To facilitate the transition, we had introduced a <strong>temporary 6-months extension to Additional Buyer’s Stamp Duty (ABSD) remission and Project Completion Period (PCP) timelines</strong>. The ABSD and PCP are 2 separate regimes. As such, requests for ABSD remission and PCP extensions are assessed independently. <br> <br> The ABSD remission timeline will be extended by 6-months for the commencement and completion of residential development, and sale of housing units in residential development projects in relation to the remission of the ABSD for qualifying licensed housing developers. To qualify for the ABSD remission extension, projects must meet the following criteria: <ol> <li>Projects must entirely undergo the CORENET X approval process for building works (i.e. submit and secure clearance for Design and Construction Gateways) to qualify for the extension;</li> <li>The first submission must be made during the transition period from 18 Dec 2023 to 31 Dec 2025; and</li> <li>Projects must have a minimum of 6 months left of its 2-year ABSD remission timeline for the commencement of development, at the point when the first submission is made under the CORENET X approval process for building works.

Under CORENET X, LTA, NParks and PUB currently require the proposed building works of the projects (including its external works) to be submitted as a single submission. The intent of this is so that the proposed external works are coordinated with the main building works prior to submission and agencies could review them holistically. To guide the industry on the details required for external works, the agencies have worked together to align their regulatory objectives and requirements. Due care was taken to ensure that: <ol> <li>There are no direct conflicts in the rules between the agencies.</li> <li>Various components of the road typology is holistically reviewed by the respective agencies within the same gateway.</li> </ol> Nonetheless, many industry practitioners have also raised concerns over potential project delay due to external works clearance. Hence LTA, PUB and NParks have conducted a review into this process. In cases where the external works may take longer than expected and hence affecting the overall project, agencies are agreed that full requirements for external works need not be cleared in CG. Instead, LTA, PUB and NParks have come together to agree that <strong>only the key interfacing details between the main development and external works need to be firmed up and cleared during CG.</strong><br> <br> <strong>The details of the external works may then be subsequently submitted to the relevant agencies as independent submission following the CG clearance.</strong> This delinking of the external works process from the main development process is meant to help mitigate the potential delays projected by many industry practitioners. <br> <br> <a href="/images/default-source/corenet-x/delink-external-works.png?sfvrsn=1f225041_1"><img alt="" src="/images/default-source/corenet-x/delink-external-works.png?sfvrsn=1f225041_1" data-displaymode="Original" title="Delink External Works" data-openoriginalimageonclick="true"></a><br> For more information on the External Works, please refer to page 158 of the <a href="https://go.gov.sg/cxcop">CORENET X Code of Practice.</a> <br> <br> </div> </div><div class='sfContentBlock'><div class="accordion"><strong><span style="color: rgba(0, 0, 0, 1)">Review on the ST Submission Process for Huge Projects </span></strong></div> <div class="panel"> <br> Under the new Regulatory Approval for Building Works (RABW) framework, project teams are required to collaborate upfront and submit a set of coordinated BIM models across various disciplines.

It is challenging to complete and submit detailed structural design of the whole project in one attempt, especially for large projects that require Accredited Checker or Accredited Checking Organisation’s endorsement. <br> <br> To address industry’s concern, detailed structural design and calculations for eligible projects are allowed to be submitted in a limited number of part ST submissions. <br> Eligible project that qualify for Part ST Submissions are defined as: <br> <br> <ol> <li> <strong>Building Projects:</strong> Any project with a <strong>Gross Floor Area (GFA) > 40,000sqm</strong> is eligible for part ST submission if – <ol style="list-style-type: lower-alpha"> <li>The project consists of 5 or more blocks of building of at least 4 storeys high each; or</li> <li>The project consists of 3 or more blocks of building of at least 4 storeys high each, with common podium or basement.</li> </ol> </li> <li> <strong>Infrastructure Projects:</strong> <ol style="list-style-type: lower-alpha"> <li>Infrastructure works that function like a building with length > 150m (e.g. MRT stations, transport nodes/ interchanges);</li> <li>Infrastructure works that are mostly engineering works with length > 400m (e.g. railway tunnels, viaducts, large scale drains and sewers)</li> </ol> </li> </ol> For projects that are unable to meet the above criteria and would still wish to submit as part ST submissions, please pre-consult with agencies early.<br> <br> During submissions at the Construction Gateway, the coordinated BIM model capturing the overall design of the project must be submitted in full, including architectural, M&E and structural BIM models, as well as supplementary documents as per required in the Code of Practice. <br> <br> For eligible projects that qualify for Part ST Submissions, full coordinated structural BIM carcass model must be submitted in the 1st CG submission. Detailed structural submissions (ST), including detailed calculations, AC/ACO reports, etc, may be submitted in parts.
