This is the second time DELCO collaborates with DOOSAN on a project with urgent timelines, difficult construction conditions, and stringent technical and safety requirements.
Fit-out and upgrade of a two-storey factory
In August 2025, DELCO continues its work with DOOSAN on the expansion of the Doosan Electro-Materials factory at Dai An Industrial Park, Hai Duong . DELCO takes charge of the entire scope from design to fit-out construction of a ready-built factory for lease, upgrading it from a one-story to a two-story building, combined with cleanroom installation. The project is expected to complete on a tight schedule of just 83 days.
The greatest challenge of the project is that the entire steel structure assembly and construction of over 1,000 m² of deck floor take place inside the existing ready-built factory. The DELCO team develops suitable erection methods and construction plans to both protect the current structure and ensure no impact on surrounding production activities.
In parallel with the structural works, DELCO also designs and builds an inspection room that meets cleanroom standards equivalent to Class 10,000, serving the factory’s electronic equipment inspection process. The room is equipped with 4 air handling units (ACU 200,000 BTU), together with fire-resistant panel walls and ceiling. In addition, the entire factory ceiling is designed to withstand loads that allow movement and technical operations above.
Safety-first construction – the project’s top priority
As a factory belonging to a multinational corporation, Doosan Electro-Materials operates with very high technical and safety standards. Therefore, all construction activities in the project are strictly controlled, from work processes and construction methods to risk prevention measures.
From the start, DELCO develops an overall safety plan for the entire project, including risk analysis, emergency response procedures, and control of each construction item. All personnel involved undergo safety training and are fully equipped with protective gear before entering the site.

DELCO also strictly complies with plant access control regulations, ensuring only qualified personnel are permitted to work on-site. Each construction zone is marked with warning signs, dedicated pathways, and monitoring systems to minimize risks. With this thorough preparation, DELCO commits to ensuring the technical, quality, and safety standards of the project, fully meeting DOOSAN’s production needs.
