Authority fees for a Temporary Occupation Permit are generally modest or, in the case of fire safety submissions, nonexistent, so the figure that actually determines a project’s TOP budget is professional and remedial spending. BCA and SCDF publish transparent charges through CORENET X, but the real cost driver is the Qualified Person’s coordination, inspection and rectification work. Firms such as Aman Engineering Consultancy exist precisely because that gap between statutory fees and total project cost is where budgets slip.
TL;DR:
- Professional and remedial costs, especially coordination and inspection work, are the main drivers of TOP project budgets rather than fixed authority fees.
- Express inspection fees cost $3,000 and are useful only if a project faces delays that would outweigh this expense, unlike standard processing which is cheaper but slower.
- Fire safety submissions through SCDF typically have no application fee if lodged via CORENET by the Qualified Person, with only small fees for renewal processes.
- Early involvement of multidisciplinary experts and pre-inspection mock audits significantly reduce delays and unexpected costs during TOP approval.
- Payment methods for authority and plan fees, such as PayNow or card payments, influence how quickly processing begins, with faster payment verification speeding up approvals.

Authority fees to budget: BCA, plan fees and SCDF charges
Project teams frequently conflate government fees with consultancy costs, and the two categories behave very differently. Authority charges are fixed, published and easy to verify. Consultancy costs are variable, project-specific, and where most of the money actually goes.

For a standard TOP or Certificate of Statutory Completion application, BCA’s TOP/CSC guidance sets out the process steps, required forms, and the minimum lead time needed for QP documentation such as the Certificate of Supervision and declarations before an inspection date can be confirmed. Teams that submit these documents late routinely lose their inspection slot regardless of how ready the building is.
Express processing carries its own separate tiers. For an Express TOP application, the fee is $500 for building works up to 3,000 square meters and $1,000 for building works exceeding that threshold. A different charge applies when a team wants the on-site inspection itself expedited rather than just the application processing.
- BCA’s express onsite inspection can be arranged within roughly four days of request, subject to project size and inspector availability.
- The express inspection charge is $500 for projects up to 3,000 square meters and $1,000 above that, separate from the $3,000 express inspection fee for the expedited on-site visit itself.
- Plan fees for related temporary structures are calculated at $200 for every 100 square meters of gross floor area, or $200 per structure where that area calculation does not meaningfully apply.
The statistic: the express inspection fee is $3,000, a cost worth weighing against the daily expense of a delayed handover or lease start date.
Fire safety submissions follow a different rule entirely. SCDF’s guidance on the Fire Safety Certificate and Temporary Fire Permit confirms there is no application fee for TFP or FSC submissions, provided they are lodged through CORENET by the Qualified Person. Some building types carry small administrative charges tied to Fire Certificate renewal, but the core TFP/FSC lodgement itself costs nothing at the authority level. For private property owners navigating this process for the first time, Aman’s guide to SCDF submission and fire safety certificate procedures walks through the documentation sequence in more detail.
Why consultancy, QP and inspection costs typically dominate the budget
The Qualified Person is the professional, usually a registered architect or engineer, who prepares statutory submissions, supervises construction against approved plans, signs the required declarations and coordinates the various inspections that authorities demand before granting TOP. This role is not optional and it is not administrative. It is the mechanism through which a building’s physical state gets translated into a form the government will accept.
The professional fee categories that follow from this role tend to fall into a few recurring buckets:
- Statutory submission package preparation, including drawings, schedules and declarations tailored to each agency’s requirements.
- Site inspections and specialist testing, covering structural, facade and fire safety systems ahead of the formal authority visit.
- Remedial supervision, meaning the coordination needed when an inspection flags a defect that must be fixed and re-verified.
- PE endorsements and third-party specialist input for mechanical, electrical or facade-specific concerns that fall outside general QP scope.
Cost drivers vary by project, and teams that assume a flat consultancy fee across every building type usually end up surprised. A high-rise with a complex facade will demand more specialist testing than a low-rise warehouse. A project pursuing partial TOP, where sections of a building are cleared for occupation ahead of the rest, multiplies coordination effort because each phase effectively runs its own mini-submission. Unexpected defect rectification, discovered only once inspectors are on site, is the single biggest source of budget overrun on TOP projects.
Pro Tip: Build a contingency of roughly 10 to 15% into professional and remedial line items rather than the authority fee lines, since that is where genuine variability lives.
Facade complexity in particular tends to surprise teams that budgeted only for a standard inspection scope. Details on what a proper structural review actually covers are laid out in Aman’s explanation of what a structural inspection includes, which is a useful reference when scoping consultant proposals against actual deliverables rather than a generic line item.

