Safety in Design

Your DOOR projects

Each project carries its own setup, critical risks, phase records and DOOR Register. Open a project to pick up where it was left, or set up a new one.

Project setup

Set the project up before you start DOOR

Three short steps. Who is involved, whether DOOR applies at all, and the critical risks that need to stay front of mind right through the process.

Project details

Names entered as key participants become selectable as phase leads and contributors later on.

Name and role. These appear in the phase lead and contributor pickers.

Do we need to follow the DOOR process?

Make this an explicit decision now rather than an assumption. The answer is recorded against the project.

Does the work involve any of these?

    Critical DOOR risks

    The handful of overarching risks or issues that need to stay front of mind for the whole project. These are not the detailed entries that will populate the DOOR Register. They stay visible across every phase and their status can be updated as the design develops.

    What DOOR is

    A mandatory process for the safe design of every Mirvac structure

    As a developer, designer, project design manager, builder, asset manager and owner, Mirvac is in a unique position to influence the health and wellbeing of the places we create. Design Out Our Risks is how Mirvac entities discharge their duties under Work Health & Safety legislation for the safe design of structures.

    It applies to every project, retail, office, industrial, residential apartments and houses, build-to-rent, masterplan communities and land subdivision. DOOR runs across the project lifecycle. The greatest opportunity to eliminate or minimise risk is during design, with later phases used to verify outcomes, resolve or transfer remaining risks, and capture lessons from the completed asset.

    Read these guidelines in conjunction with Mirvac HSE Element 3, Safety in Design, Guidelines to undertake Design Out Our Risks (DOOR) Reviews.

    The DOOR Framework

    DOOR runs as a single progression across four phases and ten stages, from setting the project up before design begins through to reviewing the completed asset in use. Click any stage to open it, or use Start to begin at the beginning.

    How the framework is built

    The DOOR framework runs across four phases, from setting a project up before design begins through to reviewing the completed asset in use. Each phase covers a distinct part of the lifecycle, and together they make Safety in Design continuous rather than a single event at one milestone.

    Every phase is made up of stages. These break a phase into the actual pieces of work, giving clarity around who is responsible, when it happens, and what the phase has to produce before the next one starts. Formal Safety in Design reviews and workshops occur where required through the later phases, while Plan establishes the context, management approach, DOOR Plan and DOOR Register.

    Stages act as checkpoints, and their order matters. In Plan, understanding the design context and DOOR management approach comes before setting up the DOOR Plan and DOOR Register. In Develop, preliminary design, interrogation, design update and design/product change form an iterative process until risks are eliminated or minimised so far as reasonably practicable.

    In Validate, verification comes before transfer, so nothing is handed over that has not been checked against the built work. In Review and learn, findings are gathered before they are recorded, so lessons reach the next project instead of sitting in a closed register.

    Review and learn

    See how the completed asset performs and feed the lessons forward.

    Purpose

    Review the completed outcome from a post-completion perspective (typically 8-12 months after completion), gather observations, feedback and other relevant inputs, and turn them into recorded findings and actions. The review includes physical inspection of accessible areas of the completed asset and should record any limitations to the inspection. Close or assign remaining items, capture risks, defects, deviations and opportunities, and make lessons available so future projects and design guidance can benefit.

    Subphases, inputs and tools

    Information you need Mirvac tool or template

    Each subphase draws on its own set of inputs. Tools and templates are marked so you can tell what you have to gather from what Mirvac already gives you.

    Risk trajectory

    How the risk picture changes across the phases

    Calculated live from this project's DOOR Register. Only the phases reached so far are plotted — nothing ahead is shown yet. Risk exposure is the total of the current risk scores; controls is the average control maturity. The two lines show direction over time and do not share a numeric unit, and the exposure total is not itself a Mirvac risk band.

    What did we discover during this phase?

    Post-completion experience has been converted into actions and reusable learning.

    The completed asset has been physically inspected where accessible and reviewed using previous DOOR items, PCR items, customer/user feedback, defects, maintenance and operational information, incident data and post-occupancy evidence.

    Remaining matters are either closed or assigned, while risks, defects, deviations and opportunities are recorded so they are not lost after project completion.

    The resulting lessons and recommendations can now inform future projects, design guidance and decisions rather than remaining isolated within the completed project.
