When planning renovations, additions & alterations (A&A), or any construction work in Singapore, one of the most common points of confusion is whether a Professional Engineer (PE) endorsement or an Architect endorsement is required for authority submissions. Both serve important but distinct purposes in the building and regulatory process.

In this article, we clarify the key differences between PE endorsement and Architect endorsement, and help you understand when you need each for your project.

What is PE Endorsement?

PE Endorsement refers to the certification provided by a Professional Engineer (PE) registered with the Professional Engineers Board (PEB) Singapore. A PE endorsement is typically required when the works involve structural, mechanical, electrical, or geotechnical safety considerations.

Examples of Works Requiring PE Endorsement:

• Structural modifications (e.g., hacking structural walls, adding mezzanine floors)

• Design and installation of mechanical ventilation or ACMV systems

• Electrical works requiring authority submission (SP Group, EMA)

• Temporary works such as ERSS (earth retaining structures)

• Fire protection systems (sprinklers, alarms, etc.) for SCDF submissions

• Geotechnical works (soil investigation, piling)

The PE’s role is to certify the design’s compliance with safety standards and statutory requirements. Without this endorsement, submissions to agencies like BCA, SCDF, PUB, LTA, JTC will not be accepted.

What is Architect Endorsement?

An Architect endorsement comes from a Registered Architect (RA) listed with the Board of Architects (BOA) Singapore. Architects typically handle the design, spatial planning, and aesthetic aspects of a building project. Their endorsement is focused on the architectural integrity and regulatory compliance of the building design (especially with URA guidelines, BCA building control regulations, and other planning considerations).

Examples of Works Requiring Architect Endorsement:

• New building developments (residential, commercial, industrial)

• Major A&A works involving façade changes

• Re-zoning or change of use submissions to URA

• Compliance with GFA (Gross Floor Area), site coverage, building setbacks

• Projects requiring Qualified Person (QP) submission as per BCA guidelines

An architect’s role is crucial where planning permission, aesthetics, and compliance with land use or building design guidelines are concerned.

PE Endorsement vs Architect Endorsement: Key Differences

When Do You Need Both PE and Architect Endorsements?

In many larger-scale projects (new builds, major renovations), both endorsements are required. For example:

• The Architect handles the overall design, planning submissions, and URA compliance.

• The PE certifies the safety of the structural, M&E, and fire safety aspects.

Having both professionals ensures that your project complies with both planning and engineering regulations, reducing the risk of costly delays.

Why Does This Matter for Your Project?

Failing to obtain the right endorsements can lead to:

• Rejected submissions to BCA, URA, SCDF, or other agencies

• Project delays and additional costs

• Non-compliance penalties

• In extreme cases, unsafe structures with liability risks
