**Project Overview:**

**Tehran Metro Line 10** is one of the strategic projects for expanding the capital’s rail transportation network, following an extensive alignment across the northern and west–east areas of the city. The corridor includes key stations such as **Daryacheh Square, Austria Square, and Kuhsar**, as well as sections of long tunnels and associated structures. Its numerous interchanges with other metro lines further enhance its strategic significance within the network and its role in improving connectivity.

The construction activities for this section include **site establishment, positioning of shafts for TBM entry and retrieval, tunnel excavation, construction of station structures, and installation of MEP and ventilation systems**. At several western stations, including **Austria Square and Daryacheh**, physical progress at the worksites and preparations for concrete placement and structural installation have been reported.This stage also involves addressing **technical challenges along the alignment**, including geotechnical considerations and the passage beneath complex urban intersections, requiring disciplined and interdisciplinary **planning and quality control** throughout the execution process.

Behro’s Role in the Project:

Along this complex alignment, **Behro Comprehensive Consulting Engineers**, serving as the **Supervision Consultant and site support consultant**, plays a key and strategic role. Behro’s technical team is responsible for establishing the supervision management framework, coordinating among contractors, controlling construction quality, and monitoring project risks, as well as reviewing and approving key stages, including **shaft leveling, structural concrete placement planning, and supervision of performance tests**. Behro’s presence ensures operational compliance with technical criteria, reduces construction risks, and accelerates the achievement of the project’s schedule objectives.
