Protecting Adjacent Sensitive Structures: Dilapidation Surveys and Building Impact Assessments (BIA)
Key Takeaways Adjacent structures can be affected by excavation, vibration, groundwater changes, temporary works, and construction loading. A carefully planned survey and building impact assessment creates a factual baseline for protection, monitoring, and fair resolution of disputes. Record existing conditions before construction begins. Assess both the building and the proposed construction effects. Give vulnerable structures […]
Setting Alert, Action, and Limit (AAL) Levels for ERSS in Urban Singapore
Key Takeaways A defensible ERSS AAL framework turns monitoring data into timely, proportionate decisions. It must be grounded in the design, the site baseline, Singapore’s regulatory setting, and clear responsibilities. Establish movement objectives before selecting trigger values. Build the baseline risk profile before excavation begins. Match instruments and thresholds to each receptor and construction stage. […]
Common Reasons BCA Rejects Temporary ERSS Submissions (And How to Avoid Them)
Key Takeaways Temporary ERSS submissions are commonly returned when the technical evidence, drawings, design assumptions, and authority responses do not form one clear and verifiable package. Confirm that every required form, report, calculation, drawing, and supporting record is included. Base the ERSS design on current site investigation, groundwater, utility, and neighbouring-structure information. Show the design […]
The Annex C & Annex E Workflow: On-Site ERSS Compliance During Execution
Key Takeaways ERSS compliance during execution depends on disciplined supervision, clear authority, and records that connect site actions to approved design and monitoring requirements. Annex C controls the construction and inspection workflow for ERSS works. Annex E provides the monitoring, threshold, and response framework. The RE, RTO, and Site Manager need distinct but coordinated responsibilities. […]
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, […]
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 […]
Periodic Facade Inspection (PFI) Singapore: A compliance guide for aging buildings
Key Takeaways Staying ahead of regulatory maintenance is vital for property owners managing aging building stock. This overview summarizes critical steps, roles, and technical considerations involved in maintaining safe, compliant structures in Singapore. Mandatory PFI applies to buildings over 13 years old, requiring inspection every 7 years. Qualified Persons (QP) are legally responsible for conducting […]
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 […]
