How long is the validity period of the plumbing builder's certificate of Beijing Construction Committee, and where can I check whether it has expired?
3 years, the certificate has a "validity period", which can be viewed on the certificate.

Before the expiration of the 3-year validity period of the constructor's certificate, you must attend the required hours of continuing education and pass the examination (assessment) before the certificate can continue to be used. The certificate can only be used after completing the required hours and passing the exam. If you don't participate in continuing education, your certificate will be invalid and you must retake the exam.
