In Italy, companies that want to work on public construction projects need a special certificate called SOA. It proves they are qualified and experienced enough to handle certain kinds of work.One of these categories is OS23 Demolition of Works antolohe. This category is about taking down buildings and structures safely and legally.I looked at the top websites that explain soa os23. Most of them agree on the main rules, but each one also adds some extra details. Below is a simple guide that brings everything together.
What soa os23 Means
Every website explains OS23 in the same way ,It covers:
Taking apart industrial plants
Complete demolition of buildings, even using explosives if needed
Cutting reinforced concrete with special tools
Handling and recycling waste materials after demolition
This is written in the law DPR 207/2010, Annex A. That law is the main reference for OS23.
Classes and Limits in soa os23
Each SOA category has classes. These classes show the maximum value of contracts a company can bid for. Here is the list:
| Class | Maximum Value |
|---|---|
| I | 258,000 |
| II | 516,000 |
| III | 1,033,000 |
| III bis | 1,500,000 |
| IV | 2,582,000 |
| IV bis | 3,500,000 |
| V | 5,165,000 |
| VI | 10,329,000 |
| VII | 15,494,000 |
| VIII | Over 15,494,000 |
For example, if a company has Class III, it can bid on demolition projects worth up to €1,033,000.
Is soa os23 Mandatory?
Some categories are mandatory or superspecialistic, which means they need special skills.
But for OS23:
Mandatory? No
Superspecialistic? No
This means companies do not have to get OS23 unless the tender says it is required. Still, having it can give a company more chances to win projects.
Environmental Part of OS23
All websites mention that OS23 also includes managing waste after demolition. This means:
Collecting materials
Separating waste
Recycling or reusing debris
This part is very important because European rules now push for more recycling and less waste. Companies with OS23 are expected to follow these standards.
Why soa os23 is Useful
Even if OS23 is not mandatory, having it can help companies because:
Shows they can handle big and complex demolitions
It proves legal and technical capacity
Helps win public contracts
It allows companies to join projects linked to green bonuses
Common Mistake: Mixing with Tech Term
Some search results for SOA OS23 are not about demolition at all. They are about software and IT systems. These are different and have nothing to do with Italian public works. Companies should ignore those when researching the certification.
