CORENET X will be rolled out progressively and eventually replace the current CORENET system when CORENET X is implemented (target in end 2023). In the steady state, CORENET X will handle both BIM and non-BIM submission. We will ensure that the transition is smooth, taking into consideration the user experience to QPs to avoid confusion.

All projects are required to be submitted to CORENET X for regulatory approval. The regulatory approval process, which consists of the 3 gateways, will apply to both BIM and non-BIM submission.

For smaller projects, we are looking into simplifying the process so that they need not go through every gateway. This includes the possibility of lodgement schemes for less complex projects (like landed residential properties).

For BIM e-submission requirements, they will apply to projects above 5,000 sqm. These projects include:

• New building and infrastructure projects; and

• A&A projects involving reconstruction or addition of any new building or infrastructure.

We are also reviewing whether the requirements for BIM e-submission should be extended to other projects less than or equal to 5,000 sqm that do not require BIM e-submission today. More details on the projects that will submit to CORENET X will be released later.

Upon CORENET X launch targeted end of this year, only new projects that have not started submission will submit to CORENET X. Ongoing projects that started submissions before CORENET X launch, e.g. halfway through DC or BP clearances, will continue to submit through CORENET 2.0.

Progressively and gradually after launch, we will transit 2D and 3D submissions of projects by stages from CORENET 2.0 until all projects at all status of clearances will be on CORENET X only. We will inform industry of more details prior to the launch and subsequent stages to ensure projects have enough time to prepare for their respective transition.

In line with the service standards across agencies today, we will strive to give a consolidated multi-agency response within 20 working days for each gateway submission.

In terms of overall approval process duration, we anticipate more time will be needed upfront during the initial planning and design stages, both for QPs to incorporate and coordinate multi-disciplinary inputs, to meet each gateway's level of details required in the consolidated BIM model, and for agencies to collaborate and provide consolidated responses.

However, we anticipate that increased efforts to get the design right upfront will lead to reductions in the possibility of conflicts between responses by agencies, reducing QPs’ resources in resolving these conflicts with relevant agencies much later in the project timeline. This will also lead to less painful downstream design iterations, abortive reworks and demolition of works, especially towards the completion of the project at TOP stage. Overall, this will lead to a much shorter overall approval process duration as compared to that of today.

At each gateway in the new CORENET X regulatory approval process, SCDF will conduct checks on major requirements that may affect cross-agency requirements or piling works. Examples include the provision of fire engine access, exit staircases and fire lifts.
For other technical details that are specific to SCDF only, SCDF may still adopt the self-regulation approach to grant approval first and subject the submission to random audit checks after approval.
SCDF is still assessing this and will update when more details are ready.

Each project team will jointly submit coordinated BIM models from the Architectural, Structural and MEP (Mechanical, Electrical, Plumbing) disciplines, consisting of:

• OpenBIM format files in the Industry Foundation Classes (IFC) format; and

• Related submissions and supporting documentations (format to be confirmed)
