PLAXIS 2D/3D Best Practices for BCA ERSS Design Reports
Key Takeaways A dependable BCA ERSS report is built on traceable assumptions, realistic staging, and clear interpretation of ground–structure interaction. Establish the design basis, project constraints, and submission responsibilities before modeling. Convert investigation data into a layered ground model with documented uncertainty. Select two-dimensional or three-dimensional analysis according to geometry, loading, and interaction effects. Simulate […]
Navigating the Multi-Agency Web: Coordinating ERSS Approvals with BCA, LTA, PUB, and NParks
Key Takeaways ERSS approvals are easier to manage when technical design, authority interfaces, and construction controls are planned as one coordinated process. Confirm the approval landscape before fixing the design or excavation sequence. Establish one technical basis from investigations, utility records, and ground data. Separate BCA requirements from conditions imposed by LTA, PUB, and NParks. […]
The 1.5m Rule and Beyond: When Does Temporary Groundwork Require a Formal BCA ERSS Submission?
Key Takeaways The 1.5m threshold is a useful starting point, but it should not be treated as a blanket exemption. Temporary retention, ground conditions, neighbouring assets, and construction sequence can all affect whether formal engineering review is needed. Excavation depth is only one part of the ERSS assessment. A QP should confirm the applicable submission […]
CORENET-X Transition Guide: Submitting Temporary ERSS via Singapore’s OpenBIM Engine
Key Takeaways Temporary ERSS submissions require more than a well-designed retaining system. They depend on clear professional accountability, coordinated OpenBIM information, disciplined quality checks, and reliable revision control from design through removal. Confirm the CORENET-X submission scope and transition requirements early. Define responsibilities among Qualified Persons (QPs), C&S Consultants, BIM Managers, and the wider project […]
QP(ST) vs. QP(Geo) vs. AC(Geo): Deciphering Roles and Responsibilities in Singapore ERSS
Key Takeaways ERSS projects depend on clearly separated professional duties and disciplined coordination. The distinctions matter most to Developers, Main Contractors, Foreign Engineering Firms entering Singapore. QP(ST) focuses on structural temporary works and their interfaces. QP(Geo) leads geotechnical assessment, analysis, and design decisions. AC(Geo) independently reviews geotechnical safety and design adequacy. Developers and contractors retain […]

How to Prepare Tender Documents for Building Work

Learn how to prepare tender documents that define scope, manage compliance, compare bids fairly, and reduce construction risk before work begins safely.
Retrofitting Existing Underground Basements: Converting Temporary Systems into Permanent Structural Retainers
Introduction Converting temporary excavation support systems into permanent structural retainers is one of the most cost effective strategies available for retrofitting existing underground basements in Singapore. Rather than demolishing temporary shoring and rebuilding from scratch, this alternative approach preserves the existing structure while upgrading it to meet long-term performance standards-saving significant time, cost, and site […]
Developing the Permanent ERSS Operations Maintenance O&M Manual: Complete Guide for BCA Compliance
Introduction Developing the permanent ERSS operations maintenance O&M manual is a mandatory requirement under Singapore’s Building Control Act for any Earth Retaining and Stabilising Structure that remains as part of the permanent works. This operations and maintenance manual serves as the definitive reference document for long-term structural monitoring, inspection protocols, and load capacity management – […]
As Built Verification Protocols for Permanent ERSS Prior to TOP CSC Approval
Introduction As-built verification protocols for permanent Earth Retaining and Stabilising Structures (ERSS) are mandatory post-construction inspections that must be completed before the Building and Construction Authority (BCA) grants Temporary Occupation Permit (TOP) or Certificate of Statutory Completion (CSC) approval in Singapore. These protocols confirm that every permanent retaining element – from diaphragm walls to ground […]
