Straßen- und Tiefbau GmbH Eilenburg

What Straßen- und Tiefbau GmbH Eilenburg does

Straßen- und Tiefbau GmbH Eilenburg is a mid-sized German construction firm headquartered in Eilenburg, Sachsen, with a branch in Wiedemar near the A9 Schkeuditzer Kreuz, operating primarily in the federal states of Sachsen and Sachsen-Anhalt. The company delivers integrated road and civil engineering services — Straßenbau (new build and reconstruction of roads across all construction classes), Tiefbau (constructive earthwork), Kanalbau (canal and sewer construction, including wastewater treatment plants up to 5,000 EGW), Trinkwasserleitungsbau (drinking water pipeline installation), and development of residential and commercial areas — and has added Baumaschinenvermessung (construction surveying using tachymeter and GNSS) as a technical service line. Projects are executed with a modern equipment fleet from Komatsu, Volvo, Doosan, and Sany, supported by BRZ construction calculation and invoicing software. The company is privately held as a GmbH under the Porzig family (managing directors Dipl.-Ing. Leander Porzig and Martina Porzig, with Thoralf Kölzsch as Technical Director) and holds an RAL-Gütezeichen Kanalbau (Group AK2; VP), DVGW certification, Zert-Bau membership, and IHK/HWK Leipzig memberships that are prerequisites for public sector bidding.

The firm secures work almost exclusively through public procurement and competitive tendering, with documented clients including the Federal Republic of Germany (Bundesstraßen B2, B6, B184 and others), the state governments of Sachsen and Sachsen-Anhalt, and municipalities such as Leipzig, Wurzen, Eilenburg, Bad Düben, Jeßnitz, and Bad Schmiedeberg, plus the Werk Leuna chemical complex for industrial access roads. Revenue is project-based and transaction-fee in nature: contracts are awarded via public tender, and pricing is not publicly disclosed. The go-to-market is sales-led, driven by prequalification, certifications, regional track record, and direct relationship with public clients rather than by consumer marketing, despite a presence on Instagram and Facebook and a corporate website used partly for recruitment. The company employs approximately 80 staff (per job-posting evidence), operates as a non-listed private GmbH with no external investors or funding rounds, and traces its history to a 1927 trade license before re-founding in its current legal form on July 1, 1990.
