SRPS EN 13670 standard, titled "Execution of concrete structures"
, provides common requirements for the practical construction of concrete structures to ensure they meet the design intent for safety and durability. Scope and Application Standard Coverage : Applies to both in-situ concrete work and construction using prefabricated (precast) concrete elements Structure Types : Applicable to both concrete structures. Connection to Design
: It is specifically designed to complement Eurocode standards, such as SRPS EN 1992 (Design of concrete structures). Key Technical Requirements
The standard organizes execution requirements into several critical technical areas: Execution Management : Requires the development of a Quality Plan
, execution records, and documentation of any special procedures. Formwork and Falsework
: Covers the design, installation, and removal of temporary supports, including the use of release agents. Reinforcement
: Specifies technical requirements for the handling, bending, and installation of reinforcing steel. Concreting Operations
: Provides guidelines for the placing, compacting, and curing of concrete to ensure the material reaches its intended strength. Inspection Regimes : Establishes Execution Classes
that dictate the level of inspection and quality control required based on the importance of the structure.

Marko stood on the edge of the sprawling Belgrade construction site, the wind whipping dust across the fresh excavations. As the lead engineer for the "Sava Heights" project, the weight of the sixteen-story residential tower rested on his shoulders. In his hand, he held a worn copy of SRPS EN 13670.
To the uninitiated, it was a dry document of technical requirements. To Marko, it was the law.
“We’re ready to pour the first section of the basement raft,” shouted Jovan, the site foreman, over the drone of a nearby generator. “The trucks are lined up.”
Marko didn’t nod immediately. He walked to the massive grid of reinforcement steel. According to Section 6 of the standard, he had to verify the "Execution of Reinforcement." He checked the spacing of the bars and the concrete cover—the vital layer of protection that prevents steel from rusting.
“The cover blocks are too sparse in the south corner, Jovan,” Marko said, pointing. “If that steel shifts during the pour, we lose durability. We follow the standard, or we don't pour.”
Jovan sighed but signaled the crew to add more supports. He knew Marko was right. SRPS EN 13670 wasn't just about making the building stand; it was about making it last for fifty years without crumbling.
As the sun began to set, the first concrete pump roared to life. This was the "Execution" phase—Section 8. Marko watched the slump test, ensuring the concrete mix had the right consistency. He checked the vibration crew; if they vibrated the concrete too little, there would be air pockets (honeycombing); too much, and the heavy stones would sink to the bottom.
Hours later, the slab was finished, a smooth gray lake under the site lights. But Marko’s job wasn't done. “Start the curing immediately,” he instructed.
“It’s a cool night,” Jovan argued. “It won’t dry too fast.”
“Section 8.5,” Marko replied firmly. “We protect the surface from drying out to prevent cracks. Cover it with hessian and start the misting.”
Weeks later, the laboratory results came back. The compressive strength was perfect. The geometry was within the strict tolerances of Annex B. Because they had respected the "Execution of Concrete Structures," the tower wasn't just a heap of stone and metal—it was a monument to precision.
Marko looked up at the rising skeleton of the building, knowing that every pillar and beam followed the silent rhythm of the standard. He wasn't just building a house; he was building a guarantee.
A key feature of SRPS EN 13670 (the Serbian national adoption of the European standard EN 13670) is its focus on "Execution Classes,"
which allow for a tailored approach to quality management based on the complexity and risk of a specific project. iTeh Standards Why Execution Classes Are Important
Instead of a "one-size-fits-all" rule, this standard uses three Execution Classes to determine the level of inspection and documentation required: iTeh Standards Execution Class 1:
Used for simple, low-risk structures (e.g., small agricultural buildings or single-story structures) where minimal oversight is needed. Execution Class 2: Key point regarding "piece": If you need the
The "default" class for most standard engineering projects, such as residential or commercial buildings. Execution Class 3:
Reserved for complex, high-risk structures (e.g., high-rise buildings or major bridges) that require the most stringent quality controls and documentation. Other Notable Components
The standard acts as a bridge between the design (Eurocode 2) and the final structure, ensuring that the safety assumptions made during design are actually met on-site. It covers: iTeh Standards Falsework and Formwork:
Detailed requirements for design and removal to prevent premature structural stress. Concreting Operations: Specific protocols for delivery, placing, compaction, and —which is vital for durability. Geometrical Tolerances:
Provides clear limits on deviations for foundations, walls, and beams to ensure everything fits as designed. iTeh Standards You can find more specific technical details on the Institute for Standardization of Serbia (ISS) project page.

SRPS EN 13670 specifies the requirements for the execution of concrete structures. Regarding preparation, the standard emphasizes that the surface must be treated to ensure proper bond strength between the existing substrate and new concrete (or other materials). This is critical for structural integrity and durability.
The standard defines three levels of inspection:
An independent body verifies compliance. This is mandatory for high-risk structures.
For each concreting operation, a pre-concreting inspection must be signed off, covering:
| Mistake | Consequence | SRPS EN 13670 Solution | |---------|-------------|------------------------| | No execution class defined | Quality control too strict or too lax | Specify EXC in project documents | | Using only design drawings for construction | Missing reinforcement details | Prepare execution drawings | | No pre-concreting checklist | Placing concrete over contaminated formwork | Use standard inspection form (Annex A) | | Striking formwork too early | Major cracks or collapse | Measure actual concrete strength | | No curing records | Surface cracks, low durability | Log start/end dates and method |

This is the heart of the execution process. SRPS EN 13670 dictates:
