Qualified Person (QP) appointment and BCA CORENET building plan submission services in Singapore — managed by Er. David Zheng Zhijian, PE (Civil) PEB No. 4385.
A Qualified Person (QP) in Singapore is a registered architect or Professional Engineer appointed under the Building Control Act (Cap. 29) to take responsibility for the design and supervision of building works, and to make formal building plan submissions to the Building and Construction Authority (BCA) on behalf of the building owner or developer.
For structural works, a PE (Civil) acts as QP (Structural) — responsible for structural drawings, calculations, and compliance with BCA's structural requirements. The QP signs all submissions, responds to authority queries, and certifies the completed works.
A QP is not the same as a PE endorsement. PE endorsement is typically for smaller-scope works (HDB renovations, MCST requirements, temporary structures) that do not require a full BCA building plan submission. QP submission is a more formal, ongoing appointment required for significant building works under the Building Control Act.
QP.sg's QP services are provided by Er. David Zheng Zhijian, PE (Civil), PEB Registration No. 4385 — a registered Professional Engineer authorised to act as QP (Structural) for building plan submissions to BCA Singapore. Verify at peb.gov.sg.
QP appointment is a legal requirement under the Building Control Act for these categories of works.
Not all projects need a QP appointment. HDB flat renovations, condo MCST requirements, and temporary works typically only require a PE endorsement, not a full QP submission. QP.sg will advise during the initial consultation which service applies to your project — at no charge. See PE Endorsement →
Er. David Zheng is formally appointed as QP (Structural) via a signed QP Appointment form submitted to BCA. This establishes legal responsibility for the structural design and supervision of the works.
Structural drawings and calculations are prepared in accordance with BCA's structural requirements and Singapore's Eurocodes (SS EN 1992–1995). All documents are PE-endorsed by Er. David Zheng (#4385).
The full submission package — drawings, calculations, forms, and supporting documents — is filed through BCA's CORENET electronic submission system. QP.sg manages this process end-to-end.
BCA reviews the submission and may raise Requests for Information (RFIs). QP.sg coordinates all technical responses and resubmissions until written approval is obtained.
Where required under BCA's supervision requirements, site inspections at key structural stages are carried out. Supervision records and completion certificates are prepared for BCA filing.
Upon completion of structural works, QP.sg prepares and submits the Completion Certificate to BCA, formally closing the QP's appointment for the project.
This is the most common question we receive. The table below summarises the key differences.

| Typical trigger | HDB, MCST, landlord, temporary works | BCA building plan approval required |
| Regulatory basis | Professional Engineers Act | Building Control Act |
| Authority submission | Not always required | Always — via BCA CORENET |
| Ongoing supervision | Not required | Required at key stages |
| Completion cert | Not required | Required for BCA sign-off |
| Typical fee range | S$500 – S$1,500 | S$1,500 – S$8,000+ |
| Typical timeline | 3–10 working days | 4–16 weeks (incl. BCA review) |

BCA CORENET (Construction and Real Estate Network) is Singapore's e-submission system for building plan approvals. As the building owner, you do not manage CORENET yourself — this is handled entirely by your appointed QP. QP.sg manages the full CORENET submission process including drawing uploads, form submissions, payment of BCA processing fees, and response to authority queries.
Yes. QP.sg can serve as QP (Structural) and coordinate directly with your appointed architect (QP Architectural) or builder. We manage the structural submission track of the BCA approval independently, and liaise with other consultants and the authority on structural matters throughout the process.
BCA's processing time varies by project type and submission completeness. Straightforward landed property A&A submissions typically receive first response within 4–8 weeks. Complex or incomplete submissions can take longer due to RFI cycles. QP.sg prepares submissions to maximise the likelihood of first-pass approval without RFIs, which is the most effective way to reduce overall approval time.
To initiate a QP submission, you typically need to provide:
If you don't have all of these, contact us — we can advise what's essential and what can be obtained during the process.
No. Initial consultations and scope assessments are complimentary. WhatsApp Er. David at +65 9800 4385 or use the contact form. We will confirm whether your project requires QP submission or PE endorsement, and provide a fixed-fee quotation before any work begins.
