BIM-centric processes.
4.3.2. Use of CDE: The project H&S information should be subject to the CDE process along with other project information. Throughout all project stages, information should be shared with other participants. Formal H&S deliverables should be published and superseded H&S information should be archived.
4.3.3. Use of entities and annotations in models and documents: As part of developing project information, the H&S risks should be associated with the relevant elements within the 3D model. This needs to be reported in the Issues sheet in COBie.
4.3.4. Use of attributes: The necessary attributes should be included in the objects and defined in the EIR as the LOI requirements for each project stage (refer to clause 6.2.10). More detail is also provided in clause 10.3 which explains the use of an H&S-specific IfcPropertySet named “HSE_Risk_UK”. All required H&S information inform of attributes to models or documents should be in this property set group. This includes, for example:
- RiskName
- RiskType
- AssociatedProduct
- AssociatedActivity
- AssociatedLocation
- UnmitigatedConsequence
- MitigationProposed
- etc
Clause 10 provides further information regarding the representation of H&S risks in BIM. It defines the HSE_Risk_UK property set & refers to Annex A for the required properties.
Conclusion
In short, PA1192-6 emphases that H&S must be addressed in a structured and consistent way from the outset of a project as prescribed by the client. Following this, the collaboration process that we are now getting used to on any BIM Level 2 project requires each stakeholder to review, agree and implement the standards and processes to be used and ensure they are followed and monitored throughout the project stages. These additional considerations are divided up in to phases and what need to be done is listed out quite clearly.
The document does not refer to the new CDM2015 changes but there are some points raised in PAS1192-6 that are directly addressing some CDM2015 changes e.g. competence assessment that is required to provide the Risk Register, ensuring risks are eliminated and controlled and passing of information. The PAS document does raise these points highlight that actors are participants fulfilling a specific role throughout the duration of the project. It seems that the CDM2015 and the PAS1192-6 should be better coordinated and cross-referenced, and the project team should act as if one set of information was agreed.
Regardless, teams will need to take in and consider both documents in the planning of their projects.
