Our History


In 1896, George Fennell entered the mechanical contracting business from a small shop in Newport, Kentucky. George H. Fennell & Company grew as they provided various services in the tri-state area, ranging from residential boiler replacements to commercial piping installations.

George’s son Clem Fennell continued the success his father had built in the commercial mechanical service world in what was now called Fennell Company. His son Clem Fennell Jr. became involved in the 1940’s following World War II. The 1950’s, 60’s and 70’s were a period of great growth for the company. Fennell Company became the premier commercial and industrial piping company in the Cincinnati area particularly in the power, utility, and chemical process piping sector.

The Founding of Process Construction Inc.

In the early 1980’s Clem Fennell Jr. along with his sons moved across the Ohio River to Cincinnati Ohio and began Process Construction Inc. The new company continued its heavy industrial piping successes. By the 1990’s Clem Fennell III had become President and the company continued to evolve with the ever-changing mechanical industry including the formation of our HVAC department. The 2000’s saw continued change and growth. Plumbing was added into our offering of services and customers began to expand into food and beverage, manufacturing, pharmaceutical and much more.

Grown in Cincinnati, Ohio

Today, PCI continues to operate as a small family business as Clem Fennell IV now oversees the day-to-day operations as President and our services continue to expand including the recent addition of our Fabricated Systems division which specializes in fabricated mechanical skids which are designed and built from start to finish in our Cincinnati shop.
