Our Diversity

Since its founding by Jack Kelly, Sr. in 1923, JH Kelly has grown into one of the largest industrial mechanical contractors in the Pacific Northwest.

  • From building foundations and structural steel, to process piping and instrumentation & control systems – our experienced team can handle it from the ground up.
  • We are a self-performing, industrial general contractor with a reputation for completing complex, multi-craft projects under challenging schedule constraints.
  • We’re diversified from a trade, industry, and geographic perspective. JH Kelly’s teams work at manufacturing facilities throughout the greater Pacific Northwest and beyond.

Solutions Providers

It’s not unusual for JH Kelly to be brought on as part of an owner’s project team during the feasibility stage. Working in parallel with the process provider, JH Kelly will collaborate with engineering resources to produce an initial scope, cost and schedule. Our Project Managers, Estimators, and Craft Supervision cover all trades and are versed in multiple industries giving our team a unique perspective.

Design Build / Design Assist

We Provide Options

JH Kelly partners with trusted engineering service providers to Design-Build your project or integrate with your existing design team, providing Design-Assist services.

If you’re an industrial manufacturer and speed to market is your priority, Design-Build will prove to be your most productive contracting strategy. We represent one company with the ability to drive a cost-effective design execution strategy through pre-construction. We then hit the ground running in the field by self-performing all trades with captive labor resources and highly experienced craft supervision.


Draw It Once Mentality

The cornerstone of a safe and productive project is the maximization of prefabrication, which requires accurate and timely detailing.  While the tools have changed since the days of drafting boards and isometric sketch pads, JH Kelly’s commitment to detailing and fabrication has not.

Our team of dedicated in-house professionals use a combination of the latest 3D, Virtual, and BIM technologies to detail, plan, visualize, and track projects across all of the disciplines we construct. Direct connection to our fabrication shops and field teams maximize efficiency, and our multi-trade experience allows us the unique insight to approach potential issues with solutions that save time and money for the entire project.
