Hermanson Opens 81,000-Square-Foot Pipe Fabrication Facility in Kent, Washington

Key Highlights

• Hermanson opened a new Pipe Division Shop in Kent, Washington.
• The facility provides more than 81,000 square feet of fabrication space.
• A 33,000-square-foot pipe yard expands material storage and handling capacity.
• The shop will fabricate prefabricated piping assemblies for local and national projects.
• The investment is aimed at improving field productivity, safety and project delivery capacity.

New Facility Expands Pipe Fabrication Capacity

Hermanson Company has opened a new Pipe Division Shop in Kent, Washington, adding significant fabrication capacity to support mechanical construction work across the Pacific Northwest and other markets.

The facility includes more than 81,000 square feet of fabrication space, a dedicated tradesmen office and a 33,000-square-foot pipe yard. The expanded footprint gives Hermanson additional capacity to produce prefabricated piping assemblies before they reach the jobsite.

The company marked the opening Aug. 25 with a ribbon-cutting attended by employees, customers, industry partners and community members.

For mechanical contractors and construction managers, expanded off-site fabrication capacity can help shift portions of installation work from active jobsites into controlled shop environments. That approach can improve material coordination, reduce field labor requirements and support more predictable installation schedules.

Prefabrication Supports Field Productivity

The new shop is designed around supporting field installation teams, with fabrication processes intended to simplify complex portions of mechanical work before materials reach the jobsite.

The facility's opening also coincided with the 2026 Stratus Innovate Conference, during which industry professionals toured Hermanson's fabrication operations and reviewed the technology and processes used at the facility.

Hermanson said the shop will serve projects throughout the Pacific Northwest as well as national jobsites, giving the contractor greater flexibility in handling prefabricated piping requirements across multiple locations.

The investment reflects a broader construction-industry shift toward prefabrication and modularization as contractors seek ways to address skilled-labor constraints, improve quality control and reduce the amount of work performed in congested field conditions.

For owners and general contractors, expanded fabrication capabilities can also affect procurement and project planning. Early coordination of design, material specifications, fabrication requirements and delivery sequencing becomes increasingly important when prefabricated assemblies are incorporated into a project's schedule.
