There is no standard published price for a ConSASS audit in Singapore. The fee is quoted per worksite and depends on project scale, the number of audit cycles, the size of the audit team and how mature the site’s safety and health management system (SHMS) already is. The audit itself is a recurring regulatory obligation for large worksites, so the more useful budgeting question is the cost of the whole audit programme across the project, not the cost of a single visit.
TL;DR
- ConSASS fees are quoted per project. No official tariff exists, and no fixed figure applies across worksites.
- A worksite with a contract sum of S$30 million or more must appoint an approved independent auditing organization at least once every six months, so the cost recurs for the project’s duration.
- Fee drivers include worksite size, the number of elements to audit, team size (a minimum of two auditors), documentation readiness and any follow-up verification.
- Preparation, gap assessments and corrective-action checks are usually scoped separately from the audit itself, so ask for the scope in writing.
- BizSAFE and ISO certification are priced on different logic from ConSASS, and should be budgeted as separate line items.

Why a ConSASS audit has no fixed price
The Construction Safety Audit Scoring System, or ConSASS, is the Ministry of Manpower’s (MOM) standard protocol for auditing a construction SHMS. MOM sets the protocol, the checklist and the reporting channel. It does not set what an auditing organization charges. Each firm prices its own engagement, which is why searching for a single number returns course fees and unrelated statutory audit ranges rather than a ConSASS tariff.
One figure that does appear in official documents is not a client fee. Under MOM’s circular on accreditation and report submission, auditing organizations pay MOM $110 for each auditor registered through the WSH eService. That is an overhead the auditing organization carries, and it is a reminder that a quote reflects accredited, registered personnel rather than a generic inspection.
A price therefore has to be built from scope. The sections below set out what that scope contains.
When the obligation applies, and how often the cost recurs
The regulatory trigger is the contract sum. According to the MOM ConSASS User Guide, a worksite with a contract sum of S$30 million or more must appoint an approved independent external auditing organization to audit its SHMS at least once every six months. The same guide notes that Regulation 9 requires construction-worksite occupiers to appoint a WSH auditor on that six-monthly cycle.
For budgeting, the consequence is arithmetic. A 30-month project implies roughly five audit cycles, each with its own fieldwork, reporting and submission effort. A quote for a single audit can look modest, while the programme total is what reaches the project cost plan. Contractors should request pricing both per cycle and for the full project duration, with a stated assumption about how many cycles the schedule requires.
For a closer reading of the threshold and cycle timing, see our explanation of when ConSASS is required for construction and the S$30M trigger and checklist for occupiers.
What determines the fee
Worksite scale and complexity
The ConSASS checklist contains 204 questions grouped into three bands: Band I tests how comprehensive and documented the SHMS content is, Band II tests whether the provisions are implemented well on site, and Band III covers best practices. A large multi-trade site with several work fronts, heavy lifting, excavation or work at height generates more to inspect and more workers to interview than a compact single-trade project. Audit duration, and therefore fee, follows that breadth.
Team size and audit methodology
The protocol is prescriptive. All SHMS audits using ConSASS must be conducted by a team of at least two WSH auditors. The typical methodology covers an opening meeting, a familiarization tour, interviews with system owners and document reviews, a physical condition inspection, interviews with workers, a team debrief and a closing meeting. Every one of those steps consumes auditor time, and a minimum two-person team sets a floor under the price. A quote that appears far below the market for a large site should prompt a question about team composition and the days allocated.
Documentation readiness
Band I rewards documented systems. Where procedures, risk assessments, training records and inspection logs are complete and traceable, the document review proceeds quickly. Where they are fragmented across subcontractors, auditor time rises, and so does the likelihood that the findings need a second round of evidence. Our guidance on preparing ConSASS documentation correctly addresses this directly.
Reporting and submission
The auditor does not simply issue a report to the client. The audit report must be submitted to MOM through the WSH eService portal, where the auditor completes the audit particulars and the ConSASS scorecard, and attaches the checklist, scorecard, interview sheets and final audit report. Report preparation and filing are part of the engagement and should be accounted for in the scope.
Number of subcontractors and trades
Main contractors carry the occupier’s duty, yet the audit examines how the SHMS reaches subcontractors on the ground. A site with many small subcontractors usually requires more interviews and more cross-checking of evidence than one with a few large ones.
