MWH Constructors

What MWH Constructors does

MWH Constructors is a US-based, private heavy-civil construction firm headquartered in Broomfield, Colorado, specializing in water, wastewater, and industrial water infrastructure. The company's lineage traces to John D. Watson (founded 1828); the modern MWH Constructors entity was formed in 1993 and operates offices in Broomfield (HQ), Phoenix, and St. Petersburg. The firm employs 1,001–5,000 people and is affiliated with Obayashi Corporation's global water construction platform.

Core capabilities span construction management at-risk (CMS), design-build, and self-performance on projects ranging from approximately $50M to $1.5B+. Technical specialties include Cambi thermal hydrolysis process (THP) systems, where MWH has serviced 20+ of the ~50 worldwide installations, and advanced digital delivery built on 4D/5D BIM, VR/AR, drones, and laser scanning. Recent capital projects include the Bull Run (Envision Platinum) and Saco (Envision Silver) water treatment programs.

The business model is project-based general contracting and construction management for municipal water utilities, with an expanding industrial water segment following the August 2021 acquisition of Methuen Construction. The firm has delivered $6B+ in 100+ projects and managed $3B+ via CMS over the past 10 years. Revenue mechanics combine self-performed work, CM-at-risk fees, and joint-venture participation with partners including Kiewit, Webcor, KG Walters, and Carollo; specific revenue figures are not publicly disclosed.
