With effect from 1 August 2011, all construction worksites with a contract sum of S$30 million or more are required to have their mandatory SHMS audits conducted based on the Construction Safety Audit Scoring System (ConSASS) checklist.
Regulation 9 of Workplace Safety and Health (Safety and Health Management System and Auditing) regulations 2009 states that it shall be the duty of the occupier of a construction worksite to appoint a workplace safety and health auditor to audit the safety and health management system of the workplace at least once every 6 months.
Quality Safe provides professional ConSASS audit services for construction worksites across Singapore. Our construction safety audit is carried out by accredited, experienced auditors to help your worksite achieve and maintain full regulatory compliance.
The Construction Safety Audit Scoring System is a structured audit tool for assessing the Safety and Health Management System (SHMS) at a construction worksite. It measures the maturity and real-world effectiveness of your safety protocols across 20 SHMS elements, validating what is documented while verifying that these standards are genuinely implemented on-site.
The three-band scoring framework gives management a clear maturity profile of each system element, so resources can be directed where they are needed most and your worksite stays aligned with industry best practices.
The construction safety audit also enables cross-comparison between worksites, helping developers and clients assess how well contractors manage workplace safety and health risks before awarding contracts.
A ConSASS audit is a mandatory regulatory requirement for occupiers of construction worksites with a contract sum of S$30 million or more.
Once the threshold is met, the first construction safety audit must be completed within two months of the worksite’s registration. Thereafter, audits must be conducted at least once every six months to maintain ongoing regulatory compliance.
A ConSASS audit evaluates a construction worksite’s Safety and Health Management System against the requirements of the WSH Act and its subsidiary legislation, SS ISO 45001:2018 Occupational Health and Safety Management Systems, and the ConSASS audit checklist. The checklist covers 20 SHMS elements structured along the Plan-Do-Check-Act (PDCA) cycle, from WSH policy and risk management through to incident investigation and continual improvement.
During the construction safety audit, the auditing team reviews and assesses the following:
Upon completion, the ConSASS audit produces a maturity profile for each of the 20 SHMS elements across a three-band scoring framework. This gives management a clear, structured view of where the system is performing well and which areas require targeted improvement.
For worksites seeking to align their SHMS with international standards, our ISO 45001 safety management system consulting services provide the foundation needed to achieve and sustain certification.
Quality Safe brings together the accreditations, hands-on experience, and full-spectrum WSH capability that construction worksites need to approach a ConSASS audit with confidence.
The current ConSASS audit checklist covers 20 Safety and Health Management System elements:
A construction safety audit is an independent assessment of a worksite's Safety and Health Management System to verify that WSH controls are documented, implemented, and effective.
ConSASS stands for Construction Safety Audit Scoring System. It is the mandatory SHMS audit framework for Singapore construction worksites with a contract sum of S$30 million or more.
A ConSASS audit identifies gaps in your SHMS, profiles the maturity of each system element, and helps management prioritize improvements to strengthen overall worksite safety performance.
Qualifying construction worksites must conduct a ConSASS audit at least once every six months, with the first audit completed within two months of worksite registration.
After the ConSass audit, Quality Safe prepares a formal report outlining all findings and monitors the closure of action items to ensure corrective measures are fully and properly implemented.
