Bouygues Construction and Colas Rail, the rail subsidiary of the Colas Group, completed the acquisition of Alpiq InTec AG and Kraftanlagen München GmbH, whose activities merged into Alpiq Engineering Services.
Alpiq InTec and Kraftanlagen München specialise in both hard and soft services within construction and energy sectors as well as industrial and transport infrastructures. All of these activities are orchestrated by a workforce of around 7,650 people, and generated sales of approximately 1.7 billion Swiss francs in 2017, chiefly in Switzerland (57 percent), Germany (24 percent) and Italy (12 percent).
This acquisition strengthens Bouygues Construction position as a leading player in the energy industry across Europe and is in line with its development strategy for continued growth in the market.

Through this operation, Bouygues Construction has reinforced its roots in Switzerland in businesses that closely complement those of its subsidiaries such as: Bouygues Energies & Services Switzerland, Losinger Marazzi, VSL and PraderLosinger. Meanwhile, the acknowledged know-how of Alpiq Engineering Services will also enable Bouygues Construction to expand its portfolio of offers, particularly for carrying out complex projects in industry and energy production. Last but by no means least, Alpiq Engineering Services will provide an opportunity for entering major new European markets, particularly in Germany and Italy.
Colas Rail’s acquisition of Alpiq Engineering Services’ rail activities has strengthened the Colas Group rail subsidiary’s expertise in the field of catenaries, a high-value-added business, and given it access to new growth markets. Colas Rail, a leading company in the rail sector, has expanded its portfolio of solutions and know-how, penetrated the Swiss and Italian markets and strengthened its presence in Central Europe and the United Kingdom.
This acquisition was confirmed on the basis of an enterprise value of 850 million Swiss francs (700 million Swiss francs for Bouygues Construction and 150 million Swiss francs for Colas Rail). The price paid at the closing for the acquisition of all shares was paid in cash.
