In Italy, public construction and demolition projects follow strict regulations to ensure safety and transparency. To qualify for public tenders above €150,000, companies must hold official certifications. Among these, the SOA OS23 certification is essential for demolition and specialized dismantling works.
This qualification demonstrates a company’s technical expertise, financial reliability, and compliance with environmental and safety standards. In this article, we’ll explore what SOA OS23 is, why it matters, and how businesses can obtain it.
What Is SOA Certification?
SOA certification (Società Organismo di Attestazione) is mandatory for contractors in Italy who wish to participate in medium-to-large public works. It validates a company’s ability to meet technical, legal, and financial obligations.
SOA is divided into:
- General categories (OG), covering broad construction works.
- Specialized categories (OS), focusing on specific trades.
Within these, OS23 is the category dedicated to demolition works.
Understanding the OS23 Category
The OS23 qualification ensures that companies are capable of performing safe and efficient demolition, whether partial dismantling or complete removal of civil and industrial structures.
Typical activities include:
- Controlled demolition of buildings.
- Dismantling steel or reinforced concrete frames.
- Safe debris handling and waste disposal.
- Use of mechanical, hydraulic, or explosive techniques when needed.
By holding SOA OS23, a company shows it can manage high-risk demolition with professionalism.
Why SOA OS23 Matters in Public Works
Public authorities in Italy rely on certified companies to reduce risk in demolition projects. SOA OS23 matters because it:
- Provides legal authorization for bidding on specialized demolition contracts.
- Demonstrates compliance with Italian safety laws.
- Builds trust with clients and institutions.
- Enhances competitiveness in a crowded construction market.
Without this certification, even highly skilled demolition firms cannot access lucrative public tenders.
Requirements for SOA OS23 Certification
To qualify, companies must meet rigorous criteria across several areas.
Technical and Professional Capacity
- Proven record of past demolition projects.
- Skilled engineers and staff with relevant training.
- Access to specialized demolition equipment.
Financial and Organizational Capacity
- Solid financial statements covering the last five years.
- Adequate turnover matching the requested class of certification.
- Clear organizational structure capable of handling contracts responsibly.
Legal and Safety Standards
- Compliance with tax and social security contributions.
- Adherence to health and safety legislation.
- Demonstrated environmental responsibility in waste management.
Scope of Work Covered by OS23
The OS23 category covers a broad range of demolition services, such as:
- Total demolition of buildings and industrial facilities.
- Partial dismantling of bridges, towers, or large components.
- Controlled demolition with explosives or specialized machinery.
- Site clearance, debris transport, and recycling of materials.
In short, SOA OS23 ensures a company is prepared for every phase of demolition, from planning to waste recovery.
Classes of OS23 and Contract Values
OS23 certification is divided into classes that define the maximum contract value a firm can bid for:
- Class I: up to ~€258,000
- Class II: up to ~€516,000
- Class III: up to ~€1,033,000
- Class IV: up to ~€2,582,000
- Class V: up to ~€5,165,000
- Class VI and higher: progressively larger values
Advancing to higher classes requires stronger financial and technical evidence.
Application Process for Certification
The path to obtaining SOA OS23 involves several steps:
- Pre-assessment – collect technical, legal, and financial documents.
- Submission – apply to an accredited certification body.
- Verification – auditors evaluate past projects, accounts, and compliance.
- Approval – certificate granted if requirements are met.
- Validity – lasts five years, with a check after three years.
This thorough review ensures only reliable firms achieve OS23 status.
Benefits of Obtaining SOA OS23
Certification offers significant advantages:
- Eligibility to participate in demolition tenders.
- Proof of technical competence and reliability.
- Improved industry reputation.
- Access to larger projects through higher classes.
- Competitive edge in both public and private markets.
Challenges in Achieving OS23
Despite the benefits, the road to certification isn’t easy:
- Extensive documentation and audits.
- High costs for certification and compliance upgrades.
- Strict safety and environmental standards.
- Need to maintain performance for renewals.
These challenges, however, ensure that OS23 remains a mark of quality.
Trends and Future Outlook
The demolition sector is evolving, and so is the role of OS23. Key trends include:
- Green demolition: recycling and sustainable disposal of waste.
- Digital tools: use of BIM and GIS for planning safe dismantling.
- Stricter regulations: ongoing updates to safety laws.
- Eco-friendly procurement: preference for certified sustainable practices.
Firms aligning their SOA OS23 compliance with these trends will lead the market.
Conclusion
The SOA OS23 certification is far more than a bureaucratic formality—it is a passport to Italy’s demolition and specialized works sector. By meeting strict requirements in technical expertise, finances, and compliance, companies prove they are trustworthy partners for complex projects.
For demolition contractors, pursuing OS23 means credibility, opportunity, and long-term growth in Italy’s competitive public works market.
