I manage construction projects across the United States for our company’s multi-billion dollar infrastructure, select contractors to complete these projects, and manage all aspects in between. During the past 8 years, I have worked with Zoellner Construction Co, Inc. on several large projects for Frac Tech. Projects range from warehouses, offices, process equipment, excavation, and steel erection including locations in: Missouri, North Dakota, Texas, and Pennsylvania. Projects range in size from $1 to $20 million. When I have a project, Zoellner Construction is the first one I call to get pricing, advice, or to get a job done quickly. Approximately 50% of the projects Zoellner does for FTSI are Cost plus Fee type projects. When Zoellner is awarded one of my projects, I know I will have more time for other important things. Zoellner is the type of contractor that I can just let them do what they do best, which is getting a quality job done on time and under budget. Zoellner jobs run smoothly and when issues arise they already have suggestions to a solution and an opinion on cost efficiency. I hope this letter relays my message that Zoellner Construction truly is “Excellence at Work”. Sincerely, Coy ...

We submit this letter of recognition for Ronnie Oehl, Foreman for Zoellner Construction, for his performance of the A.C. Brase Arena Renovation. Ronnie was a major factor in the success of our project not only with his own duties but also with all of the day-to-day coordination for all other contractors. Ronnie always maintained a very professional demeanor with all contractors as well as with all of our staff customers. He was always very conscientious of our programs & our facility events. Ronnie has excellent communication skills as well as a very friendly and business-like demeanor. He kept our staff up-to-date on the various projects and responded to our needs in a very timely manner. You should be proud to have such a quality employee. Ronnie became part of our extended family. We will all miss him and look forward to working with him again. We would also like to commend two other employees who were a major part of this project, Larry Brewer and Willie Kester. Their performances over the 5 months were exceptional. They are quality employees and we were very pleased with all of their work. Sincerely, Dan Muser, Director & Scott Williams, Recreation Division Manager

During the past nine years, I have worked with Zoellner Construction Co., Inc. on several large projects for the university, including: Renovation of the Perryville Higher Education Center, renovation of Towers South & Towers East dormitories (12 floors), construction of a riverfront park with walking trails, signage, and a gazebo, renovation of 3 chemistry laboratories, renovation of 2 physics laboratories and an equipment room, installation of fire sprinklers, fire alarm, lighting, and ceilings in Myers Hall, a five-floor dormitory, and construction of a new 11,500 SF building for the treatment of autism. The work included all disciplines of construction: demolition, grading, carpentry, electrical, mechanical, plumbing, landscaping, etc. When Zoellner is awarded one of my projects, it gives me a sense of relief because I know that the project will be run smoothly. I know that the project will be done on schedule and that on any issues that are encountered during construction, they will work with the university to suggest solutions that are viable and economically feasible. I anticipate using them to complete many future projects and am hopeful that they choose to continue their working relationship with the university. Sincerely, Lisa A. Howe, Senior Project Manager Facilities Management
