BIM in Fire Safety at Coca-Cola HBC: FineFIRE Case Study


This article aims to highlight the practical benefits of using BIM software for fire protection design through a real-world case study involving the storage capacity expansion of a bottling plant of Coca-Cola HBC S/E Europe in Timis, Romania.

The specific project has to do with a sprinkler installation applied to a new storage space of Coca-Cola HBC, occupying a total storage area of 30.000 sq ft plus a loading area of 13.000 sq ft, using a ceiling sprinkler system along with a sprinkler system in-rack. The project was completed in January 2019.

The firefighting network has been designed and calculated with FineFIRE, a BIM vertical belonging to the FineMEP Suite. FineFIRE combines an AutoCAD-like functionality with a familiar BIM approach that helps its user locate the sprinklers and draw the piping network quickly and intelligently. The smart modeling component works with the calculation engine of FineFIRE to simulate the fire installation precisely in order to provide the pipe sizing details and pump specifications at construction detail level.

Why BIM and FineFIRE

Building Information Modeling (BIM) is an intelligent 3D model-based process using semantic information to simulate the building model behavior in order to assist the designer to reach the optimum alternatives. When it comes to Fire Protection systems, a BIM software tool considers all the parameters of the physical and functional characteristics of a sprinkler network to support a series of tasks, such as smart network modeling, the identification of clashes with the other MEP installations, quick exploration of alternative viable options, extraction of the bill of materials, and many others. All these functionalities, in conjunction with the easy collaboration and sharing of information between the designer and the constructor, provide the designer with more time to focus on the higher-level aspects of the design and therefore to aim at the best alternative.

Even though the above principles and concepts are more or less present in other BIM software products as well, we are referring to FineFIRE below since it was the specific BIM tool selected for the respective case study. There are some important reasons why FineFIRE was selected by the designers:

  • It combines a state-of-the-art BIM technology plus an AutoCAD-like look and feel in order to help the user design the piping networks faster and easier.

  • It ensures full compatibility with Revit®, Archicad®, Vectorworks®, SketchUp Pro® or equivalent, through the IFC2x3 format.

  • It guarantees reliable and fully documented hydraulic calculations according to all the widely known standards like NFPA 13 (American Standard), EN 12845 (European Standard), BS 9251 (British Standard), AS 2118 (Australian Standard), ASIB11 (South Africa Standard), FM GLOBAL, CEA 4001, and others.

  • It allows design of any type of piping network (tree systems, gridded, looped or any combination).

  • It places the sprinklers automatically in each space in accordance with the building hazard (LH, OH, HH) and the type of sprinkler (roof, sidewall sprinkler or both).

  • It specifies (through a detailed hydraulic simulation) the most favorable and unfavorable sprinkler groups and selects the appropriate pump by considering the operation curves/diagrams, the NPSH point, and all other factors.

  • It generates the exact quantity of the materials that need to be used in the project (i.e., pipes, number of sprinklers, fittings, etc.).

  • It provides a fully documented final printout consisting of the calculation report with the intermediate and final results, and a complete set of drawings in 2D and 3D as specified by the standards.

  • All of the above coexist synergistically within an integrated BIM environment where the user can work and interact directly on the 3D building model.

Network Design

The relevant storage use determines the hazard classification according to the NFPA 13 standard. In this case study, ordinary hazard sprinklers (OH) were placed, while the storage space was divided accordingly into areas to place ceiling or sidewall sprinkler grids automatically. FineFIRE saves considerable time by proposing the optimal number of sprinklers in the grid of each area. By applying the command “array of sprinklers,” the program correctly places the sprinkler heads, keeping the proper distances among the sprinklers themselves and the wall boundaries. Such an automated network modeling process achieves great time savings, a factor which is quite critical for medium and large-scale projects such as in our project where 1.700 sprinklers had to be placed (Figure 2).

In addition to the sprinkler location, the resultant piping design is also simplified through the FineFIRE routing commands, which support the placement of any type of network (branches, sub-branches, grids, and loops) regarding the main pipes, as well as the network pipe connections between the sprinklers and main pipes, which are performed automatically for each group of sprinklers as defined by the user (Figure 3).

In this specific case study, sprinklers were grouped in 88 groups, each one of which was assigned to cover a specific area. What is important at this stage is the network recognition process by FineFIRE, which checks the validity of the network by indicating possible mistakes and how they should be corrected. Thanks to this algorithm, the continuity and rationality of the network — which comprised over 3.600 nodes for this case study — is ensured before the hydraulic calculations take place. 

With the use of FineFIRE, the numbering of the network nodes, network section lengths, sprinkler heads and piping fittings are all transferred properly to the calculation sheet for further analysis.


Calculation results, as provided by the FineFIRE calculation engine, specify the detailed dimensioning of the project network where each pipe is sized in compliance with the standards. Node numbers and segments are numbered and named automatically to provide visibility and easy control in the calculation sheet for every pipe segment and sprinkler (Figure 5).

Parameters like maximum area of operation per sprinkler (m2), design density (mm/min), friction losses (bar), flow (liters per minute) and others according to the NFPA 13 Standard are all indicated within the calculation sheet. The user has access to the independent variables, and the entire calculation sheet is automatically updated after each modification. Above all, the designer is able to have full supervision on both drawings and calculations at the same time (Figure 6).

When it comes to the selection of the other equipment, the most favorable and unfavorable sprinkler groups are detected automatically in order to support the selection of the appropriate fire pump set and water tank (Figure 7).  In this way, the pump is capable of providing the necessary flow and pressure for the most favorable and unfavorable areas, as requested by the NFPA (and also the EN) Standards.

Thanks to the detailed hydraulic calculations which also take into account the characteristic curves of the pumps, the selection of the required equipment is made in the most precise way.

Calculation reports include all the step-by-step and final results in full accordance with the Standard selected. The output also includes a set of 2D & 3D drawings that are automatically generated and updated following the calculation results. A symbolic diagram of the pumps layout is also available (Figure 8)

And finally, the total cost/budget of the installation is also available through a detailed list of the Bill of Materials (fittings, pipes, sprinklers, fire pumps and other elements) for the project.


FineFIRE provides a holistic BIM approach for the design of any kind of sprinkler installation (tree, looped, gridded or any combination) through a sophisticated simulation environment which accurately specifies the fire network installation in compliance with the latest standards. Despite its high parameterization, FineFIRE remains user-friendly, provides the designer with the ability to manage the BIM information at every stage of the design process, and allows collaboration between different users with respect to other CAD and BIM software applications. Most importantly, FineFIRE supports the designer in achieving optimum design solutions by solving possible problems in the virtual world before they happen in the real world.
