In short: Foundation design is the geotechnical and structural engineering of a building's substructure — piles, raft slabs, footings — that transfers all building loads to competent ground. In Singapore, foundation design must be endorsed by a registered Professional Engineer (Geotechnical) under the PE Act and submitted to BCA. Common Singapore foundation types are bored piles, driven piles, micropiles, raft foundations, and shallow footings. Foundation design is one of the

In short: An A&A (Addition & Alteration) submission is the BCA approval required for renovation, extension, or change-of-use works affecting structural elements in Singapore. Required when load-bearing walls, columns, beams, or slabs are altered. Endorsement by a registered PE Civil is mandatory before construction. Typical fees: S$1,500–S$5,000 residential, S$3,000–S$10,000 commercial. Timelines: 1–3 weeks for the PE side, 4–8 weeks for full BCA approval. Most renovations th

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: Periodic Structural Inspection (PSI) is a mandatory inspection regime under Singapore's Building Control Act for older buildings. PSI must be conducted by a registered Professional Engineer (Civil), with the inspection report submitted to BCA. Non-residential buildings are inspected every 5 years. Residential buildings are inspected every 10 years. Buildings become subject to PSI from their 13th year of age. Failing to comply is an offence under the Building Control

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

Er. Cavan Chai Han Hon | PEB Reg. No. 5376 | Civil & Structural | 300+ Projects | BCA · NEA · SCDF · LTA · PUB What is PE Endorsement in Singapore? In Singapore, only a Professional Engineer (PE) registered with the Professional Engineers Board (PEB) can legally endorse structural, geotechnical, and civil engineering drawings for submission to BCA, NEA, SCDF, LTA, and PUB. PE endorsement is mandatory for building works involving structural changes, deep excavation, ear

Geotechnical engineering is one of the most technically demanding disciplines in Singapore's construction sector. As Singapore continues to develop vertically and underground, the need for competent geotechnical PE endorsement has never been greater. Deep excavations for basement carparks, MRT-adjacent works, high-rise foundations, and tunnel construction all require specialist geotechnical PE expertise. CVC Engineers provides PE geotechnical and tunnel endorsement services f

Fire safety compliance is a non-negotiable requirement for all buildings in Singapore. Under the Fire Safety Act (Cap. 109A), building owners and contractors must obtain the necessary fire safety approvals from the Singapore Civil Defence Force (SCDF) before occupying or modifying any building. Failure to comply can result in stop orders, fines, and in serious cases, criminal prosecution. CVC Engineers provides comprehensive SCDF and FSSD fire safety submission services for a

In Singapore's construction industry, temporary structures play a critical role in enabling safe and efficient building works. Yet they carry their own set of regulatory requirements — any temporary structure that poses a risk to public safety must be designed, endorsed by a registered PE, and in many cases submitted to BCA for approval before it can be erected. CVC Engineers provides fast, reliable temporary structure endorsement services for contractors and developers acros

Every construction project in Singapore that involves earthworks — excavation, site clearance, or ground levelling — must have an approved Earth Control Measure (ECM) plan before work can begin. Without a PE-endorsed ECM plan submitted to and approved by the National Environment Agency (NEA), your contractor cannot legally start earthworks on site. CVC Engineers specialises in fast-tracked ECM submissions in Singapore, with a turnaround of as fast as 3 working days. This give
