Following on from our recent article and the first in the ‘Building a Safer Future’ series, we once again speak with BIM Manager Varun Soni to establish how the three key gateways will be introduced to ensure that a ‘Golden Thread’ of information is maintained throughout and to enable a thorough accountability trail.
To ensure that the new proposals are adhered to, three key gateways will be introduced during the project. Gateway 1 will be at planning approval, Gateway 2 at the start of construction, and finally Gateway 3 will be at handover. This will require more thought and planning of safety risks at the first Gateway and the Building Safety Regulator to sign off Gateway 2 and 3 before the next RIBA Stage can commence. Even once these gateways are passed, there will be continuous audits of this information taking place, for the occupation of residents in the building.
The details of a building’s design and construction, including any changes, must be digitally recorded and passed along the chain of responsibility. This information also needs to contain detailed records of how occupants/residents are trained to understand fire routes, shown up to date fire evacuations and updated on information. All of this information is brought into the ‘Golden Thread’ and needs to be accessible by all relevant parties to create a single source of truth.
The Golden Thread should detail how a building was designed, built and maintained, with all project and asset data being held digitally. It should act as a live hub, linking all data about how a building is managed and operated. This record will capture the digital engagement of people, thus giving a clear accountability trail to avoid risk and ultimately to save lives. This is known as the ‘single source of truth’.
At the handover stage between Gateway 3 and occupation, key information (the Golden Thread) will have to be handed over from the contractor to the Accountable Persons, as well as the Building Safety Manager and the Client. All parties will need to confirm the handover of information, and it will need to be signed off by the Building Safety Regulator and a license issued before the asset can be occupied. The Accountable Persons will continue to be responsible for the Golden Thread and will need to ensure that the information remains accurate and up to date. This doesn’t just include the asset information but also information such as customer integration. At Gateway 1, the planners will be accountable as this stage is all about ensuring that reasonable steps have been taken to plan any risks out of the design. The Building Safety Regulator will be accountable at Gateway 2 and Gateway 3, as well as for any ongoing audits.
This information handover process is expected to be in line with the UK BIM Framework and information delivery cycle as well as the responsibilities of those who work on a project. As outlined within ISO 19650, functions that support both the asset and project information management responsibilities must be clearly outlined from the start.
Having a clear understanding of the key roles and responsibilities on a project will ultimately enable us to maintain a strong audit and accountability trail, this is a crucial component to the development of the information on a building or infrastructure asset. The information and models created across the project are critical to the Golden Thread – a series of digital information and data rich models that all people involved in the project can work on, from the Architect to the Client and into the asset management of a building. It is the digital description of every aspect of the built asset that allows the information to be useful during its operational phase so that it can be checked for compliance and, ultimately, safety. The models draw on information assembled collaboratively and updated at key stages of the project. The key to all gateways and the Golden Thread being maintained is keeping a track of the information of an asset and how it evolves through its lifecycle.
