If you are familiar, you should know how the PE system is abused. 65 yeard PEs are used to endorse highly contentious projects, which I know I few. They sign off knowing they are so old sure no caning or lighter sentence. Early PE standards are very low. Also to sign a piece of rubber stamp paper can cost 800SGD just to certify obvious things that need not get certified like put a 50kg safe on steel plate in the office. The high fines are just loud air noise. Do you think the Nicoll Highway crash was not known before the incident? Do you think the MRT problems were unknown till today? All necessary voices were raised but our high and mighty LTA bo huey. You can bury paperwork, you cannot bury engineering science.
