Nine Singapore Construction Sites Shut Down After Worker Deaths — What Triggers a Stop-Work Order and How to Avoid One

Price range: $$

In the second half of 2024, 14 construction workers died across 14 different worksites in Singapore — nearly triple the five fatalities recorded in the first half of the year. Of those 14 sites, nine were issued stop-work orders by the Ministry of Manpower for having inadequate safety management systems that posed imminent danger to workers.

A stop-work order is one of the most severe enforcement actions the Ministry of Manpower can take. It halts all work activities on a site until the safety deficiencies are rectified and independently verified. For construction companies, a stop-work order means project delays, liquidated damages, idle workers, damaged reputations, and — in some cases — debarment from future government projects.

The Incidents

The scale of the crisis in Singapore’s construction sector during the second half of 2024 was alarming. Senior Minister of State for Manpower Zaqy Mohamad confirmed in Parliament on 7 January 2025 that of the 14 worksites where construction fatalities occurred in H2 2024, nine were issued with stop-work orders due to inadequate safety management systems that posed imminent danger to their employees.

None of the 14 sites where fatal accidents occurred had previously been subjected to stop-work orders — meaning these were not known problem sites. The safety failures were systemic and went undetected until a worker died.

Overall, the construction sector recorded 20 workplace fatalities in 2024 — two more than in 2023 — making it the worst-hit sector. Across all industries, Singapore recorded 43 workplace deaths in 2024, up from 36 in 2023, according to the Ministry of Manpower’s Workplace Safety and Health Report 2024.

The Ministry of Manpower’s Response

The surge in construction fatalities prompted an unprecedented response from the Ministry of Manpower:

More than 3,000 inspections were conducted across the construction sector in 2024, focusing on working at height, vehicular safety, and struck-by-falling-objects incidents.
A two-week Safety Time-Out was ordered from 8 to 22 November 2024, requiring all construction firms to pause and refresh workplace safety and health practices.
New Video Surveillance System (VSS) regulations took effect on 1 June 2024, mandating the installation of video surveillance at construction sites with project values of $5 million and above.
Chief Executives and Board Directors in higher-risk sectors, including construction, are now required to attend the Top Executive Workplace Safety and Health Programme, strengthening accountability at the leadership level.
The Ministry of Manpower specifically flagged smaller firms involved in renovation work, maintenance, and facilities management as particularly problematic areas for safety compliance.

What Went Wrong

The Ministry of Manpower found that the nine sites receiving stop-work orders had inadequate safety management systems posing imminent danger to workers. While specific deficiencies varied by site, the common failures in Singapore construction safety include:

No functioning Safety Management System (SMS). An SMS is not just a binder on a shelf — it is a living system that identifies hazards, assesses risks, implements controls, monitors compliance, and corrects deficiencies. Many smaller contractors lack a properly implemented SMS.
Missing or inadequate risk assessments. Risk assessments for specific tasks — lifting operations, excavation, work at height, hot work — must be conducted before work begins and updated whenever conditions change. Generic, copy-and-paste risk assessments do not address site-specific hazards.
Absent or untrained safety personnel. The Workplace Safety and Health Act requires certain worksites to appoint a Workplace Safety and Health Officer or Coordinator. Some sites operated without qualified safety personnel entirely.
Failure to implement Safe Work Procedures (SWPs). Each high-risk activity needs documented Safe Work Procedures that workers are trained on, understand, and follow. When SWPs exist on paper but are not implemented on the ground, they provide zero protection.
Inadequate supervision of sub-contractors. Main contractors are responsible for the safety of everyone on their site — including sub-contractors’ workers. When supervision is lax, safety standards erode rapidly.

The Cost of a Stop-Work Order

A stop-work order is not just a temporary inconvenience. Its consequences cascade across every aspect of a construction business:

Project delays. All work activities must cease until the Ministry of Manpower is satisfied that safety deficiencies have been rectified. This can take weeks or months. For time-sensitive projects, delays trigger liquidated damages — contractual penalties that can amount to thousands of dollars per day.
External safety audit costs. Before work can resume, sites with serious lapses must undergo an external safety audit by an independent auditor. This costs money and takes time.
Idle workforce costs. Workers who cannot work still need to be housed, fed, and paid (or redeployed, which has its own costs). For companies with large foreign workforces on work permits, the financial burden is significant.
Increased fines. Since 1 June 2024, the maximum fine for safety breaches resulting in death increased to SGD $50,000 per charge. Employers face fines of up to SGD $500,000 and imprisonment of up to 2 years.
Demerit points. Under the Ministry of Manpower’s demerit point system for construction, a partial stop-work order results in 5 demerit points, while a full stop-work order results in 10 demerit points. Each demerit point is valid for 18 months.
Debarment risk. Companies with poor safety records — including stop-work orders — risk being debarred from government construction tenders. For firms that depend on public-sector projects, this is an existential threat.
Insurance premium increases. A stop-work order on your record triggers insurance premium increases and may make it harder to obtain project insurance in the future.
Reputational damage. Stop-work orders are public information. Developers, clients, and partner firms check safety records before awarding contracts.

