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.
The standard SRPS EN 13670:2012 (Execution of concrete structures) is the Serbian adoption of the European standard EN 13670:2009
, providing essential requirements for the construction of concrete structures.
Институт за стандардизацију Србије Scope and Application This standard applies to both permanent and temporary concrete structures , covering:
Институт за стандардизацију Србије In-situ works : Concrete cast directly on-site. Prefabricated elements
: Construction using precast concrete parts (though it does not cover the production srps en 13670
of these elements, which is handled by product-specific standards).

SRPS EN 13670 is the official Serbian adoption of the European standard for the execution of concrete structures
, providing the fundamental "rules of the game" for building anything from a simple house foundation to a massive bridge.

While a technical standard might seem dry, its "story" is one of safety and the invisible backbone of our modern world. The Life of a Concrete Structure (A Story of SRPS EN 13670)
Imagine a massive construction project—a new bridge over the Danube. Without SRPS EN 13670 Marko stood on the edge of the sprawling
, that bridge is just a pile of ingredients and hope. Here is how the standard "tells" the story of that structure: The Foundation of Rules
: Before the first truck arrives, the standard establishes the Execution Specification
. This is the blueprint for quality, ensuring that the design on paper can actually be built safely in the real world. The "90-Minute" Race
: Once the concrete is mixed, a invisible clock starts. Standards like this help govern the logistics, such as the 90-minute rule
—the critical window to get concrete from the truck into the forms before it loses its workability. The Growing Pains
: Concrete is "alive" in its first few weeks. It typically reaches about 70% of its strength
in the first 7 days, but requires a full 28 days to reach its design potential. SRPS EN 13670 ensures that during this vulnerable time, the structure is protected and cured correctly. The Thousand-Year Hope
: While modern concrete is built to last decades, engineers look to ancient Roman concrete
for inspiration—some of which has survived over 2,000 years. By following the rigorous checks in SRPS EN 13670, today's engineers aim to create that same legacy of durability.
Институт за стандардизацију Србије Key Facts About the Standard : It covers both (poured on-site) and prefabricated concrete works.
: The Serbian version was officially published in its latest form in September 2024 Institute for Standardization of Serbia (ISS)
: It ensures that no matter who the contractor is, they must meet the same high bar for safety and structural integrity.
SRPS EN 13670: The Standard for Execution of Concrete Structures
SRPS EN 13670 is the official Serbian adoption of the European standard EN 13670:2009, which establishes common requirements for the execution of concrete structures. In Serbia, this standard is managed by the Institute for Standardization of Serbia (ISS) and serves as a critical bridge between structural design (governed by Eurocodes like SRPS EN 1992) and the actual construction process. Scope and Applicability
The standard is designed to ensure that the intended safety and serviceability of a structure are achieved during its construction. It applies to:
In-situ works: Concrete poured directly on the construction site. EN 1992 tells you what strength and dimensions
Prefabricated elements: The installation and assembly of precast concrete elements.
Permanent and temporary structures: It covers both long-term buildings and temporary construction aids.
It does not cover the production of concrete itself (which is covered by SRPS EN 206) or the health and safety aspects of the construction site. Key Technical Requirements
SRPS EN 13670 organizes construction requirements into several core technical areas to maintain quality and structural integrity:
Execution Management: Requires clear documentation, including an execution specification and a quality plan. It defines Execution Classes (1, 2, or 3) based on the importance and complexity of the structure.
Falsework and Formwork: Sets standards for the design and removal of temporary supports to ensure they can carry loads during the curing process.
Reinforcement and Prestressing: Provides strict guidelines on the handling, bending, and placement of steel reinforcement and the tensioning of prestressed tendons.
Concreting Operations: Covers everything from the delivery and placement of concrete to compaction and curing, which is vital for preventing cracks and ensuring strength.
Geometric Tolerances: Defines the allowable deviations in the final dimensions of the structure to ensure it matches the original design intent. Implementation in Serbia SRPS EN 13670:2012
Here’s a useful breakdown of SRPS EN 13670 — the Serbian standard that adopts the European EN 13670:
The standard requires a named person responsible for all execution activities. This is typically the site manager, but they must have authority to stop work if non-compliant.
Many professionals confuse this standard with Eurocode 2 (SRPS EN 1992), which covers the design of concrete structures. Think of it this way:
A major shift introduced by SRPS EN 13670 is the requirement for a formal Execution File. This is not just a set of drawings but a comprehensive quality management document.
The Execution File must include:
This file must be available on site before concrete placement begins. Without it, inspectors and technical control bodies can legally halt the work.
