De Simone Group

What De Simone Group does

De Simone Group is a Ghanaian privately-held construction conglomerate established in 1964 and headquartered in Tema, providing multi-disciplinary infrastructure solutions across West Africa. The group operates through eight wholly-owned subsidiaries spanning construction contracting (De Simone Limited as the flagship entity), regional construction in Nigeria (Monterosa Construction Limited), Burkina Faso (De Simone Burkina Faso S.A.), Liberia (De Simone Liberia), and Côte d'Ivoire (De Simone Côte d'Ivoire), plus vertical-integration assets in aggregates (Eastern Quarries Limited), ready-mixed concrete (Monolo Plant Limited), and contract mining (De Simone Mining Services). It serves multinational mining companies, diplomatic missions, government entities, banks, industrial manufacturers, and commercial developers across Ghana, Burkina Faso, Liberia, Nigeria, Côte d'Ivoire, and operational extensions to Niger and Mali.

The group's core technical capabilities span civil engineering, building construction, earthworks, structural works, mining infrastructure (including tailings storage facility construction), and SMPP (Structural, Mechanical, Piping, and Process) activities. Eastern Quarries produces approximately 2 million tons per annum of aggregate and road base materials with a 100+ year reserve life. Monolo Plant operates two fixed computer-controlled batching plants in Tema with 35 ready-mix trucks, mobile concrete pumps ranging from 15m to 60m, and a 48-metre pump described as the largest of its kind in Ghana, plus 12 mobile batch plant units and crane/fabrication capabilities. De Simone Mining Services operates over 70 pieces of plant machinery including tipper trucks, excavators, graders, rollers, water tankers, and bulldozers for contract mining and ore haulage.

Revenue is generated through project-based construction contracts, recurring aggregate and ready-mixed concrete sales to both internal projects and the Ghanaian public market, and contract mining services. The go-to-market is direct enterprise field sales targeting large multinational and government clients, with repeat business from established relationships as the primary demand driver. Pricing is quote-based and not publicly disclosed. The group's vertical integration across materials supply, equipment ownership, and multi-disciplinary construction capability reduces subcontractor dependence and supports execution control on complex projects such as the MPS Tema Port Expansion (with Eiffage Genie Civil), CBI's calcined clay cement plant, AngloGold Ashanti's Iduapriem Water Treatment Plant (with Proxa Water), and multiple gold mine TSF programmes.
