BIM Mandatory in Turkey: How to Comply with New Regulations?

Model-based construction management is no longer a choice, it is becoming a necessity. With the gradual compulsion of the use of BIM (Building Information Modeling) in public projects in Türkiye, all stakeholders need to adapt to this process. So, let’s talk about what awaits you in this new period and what role BIMCRONE can play in this transformation. You can find the provision and link regarding this change below.

“(30) The project, drawing, calculation and reports attached to the building permit to be applied in the projects to be determined by the Ministry; shall be recorded in accordance with the principles to be determined by the Ministry, the relevant building information modeling (BIM) standards and numerically in the data infrastructure to be established by the Ministry or the administrations it authorizes, and shall be checked, approved and stored electronically. The condition of the documents written in this article being printed is not required for the transactions to be carried out through the automation system.”

Legal Background: Where Did the BIM Mandate Come From?

As of 2025, BIM usage has become a requirement in large-scale public projects in Türkiye. Along with the Ministry of Environment, Urbanization and Climate Change, institutions such as the General Directorate of Highways (KGM), the State Airports Authority (DHMİ) and TOKİ have begun publishing technical specifications that require BIM-based data production and management in their projects.

This transformation is inspired by similar practices in Europe. In particular, the PAS1192 standards in the UK, Germany’s DIN BIM Norms and Norway’s digital project management models are shaping the roadmap of this process.

Who Is Affected?

With BIM becoming a legal requirement, every stakeholder involved in the process is affected by this transformation:

• Architects and engineers: They have to carry out design processes with BIM-compatible software and standards.
• Contractors and subcontractors: They have to follow up on progress, planning and progress payments through models.
• Employers and investors: They are demanding BIM systems for transparency, data security and project control in the process.
• Project management companies: Planning, coordination and reporting are now carried out in a model-based manner.

What Expectations Does the New Process Begin With?

What Expectations Does the New Process Start With?With BIM, not only modeling but also all dimensions of the process are becoming digital in construction projects:

• The installation of a Common Data Environment (CDE) is now mandatory.
• In project deliveries, IFC, COBie, Excel outputs, data production according to LOD (Level of Development) levels are expected.
• Time (4D) and cost (5D) tracking integrated on a 3D model are becoming standard.
• Revision processes need to be recorded in comparison with the past.

 

 

Why BIMCRONE?

BIMCRONE  is an end-to-end digital BIM process management platform developed in 100% compliance with Turkey’s legal regulations and the special requirements of public projects. It makes your projects not only compliant with the legislation, but also measurable, traceable and optimized.

BIMCRONE’s Strategic Advantages in the Compliance Process?

• Common Data Environment (CDE): All project stakeholders work synchronously on a single digital platform; data loss and communication interruptions end.
• 4D–5D Integration: Planned and realized manufacturing are tracked directly on the model, together with time and cost dimensions.
• Automatic Revision Analysis: Changes are detected instantly with model comparisons, and their effects are reported with artificial intelligence support.
• Standard-Compliant Data Outputs: Effortless compliance with public tenders and control processes is ensured thanks to outputs in common formats such as IFC, XLS, XML.
• Turkish Interface and Templates: Provides ease of use in the field, speed and clarity in control processes.

 

 

 

Where BIMCRONE Makes a Difference

BIMCRONE is a platform developed by keeping the real needs of construction projects in the foreground.

• Project management and file outputs in accordance with legislation,
• Automatic progress table production,
• Three-dimensional progress visuals and detailed progress reports,
• AI-powered revision management, project improvements
• Instantly trackable, end-to-end traceable project management.It simplifies complex processes, reduces human error, and makes your project auditable, transparent, and sustainable.

 

Conclusion and Recommendations

 

Adapting to BIM processes in the new era not only meets the legal obligation, but also makes your project more transparent, more controlled and more efficient. To do this:

• Get BIM consultancy in the early stages of the projects.
• Assign a team and a responsible person to run the BIM processes.
• Make sure that the platform you will use supports legal outputs and process management.

Working with BIMCRONE is one of the most effective ways to ease this transition process and make legal compliance seamless.
