HALL-IRWIN HISTORY
How it all began.
Thanks to George W. Hall and Hale Irwin Sr., we have an amazingly resilient company with a solid backbone built on honesty, integrity, dedication, and hard work.
1963
George and Hale met in 1958 while working at Hugh Phillips Construction in Greeley. They were both superintendents building houses. As they continued their construction career they realized they both had the same problem – finding a pipe crew that could stay ahead of their construction schedule. So in August of
So how did Hall-Irwin get its name? Well, a good friend of George and Hale told them, “If you have faith in your business, you should stand behind it and put your name on it.” With that advice, they took both of their last names and created Hall-Irwin Construction Company. Hale handled operations in the field and George managed the business operations, finances, and estimating.
1974
Hall-Irwin began with only a few employees. However, they quickly grew to nearly 100 workers just in the pipeline crew. In the 1960’s, they brought in the largest excavator that Greeley had ever seen railed in by train, a Northwest excavator that only used hydraulics to operate the stick and bucket, the rest was powered by chains and cables. In 1968, Hall-Irwin added more services including curb and gutters, plumbing, heating, and even building custom homes up until the mid 70’s.
Then in 1974, Hale Irwin Jr.’s golfing career took off, and Hale Irwin Sr. decided to retire from the construction business so that he could tour with his son. At this time, he asked George to buy him out, and George agreed. That same year, Hale Irwin Jr. won his first U.S. Open.
1983
The company launched into the aggregate business in the mid-1980’s. They found it difficult to find quality aggregate at the right price for their pipeline projects, so they bought a farm from Renoyld Herbst and started mining aggregate on that land. While mining, the pits filled up continually with groundwater. Due to evaporation, they either had to pay for the loss of water, use augmentation, fill the pits with dirt, or find a way to otherwise keep the groundwater out. So in 1985, Hall-Irwin built the first slurry wall around a gravel pit (the Herbst Pit). This marked the first slurry wall to be constructed around a gravel pit in North America; some say it was the first in the world, but George is a bit skeptical of that fact.
By 1983, George’s son, Bret Hall had joined the family business and continued Hall-Irwin’s growth. Bret worked at the company throughout high school and college, doing earthwork along with the hard manual labor of laying pipe. In 1980, after graduating from CSU with a degree in Construction Management, Bret began working at Hall-Irwin full-time. In the following years, he worked as a superintendent, project manager, and estimator, before eventually becoming our Chief Operating Officer.
1997
Hall-Irwin’s services continued to expand into the 90’s, by which point we had begun self-performing landscaping and asphalt paving, even purchasing an asphalt plant to supplement this endeavor.

With a very talented staff on board, we decided that we had the capacity to expand even further, and in the year 2000, Hall-Irwin became a general
