What Dammarsberg Entreprenad does

Dammarsberg Entreprenad AB is a privately held Swedish civil engineering and infrastructure construction firm headquartered in Sollentuna, with operations spanning the Greater Stockholm and Mälardalen regions. Founded in 1970 and operating for more than 50 years, the company delivers ground and infrastructure works including pipeline and utility installation (electrical cable, district heating, fiber, water and sewage), excavation and earthwork, asphalting, fine grading and landscaping, paving and stone setting, and other groundwork. A wholly-owned subsidiary, Turebergs Mark & Anläggning AB (acquired September 2021), complements the parent company's capabilities with additional ground and construction resources, while an in-house vehicle workshop in Sollentuna serves both corporate and private customers.

The business operates a project-based revenue model under both fixed-price (fastpris) and time-and-materials (löpanderäkning) contracts, with multi-year municipal and utility engagements. Customers are concentrated in two primary verticals: Swedish municipalities and government bodies (including Sollentuna, Enköping, Järfälla, Håbo, and Stockholm) for roads, parks, and urban development; and energy and utility operators (Ellevio, Vattenfall, SEOM, GlobalConnect) for grid, district heating, and fiber deployment. Additional clients include port operators (Stockholms Hamnar) and infrastructure contractors (Craftor, Abeka). The company owns a machinery fleet ranging from 1 to 17 tons and holds ISO 9001, 14001, and 45001 certifications.

Distribution is direct enterprise and government sales with no intermediary channels; most customer relationships exceed 10 years. The company maintains a regional office footprint (Sollentuna headquarters, Uppsala, Enköping) and has been recognized with the Di Gasell 2025 designation and Årets Företagare Sollentuna 2026 award, signaling sustained multi-year growth and entrepreneurial credibility. Leadership consists of four co-owners — Jesper Hagstedt (CEO), Björn Westman (Operations Manager), Daniel Bergholtz, and Stefan Jargéus (Estimating Manager) — with no external institutional ownership indicated.
