Anning-Johnson Company was extremely thorough in reviewing, understanding, and executing the details of the job. They were highly active in coordinating and collaborating their work with all the other trades preventing the potential for rework. It was awesome to see their dedication, collaborative approach, and execution of a complex fast-paced project.
