In short: Every building project in Singapore that touches structural elements requires one or more BCA submissions — the regulatory approvals issued by the Building and Construction Authority. The most common types are A&A (Addition & Alteration), new erection, regularisation, ERSS, temporary structures, and Periodic Structural Inspection. Each submission requires a registered Professional Engineer's endorsement. From 1 October 2026, all new building projects regardless of s

In short: ERSS (Earth Retaining and Stabilising Structures) is the BCA submission category for any temporary or permanent structure designed to retain earth, support excavations, or stabilise ground. It includes sheet piles, contiguous bored piles, secant piles, soldier piles, diaphragm walls, ground anchors, and soil nailing. ERSS submissions in Singapore must be endorsed by a registered Professional Engineer (Geotechnical), with movement criteria, monitoring plans, and — fo

In short: Regularisation is the formal process of getting BCA approval retroactively for a building structure that was constructed, modified, or extended without prior approval. In Singapore, owners discover unauthorised structures most often when they try to sell, refinance, renovate, or face an enforcement notice. Regularisation typically takes 4 to 12 weeks and ranges from S$2,500 to S$20,000+, depending on complexity. Unaddressed unauthorised structures can result in BCA

In short: CORENET-X is the Building and Construction Authority of Singapore's new digital regulatory submission platform, replacing the legacy CORENET system. It requires BIM-based, model-driven submissions federated across architectural, structural, and MEP disciplines. Since 1 October 2025, CORENET-X is mandatory for all new projects with gross floor area (GFA) of 30,000 m² or more. From 1 October 2026, the mandate extends to all new building projects regardless of size. Pr

In short: A PE endorsement is the formal sign-off by a Singapore-registered Professional Engineer that a structural, geotechnical, or civil design meets all applicable codes and regulations. It is legally required for most BCA, SCDF, PUB, LTA, HDB, and ECM submissions involving structural elements. The PE who signs takes personal civil and criminal liability for the design's safety. Fees range from S$300 for simple temporary structures to tens of thousands for large structura
