About IRANTOPDOWN
IRANTOPDOWN is a registered brand of Farabanasazan Construction Co. For close to a decade we have specialised in excavation support and top-down construction, often on sites where other methods had already run into trouble.
62,000+
Working hours of top-down excavation support without an excavation-related incident
Our team brings together specialists in civil, geotechnical and structural engineering and architecture. Together they have delivered dozens of excavations on sites with severe stability problems, mainly in Tehran and Karaj.
Owners, developers, public bodies and consultants can book a free meeting with us. We review the site and propose the right way to support the excavation before any commitment is made.
