J.M. Construction, Inc. - Contact Us. At JM Construction we are committed to being mobile so that we can spend more time at our projects and less time in the office. With this philosophy we have been able to dedicate more time to our customers and their projects and less time and money on overhead and supervision. We are owners that spend more time at each project then we do in the office. Since 2008 we have been moving from the traditional centralized office staff construction model to a mobile model. We are dedicated to reducing our overhead while maintaining the highest levels of communication and excellence. We have been able to accomplish that, since 2008, with better then expected results and we are excited to see what the future will bring.
