At the end of the day, every contractor wants to send their workers home unscathed. To this end, Hall-Irwin created a Safety Committee to more thoroughly integrate a mentality of care for and commitment to the wellbeing of the people we work with. This committee is currently led by our Safety Manager, Chris Dray, and comprised of five other members: David Hollerbach (Project Manager), Josh Turnwald (Project Manager), Garrett Downey (Project Engineer), Mike Smith (Operator), and David Zeigler (Superintendent). Together, they embody the intentions of our upper management: to establish a forward-thinking, deep-rooted desire in our staff to protect themselves, our subcontractors, and the communities in which we work.

To facilitate this mentality of care, all of our staff has now been fully trained in the STOP Program, which seeks to encourage safe behavior in positive, non-punitive ways. Additionally, our project management team has been trained in a variety of job specific disciplines including CPR + First Aid, Trenching & Excavation, Fall Protection, Forklift, Confined Spaces, MSHA, and OSHA. Chris conducts weekly site visits to assess working conditions, meeting with subcontractors when necessary to encourage improvements, and stopping work if a given situation is found to be below our standards. Our Superintendents also participate in these efforts by ensuring daily compliance with PPE requirements, conducting Toolbox Talks, and performing regular Job Hazard Analyses. Our management team has also implemented a Lessons Learned process after the completion of each job to discuss how we can work better and safer in the future.

Our founder’s people-oriented mentality fortifies the hiring of qualified, safety-minded personnel who will add to our company ethos. With this mind, during the hiring process, we look for candidates who value safety and who seek to perform their duties with a mind for hazard avoidance. We have held Colorado Cost Containment certification since 2008, documenting that our company has maintained a qualified risk management program. We intend to continually improve our safety program as we seek to prevent hazards from ever happening, and construct in an efficient yet safety-conscious manner.

We appreciate the efforts of all our team members—and subcontractors—who intentionally add to our efforts to protect ourselves and others. You are the reason we are in business and will continue to build safely along the Front Range for years to come!

Let’s celebrate our new hires!

We are thrilled to welcome a new senior accountant, Mark Lutz, who started in July. He has experience establishing and implementing not only accounting policies, but also safety and security policies, procedures, and controls. Mark has successfully opened three luxury hotels and has managed all aspects of the Finance department. As a previous Director of Finance, he even successfully transitioned a hotel to a new ownership/management company providing training and support along the way.

Before entering the business world, Mark was a junior high teacher and coached baseball.

Mark now enjoys his off time in the outdoors whether it be hiking or snowshoeing with his family or fly fishing in the high-country lakes.

As we go through a few transitions, we are eager to see his knowledge and experience make a big impact and bring us to the next level - Welcome to the team, Mark!


Second, David Hollerbach has made an exciting return to Hall-Irwin as our new senior project manager. He brings back with him, 30 years of experience in construction in vertical building projects, 8 of which, were as a project manager for Hall-Irwin.

David was lucky enough to have an idyllic childhood. Growing up in Lake Tahoe in the 60’s and 70’s, much of his time was spent left to his own devices with his friends, enjoying all the activities and beauty that the mountains and lake had to offer.

David now has a passionate relationship with construction and has taken on the task of remodeling and building an addition to his 1910 farmhouse which was located on two properties and within a setback. The work first required merging of the two properties and obtaining a variance before any construction could begin.

We are very thrilled to have him rejoin Hall-Irwin with the knowledge he has acquired in the time he has been with other companies. Welcome back David H!


Third, why stop at one David, when you can have TWO? David Zeigler has also joined the Hall-Irwin team in July. His contribution as one of our superintendents adds to our "boots-on-the-ground" team. David brings 25 years of land development experience with him.

David's free time is happily made up of having two daughters - ages 12 and 19. His oldest has a passion for horses and competes in Barrel racing events all over the country while his youngest is active in sports and is developing her passions in life.

David personally enjoys golfing, sportfishing and is a master on the BBQ. A fun random fact about David, is that he is a huge football fan! One weekend many years ago he and some friends rushed to California in support of a slow white Bronco with OJ Simpson in the back; they actually made it to his house.

Welcome onboard David Z!


Our latest new hire, Jason Donley, also joined our team at the end of July. He has complimented our preconstruction team as our new estimator with extensive experience in vertical construction estimation. Growing up in Ohio, he began his career in construction. Jason moved to Larimer, Wyoming growing his strengths in estimating eventually bringing them to Colorado and to Hall-Irwin.

In Jason's free time, he prefers either fixing things or exploring the great outdoors with his wife. Being new to Colorado, he is excited to explore new hiking trails, campgrounds, fishing holes, hunting grounds, and whatever Colorado outdoors may bring.

Welcome to Hall-Irwin and Colorado, Jason!

Take time to say hello to our new team members when you get a chance!

This is the 6th year in a row that Hall-Irwin has participated in the Compete to Beat Hunger Food Drive for our local food bank, Weld County Food Bank. It is a fun event that gives us another chance to give back to our community. We participated in several events this year.

Bri, our marketing manager, volunteered on a hot Friday at the mobile food pantry in Evans,

CO. This was the first mobile pantry that Hall-Irwin had volunteered at! With inflation still raising, more and more families are needed help with obtaining basic food essentials. Watermelon, onions, corn, cucumbers, grapes, apples, and milk were all distributed at this event.

Another new event for Hall-Irwin to participate in was the CanSculpture contest. After voting on 6 different CanSculpture ideas, the creation of the Kersey Town Hall was rated number one!

A little background about the Kersey Town Hall Project:

The Town of Kersey had outgrown its' library and current Town Hall and needed to find a solution. A historic structure downtown, known as the "Kersey Co-op" building, became available and the Town began working with the University of Colorado Denver's Urban Technical Assistance program to find out how to best use it. The Town Center project was created and the Town of Kersey needed a contractor to help bring the new project to life. Hall-Irwin entered into another design-build agreement with the Town to rehabilitate the historic building while bringing it up to a green energy standard. The facility is now able to hold Council Chambers, Community Meeting Spaces, Office Spaces, and the Police Department.

It was a fun first build and we are proud of the results. We donated 745 pounds of food and collected $1,618.72 in cash. Combined, we helped the Weld Food Bank provide 5,750 meals.

Check back next year for the next contest!
