Mirwais Bridge EPC, Kabul

The Mirwais Bridge project in Kabul combined structural design and construction under EPC responsibility. The completed prestressed-concrete bridge is 500 metres long and 24 metres wide and was delivered in nine months for Suleyman Sahin Inşaat under international project conditions.

Delivering a bridge in this context required engineering, site supervision and construction sequencing to remain closely connected. Material availability, site logistics, structural quality and local coordination all needed to support the same completion programme rather than being managed as separate administrative streams.

Prestressed concrete construction depends on disciplined control of geometry, reinforcement, stressing activities and concrete quality. Site supervision provides the link between the design assumptions and the actual structure being built, allowing deviations to be identified before they become embedded in later work.

Handover to local authorities completed the EPC responsibility. The project therefore represents not only construction of a major structure but also the controlled progression from design through field execution to an accepted public-infrastructure asset.

The published project record states that the 500 m by 24 m prestressed-concrete bridge was completed in nine months. A programme of that duration places strong emphasis on design release, procurement, reinforcement and concrete sequencing, formwork, stressing operations, site access and inspection readiness progressing without avoidable handoff delays.

The significance of the reference is therefore not only the bridge dimensions. It is the combination of engineering and construction responsibility under international project conditions, where site supervision and structural quality control had to remain connected to a compressed completion programme.

Bridge EPC work makes interface ownership visible because structural design, temporary conditions, site production and final acceptance cannot be separated without creating gaps in responsibility. The contractor has to understand not only the permanent structure but also how it will be built, inspected and progressively released.

That experience is relevant to later EPC and contracting work across infrastructure: define the execution basis early, keep engineering decisions close to field conditions, maintain traceable quality records and plan handover as part of delivery rather than as an administrative event at the end.
