Model-based construction management is no longer an option; an official requirement for public projects in Türkiye it is becoming. With regulations coming into force as of 2025, all project stakeholders are expected to comply with BIM (Building Information Modeling) processes.
The obligations introduced by this new era, why they are critical for project management, and how ALGO Architecture assumes a strategic role in this transformation are examined in detail below.
2025 Regulation: BIM Is Now a Legal Requirement
The updated clause in the Planned Areas Zoning Regulation clearly defines the framework for digital project delivery:
“Project drawings, calculations, and reports submitted for building permits shall be prepared digitally in accordance with relevant BIM standards, reviewed, approved, and stored electronically. No printed documentation shall be required.”
Official text: Official Gazette – March 11, 2025
With this regulation, all permitting, implementation, and inspection processes are fully digitalized; model-based data production becomes a fundamental requirement for project delivery.
Legal Background: How Did the Mandate Begin?
As of 2025, led by the Ministry of Environment, Urbanization, and Climate Change:
- General Directorate of Highways (KGM)
- State Airports Authority (DHMİ)
- Housing Development Administration (TOKİ)
- Large-scale public employers
within their published technical specifications have begun mandating BIM-based data production.
This transformation progresses in parallel with European precedents:
The UK’s PAS 1192 standards, Germany’s DIN BIM norms, and Norway’s digital project management models have become reference points for Türkiye’s transformation.
Who Is Affected by the BIM Mandate?
In the new era, nearly all project stakeholders are part of this transformation:
Architects and engineers:
Design processes must now be conducted in compliance with BIM standards.
Contractors and subcontractors:
Progress payments, scheduling, and construction progress are monitored directly through the model.
Employers and investors:
They increasingly demand BIM for transparency, data security, and project reporting.
Project management offices:
Planning, coordination, and reporting are conducted entirely on a model-based basis.
What New Processes Are Expected? (CDE – LOD – 4D – 5D)
Digital project management now requires an integrated approach beyond modeling alone:
- The use of a Common Data Environment (CDE) becomes mandatory.
- Official data formats such as IFC, COBie, and Excel are required in projects.
- LOD levels Data production is controlled according to LOD levels.
- 4D (time) and 5D (cost) model integration becomes standard practice.
- All revisions are stored comparatively with historical records.
This structure accelerates audit processes while significantly increasing project transparency.
Why ALGO?
ALGO Architecture stands out through its BIM workflows fully aligned with Türkiye’s new regulations, interdisciplinary digital coordination expertise, and project management approach.
ALGO approaches BIM in both public and private sector projects not merely as an obligation, but as a quality standard that enhances project performance.
