Warehouses present unique challenges in structural engineering. Foundations must support heavy loads from stored goods and equipment while maintaining flexibility for future modifications. Ensuring structural integrity and minimizing risks like cracking or punching shear failures is critical. Additionally, coordinating complex reinforcement plans often leads to errors and delays, affecting overall project timelines and costs. 

Building Information Modeling (BIM) helps address these challenges by providing a clear, comprehensive view of all structural elements and facilitating better collaboration among stakeholders. In our recent project for a warehouse in Freilassing, Germany, CN Europlan utilized BIM alongside ALLPLAN software to streamline the design and implementation of an effective reinforcement strategy. 

Project Overview: Freilassing Warehouse

For the Freilassing warehouse, the bottom plate required significant reinforcement to handle heavy loads and prevent structural issues over time. Our solution involved the use of additional rebars and Halfen Punching Rails specifically for the bottom plate. These elements were designed to enhance the foundation’s strength and durability, minimizing the risk of cracking and punching shear failures. 

Reinforcement Strategy: Rebars and Punching Rails by Halfen

To ensure a robust foundation, we combined additional rebars with Halfen Punching Rails: 

• Rebars were strategically placed to improve the tensile strength of the concrete. By reinforcing the concrete slab, the rebars help distribute loads evenly, reducing the risk of structural damage under heavy load conditions. 
• Halfen Punching Rails were incorporated to prevent punching shear failures around column bases. These rails are essential for distributing localized forces more evenly across the slab, increasing resistance to potential shear failures and enhancing overall durability. 

Automation with ALLPLAN and BIM Integration 

The integration of ALLPLAN software allowed us to automate the design and placement of reinforcement elements, including the Punching Rails and rebars. This automation ensured that each reinforcement component was accurately positioned according to engineering specifications, reducing manual errors and improving efficiency. 

Additionally, the BIM approach enabled our reinforcement BIM teams to control and manage the placement of Punching Rails directly within the digital model. This process provided several key advantages: 

• Improved Visualization: The 3D BIM model offered a detailed view of all reinforcement elements, helping to identify potential clashes or design issues early, which reduces costly adjustments during construction. 

• Better Collaboration: The BIM model served as a single source of truth, improving communication among stakeholders and ensuring alignment on reinforcement requirements. 
• Cost and Time Efficiency: Automated controls within ALLPLAN allowed for quick adjustments and precise placement, minimizing material waste and keeping the project on schedule. 

Key Takeaways

• Targeted Reinforcement Solutions: The use of additional rebars and Halfen Punching Rails provided the necessary support to handle heavy loads and prevent structural failures in the warehouse’s bottom plate. 
• Precision and Efficiency: The automation capabilities of ALLPLAN and integration with BIM allowed for accurate placement of reinforcement elements, reducing errors and facilitating a smoother construction process. 
• Optimized Project Coordination: Using BIM for reinforcement planning improved coordination among project teams, optimizing resources and reducing costs. 

Moving Forward

The Freilassing warehouse project highlights how combining traditional reinforcement techniques with advanced digital tools like ALLPLAN and BIM can effectively address the structural challenges of warehouse construction. This approach helps meet high standards for safety and performance while increasing project efficiency.

Designing the structure of a sports hall involves unique challenges that go beyond typical building requirements. These facilities require expansive, open spaces free of obstructive columns, complicating load distribution. Additionally, the structure must endure dynamic loads from various sports activities while maintaining durability over time. 

The new sports hall in Munich, Germany, faced these specific challenges. To achieve the necessary structural integrity and safety, precise rebar placement and well-coordinated formwork plans were essential. CN Europlan employed advanced BIM (Building Information Modeling) tools to meet these demands, ensuring all structural requirements were addressed efficiently and accurately. 

Project Overview 

The sports hall near Munich is designed to host sports events and community activities. The project required a structural design that ensured functionality, safety, and compliance with architectural standards. CN Europlan’s expertise in BIM and structural engineering was crucial in developing effective rebar plans and formwork designs tailored to these needs. 

Addressing Structural Design Challenges with BIM 

One of the key challenges in the Munich sports hall was integrating a steel profile with specific rebar configurations to maintain the open space design while ensuring structural stability. The starter for the upper column from the beam was constructed using a steel profile welded with 2x 15 Ø28 mm and 2x 14 Ø12 mm rebars. This configuration required precise placement to support the upper columns without compromising the hall’s open space. 

To further reinforce the structure, 2x 12 Ø40 mm rebars were used for the top and bottom longitudinal reinforcements. These rebars were carefully modeled using BIM to ensure they met structural requirements and optimized the building’s load-bearing capacity. The use of BIM technology facilitated the accurate placement and coordination of these elements, reducing potential conflicts during construction and enhancing the structure’s integrity. 

Detailed Integration of Closed Stirrups 

The project also required the integration of numerous closed stirrups in the beam design, which was another critical aspect of CN Europlan’s rebar plans. The closed stirrups were designed to pass through the steel profile, adding further stability to the structure. The application of BIM provided several benefits: 

• Accurate Rebar Positioning: BIM allowed for precise modeling of the closed stirrups, ensuring they were correctly positioned around the longitudinal rebars during concreting. This was essential for maintaining the structural integrity of the beams. 

• Load Distribution Optimization: By using BIM to visualize the placement of the stirrups, CN Europlan could adjust the load distribution within the beams, improving resistance to bending and shear forces—a key requirement for a sports hall subjected to dynamic loads. 
• Enhancing Structural Stability: Modeling the integration of stirrups through the steel profile with BIM added stability to the design, minimizing the risk of structural movement over time. 

Using BIM to Overcome Design Complexities 

The rebar and formwork plans for the Munich sports hall required precise planning due to the complex requirements of maintaining large open spaces while ensuring structural stability. BIM tools enabled CN Europlan to create detailed 3D models that provided a clear visualization of the structural elements, reducing errors and streamlining the construction process. This approach helped ensure that all plans met safety and design standards effectively. 

Future Applications and Insights 

The use of BIM in the structural engineering of the Munich sports hall offers insights that can be applied to future projects. The accurate modeling and planning capabilities of BIM provide practical solutions that other structural engineering offices in Germany can adopt. These methods can help improve project quality, safety, and efficiency.