Costs around the audit that quotes often separate
The audit visit is one component of the total spend. Four adjacent items are commonly scoped on their own, and the arrangement differs from one provider to another, so the point is to see them itemized rather than assume them.
| Cost item | What it covers | Why it matters |
|---|---|---|
| Audit preparation or gap assessment | A pre-audit review of the SHMS against the checklist elements | Identifies weak elements before the independent audit is scored |
| The audit cycle itself | Fieldwork by at least two auditors, report and scorecard, WSH eService submission | The recurring statutory cost, every six months for S$30 million or more sites |
| Corrective-action follow-up | Verification that findings have been closed | Prevents the same weaknesses from reappearing in the next cycle |
| Internal capability | Training of site safety staff on the checklist | Reduces dependence on outside support between cycles |
On the first row, a ConSASS gap assessment maps the elements to site evidence before filing. On the last, the ConSASS scoring system is worth understanding in detail because the scorecard is the document management uses to see where to direct resources. MOM describes it as a report card that tabulates results across the audited SHMS elements, allowing management to visualize maturity and allocate resources to strengthen weak areas.
A practical way to compare quotes is to ask each provider to state, in writing, which of these four items are included, how many days of fieldwork are assumed, and whether a re-visit to verify closure is charged. Quotes that look identical in headline price can differ by the full cost of the missing items.
A cost that is easy to miss: the SHARP route
Some contractors also pursue recognition. For the Safety and Health Award Recognition for Projects (SHARP), worksites need not engage an approved Auditing Organization if they use ConSASS results from October 2023 onwards with a total element score of at least 70% for Band III. In practice, a well-documented statutory ConSASS cycle can therefore serve a second purpose, which strengthens the case for treating the audit as an investment in the project’s safety record rather than a bare compliance expense.
How ConSASS cost differs from BizSAFE, ISO and Design for Safety
These services are often budgeted together, yet they behave differently.
- ConSASS is a recurring, project-specific audit of the worksite SHMS. The cost scales with the site and repeats every six months for qualifying projects.
- BizSAFE (Level 3, Level 4 and Star) is a company-level recognition. Its cost is tied to the organization’s readiness and the level pursued, not to a single worksite’s contract sum. See our BizSAFE Level 3, 4 and Star service.
- ISO certification concerns a management system certified by an independent body, with its own certification and surveillance structure. See our ISO certification service.
- Design for Safety is applied at design stage to remove hazards before construction. See our Design for Safety Professional service.
The distinction matters in the budget: ConSASS cannot substitute for the others, and none of them replaces ConSASS where the S$30 million threshold applies. For the boundaries, read ConSASS versus a general safety audit and ConSASS versus a WSH performance audit. Each service has no published price on our site, and scope-based quotations are provided after a consultation.
Controlling the total without lowering the standard
The most dependable savings come from reducing rework, not from reducing audit quality.
- Run a gap assessment two to three months before the first cycle. Weak Band I documentation is the cheapest category to correct.
- Keep one evidence register across the main contractor and subcontractors. Auditors then locate records in minutes rather than hours.
- Close findings before the next window. Open items carried between cycles create repeated discussion and repeated effort.
- Schedule fieldwork around active work fronts. The physical inspection and worker interviews are most valuable when representative activity is under way. Site logistics also matter: traffic management and plant movement affect how safely auditors walk the site, and a construction fleet visibility guide shows how vehicle warning lighting supports safer movement of construction vehicles.
- Train site personnel on the checklist. Familiarity with how interviews work lowers the volume of avoidable findings.
For a stepwise view of evidence building, our article on converting the checklist into site evidence and the one on preparing the ConSASS submission cover the process in detail.
Our perspective
Contractors tend to ask what the audit costs. We would argue that the sharper question is what an unprepared audit costs: the repeated cycles, the findings that carry forward, and the management time spent reconstructing records that should have existed from the first month of mobilization.
With more than 20 years of experience in quality, environment and safety consultancy, our position is that ConSASS is best treated as a management instrument, not a hurdle. The scorecard shows where the SHMS is mature and where it is not. A site that reads it that way directs resources to the weakest elements and arrives at the next cycle with evidence in place.
This is why our approach pairs audit-readiness with continuous support after the engagement, delivered by a multi-industry consultant team. Scope is tailored to the project, which is also why we quote after understanding the site rather than publishing a generic figure that would misstate the work.

FAQ
How much does a ConSASS audit cost in Singapore?
No official tariff exists, and fees are quoted per worksite by each auditing organization. The price depends on site scale, the audit team (at least two auditors), documentation readiness and the number of cycles. Request a quote per cycle and for the full project duration.
Who needs to pay for a ConSASS audit?
The occupier of a construction worksite with a contract sum of S$30 million or more must appoint an approved independent auditing organization at least once every six months. In practice, the main contractor carries that cost within the project budget.
Is preparation included in the audit fee?
That depends on how the provider scopes the engagement. Gap assessment, the audit cycle and corrective-action follow-up are frequently separate items, so confirm in writing which of them the quotation includes.
Is a ConSASS audit the same as BizSAFE or ISO certification?
No. ConSASS audits a specific worksite’s SHMS on a recurring cycle, while BizSAFE recognizes a company’s safety capability and ISO certifies a management system. Each is budgeted separately.
