Structural engineer fees in Singapore are not set by a published tariff. They are negotiated for each engagement and depend on the building type, the scope of work, the number of authorities involved and the level of risk in the design. This guide explains how fees are built up, which statutory charges sit outside the consultant’s fee, and how to compare quotations on a like-for-like basis.
TL;DR
- No mandatory fee scale exists for structural engineering consultancy in Singapore, so every quotation reflects the firm’s assessment of scope, complexity and risk.
- Statutory plan fees payable to the Building and Construction Authority (BCA) are separate from consultancy fees and follow a published schedule, for example $200 per storey for residential A/A works with a structural plan submission.
- Fees rise with non-conforming designs, deep excavation, complex building types and multi-agency coordination under CORENET X.
- A quotation should state clearly whether it covers design, authority submission, site supervision, As-Built records and TOP/CSC support.
- Stellar Structures does not publish fixed prices; fees are quoted per engagement after the scope is reviewed.

Is There a Standard Fee Scale for Structural Engineers?
There is not. In its advice on consultancy fees in the built environment sector, the Competition and Consumer Commission of Singapore (CCCS) advised against standardized fee guidelines, noting the risk that they may lead to fee clustering. Clients are encouraged to select firms on service quality, track record and technical capability, not on the lowest price alone.
In practice this means two quotations for the same project can differ considerably, and the difference is often a difference in scope, not in efficiency. A low figure that excludes revisions, site inspections or As-Built documentation is not comparable with a higher figure that includes them.
How Structural Engineers Charge
Three charging models are common for consultancy work in Singapore. The appropriate one depends on how well the scope can be defined at the outset.
| Model | Typical use | Advantage | Point to watch |
|---|---|---|---|
| Lump sum (fixed fee) | Defined scope such as a landed house A&A, a mezzanine or a single authority submission | Cost certainty for the owner | Variations and extra submission rounds must be priced in the agreement |
| Hourly basis | Advisory work, site assessments, design reviews, early feasibility opinions | Suits an uncertain or small scope | Total cost depends on the hours consumed |
| Percentage or staged fee | Larger developments with phased design, tender and construction stages | Fee tracks the stage of work | Percentage base (construction cost estimate) should be agreed in writing |
Stellar Structures offers structural and architectural consultation on an hourly basis as well as project-based engagements. Details of the service lines are on our services page. For a fuller explanation of how a consultation is priced, see our article on structural engineer consultation cost.
Statutory Plan Fees: A Separate Line in the Budget
Owners frequently combine two different charges. The consultant’s fee pays for professional design, calculation, coordination and certification. The plan fee is a statutory charge payable to the authority when plans are lodged. The BCA’s schedule under the Building Control Regulations sets out how structural plan fees are computed.
Per the BCA’s plan fee schedule, as of October 2025:
| Type of works | Rate |
|---|---|
| New SGFA, general building, below sub-level | $400 per 100 m² |
| New SGFA, general building, above sub-level (first 2,500 m²) | $300 per 100 m² |
| New SGFA, general building, above sub-level (subsequent area) | $270 per 100 m² |
| A/A works, residential building, with structural plan submission | $200 per storey |
| A/A works, non-residential building, with structural plan submission | $400 per storey |
The BCA has also published a Building Plan and Structural Plan Fee page for projects whose first set of plans was submitted on or after 30 December 2024, which should be checked for the current computation before budgeting. Other agencies charge their own fees. For a landed house A&A, the URA directs applicants to its Development Control Fee Schedule for the lodgment fee, so those amounts are also separate from the engineer’s fee.
A sound budget therefore lists three groups of cost: consultant fees, statutory fees, and the cost of any approvals-related work such as inspections or surveys. Owners of commercial property will also recognize that ongoing compliance and upkeep sit in yet another budget. As an illustration of how recurring building maintenance can be bundled into one contract with fixed response times, see this example of planned and reactive commercial maintenance contracts in London; the structure differs from Singapore practice, but the budgeting principle of separating one-time approval costs from recurring upkeep applies equally.
What Makes Fees Higher or Lower
Structural engineering fees are not commodity-priced. Professional bodies use complexity frameworks to estimate the effort required. The Association of Consulting Engineers Singapore’s Accredited Checker Value Articulation Framework is one such document, and it reflects the same principle: fees follow the level of professional effort and responsibility, not the size of the drawing set alone.
Factors that typically raise the fee
- High-risk geotechnical conditions. Deep basements, soft marine clay, excavation near existing structures or MRT protection zones require additional analysis, instrumentation planning and temporary works design. Our foundation engineering guide sets out how geotechnical design affects structural systems and cost.
- Non-conforming or unusual structural systems. Transfer structures, long spans, retained existing structures with unknown as-built details and unconventional materials demand more checking and more iterations.
- Complex building types. The BCA has refined the definition of complex building types in a circular on complex buildings, and failure to identify a building correctly or to consult the BCA beforehand can cause delays and re-submissions.
