Overview
BM Holding is an Ankara-headquartered Turkish industrial group whose roots go back to 1972, when entrepreneur Bülent Kuyumcu founded BM Mühendislik ve İnşaat A.Ş. (BM Engineering and Construction). The company began with small-scale building work such as office construction and gradually moved into large, complex and risk-heavy civil engineering projects. Over the following decades it built a reputation in heavy construction: large dams (concrete, rockfill, earthfill and RCC), hydroelectric power plants, tunnels and shafts, roads and bridges, natural gas and oil pipelines and stations, marine dredging, land reclamation and ports. From the 1980s the group diversified beyond contracting. It entered energy generation in the early 1980s, geothermal exploration in 2004 and agriculture (horticulture and fertilizer) in 2009; it was also active in tourism before exiting that sector in 2001. In hydropower, BM entered the sector in 1986 with what it describes as Turkey's first build-operate-transfer (BOT) hydroelectric investment, and has since developed, designed, built and operated eight hydropower projects with a total installed capacity of 250 GWh. The group also highlights a series of Turkish firsts, including the country's highest dam by construction date, the first hydropower plant with a rubber (inflatable) spillway, the first concrete arch dam built by a local firm, the first dam built on marshland, and the first private-sector high-enthalpy geothermal discovery. Today BM Holding operates through a group of companies in construction, land development and upstream oil, with subsidiaries such as Pars Anatolian (drilling services and drilling machine manufacturing) and Petrotek Global (manufacturer of internationally standard oil drilling rigs and equipment). Its land development arm has been acquiring high-value land in Antalya and Ankara since 1992 and has moved into urban transformation and land development projects. The group presents itself as an engineering-led organization that brings value to the market through good engineering, extensive R&D and a bold approach to innovation. It remains a privately held, family-linked Turkish group rather than a listed company.
History
BM Holding's history begins in 1972, when entrepreneur Bülent Kuyumcu founded BM Mühendislik ve İnşaat A.Ş. (BM Engineering and Construction) as the group's first company. The firm started out taking on small-scale structures such as office building construction, then gradually moved upmarket. Over the next decade it focused on large-scale, complex and risky construction projects that demanded a sophisticated approach to construction, engineering and project management, carving out a specialized niche. As its construction expertise matured, BM diversified into other sectors. It entered energy generation in the early 1980s. In 1986 it entered the hydropower sector with what it describes as Turkey's first build-operate-transfer (BOT) hydroelectric investment. The group went on to develop, design, construct and operate eight hydropower projects with a total installed capacity of 250 GWh. Its construction record includes a series of Turkish firsts: the country's highest dam by construction date, the first hydropower plant with a rubber (inflatable) spillway, the first concrete arch dam built by a local firm, the first dam built on marshland, and being the first local pilot of a large multinational construction consortium. In 1992 the group began acquiring high-value land in Antalya and Ankara, launching its land development activities, which later expanded into urban transformation and land development projects. In 2001 BM exited the tourism sector, which had been among its past investment interests. In 2004 it entered geothermal exploration, and in 2009 it moved into agriculture, including horticulture and fertilizer. In the energy field the group also claims Turkey's first private-sector high-enthalpy geothermal resource discovery and the first CSP-geothermal hybrid energy system. Today BM Holding operates as a group of companies active in construction, land development and upstream oil. Its subsidiaries include Pars Anatolian, established to offer the group's ten years of drilling machine manufacturing knowledge, experience and equipment to operator companies in the drilling sector, and Petrotek Global, a manufacturer of internationally standard oil drilling rigs and equipment. The group's general business approach is to bring value to the market through good engineering, extensive R&D and a bold approach to innovation. It remains headquartered in Ankara and privately held.
