How to Become a Quantity Surveyor in Singapore (2026 Guide)

Quantity surveying is one of the most stable and consistently in-demand professions in Singapore's built environment sector. With major infrastructure projects like the Cross Island Line, Changi Terminal 5, and Jurong Lake District development running well into the 2030s, qualified quantity surveyors (QS) are needed at every stage of the construction lifecycle. This guide covers the education paths, registration requirements, and career progression you need to become a registered QS in Singapore.

What Does a Quantity Surveyor Do in Singapore?

A quantity surveyor manages the financial and contractual aspects of construction projects from inception to completion. This is distinct from engineering, which focuses on technical design, or project management, which focuses on programme and delivery. The QS role sits at the intersection of law, finance, and construction.

Core responsibilities include:

Cost estimation: Preparing preliminary and detailed cost estimates at different design stages
Bills of Quantities (BOQ): Producing itemised lists of materials, labour, and work packages for tendering
Tendering and procurement: Evaluating contractor bids and advising clients on contractor selection
Contract administration: Managing JCT, FIDIC, or Singapore Institute of Architects (SIA) contracts, handling variation orders and progress claims
Final accounts: Settling the financial close-out of a project at completion

In Singapore, QSs work for developer clients, government agencies (HDB, LTA, JTC), or QS consultancies. Major international consultancies with Singapore offices include AECOM, Turner and Townsend, and Rider Levett Bucknall (RLB).

Education Pathways: Diploma vs Degree

Diploma Route (3 years)

Singapore Polytechnic and Ngee Ann Polytechnic both offer diplomas in Building and Real Estate or Quantity Surveying. These are practical, industry-linked programmes that prepare graduates for entry-level QS roles. Diploma holders can enter the workforce as graduate QSs and work toward SISV membership over time.

Diploma graduates who want to progress to full SISV membership faster sometimes pursue a part-time degree conversion later in their careers.

Degree Route (3-4 years)

A degree is increasingly preferred by large consultancies and government agencies. Universities offering relevant programmes include:

NUS (Bachelor of Science in Project and Facilities Management)
SIT (Bachelor of Science in Construction Management, offered in partnership with University of Glasgow)
RMIT-SIM (Bachelor of Applied Science in Construction Management)

Degree graduates typically enter at a higher grade and progress faster toward Registered QS (RQS) status.

Career Switchers

SIM Global Education offers conversion programmes for graduates from other disciplines who want to enter the construction industry. These typically take one to two years part-time and include industry mentorship components.

Step-by-Step Guide to Becoming a Quantity Surveyor in Singapore

Step 1: Complete your diploma or degree

Choose your institution based on your budget, timeline, and whether you prefer a full-time or part-time route. Polytechnic diplomas are a cost-effective entry point; a degree positions you for faster progression.

Step 2: Join a QS firm or client-side organisation as a graduate QS

Your first role involves learning on the job under a senior QS. Expect to spend significant time on BOQ preparation, cost reporting, and site measurements. Large consultancies like Turner and Townsend, RLB, and AECOM run structured graduate programmes with rotation across project types.

Step 3: Join SISV as a Graduate Member

The Singapore Institute of Surveyors and Valuers (SISV) is the professional body for quantity surveyors in Singapore. Apply for graduate membership early in your career. This requires submitting your educational qualifications and beginning your experience log.

Step 4: Accumulate five years of relevant experience

SISV Full Membership and the Registered QS (RQS) designation through the Singapore Institute of Quantity Surveyors (SIQSV) both require a minimum of five years of post-qualification experience. Document your experience carefully, including project types, values, and your specific responsibilities on each contract.

Step 5: Apply for SISV Full Membership and RQS registration

Sit the professional review, which includes a written submission and an interview with an SISV panel. This is the equivalent of chartership in the UK (MRICS). Once awarded, you are recognised as a fully registered quantity surveyor in Singapore and are authorised to sign off on certain statutory documents.

Step 6: Progress to senior QS, associate director, or client-side roles

With RQS registration, you are positioned for senior roles at consultancies, or for a move to the client side at HDB, LTA, JTC, or major property developers.

Key Skills Employers Want

Cost estimation and BOQ preparation: The core technical competency. Accuracy and speed matter
Contract knowledge: SIA and PSSCOC (Public Sector Standard Conditions of Contract) are the dominant forms in Singapore
BIM tools: CostX is the leading 5D BIM quantity take-off tool in Singapore. Revit is increasingly expected for reading building information models
Spreadsheet and cost management software: Excel remains central; platforms like Procore and CostOS are growing
Negotiation and communication: QSs spend significant time negotiating with contractors and advising clients

FAQ

Do I need a degree to become a quantity surveyor in Singapore?

No, but it helps. A diploma from Singapore Poly or Ngee Ann Poly is a valid entry point and many experienced QSs built successful careers starting with a diploma. However, large international consultancies (AECOM, Turner and Townsend, RLB) and government agencies (HDB, LTA) generally prefer degree-qualified candidates for graduate hires. If you start with a diploma, consider a part-time degree conversion once you have two to three years of experience.

What is SISV and why does it matter?

SISV (Singapore Institute of Surveyors and Valuers) is the statutory and professional body for surveyors in Singapore, operating under the Surveyors Act. SISV Full Membership is the recognised professional credential for quantity surveyors in Singapore, equivalent to chartered status in the UK (MRICS). Many government tenders and large private projects require the lead QS to hold SISV Full Membership. Without it, you cannot progress beyond a senior associate level at most major consultancies.

How long does it take to become a Registered QS in Singapore?

Assuming you start with a three-year degree and join a consultancy immediately, you are looking at a minimum of eight years from starting university to achieving Registered QS (RQS) status: three to four years of study plus five years of post-qualification experience. The five-year experience requirement cannot be shortened, but the quality and breadth of your project experience can make your professional review application stronger and reduce the likelihood of a failed submission.

Is BIM knowledge required to become a QS in Singapore?

BIM literacy is increasingly expected rather than optional. The Building and Construction Authority (BCA) has mandated BIM submission for all projects above a certain value threshold in Singapore, which means QSs on these projects must be able to read BIM models and use 5D BIM tools like CostX to extract quantities. Graduates who are proficient in CostX and familiar with Revit have a clear advantage in the graduate job market. If your institution does not offer BIM training, seek out SkillsFuture courses to fill the gap.
