What Slayden does

Slayden Constructors, Inc. is a Pacific Northwest heavy-civil construction firm headquartered in Salem, Oregon, operating as a U.S. Regional Division of MWH Constructors. Founded in the 1980s, the company specializes in water and wastewater infrastructure for municipal utilities, water commissions, federal agencies (notably the U.S. Army Corps of Engineers), and select industrial clients across Oregon, Washington, and Idaho. Its core delivery scope includes water and wastewater treatment plants, pump stations, reservoirs, pipelines, dams, fish passage and fisheries facilities, and supporting heavy-civil work, with individual project values ranging from approximately $3M to $176M. The company self-performs critical-path scopes (concrete, mechanical, process systems) rather than acting as a pure general contractor, and operates from two Oregon locations: a Salem headquarters opened in January 2024 (housing up to 35 people with a dedicated bid room) and a Stayton fleet operations base retained from its 30+ year prior presence.

The company's technical differentiator is 25+ years of experience in alternative and collaborative delivery — Construction Manager/General Contractor (CM/GC), Construction Manager at Risk (CMAR), Design-Build, and Progressive Design-Build — which positions it for early engagement on complex treatment plant and dam projects where preconstruction value engineering, constructability review, and schedule certainty are decisive in owner selection. Supporting capabilities include BIM, Virtual Design & Construction (VDC) software, 3D drone mapping for earthwork and site-utility modeling, and an in-house safety program (Improve-It) that has produced consecutive AGC national and regional safety awards (CSEA 2024, 2025; ROSE and PRIDE awards across multiple years). Slayden combines this regional specialization with the national resources, subcontractor databases, and commissioning expertise of parent MWH Constructors.

Revenue is generated entirely through project-based construction contracts awarded via competitive RFP and qualifications-based selection, with multi-year durations and individually negotiated pricing tied to scope, complexity, and delivery method. The go-to-market is enterprise field sales: relationship-driven pursuit of municipal and federal procurements, supported by active participation in AGC Oregon-Columbia and PNCWA, university and apprenticeship recruiting pipelines (Oregon State, Oregon Tech, Boise State, George Fox, Northwest College of Construction), and a track record of repeat work with regional utilities. Notable recent projects include the $176M Spokane Riverside Park Water Reclamation Facility, the $78M Medford Duff Water Treatment Plant expansion, the $92.3M Salem Willow Lake WPCF improvements, the $78M Tri-City Water Pollution Control Plant expansion, and the $27M Cabinet Gorge Dam Fish Passage Facility for Avista.

Core offering

Slayden is a civil construction contractor that self-performs and manages the construction of complex water and wastewater infrastructure, including drinking water treatment plants, wastewater reclamation facilities, pump stations, pipelines, dams, fish passage facilities, and fisheries projects. The company provides preconstruction services (cost estimating, value engineering, constructability review, scheduling, risk management) and delivers projects via alternative contracting methods such as CM/GC, CMAR, Design-Build, and Progressive Design-Build for municipal, federal, and industrial clients in the Pacific Northwest.

Product overview

Slayden is a civil construction contractor specializing in water and wastewater infrastructure in the Pacific Northwest. The company operates as a U.S. Regional Division of MWH Constructors and offers a comprehensive portfolio of construction services organized around three core project categories: Water Treatment Construction Services (including drinking water facilities, reservoirs, filters, pump stations, and river intakes), Wastewater Treatment Construction Services (including treatment plants, headworks, screening, lift stations, and nutrient removal), and Dams/Fisheries/Hydro Construction Services (including dam repair, fish passage facilities, fish ladders, and hydropower infrastructure). These core offerings are supported by service capabilities including Alternative Delivery Services (CM/GC, CMAR, Design-Build, Progressive Design-Build), Preconstruction Services (cost estimating, value engineering, constructability reviews), and Construction Services (self-performance, QA/QC, commissioning). Slayden does not offer a unified software platform but rather provides integrated project delivery across the full project lifecycle from preconstruction through construction and commissioning.

Broad incumbents

• McCarthy Building Companies: National contractor with a significant water/wastewater treatment plant portfolio pursuing collaborative delivery. Comparable in alt-delivery and self-perform approach to Slayden, though typically operating at larger project sizes nationally.
• Mortenson Construction: National contractor with a strong water/wastewater practice pursuing CM/GC and Design-Build treatment-plant projects. Relevant because it competes for the same alternative-delivery procurements Slayden targets and brings vertically integrated resources.
• Kiewit Infrastructure West: Division of Kiewit, one of North America's largest heavy-civil/water contractors. Competes with Slayden on large alternative-delivery water/wastewater projects in the Pacific Northwest and brings greater bonding capacity for mega-projects.
• PCL Construction: Large Canadian-headquartered general contractor with a U.S. civil infrastructure practice covering water treatment and heavy civil work. A relevant broad incumbent competing in design-build water pursuits.
• Granite Construction: Heavy-civil and water-resources contractor active in the Western U.S. with overlapping scope on pipelines, dams, and treatment facility construction. A comparable public-heavy-civil incumbent.
• Walsh Construction: Heavy-civil builder active in water/wastewater treatment plant construction across the Western U.S. Comparable because it pursues CM/GC and Design-Build municipal treatment work similar to Slayden's project mix.

Direct peers

• Garney Construction: National water and wastewater treatment-plant contractor specializing in collaborative delivery for municipal utilities. Highly comparable to Slayden because of similar self-perform capabilities, focus on treatment facilities, and concentration on CM/GC and Design-Build water projects.
• Sundt Construction: Heavy-civil contractor with a dedicated water/wastewater treatment plant group that self-performs concrete and process work. Closely comparable to Slayden in scale, alternative-delivery experience, and Pacific Northwest/Southwest project mix.
• MWH Constructors: Slayden's parent company and the most directly comparable peer: a global water/wastewater infrastructure constructor delivering treatment plants, pump stations, and dams. Highly relevant because Slayden operates as a regional division of MWH with overlapping capabilities in CM/GC and Design-Build delivery.

Regional players

• Hoffman Construction: Pacific Northwest-headquartered heavy-civil and water/wastewater contractor based in Portland, OR. Direct regional competitor on Oregon and Washington treatment-plant and dam projects with comparable self-perform culture.
