TÜV SÜD BIM model check

Most building owners from the public sector request BIM projects under IFC setup. This means that BIM models from different authoring tools are exported, imported and coordinated based on ISO 16739 (open BIM, IFC). TÜV SÜD BIM model check and open BIM project certification include reviews and checks on BIM authoring, BIM coordination and BIM management levels. The solution is co-developed by TÜV SÜD and Solibri and is based on Solibri (“SMC”) Technology. TÜV SÜD BIM model check for open BIM / IFC projects goes beyond just clash detection. It is made for BIM project / BIM model certification according to ISO 16739 and general virtual design and construction quality.

Open BIM projects often lack proper BIM implementation and common (IFC) model authoring across all trades according to ISO 16739/ Building Smart nomenclatures. Thus, the coordination ability of all trade models such as clash detections, quantity take-offs or required design for maintainability (and many other use cases) are usually unattainable or require huge time and quality risks. Many projects use Solibri to process clash detection as a single item of the BIM models. Based on TÜV SÜD BIM Management expertise, Solibri Technology is a powerful and complete project review. In combination of Solibri Technology and neutral TÜV SÜD BIM project certification, all stakeholders will get to enjoy optimal and complete quality and risk management for their open BIM / IFC projects.

TÜV SÜD BIM model check powered by Solibri and open BIM project certification help building owners, project managers, consultants and contractors improve quality and identify risks. We aim to achieve best-in-class open BIM (IFC) project outcome. TÜV SÜD BIM experts have developed Freemium BIM model check based on Solibri that covers all four quality and risk areas. It also rapidly verifies 65-100 critical quality and risk items in every single IFC BIM model of your project. 

1. Specify the world coordinate in X, Y and Z format which defines the project base point for all open BIM / IFC models of your BIM project.

2. Specify the rotation to the north in degree format. This is important to combine all the open BIM / IFC models in the TÜV SÜD Solibri dashboard.

3. If an EIR (Exchange Information Requirement) has been created, attach the list of required elements and parameters in Excel format. This is essential especially if you have chosen the extended TÜV SÜD BIM model check. EIR-based LOIs are relevant to benchmark your project against ISO 16739 and execute a BIM review against your BIM project requirements.

IFC MODEL REQUIREMENTS FOR TÜV SÜD MODEL CHECK POWERED BY SOLIBRI:

1. Clear and full trade name or abbreviation (e.g. SAN, ELT, STR, HVAC) in the IFC file name so that your trade models can be technically identified in TÜV SÜD Solibri dashboard.

2. Export the shared grid and make it visible in every open BIM model and IFC file.

3. Ensure that the 3D body is available at the common project base point of each IFC model. This ensures that all trade models can be federated as accurate Solibri project model.

4. Create all breakthroughs as openings (not as objects) in the host wall / ceiling of your open BIM / IFC model. Thus, all openings designed by the individual trades must only be modelled and delivered in the structural or architecture IFC models of your BIM project.

5. Export IFC file from the authoring software according to the relevant trade definition in the IFC export settings (e.g. sanitary, fire protection, structure, mechanical equipment, etc.). This is to ensure that a basic ISO 16739 setup is enabled.

6. Model all HVAC elements in 3D and assign them according to their mechanical system.

7. Model all pipes and ducts with their respective connections to each other.

8. Model the elements such as pipe and duct insulation, radiators, cable routes, suspended ceilings, sprinklers, smoke detectors and fire detectors in 3D, to enable TÜV SÜD model check to detect issues on them.

9. Identify walls and ceilings with component activation by their name or by a parameter to ensure that TÜV SÜD model check can identify all elements during the check.

10. Define the opening direction of emergency exit doors by a parameter so that the custom Solibri rulesets by TÜV SÜD can detect issues within these trades. 

TÜV SÜD combines visual benchmarks with plug-n-play digital items such as BCF and coordination reports to provide information for technical project members as well as easy-to-read reports for project owners and investors.

TÜV SÜD BIM model check will deliver:

1. BIM model check: 60-100 most important “Dos & Don’ts” for optimal BIM structured in four checking categories that address bot technical and commercial aspects of your project.

2. Risk assessment based on ISO 31000: Neutral and independent TÜV SÜD report highlights the risk level of findings, quality issues, focus items and items that need immediate attention.

3. Solibri coordination report enables a plug-n-play takeover of all open BIM / IFC findings. The Solibri-based is the complete and extensive technical result roadmap for BIM authors, coordinators and managers. Based on your selected BIM model check package, TÜV SÜD BCF report will also be delivered.

4. BIM project review report and project certificate by TÜV SÜD: The extensive report summarises the status and optimisation aspects of your open BIM / IFC project. For ISO 16739, TÜV SÜD BIM project certificate is issued to endorse best-in-class BIM execution. 

Every project has its unique use cases and project dependencies on technical/engineering, technology, process and workflow. TÜV SÜD’s experience and the use of the reliable Solibri model checker has shown great effects towards digital quality and risk management for BIM projects in the following project stages:
