A resident engineer whose accreditation has lapsed is a problem you want to find before the job starts, not halfway through it. Resident engineer accreditation in Singapore is the first thing to check when you hire an RE or take one on contract.
The law regulates supervision of the structural side of construction, so the check matters early. This guide covers who needs it, how a civil and structural RE gets accredited, and how to confirm an accreditation is current.

ToggleWho needs to be an accredited resident engineer
The Institution of Engineers, Singapore (IES) says on its C&S RE/RTO registry page that the Building Control Act requires qualified site supervisors to assist the Professional Engineer (PE). They supervise the structural aspects of construction works. Since 15 February 2009, every qualified site supervisor has needed accreditation with the IES-ACES Joint Accreditation Committee (JAC). The title is civil and structural (C&S) resident engineer or resident technical officer.
The scope is narrower than many job ads suggest. That page adds that the Building Regulation does not require accreditation for supervising non-structural work. It also says a PE with a valid practising certificate does not need JAC accreditation to supervise structural works. The table shows who falls where.
| Person | Accreditation as C&S RE or RTO |
|---|---|
| Qualified site supervisor of structural works who is not a PE | Mandatory since 15 February 2009 |
| PE with a valid practising certificate from the Professional Engineers Board | Not required; can register as site supervisor with the PE number in CORENET |
| Supervisor of non-structural work | Not required by the Building Regulation |

How a C&S resident engineer gets accredited
IES sets out the RE routes based on Building and Construction Authority (BCA) regulations. A degree in civil or structural engineering recognised for PE registration needs no extra experience. Degrees from universities on the Commissioner of Building Control’s list need one year. One of the supervising PEs must endorse and sign the application form.
| Route | Practical experience required |
|---|---|
| University degree in Civil or Structural Engineering recognised for PE registration | None |
| Master’s or doctoral degree in Civil or Structural Engineering (with an accredited bachelor’s degree) | None |
| Chartered Engineer registered by the Engineering Council UK in civil or structural engineering | None |
| Degree in Civil or Structural Engineering from a university specified by the Commissioner of Building Control | 1 year of postgraduate local experience in design or construction of structural works |
The application fee is S$21.80 including GST, and IES says processing takes about two months under normal circumstances. From 1 September 2026, applicants must hold the original diploma or degree certificates and transcripts before applying. Foreign applicants also need a background screening company recognised by the Ministry of Manpower (MOM) to verify their qualifications. Tell candidates early, because these steps add time.
RE renewal: what a current accreditation looks like
IES charges S$65.40 for renewal, paid through its portal. For an RE who last renewed in the previous calendar year, it asks for up to three Performance Assessment Reports from the past 12 months. If the person supervised no project, an employer letter replaces the reports. It also asks for proof of training worth 6 structural and 2 safety Supervision Training Units.
Someone who last renewed one to two calendar years ago needs 9 structural and 2 safety units. Anyone aged above 65 needs a medical letter.
An accreditation that lapsed for more than three calendar years means starting again under the rules that apply at re-application. So ask for the renewal date and the training record, not only the accreditation number. It takes five minutes, and it tells you whether the person has been supervising recently.
What to check when you hire a resident engineer
Start with the IES list of registered C&S REs and RTOs, which the registry page links to. Confirm the name and current status. For tunnel work, IES points to a separate list of RE and RTO (Tunnel) applicants on the TUCSS website, so ask which one applies. New starters can take the Building Control Regulations for Site Supervisors course that BCA Academy runs with the JAC.
- Ask for the accreditation number, the last renewal date and the supervising PE who endorsed the application.
- Ask what structural work the person has supervised, such as foundations, steelwork or concrete, and on which projects.
- Confirm who they will report to on your project and which PE they will work under.
- Check the notice period and the project end date before agreeing a start.
Contract or permanent resident engineer?
A contract RE fits a project with a defined programme, because the accreditation and the supervising PE arrangement tie to the job. Permanent hires make sense when you run structural projects back to back and want continuity between them. Our post on contract staffing for project-ready teams explains how fixed-term placements work.

How ProSkill Workforce supplies resident engineers
ProSkill Workforce lists resident engineers among its engineering professionals, next to resident technical officers. Our existing guides cover the job itself. They are the role of a resident engineer in Singapore, what a resident engineer does and the RE in construction. The page on RE and RTO service providers in Singapore covers how we place both.
For wider project needs, see construction manpower supply. Foreign candidates should read our guide to the Employment Pass, S Pass and Work Permit.
Resident engineer accreditation: frequently asked questions
Is accreditation mandatory for a resident engineer in Singapore? For supervising the structural aspects of construction, yes. IES says all qualified site supervisors have needed accreditation with the JAC as a C&S RE or RTO since 15 February 2009. The Building Regulation does not require it for non-structural work.
Does a Professional Engineer need to be accredited as an RE? No. A PE with a valid practising certificate from the Professional Engineers Board does not need JAC accreditation to supervise structural works. The PE can register as a site supervisor using the PE registration number in CORENET.
What qualification does a resident engineer need? A degree in civil or structural engineering recognised for PE registration, a master’s or doctoral degree in the same field, or UK Chartered Engineer status in it, with no extra experience. Holders of a degree from a university specified by the Commissioner of Building Control need one year of experience.
How much does RE accreditation cost and how long does it take? IES lists an application fee of S$21.80 including GST and says processing takes about two months. Renewal costs S$65.40. It takes about two weeks normally, or six to eight weeks in peak periods, according to IES.
What is needed to renew an RE accreditation? Performance Assessment Reports from the past 12 months, or an employer letter if there was no project. You also need training units in structural and safety topics, and a medical letter if you are above 65. The number of units depends on when the accreditation was last renewed.
