“Tim did a great job synchronizing his structural plans with the architectural plans on my complex residential project. With both the structural engineer and the architect using Revit as their design program we did not have any mistakes with dimensions or cross sections. Tim is also easy to get a hold of from the field if I have questions that need quick responses.”

-Mark Jordan
