SOA OS23 Guide: Certification & Architecture Explained

The term SOA OS23 can be confusing because it has two very different meanings. In Italy’s construction sector, it refers to the SOA OS23 certification, a qualification required for companies bidding on public works tenders in the demolition of works category.

At the same time, in the technology world, SOA OS23 is seen as Service-Oriented Architecture 2023, a modern standard for building flexible, modular, and secure systems. This guide covers both perspectives, helping contractors, IT professionals, and business leaders understand why SOA OS23 matters today and how it impacts their field.

What is SOA OS23?

SOA OS23 has two recognized contexts.

In construction, it is a specialized SOA certification in Italy that covers the demolition of works. Companies must hold the OS23 category to qualify for large public works tenders, proving they have the technical skills, financial strength, and compliance documents like CEL and DURC. Without it, they cannot legally participate in demolition projects.

In IT and software, SOA OS23 is short for Service-Oriented Architecture 2023, a modern approach to designing systems with modular, scalable, and secure components. Unlike older SOA models, OS23 emphasizes interoperability and cloud integration, making it attractive for industries like finance, healthcare, logistics, and government services.

SOA OS23 in Construction (Certification for Demolition Works)

In Italy, the SOA OS23 certification is essential for companies that want to carry out demolition works within public works tenders. This certification is part of the broader Attestazione SOA system, which regulates access to government contracts above €150,000. Holding the OS23 category proves that a contractor has the required technical capacity, financial stability, and organizational strength to manage demolition safely and responsibly.

The legal foundation comes from ANAC regulations, which ensure only qualified firms are awarded projects. Without this certification, even experienced contractors cannot bid on significant demolition jobs. For construction businesses, achieving SOA OS23 isn’t just about compliance — it’s about credibility, competitiveness, and opening doors to larger, more profitable public sector opportunities.

Requirements for SOA OS23 Certification

To obtain the SOA OS23 certification, demolition companies must meet strict standards set by ANAC. These requirements are designed to guarantee that only qualified businesses can access public works tenders in the OS23 category.

• Technical capacity – Contractors must provide CEL (Certificates of Executed Works) to prove successful demolition projects in the past.
  
• Economic and financial stability – Evidence of turnover, balance sheets, and financial health is required to show long-term reliability.
  
• Organizational resources – Companies need qualified staff, safety procedures, and proper equipment for demolition works.
  
• Compliance documents – A valid DURC (Documento Unico di Regolarità Contributiva) is essential to prove social security and tax compliance.
  

Meeting these conditions ensures that a company is not only eligible for SOA OS23 certification but also trusted to handle complex demolition projects safely and effectively.

SOA OS23 Classes (I–VIII)

The SOA OS23 certification is divided into eight classes, each linked to the maximum contract value a company can bid for in public works tenders. This system ensures that demolition firms compete fairly, based on proven financial and technical capacity.

Selecting the right OS23 category class depends on turnover, documentation, and certified experience. A higher class means access to bigger projects, but also stricter requirements.

Step-by-Step Process to Get SOA OS23

Applying for the SOA OS23 certification requires careful planning. Here’s how demolition companies can secure their OS23 category for public works tenders:

1. Prepare documentation – Collect CEL certificates, financial statements, and a valid DURC to ensure public works tender compliance and demonstrate readiness for SOA OS23 certification.
   
2. Select a certifying body – Only accredited SOA agencies authorized by ANAC can issue the certificate.
   
3. Submit the application – Provide all technical, financial, and organizational records for review.
   
4. Verification and checks – The agency evaluates whether the company meets OS23 requirements, including eligibility for specific classes (I–VIII).
   
5. Certification issuance – If approved, the Attestazione SOA OS23 is granted, valid for five years, with a three-year compliance check.
   
6. Renewal – Before expiration, companies must reapply with updated documents to maintain eligibility.
   

Following these steps ensures a smooth process, reduces delays, and keeps contractors fully compliant for Italy’s demolition tenders.

Costs and Timeframes of SOA OS23

The cost of obtaining SOA OS23 certification varies depending on the chosen class (I–VIII) and the size of the company. Smaller firms applying for lower OS23 categories (Class I or II) face lower expenses, while higher classes such as VII or VIII involve greater costs due to the value of contracts allowed. Fees typically include application charges, verification costs, and, in some cases, consultant support.

In terms of timing, the process usually takes 2 to 4 months, depending on how quickly documents like CEL and DURC are prepared and verified. Once approved, the certification remains valid for five years, but contractors must undergo a three-year compliance check to confirm continued eligibility. Renewal is generally faster and less costly than the initial application, but it still requires updated financial and organizational proof.

SOA OS23 in IT and Software Architecture

Beyond the construction sector, SOA OS23 is also recognized in the technology world as Service-Oriented Architecture 2023. This modern framework builds on the original SOA concept but adapts it to today’s digital needs. The goal is to design modular, scalable, and secure systems that allow services to work together seamlessly.

Unlike older SOA models, SOA OS23 focuses heavily on cloud solutions for compliance tracking, interoperability, and automation.. It provides a structure where different applications — whether in finance, healthcare, logistics, or government services — can communicate without rigid dependencies. This makes businesses more agile, reduces integration costs, and supports rapid innovation.

In short, SOA OS23 for IT represents the evolution of service-oriented architecture, aligning with trends like APIs, microservices, and digital transformation while still emphasizing governance and compliance. For organizations, adopting SOA OS23 means building systems that are future-ready and easier to scale.

Use Cases of SOA OS23 in IT

The SOA OS23 (Service-Oriented Architecture 2023) model is widely used across industries that rely on flexibility, data sharing, and secure integration. Some key examples include:

• Finance – Banks and payment platforms use SOA OS23 to connect core banking systems with mobile apps, ensuring real-time transactions and regulatory compliance.
  
• Healthcare – Hospitals and clinics adopt SOA OS23 for EHR (Electronic Health Record) integration, enabling patient data to flow safely between departments and external systems.
  
• Logistics and supply chain – Transport companies apply SOA OS23 to track shipments, optimize routes, and coordinate with global partners in real time.
