The Cost of ERSS Submissions in Singapore: Breakdown of Consultant Fees, Checking Fees, and Testing
Key Takeaways ERSS costs depend on the excavation, ground conditions, design responsibility, checking requirements, and the level of construction-stage support needed. A useful budget separates professional fees from testing, monitoring, authority coordination, and risk allowances. ERSS is a temporary earth-retaining system used to support excavations and control ground movement. Consultant fees rise with excavation depth, […]
Eurocode 7 Application: Sizing Permanent ERSS using SS EN 1997-1 Singapore National Annex
Key Takeaways Permanent ERSS design in Singapore requires more than selecting a wall section. It depends on a clear design basis, reliable ground and groundwater information, correct Eurocode 7 design approaches, and coordinated construction-stage controls. Define the retaining system, design life, design situations, and movement criteria before sizing members. Build characteristic soil and groundwater parameters […]
Eurocode 7 Application: Sizing Permanent ERSS using SS EN 1997-1 Singapore National Annex
Key Takeaways Permanent ERSS design in Singapore requires more than selecting a wall section. It depends on a clear design basis, reliable ground and groundwater information, correct Eurocode 7 design approaches, and coordinated construction-stage controls. Define the retaining system, design life, design situations, and movement criteria before sizing members. Build characteristic soil and groundwater parameters […]
Encroachment & Boundary Constraints: Permanent Tie-Back Anchors vs. Strutting Systems
Key Takeaways Deep excavations beside property boundaries require the retaining system, construction sequence, approvals, and monitoring plan to be considered together. Permanent tie-back anchors can preserve internal working space but may require rights beyond the site boundary. Strutting keeps support within the site, reducing dependence on neighboring land and easement approvals. Soil, groundwater, excavation depth, […]
Eurocode 7 (SS EN 1997) for Singapore ERSS: Ultimate Limit State (ULS) vs. Serviceability Limit State (SLS)
Key Takeaways Eurocode 7 provides the limit-state framework for Singapore ERSS, but a compliant design also depends on local ground conditions, construction stages, and movement control. ULS checks resistance against collapse, instability, hydraulic failure, and structural failure. SLS checks movements, settlement, deformation, and effects on neighbouring assets. Groundwater and soil variability must be reflected in […]
Designing ERSS for Kallang Formation: Navigating Marine Clay in Singapore Basements
Key Takeaways Deep excavation in Kallang Formation demands a ground model that accounts for soft marine clay, variable fill, groundwater, and time-dependent movement. ERSS design is strongest when geotechnical and structural decisions remain coordinated from investigation through construction. Build the geological and groundwater model before selecting the ERSS. Treat excavation staging, support installation, and monitoring […]
Temporary King Post and Strutting Systems: Structural Detailing for BCA Approval
Key Takeaways A temporary king post and strutting system is only as reliable as its design basis, connections, construction sequence, and site control. BCA approval depends on a coordinated package that explains both the engineering and how the system will be built. Define the ground, loading, geometry, and construction stages before detailing steel. Check member […]
Roof extension regulations in Singapore: Structural limits you must know
Key Takeaways Adhering to Singapore’s strict building codes is essential for any roof extension project, requiring careful planning and professional oversight to remain compliant. BCA approval remains the primary requirement for all structural additions. Proper calculation of dead and live loads ensures long-term safety. Professional Engineers must endorse all structural analysis documentation and plans. Climate […]
Essential structural guidelines for building a swimming pool in your landed home
Key Takeaways Designing a swimming pool for a landed property involves navigating a complex landscape of regulatory, geotechnical, and engineering requirements to ensure long-term stability and safety. Adhere to site-specific setbacks and zoning rules mandated by planning authorities. Prioritize professional soil investigations to determine appropriate foundation design. Model structural integrity through advanced analysis before starting […]
Rebuilding vs. A&A: A structural engineer’s perspective on Singapore homes
Key Takeaways Deciding between renovation and complete reconstruction requires a deep understanding of your property’s current state and your long-term spatial goals. Homeowners must balance regulatory constraints with engineering realities to create safe, valuable assets for the future. Categorize projects based on structural impact to avoid unnecessary regulatory delays. Understand the specific site constraints, such […]
