BAUER Aktiengesellschaft is a construction and machinery manufacturing company based in Schrobenhausen in Upper Bavaria, Germany.

[2] For over a century, the coppersmith's shop participated in the establishment of breweries, performed roofing work with copper and manufactured objects for everyday household use.

In 1902, Andreas Bauer drilled an artesian well for the new railway station water house[3] in Schrobenhausen, which would make well-drilling a new business segment of the company.

It was with this reference that he switched operations toward those of a well-drilling company and would soon become active with building wells and water supply facilities for cities and industrial enterprises all over Bavaria.

Karlheinz Bauer, born in 1928, and company shareholder since 1953, became the sole managing director in 1956 and switched operations to specialist foundation engineering.

BAUER Maschinen GmbH with the companies Klemm Bohrtechnik, MAT Mischanlagentechnik, RTG Rammtechnik, Eurodrill, TracMec and PILECO, became an independent operator on the market.

In 2010, cutter technology celebrated its 25-year anniversary, and the biggest plant-based purification facility in the world to date was completed in Oman by Bauer Resources.

This was followed by contracts for the foundation work of what will be the world's tallest building[5] (Jeddah Tower) and Europe's tallest building[6] (Lakhta Center), as well as in 2014 the execution of the company's largest foundation engineering contract in Germany to date: the Schwarzkopf Tunnel bypass rail project in the Spessart region (Schwarzkopf Tunnel is part of the Main–Spessart railway).

In 2015, Bauer celebrated its 225th anniversary and won the largest single contract in the company's history with the Kesslergrube remediation project.

Since then, the previous Executive Board members Peter Hingott and Florian Bauer have formed the top management team.

At the same time, former CFO Hartmut Beutler has returned to the Executive Board of BAUER AG and will temporarily form the dual leadership together with Peter Hingott.

[10] The companies of the Group has been a major driving force in the development of various construction methods for specialist foundation engineering.
