Shimmick Construction Company, Inc. (SCCI) provides heavy civil construction services primarily focused on water and wastewater infrastructure projects. The company offers construction management, design-build delivery, and general contracting services for water treatment plants, wastewater treatment facilities, pipelines, tunnels, pump stations, and dams; it also specializes in marine construction, bridge building, and environmental remediation. Shimmick operates across the United States, with a strong presence in the western and central regions, targeting municipal governments, water districts, and federal agencies as primary customers.
Founded in 1970 and headquartered in Irvine, California, Shimmick traces its roots to a legacy firm established in 1924, positioning it as an established player in the infrastructure segment of the construction industry. The company functions as a standalone public entity following its separation from Tutor Perini Corporation through a spin-off completed in 2024, which marked a significant strategic reorganization to focus exclusively on its core water and wastewater expertise. In late 2024 and 2025, Shimmick secured major contract awards exceeding $1 billion, including design-build projects for water recycling plants in California and wastewater treatment expansions in Texas, alongside strategic alliances with engineering firms for sustainable infrastructure initiatives.
