We were particularly impressed with your firms’ commitment to safety and thoughtful pre-planning efforts. As an outcome, there were no recorded injuries during your phase of work and the work was completed ahead of schedule.

I also want to compliment Konell on its excellent recycling results. Recycling results in excess of 95% in demolition work is an impressive accomplishment.

They all exemplify the true meaning of the words “partner” and “teamwork,” which are invaluable attributes to possess as contractors. The most notable differentiating factors that I have observed about Konell Construction are that they are solution-oriented in how they approach project challenges and that they approach every project relationship with the highest marks of honesty, integrity and professionalism. I have yet to meet anyone at any level of Konell Construction that does not exemplify those same attributes that make them such a pleasure to work with.

I am happy to say that in the 30 years of experience I have here at Hoffman, I can honestly say that Konell comes with the highest recommendation I can give. From their preconstruction efforts to work performance and overall project management approach, I have not worked with a better firm. We are happy to say that Konell delivered their scope of work ahead of schedule and on a budget. I do not think we would have made the aggressive schedule without their efforts.
