Discipline-federated 3D/4D modeling of geotechnical and structural works — clash detection, quantity take-off, and a coordinated single source of truth from design through execution.

PPZIGGURAT's in-house information-management system on SharePoint — controlled documentation, submittal and RFI workflows, QA/QC records, and full traceability from site to design office.
The application we built to run deep excavations — every nail, anchor and pile tracked from drawing to installation, with warehouse, CPM scheduling, instrumented monitoring and reporting on one dataset.

At **Paydar Pey Karan Ziggurat**, we engineer the ground beneath tomorrow\\\'s cities.
For more than thirteen years, we have specialized in one of the most technically demanding disciplines of civil engineering: deep excavations, geotechnical engineering, and structural solutions for complex urban developments. Our work begins where every successful project begins—with the ground.
What distinguishes Ziggurat is the seamless integration of **engineering and construction**. We are both designers and builders. The engineers who develop our geotechnical models are directly involved in project execution, ensuring that every design is practical, buildable, and informed by real-world site conditions. This unified approach minimizes risk, improves constructability, and delivers greater certainty for our clients.
Our expertise spans the full project lifecycle—from geotechnical investigation and engineering analysis to the design and construction of retaining systems, soil nailing, multi-strand ground anchors, bored piles, shotcrete, instrumentation, and geotechnical monitoring. Every project is managed by a multidisciplinary team committed to technical excellence, safety, and quality.
Our engineering team brings more than **eighteen years of professional experience**, having successfully delivered complex deep excavation projects of up to **60 metres** adjacent to occupied buildings and sensitive urban infrastructure, including landmark developments such as **Iran Mall**. We also provide structural engineering services for high-rise buildings and seismic retrofitting solutions for existing structures.
Innovation is embedded in the way we work. Alongside industry-leading engineering software, we have developed proprietary digital platforms that integrate BIM and Project Management Information Systems (PMIS), providing complete visibility throughout the project lifecycle. Our in-house software, **GEOcore**, tracks every soil nail, ground anchor, and bored pile from design through installation, quality assurance, and final documentation.
At Ziggurat, we believe engineering is about more than solving technical problems. It is about creating confidence—for developers, consultants, contractors, and communities. Our mission is to deliver safe, resilient, and efficient engineering solutions that protect people, safeguard neighbouring structures, and provide our clients with complete transparency at every stage of their projects.
**Building Confidence from the Ground Up.**
