Tasks this bears on
Signing the plans as the qualified person
Being the named person who certifies that they prepared the plans, and who answers for them if the structure fails.
Still human-led✓ Evidence-backed
Checking someone else's structural design
Acting as the independent checker who certifies that another engineer's plans show no inadequacy in the key structural elements.

Where this applies
Section 5 of the Act as published on Singapore Statutes Online, read in the current version. An application for approval of building plans must name the appropriate qualified person appointed to prepare them (5(2)(b)(i)) and, from 1 July 2026, include a certificate signed by that person certifying that he or she prepared those plans (5(2)(e)). For major building works it must also carry an accredited checker's certificate that the plans checked do not show any inadequacy in the key structural elements (5(2)(d)). Section 5(5) lets the Commissioner of Building Control approve plans without checking the plans and design calculations, on the basis of the accredited checker's certificate for major works or the qualified person's certificate in other cases, and 5(6) keeps the right to random checks. It establishes who the law makes answerable for a structural design in Singapore; it says nothing about how the design or the check is produced, whether with software or not, and it counts no one.
What this means
Singapore's building law makes a named qualified person certify the plans they prepared, and for major works lets the regulator approve on an accredited checker's certificate instead of checking the calculations itself.
What it does not yet show
It places responsibility on people; it does not say how the design or the check is produced, how many engineers a project needs, or how other countries assign the same duty.
What you can check
Find the provision in your own building law that says who must prepare, certify and check structural plans, and read whether it names a person or a process.
Does it change the assessment?
No. The impact index is never moved by a single event. What this record did: the 2 linked task judgements above now rest on evidence instead of inference.
