Introduction Underground infrastructure supervision under the Land Transport Authority (LTA) and PUB (Public Utilities Board) is a high-stakes engineering control regime, not routine site oversight. In Singapore, infrastructure underground works under LTA and PUB supervision require specialized engineering oversight, stringent qualifications, intensive inspection, disciplined documentation, and clear liability allocation to manage high-risk works such as […]

Introduction Any addition and alteration (A&A) or renovation project in Singapore that affects structural integrity, involves temporary works, modifies fire safety systems, or needs building plan approval will require a Qualified Person (QP). Under the Building Control Act, commercial and residential owners cannot proceed with works affecting structural elements, load-bearing walls, fire protection systems, or […]
Introduction Qualified Person (QP) sign-off for scaffolding and formwork is a legal requirement under Singapore’s Workplace Safety and Health (WSH) Act. Every construction project involving temporary works, from concrete formwork falsework to multi-storey scaffold systems, requires independent engineering verification before workers can access the structure or apply load. Skipping this step has measurable consequences: a […]
Introduction QP(S) oversight is the regulatory mechanism that prevents deep excavation failures, protects adjacent structures, and keeps construction projects within legal tolerances across Singapore’s dense urban landscape. When a 30-meter excavation collapsed at Nicoll Highway in 2004, causing the adjacent highway to subside up to 13 meters, the investigation revealed failures in design detailing, analysis, […]
Introduction Obtaining a Building and Construction Authority (BCA) permit is necessary before commencing structural works in Singapore. This permit – formally known as the Permit to Carry Out Structural Works, or ST Permit – is a distinct regulatory step that follows structural plan approval and must be secured before any physical construction begins on site. […]
Introduction Periodic structural inspection (PSI) and construction supervision are two distinct but complementary safety systems that protect Singapore’s built environment across its entire lifecycle. While they share the common goal of ensuring structural integrity, they operate at fundamentally different stages, involve different professionals, and address different categories of risk. Understanding how each system works – […]
Introduction Resident Engineers (REs) and Resident Technical Officers (RTOs) are the mandatory site supervisors who control concrete quality on Singapore construction projects. Their roles, defined under the Building Control Act (Cap. 29, 1989), cover everything from witnessing fresh concrete sampling to evaluating cube compression results and inspecting reinforcement before a pour proceeds. This article covers […]
Introduction Every structural work in Singapore legally requires the appointment of a Qualified Person (QP) before any construction activity begins. The Building Control Act mandates this requirement without exception – whether you are modifying a load-bearing wall in a landed home, constructing a commercial building, or undertaking underground building works. Failure to appoint a QP […]
Introduction In Singapore, the Building Control Act draws a clear regulatory line between QP(Design) and QP(Supervision), and that distinction is the reason one engineer might not be enough. QP(Design) prepares and submits structural plans for approval, while QP(Supervision) oversees construction on site to confirm the works match those approved plans; these are separate statutory roles […]
Introduction Every construction project in Singapore operates under a legally mandated three-tier supervision framework that places a Qualified Person (Supervision), Resident Engineer, and Resident Technical Officer at the center of structural safety and regulatory compliance. Understanding how QP supervision in Singapore works-and how RE and RTO requirements under BCA intersect-is essential for anyone involved in […]
