Schmidt-Diehler Bauunternehmen is a construction company with roots stretching back to 1874, when architect Wilhelm Schmidt-Diehler established the original business in Frankfurt am Main. Over its 150-year history, the company weathered social and economic upheaval, passing through the hands of several generations of leaders and adapting its technology and services in response to new demands. After World War I, it was run by the Krämer family, with Adam Krämer and later his son Ludwig guiding the firm through challenging periods.
In the twenty-first century, the company came under the direction of civil engineer Eckhart Wagner, who expanded both its revenue and workforce. Leadership transitioned to Samir Muratovic in 2019, who also managed AS Bau GmbH before the two companies merged in early 2024. Schmidt-Diehler’s headquarters are now based in Bad Soden am Taunus, just outside Frankfurt, occupying roughly 32,000 square meters of land and 11,000 square meters of office space.
Schmidt-Diehler’s activities cover building construction and civil engineering, with a focus on large-scale projects such as data centers, residential developments, industrial and hotel complexes, and office buildings. Its operations span Frankfurt, the wider Rhine-Main region, and projects throughout Germany. The company emphasizes sustainable construction methods, including high-efficiency building standards like KfW 40. With around 11 to 50 employees, Schmidt-Diehler positions itself as a regional specialist capable of managing complex projects rapidly, evidenced by its continued investment in technology and infrastructure.
