Riedel Bau AG Holding

What Riedel Bau AG Holding does

Riedel Bau AG Holding is a privately held, family-owned German construction group headquartered in Schweinfurt, Bavaria, operating under the corporate name Riedel Bau AG and trading as Firmengruppe Riedel Bau. Founded in 1899 by master builder Johann Riedel, the group has grown over 125 years into a diversified construction services platform serving commercial, industrial, public-sector, and residential clients across Germany. Its service portfolio spans structural and civil engineering (Hochbau/Ingenieurbau), turnkey general contracting (Schlüsselfertigbau) delivered on fixed-price fixed-timeline terms, real estate development and sales (Bauträger/Projektentwicklung), building renovation (Bauen im Bestand), and ready-mix concrete production and delivery from its own Transportbetonwerk in Bergrheinfeld.

The group's operational backbone combines Building Information Modeling (BIM) methodology — recognized with the 2025 BIM-Preis Bayern and BIM-Champion first-place awards — with vertically integrated delivery through wholly-owned subsidiaries including TM Mainfranken Tiefbau GmbH (civil engineering), Riedel TGA-Planungsgesellschaft mbH (technical building equipment planning), Riedel GSM GmbH & Co. KG, and the acquired Maler und Verputzer (painting and plastering). Certifications include DIN EN ISO 9001:2015 (audited annually for over 25 years), EMAS environmental management registration, AMS BAU occupational safety verification, and IPA Kandidat status for integrated project delivery. The company maintains a documented reference base of 600+ completed projects and a nationwide footprint spanning Schweinfurt, Erfurt, München, Berlin, Bergrheinfeld, Haßfurt, Karlstadt, Sennfeld, and Waldbüttelbrunn.

Riedel Bau generates revenue primarily through fixed-price turnkey construction contracts, individual trade-package contracts (Rohbau, Tiefbau, Ingenieurbau), unit-priced ready-mix concrete and pump rental sales from the Bergrheinfeld plant, and developer margin captured on the sale of self-developed residential and commercial properties. Customer mix is split between enterprise clients (e.g., ZEISS, BMW dealerships, Singulus Technologies, Kali & Salz, Mainfrucht/Grünewald), public-sector tenders (e.g., Bundesamt für Strahlenschutz, Staatsbauamt Erfurt, Stadt Rostock), and private buyers of developed real estate. Distribution is exclusively direct via enterprise field sales, public tender bidding, and property marketing — no reseller or distribution network exists. All distribution, marketing channels (website, social media, customer magazine, regional sports sponsorship), and operational activities are conducted within Germany.
