  • The level of detail provided to us was the best set of coordination drawings I have ever worked with. All the problems with ceiling, curbs and steel details to deal with, their coordination drawings helped correctly identify and fix the problems so we would not have any problems or conflicts with any of the work, as a result of their level of detail.
