What is the HARI (Hazard and Risk Identification) tool?

HARI (Hazard and Risk Identification)

NEW FOR 2022, every Designer involved in a Project on Mosaic will be able to complete the HARI process, but the HARI will only need to be completed once per Company with design responsibility. So as long as the HARI is completed between the members of a team, it will be considered complete for that company.

The HARI is comprehensive but not exhaustive, and not every HARI element will be applicable to each designer, however, each category will need to be responded to - even if just to mark it as not relevant or to say "I don't know".

Every aspect of a construction project is considered as containing the potential for risk, and is organised as such in the HARI. In the site & surroundings, local ecology, previously existing buildings, or environmental issues such as local schools or elderly care facilities, how the building was designed and the materials which are required to be used during construction.

Subject to the output of each category in the wizard, users may be required to provide further narratives or document uploads where directed. If the required documentation is not available at the time this can be added at a later date via the Documents tab or the PCI or H&S menus.

When each HARI category is completed it will have a status of one of the following;-

  • Green – Hazard eliminated = this represents a hazard that has been considered but is not significant, has been designed out or, after a review, is no longer present. Risk mitigation or control may be achieved through a safe system of work or simply the provision of more information for those at risk.
  • Amber – Design Change/Transferred = Transferred risks have not had any design mitigation applied, they are for another party to eliminate through the HARI. Further mitigation may be possible through additional input by one or more project participants. A HARI may also be Amber following a Design Change, this HARI must be revisited after the design change has been agreed to determine the ultimate status of the Risk.
  • Grey with Amber - User does not know = the user has said "I don't know" in response to the HARI questions, so they are deferring to the expertise of another user. Risks in this status will not appear on the Risk Register, but will appear in the Generated Report. Where no user has answered the HARI satisfactorily, the PD should discuss with the team to work out the best course of action.
  • Grey with Red – Residual Risk (reduced to "manageable") = these risks have had some form of mitigation whether through design, provision of more information, or a recommended safe system of work. Further reduction may be possible through additional mitigation by one or more project participants.
  • Red with Dark Red – Residual Risk (not reduced) – this has been considered during the HARI process, however, possibly even with additional information provided, the same high level of risk remains. 
  • Red – Live Risk = in the absence of any Design Risk Management this risk is assumed to be present and significant. Only through completing the HARI can this risk be considered and reduced.

The role of a project participant with design responsibility is to engage and collaborate with the rest of the team to identify and mitigate risks wherever possible. The HARI wizard facilitates this collaboration.

All Risks which are not Eliminated will appear on the Risk Register. The Designer identifying the risk, their narrative comments and a link to any documentation they attached during the HARI will be accessible via the Risk Register. The Risk Register can be printed or shared as a PDF directly from Mosaic, it is also included within the Generated Report.

By completing the HARI designers can demonstrate compliance with Regulation 9 of the Construction (Design & Management) regulations 2015.