What Triggers a Stop-Work Order From the Ministry of Manpower?

Understanding what triggers a stop-work order is the first step to avoiding one. The Ministry of Manpower issues stop-work orders when:

A workplace fatality or serious injury has occurred and the investigation reveals systemic safety failures.
An inspection reveals conditions that pose imminent danger to workers — meaning a serious injury or death could occur at any time.
The worksite’s Safety Management System is found to be grossly inadequate for the type and scale of work being performed.
Previous enforcement actions (warnings, composition fines, improvement notices) have not resulted in compliance.

Lessons Learned: Avoiding a Stop-Work Order

The following recommendations are general industry best practices for educational purposes only. Every workplace is different — consult a qualified safety professional before implementing changes specific to your situation.

Build and maintain a real Safety Management System. Not a shelf document — a living, implemented system with clear responsibilities, regular reviews, and documented evidence of compliance.
Conduct site-specific risk assessments for every task. Generic risk assessments are not sufficient. Each task, each site, and each set of conditions requires its own assessment.
Appoint qualified safety personnel — and empower them. Your Workplace Safety and Health Officer or Coordinator must have the authority to stop unsafe work, the resources to implement safety measures, and the backing of management.
Audit your sub-contractors’ safety practices. As the main contractor, you are legally responsible. Verify that sub-contractors have trained workers, valid permits, and compliant equipment.
Conduct internal safety audits before the Ministry of Manpower does. Regular self-audits — weekly walk-throughs, monthly system reviews, quarterly audits — identify issues while they can still be fixed without enforcement action.
Respond immediately to any Ministry of Manpower feedback. If you receive a warning, improvement notice, or composition fine — treat it as an urgent priority. The alternative is a stop-work order.

Recommended Best Practices

Industry best practices for construction safety and stop-work order prevention go beyond minimum regulatory compliance. Organisations committed to protecting their workers and avoiding enforcement action should consider the following:

Stop-work order rectification — If your site has already received a stop-work order, respond immediately. Assess the deficiencies, develop a rectification plan, implement the required measures, and prepare the documentation needed for the Ministry of Manpower to lift the order.
Annex A response — If your site has received a Ministry of Manpower Annex A notice following an accident investigation, address every item methodically within the specified timeframe and submit evidence of compliance.
Safety audits — Conduct regular audits of your Safety Management System against the Workplace Safety and Health Act requirements and Code of Practice. Identify gaps, prioritise corrective actions, and create a clear roadmap to compliance.
Risk assessments — Conduct comprehensive, site-specific risk assessments for all construction activities — including lifting operations, excavation, work at height, confined space entry, and hot work.
Safety personnel provision — Ensure a qualified Workplace Safety and Health Officer or Coordinator is available for your site on a full-time, part-time, or project basis.

Frequently Asked Questions

How long does a stop-work order last in Singapore?

There is no fixed duration for a stop-work order. The order remains in force until the Ministry of Manpower is satisfied that the safety deficiencies have been rectified. This can take anywhere from a few days to several months, depending on the severity of the deficiencies and the complexity of the rectification measures required. Sites with serious lapses may need to undergo an external safety audit before the order is lifted.

What is a Ministry of Manpower Annex A notice?

An Annex A notice is issued by the Ministry of Manpower following a workplace accident investigation. It lists the specific safety deficiencies found at the worksite and the corrective actions required. The company must address every item in the Annex A within the specified timeframe and submit evidence of compliance. Failure to comply can result in further enforcement action, including prosecution. Annex A response requires methodical documentation and expert safety knowledge.

Can a company be debarred from government tenders for safety violations?

Yes. Companies with poor workplace safety and health records — including those that have received stop-work orders, been prosecuted for safety offences, or have a high accident rate — may be debarred from bidding on government construction and facilities management tenders. Singapore’s public sector takes safety records seriously when evaluating tender submissions, and debarment can last for years.

What is the difference between a stop-work order and a Safety Time-Out?

A stop-work order is a legal enforcement action issued by the Ministry of Manpower to a specific worksite, requiring all work to cease until safety deficiencies are rectified. Failure to comply is a criminal offence. A Safety Time-Out, on the other hand, is a broader industry-wide initiative where the Ministry of Manpower requests all companies in a sector (such as construction) to voluntarily pause work and review their safety practices. The November 2024 Safety Time-Out covered the entire construction sector for two weeks.