Payments and CORENET X mechanics: methods, limits and processing speed
CORENET X governs how both authority fees and plan fees get paid, and the payment method chosen has practical consequences for how quickly processing begins. A circular on updated CORENET X payment methods, effective February 13, 2026, introduced PayNow as a payment option alongside existing card and bank transfer methods, along with revised thresholds for each.
| Payment method | Typical use case | Processing implication |
|---|---|---|
| Credit or debit card | Smaller submission fees | Fastest verification, processing starts almost immediately |
| PayNow | Larger sums, introduced February 2026 | Faster verification than bank transfer for high-value payments |
| Bank transfer | Large plan fee payments | Requires proof-of-payment upload for verification to proceed |
Processing on any given application begins only once the payment has been verified, so a bank transfer without an uploaded proof of payment can sit unprocessed for days while a card payment on the same submission would already be moving. For large plan fee payments tied to bigger developments, CORENET X’s submission workflow guidance recommends using the portal’s Fee Computation feature ahead of time and notes that fees below $10,000 are generally best paid by card for speed. Teams running partial TOP phasing should plan payment routing for each phase separately, since a bottleneck on one phase’s payment verification can hold up the entire schedule.
Practical checklist to reduce TOP costs and avoid inspection delays
Most cost overruns on TOP applications come from avoidable rework, not from the statutory fees themselves. A disciplined pre-submission process is the cheapest insurance a project team can buy.
- Commission a QP-led mock inspection before the official one, covering structural, facade and fire safety items that authorities typically flag.
- Use CORENET X’s pre-submission consultation feature to confirm partial TOP phasing plans with all relevant agencies before locking in a schedule.
- Run specialist testing on facade and structural elements early enough that any rectification does not sit on the critical path to the inspection date.
- Build a rectification contingency into the schedule rather than assuming a clean pass on the first attempt.
- Reserve express inspection as a deadline tool, not a default, and weigh its $3,000 charge against the actual cost of delay for that specific project.
Guidance on how to prepare for a facade-specific review without last-minute surprises is covered in Aman’s piece on passing facade inspection without delays, which pairs well with the mock-audit approach above.
Pro Tip: Bundle specialist testing procurement across disciplines where possible. Coordinating structural, facade and fire consultants on a single site visit schedule cuts overhead compared to booking each separately.
Why early expert involvement is the real fee-saving move
Authority fees are the easy part of a TOP budget. They are published, fixed and simple to plan around. What consistently derails schedules and inflates costs is poor coordination between the QP, specialist consultants and the authorities, usually because a submission was rushed or a defect was found too late to fix without delay.
Some engineering consultancies work across statutory submissions, authority approvals, inspections and BIM coordination on projects spanning multiple agencies including BCA and SCDF. That multidisciplinary structure, rather than any single fee number, is what tends to keep a TOP timeline intact.
Get the coordination right early, and the authority fees take care of themselves.

How Aman Engineering Consultancy supports TOP submissions
Consultancy firms offer routes through the parts of TOP preparation that carry the most cost risk: authority approvals, structural and facade inspections, fire safety certificate submissions, PE endorsements and BIM coordination across disciplines. 
- Authority Approvals covering PSI, PFI and FSC submission coordination.
- Real Estate Inspection services for teams needing a scoped assessment before booking an official inspection.
- Project Management support for phased or partial TOP schedules.
| Service | What it addresses |
|---|---|
| Authority Approvals | PSI, PFI, FSC statutory submissions |
| Real Estate Inspection | Pre-inspection scoping and reporting |
| Project Management | Phasing and multi-agency coordination |
A pre-submission review or mock inspection engagement is the most direct way to see where a specific project’s risk sits before authority inspectors do. Reach out through Amanengineering to request one.

FAQ
Does BCA charge a standard fee for every TOP application?
Standard TOP and CSC applications are processed under BCA’s normal workflow, while express processing carries its own fee, $500 for projects up to 3,000 square meters and $1,000 above that, according to BCA’s guidance. The express on-site inspection itself carries a separate $3,000 charge.
Is there a fee for SCDF fire safety submissions related to TOP?
No, SCDF does not charge an application fee for Temporary Fire Permit or Fire Safety Certificate submissions when lodged by the Qualified Person through CORENET. Some Fire Certificate renewals carry small administrative charges depending on building type.
What changed with CORENET X payments in 2026?
CORENET X added PayNow as a payment method effective February 13, 2026, alongside existing card and bank transfer options, as documented in the payment methods circular. Processing on a submission begins only after payment verification, so the chosen method affects how quickly work starts.
Why do professional fees usually cost more than authority fees?
Authority fees are fixed and published, while professional fees cover statutory submission preparation, site inspections, specialist testing and remedial supervision, all of which scale with a project’s size and complexity. Unexpected defect rectification discovered during inspection is typically the largest source of budget overrun on a TOP project.
When is an express TOP inspection worth the extra cost?
An express inspection is worth its $3,000 fee when the cost of schedule delay, such as a lease start date or handover commitment, exceeds that amount, based on the fee structure in BCA’s TOP/CSC guidance. It should be treated as a deadline tool rather than a routine step in every submission.
