Typical Submission Package at a Single Gateway
3D Coordinated BIM Models for Joint Submissions
The joint submission may consist of 3D coordinated BIM models. This means that all 3D BIM models from different disciplines must be properly coordinated. QPs are responsible for ensuring this coordination while maintaining compliance with all applicable Acts and Regulations.
For submissions containing both 3D BIM models and 2D plans,
- QPs must explicitly state in their cover letter if any of the 2D plans are for approval. Without such indication, the 3D BIM models will take precedence, and the 2D plans will serve only as supplementary reference
- For 2D plans to be considered for approval, they must comply with agency’s requirements in CORENET X Code of Practice
- In cases where 2D plans and 3D models are submitted for approval, QPs must ensure that information in the 3D models and 2D plans tally and do not conflict
In addition, only the 3D BIM models(s) and 2D plan(s) for approval by the appointed QP(s) for the relevant section(s) should carry their digital signature.
The table below shows a sample of what is inside a typical CORENET X submission package for Construction Gateway.
The purpose of this illustration is to highlight that not everything in CORENET X will have to be modelled in 3D. For practical reasons, it may not make sense to expect complex details to be modelled, and hence the submission package will also consist of other supporting documents such as 2D detailed drawings, design calculation reports etc.

We have highlighted in the yellow boxes examples of what may be required. Note that this differs across project types and is not exhaustive.
