What Runkel does

Runkel is a German family-owned construction company group founded in 1898 and headquartered in Siegen, operating through two principal divisions: Runkel Hochbau GmbH (general construction contracting) and Runkel Fertigteilbau GmbH (precast concrete manufacturing). The company delivers turnkey construction projects (Schlüsselfertiges Bauen) at fixed prices and agreed deadlines, acting as general contractor (Generalunternehmer) and general developer (Generalübernehmer) for industrial, retail, logistics, office, healthcare, education, and residential clients across North Rhine-Westphalia and Thuringia. Production runs from two computer-optimized precast plants in Wilnsdorf and Gotha, producing structural concrete elements, architectural exposed concrete, prestressed components, and custom special elements with just-in-time delivery and on-site assembly.

Runkel monetizes through project-based one-time contracts for turnkey construction, hardware sales of prefabricated concrete elements, and professional services including project development (via ImmoWert), PlanConsult planning and consulting, New Work workspace advisory, project supervision (Betreuung), and ESG-Score sustainability advisory. Pricing is individually quoted per project with fixed-price guarantees for turnkey deliveries, typically structured as multi-year contracts. Customer engagement is direct enterprise field sales with personal project supervision; the company does not use resellers or distributors. Brand and thought leadership are reinforced through a blog (Infocenter), newsletter, and active social presence on Facebook, YouTube, Instagram, and LinkedIn.

The group operates with approximately 170 employees across its three locations and is led by fifth-generation Managing Shareholder Marc Alexander Runkel, who assumed group leadership in 2021. Notable reference customers include ALDI Hennef, REWE XL Neunkirchen, LIDL Siegen, ABUS Security World Wetter, Thomas Magnete Herdorf, DRK Köln, OCS Bochum, Jacoby-Studios Paderborn (designed by David Chipperfield Architects), VGP Park Gießen, and Altenheim Deuz Netphen. Runkel holds Concrete Sustainability Council (CSC) certification and operates its own quality control laboratory, with additional subsidiaries including ImmoWert Immobilienmanagement GmbH and participation in Campus Siegen Mitte urban development joint venture.
