They were able to add both value and cost savings to the project that were significant to the completion of the project.  Mr. Wellmon was able to meet deadlines and effectively manage several sub-contractors to complete the administration building within the project deadline and budget. Mr. Grelle was both very organized and his attention to detail invaluable. With his recommendation of the post-tension slab, we were able to construct a better building with little impact to the project budget. Construction Concepts is one of the best construction companies that I have dealt with and I would highly recommend them for future construction projects.

Construction Concepts has worked on the Auraria campus for over two years on a variety of remodel projects as both a general contractor and as support service on our tenant finish projects. Construction Concepts has shown, on many occasions the flexibility to work within our campus schedule of classes, and have continually performed at a high level of competence on all of the projects.

Doug McLean, Construction Manager – Auraria Higher Education Center

Throughout the project Construction Concepts met with our staff weekly in the early stages of the construction then often made construction recommendations resulting in change orders which saved the District money. We are very pleased with the quality of work and the quality of service provided by Construction Concepts. As Fire Chief, I found them to be very easy to work with.

Construction Concepts displayed integrity and organization through the entire process and helped direct our design team to keep the project activities and costs in line. There were several challenges with our project as it related to weather, site work, equipment procurement, and building design and the team at Construction Concepts were instrumental in solving all of them. Finally, without hesitation I recommend Construction Concepts for the construction of any construction project. I am confident you will find that they are an asset to your project and you can be assured that their level of integrity is top drawer.

Your group of sub-contractors met the construction schedule, completed the necessary weekly updates and milestone submittals, kept the change orders to the bare minimum and only when truly necessary; the site superintendent was always professional and accessible.

Through Dan’s leadership, diligence, and preparation we were able to start construction the day after closing and completed a major renovation of all systems and finishes for an open house reception on December 15th 2009. I am honored to call Dan a true friend and commend his ability to handle stress and manage the stress of his clients during the difficult process of transformation called construction. With his exemplary skills and passion for his business I proudly recommend Dan for any project where one seeks high attention to detail and an unwavering dedication to completing a job to the customer’s complete satisfaction.

I have had the pleasure to work with Dan Grelle in the design and construction of my medical office. Dan did a great job in planning and execution of the project. Dan was also very diligent with regard to budgeting. He was cost conscious when possible and was very pragmatic with expenses. Finally, I have nothing but good things to say about the people who work for Dan Grelle. They consistently showed high regard to customer service and were a pleasure to work with.

We were pleasantly pleased with the timeliness and accuracy of the project. However, the big plus we experienced when working with this organization was the ambient level of integrity which we consistently encountered throughout the project.