- Number of agencies. A project needing BCA, URA, SCDF, PUB, LTA and NEA input requires more coordination than a single-agency submission.
- Compressed programmes. Fast-track schedules need parallel working and more senior involvement.
Factors that typically keep the fee contained
- A clear brief, complete architectural drawings and existing records provided at the outset.
- A conforming, regular structure with conventional spans and materials.
- A single authority submission with a defined scope.
- Early appointment of the engineer, so that structural coordination is not retrofitted.
How CORENET X Has Changed the Scope of the Fee
Under CORENET X, the gateway process brings structural engineers into the Design Gateway (G1) and the Construction Gateway (CG, also referred to as G2). Compared with paper-based 2D workflows, the engineer’s time now includes BIM model integration, inter-agency dialogue and coordination of requirements that must be resolved before main structural works begin.
The same source indicates a service level of 15 working days for BCA’s independent structural submissions, while integrated G2 submissions involve several agencies and generally carry a collective response time of 20 working days. Programme planning should allow for these periods, and a fee proposal should state how many submission rounds and clarification cycles it includes.
For projects near the size thresholds that trigger the integrated process, our article on the 5,000 sqm threshold and CORENET X delays explains how qualified persons plan around them.
What a Quotation Should Spell Out
Before comparing figures, confirm that each quotation addresses the following items.
- Design scope: structural analysis and design, temporary works, geotechnical input, and whether architectural and M&E coordination is included.
- Authority submissions: which agencies (BCA, URA, HDB, JTC, SCDF, PUB, LTA, NEA, NParks) and how many rounds of comments are covered.
- PE certification: for a landed house A&A or rebuild, the Professional Engineer’s certification is a regulatory requirement. The URA’s A&A guidelines for landed housing call for a PE certification confirming that retained structures are sound, can accommodate the new works, and that appropriate construction methods will be used.
- Site supervision and records: site supervision reports and As-Built documentation are generally needed at the completion stage, so omitting them from the original appointment can delay TOP/CSC.
- Variations: the hourly rate or the method for pricing changes in design or scope.
- Exclusions: surveys, soil investigation, design checks and inspections that are billed separately.
Our guide on BCA submission from BP to TOP shows where each of these items falls in the approval sequence.
Why the Lowest Fee Is Rarely the Lowest Cost
The CCCS advice cited above steers clients toward track record and technical capability. The reasoning is practical: structural integrity is a legal requirement, and delays from incomplete documentation or an unresolved regulatory gateway can exceed the savings from a cheaper appointment. A rejected or repeatedly queried submission extends the programme, and prolonged programmes carry financing, preliminaries and rental costs.
The cost of late compliance is also material. Our analysis of BCA fines versus regularisation costs explains why early plan submission is generally cheaper than regularising works afterward. Contractors preparing submissions should also read the structural plan approval guide for contractors.
Our Perspective
We see fee discussions go wrong in one consistent way: the client compares totals before comparing scopes. A structural fee is the price of a defined body of responsibility, namely design, checking, certification, coordination and the records that the authorities require at TOP/CSC. When one of those elements is missing from a quotation, it reappears later as a variation or as a delay.
Our practice is led by a Professional Engineer with decades of experience in Singapore infrastructure, and we handle submissions across the statutory boards, from BCA and URA to JTC, SCDF and PUB. That coverage allows us to price the whole approval path at the outset instead of in fragments. We therefore ask for drawings, site records and the intended programme before issuing a proposal, and we state what is included, what is excluded and how changes will be handled. We do not publish fixed prices, because a figure without a reviewed scope would mislead more than it would inform.
For uncertain or early-stage questions, such as whether a wall can be removed or whether an existing structure can be retained, an hourly consultation is often the proportionate starting point. For defined scopes, a lump sum with clear exclusions gives the owner certainty.

FAQ
How much should I pay for a structural engineer in Singapore?
There is no regulated or standard amount, so the right figure is the one that matches a clearly defined scope. Statutory plan fees, such as the BCA’s $200 per storey for residential A/A works with a structural plan submission, are additional to the consultant’s fee. Request itemized quotations from at least two qualified firms and compare scope before price.
How do structural engineers charge?
Most charge by lump sum for a defined scope, by the hour for advisory and review work, or by a staged or percentage fee on larger developments. The agreement should state the number of authority submission rounds and how variations are priced.
Who pays for a structural engineer?
The party that appoints the engineer pays the fee, which is usually the property owner or developer. On design-and-build projects the contractor may appoint the engineer, in which case the cost is carried inside the contract sum. Statutory plan fees are paid by the applicant at lodgment.
Does the fee include approval from BCA, URA and other authorities?
Only if the proposal says so. Design, authority submission, site supervision and As-Built documentation are distinct tasks, and each should be listed. Confirm the agencies covered and the number of comment rounds included.
