Design changes often occur during the design and construction phases. Depending on the extent of changes, amendment submissions may be required at the appropriate Gateways. Please refer to the following guide for more details on making an amendment plan submission on CORENET X.

Guide to Amendment Plan Submission on CORENET X

• Ensure all project members have set up Singpass for Business (Corppass) settings if they are representatives from an organization, including Corppass access to the CORENET X Submission Portal (https://portal.corenet.gov.sg/)
• The project team should collaborate and agree on roles and responsibilities of respective QPs required each project
• The Project Coordinator should support /  receive support  to/from the project team members and assistants for smooth onboarding of all submissions.
• Within each organization, ensure relevant IT and Finance colleagues are notified of the organization’s roles in the project, to avoid unnecessary delay to the rest of the project team during submission preparations.

• All project team members should plan carefully on the types of submissions the project will undergo, and the timing, party / parties and format(s) involved in each submission
• There are Pre-Submissions (e.g. NParks EMMP, NEA NIA) that are to be submitted by email and not via CORENET X Submission Portal – read the Code of Practice carefully for more info.
• Projects requiring JTC Land Consent can apply via CORENET X.
• Projects are encouraged to carry out pre-consultations for household / storey / transit shelter compliance
• Project team members are encouraged to carry out pre-submission consultations as early as possible, to clarify or enquire on agency requirements, potential deviations.
• Do not forget to indicate your query in the CORENET X pre-consultation submission form. The more details and information you attach in the query, the more agencies can assist and expedite your query. 

• The project team should discuss the timing of demolition works in relation to when the regulatory submissions are expected to be made via CORENET X, whether through the 3-Gateway Process or Direct Submission Process
• If the intention is to carry out demolition works prior to making any regulatory submissions for new developments, the demolition submission will be a joint submission made to both BCA and URA, with the payment of applicable fees. Do note that BCA will approve the demolition submission only where URA similarly approves such demolition, or has authorised/approved the redevelopment of the site
• It is optional to submit in 3D

• If you are unable to find a particular agency’s form for your Design Gateway or Direct Submission Process, review the respective QP’s roles and responsibilities, and initiate Developer’s appointment for missing scopes to open the missing form.
• After you have indicated project information in the form inputs, the Submission Portal will show whether you can submit for Lodgement.
• Utilise the “Fee Computation” feature to double-check that Submission Portal inputs for submission requiring fee payments are correctly filled in
• Fees below $10,000 are encouraged to be paid via credit card
• There is no 72-hour deadline for payment of fees after submission. However, processing will only commence after relevant fee payments have been completed by the project team and verified by relevant agencies.
• Remember to indicate and check the last I/C and minimum platform levels in the Design Gateway IFC+SG models have been indicated and are accurate, double-checking that the levels are the same as indicated in the Submission Portal form
• Where applicable, project teams are encouraged to upload models early to utilize the “Preview Model” feature on the Submission Portal, to ensure models are geo-referenced and coordinated accurately prior to submission.
• It is not necessary to indicate “Magenta”, “Cyan” and “Yellow” colours to reflect “New”, “Existing”, and “Removed” elements in BIM models for A&A or Conservation projects. Instead, relevant IFC+SG parameters (e.g. Status parameter) should be populated for relevant elements accordingly.
• It is possible for larger projects (e.g. MRT Stations) to submit for both Design Gateway and DSP concurrently (e.g. Design Gateway for the Station Box and DSP for the Pedestrian Overhead Bridge)
• It is possible to submit for Demolition after the 1st Design Gateway or DSP Submission. Approval will only be granted after URA Lodgement or approval has been obtained.
• (Does not apply to Direct Submission Process) It is possible to submit for advance comments on structural submissions for Piling Gateway after the 1st Design Gateway Submission. Approval will only be granted after Design Gateway Approval has been obtained.

• Relevant agencies will provide Written Directions or Approvals after a Service Level Agreement of up to a maximum of 20 working days.
• For joint submissions, only agencies with WDs will issue responses – agencies who are ready to issue approval will not respond until the subsequent resubmission where all relevant agencies are agreeable to approve
• Written Directions for BIM submissions will also include a BIM Collaboration Format (BCF) zip files. Free BCF plugins and apps are available to view the BCF files in native BIM software.
• Do not upload outdated documents (including models and plans) into the resubmissions
• Fee top-ups (e.g. after wrong form inputs or change from lodgement to processed submission) can be made during re-submissions. Agencies may also ask for fee top-ups before issuing a decision

• Joint Submission approvals consist of individual approval/clearance letters of relevant agency line departments.
• When a submission is ready for approval, agencies will generate digital checksums for approved documents requiring agency authentication (as a more secure replacement for agency watermarks)
• It is possible to make amendments for all approvals except Design Gateway. Immaterial changes to Design Gateway approved submissions may be submitted in the Construction Gateway. When in doubt, the project team should clarify with the relevant agency / agencies.
• Major changes to the Design Gateway approved submission will require a re-submission to the Design Gateway.
  

• The Piling Gateway is an optional gateway for projects who require piling works to start earlier onsite prior to Construction Gateway submission
• It is possible to submit Piling Gateway and Construction Gateway concurrently.
• Piling Gateway submissions comprise of BCA (ST), and may be a joint submission with LTA (Rail) if applicable
• The project team, including the builder where applicable, should discuss early on how part-ST submissions should be carried out prior to pre-consultation with BCA
• Ensure the Accredited Checker (AC), PE (Geo), AC (Geo) are onboarded, appointed and aware of their roles in the projects, where applicable.
• Resident Engineers (REs) and Resident Technical Officers (RTOs) can be directly added by the C&S Engineer on the Submission Portal.  The Project Coordinator and Developer do not need to get involved in their additions.  

• Independent Submissions are technical submissions to one agency line department without affecting other agencies (e.g. ERSS works, Fire Protection/Mechanical Ventilation Plans)
• Waivers can be applied on the CORENET X Submission Portal.
• Independent Submissions can be submitted in the non-BIM format
• It is important to understand when and which Independent Submissions can be submitted for your project. Pls study the Code of Practice carefully, and clarify with agencies early if in doubt. Wrong assumptions of Independent Submissions and Waivers may lead to delays in the project timeline.

A checksum is an alphanumeric value that uniquely represents the contents of a file. It is akin to the digital fingerprint of the file.

In the approval response, the QP will find a “List of Approved Plans” by each agency. The QR representation of the Approved Plan’s checksum will be listed in the “List of Approved Plans” (1 unique checksum per file).

To verify if a file is the Approved Plan, you can compare the checksum of the file with the checksum listed on the “List of Approved Plans”.
