What VDH LTD does
VDH LTD (ВДХ АД) is a Bulgarian general construction and engineering company headquartered in Sofia with a regional office in Sliven and a production base in Mechkarovo Village. It is a controlled subsidiary of Hydrostroy AD (Хидрострой АД), which acquired the company in 2016 and subsequently rebranded it from Vodastroy 98 AD. The firm operates across five core service lines: transport infrastructure (railway, tram, and road construction), energy infrastructure (gas pipelines, traction substations), water and sewerage infrastructure, residential and public building construction, and monument/heritage restoration. It reports market share exceeding 35% in Bulgarian railway construction and over 50% in national gas transmission and distribution network construction, built on 55+ years of operating history via its predecessor state enterprise.
The company operates an integrated production base at Mechkarovo Village that includes a metal workshop with certified welding procedures (WPS 001 through WPS 11-111), a vibro-polygon for concrete elements, an Italian-machinery prefabricated thermopanel line producing Canadian-style building panels at a capacity of 32 panels per shift, quarry operations with inert material processing, and a transport and machinery base. It is registered in Bulgaria's Central Professional Register of Builders for all five construction groups and holds ISO 9001, ISO 14001, ISO 45001, and ISO 27001 certifications. Engineering, design, author supervision, and laboratory testing services are bundled with construction contracts.
VDH generates revenue almost exclusively through public procurement contracts awarded by Bulgarian national and municipal government buyers (NKJI, Bulgartransgaz EAD, Road Infrastructure Agency, Sofia Municipality, ViK operators), and increasingly through consortium structures (Evropat DZZD, DZZD Vistra, DZZD Hydrovodstroy) used to bid on larger EU-co-financed packages. Revenue is project-based and one-time per contract, with pricing determined by competitive tendering rather than commercial negotiation. Secondary revenue comes from in-house production of construction materials (thermopanels, concrete, inert materials) sold alongside contracted works.
