As neighbors of the Ford City water plant project we until now have been very happy with the handling of the construction you have been doing- that is until now when you have begun demolition of the old plant & have begun jack hammering at 7am waking up all of our small children. While we know the urgency to get the building down 7am is a bit extreme. I can send you a video of the sound from our front porch. Poorly handled with little consideration of the neighbors who have been very cooperative during your construction.

Involved in a road road incident with them. Their driver cut me off, then after laying on my horn so they didn't hit me, proceeded to get out of their car, attempt to start a fight and ride my ass the rest of the way down 51. If this is how their employees handle themselves on the road in company vehicles, I couldn't imagine hiring them for a job.

Absolutely the worst company I have ever dealt with. Horrible communication from start to end. Took forever to have a simple project completed. Would not recommend. I am at loss at how they remain in business.
