Can the same PE design and supervise my works?
Yes. The Building Control Act requires an appropriate QP to prepare the plans and another appointment for supervision, but the same individual can hold both roles on many projects. For the structural elements of major building works, however, the supervising QP must not be a partner, officer or employee of the developer, the builder, or an associate of either. Ask your QP to confirm in writing which roles they hold.

The fuller picture
A PE endorsement is a statutory signature: only a Professional Engineer registered with the PEB and holding a practising certificate in force may sign plans or certificates that the law requires a PE to sign, and documents signed otherwise are invalid. The endorsing PE owes duties to the client, the regulator and the public, which is why owners are better served appointing and paying the engineer directly.
