Why is the EN 1090-2 (EXC3) Standard Mandatory for Large-Scale Construction Projects in Latvia?

The modern construction industry in Latvia is experiencing rapid development. When planning large-scale infrastructure projects—from shopping centers and factories to bridges and overpasses—the choice of metal structures is a critical point that demands not only fast execution but also uncompromising safety.

Latvian and European legislation (EU CPR) clearly state: if a facility involves a high flow of people or high structural loads, EXC3 metal structures are required. In this article, we will explain why the EN 1090 certificate in the Latvian market is no longer just a bureaucratic formality or an "optional paper," but a mandatory requirement and the gold standard of the industry.

What is EN 1090-2 and Execution Class EXC3?

The EN 1090-2 standard defines the technical requirements for the manufacturing of steel structures, dividing them into four Execution Classes (EXC), depending on the complexity of the structure and the risk of failure:

• EXC1 & EXC2: Designed for simple buildings with a lower risk level (e.g., private houses or small warehouses).
• EXC3: A mandatory requirement for complex structures, such as public buildings, stadiums, bridges, and structures subjected to dynamic loads. In large state and commercial procurements (e.g., the construction of Rail Baltica stations), this class is strictly required.
• EXC4: Extreme-risk facilities (e.g., nuclear power plants).

The EXC3 level guarantees complete material traceability, specific welder certification, and extremely strict Factory Production Control (FPC).

The Absence of CE Marking: Massive Risks for the General Contractor

The European Union Construction Products Regulation strictly dictates that all load-bearing steel structures placed on the market in EU member states must have a CE marking. Without an EN 1090 certificate, the manufacturer has no legal right to apply this mark.

What are the consequences for the general contractor if non-compliant structures are used?

• Commissioning problems: The Construction Board and supervisory authorities can refuse to accept the facility if there are no corresponding CE declarations, causing project downtime.
• Insurance denial: In the event of an accident or defect, insurers will refuse compensation because the structures are not certified according to legislation.
• Full legal liability: The general contractor assumes colossal financial and criminal risks for safety compromised by low-quality load-bearing elements.

Frequently Asked Questions (FAQ)

1. Why is the EN 1090-2 (EXC3) standard mandatory for large-scale construction projects in Latvia? Safety is paramount in modern infrastructure. EU regulations (CPR) mandate EXC3 execution class for structures with high occupancy or dynamic loads, such as bridges, stadiums, and large commercial hubs. This standard ensures total material traceability and rigorous manufacturing quality control.

2. What are the risks of using steel structures without a CE marking? Without CE marking (backed by EN 1090 certification), building authorities may halt commissioning, insurers can deny claims in case of defects, and the general contractor assumes full legal and criminal liability for the structural integrity of the project.

3. Why partner with "Promstal GTU"? We are a Riga-based manufacturer certified under EN 1090-1 (up to EXC3 class). We offer a complete technical documentation package, CE declarations, and efficient Baltic-wide logistics, ensuring that your large-scale projects meet all European safety standards without delays.
