Making underground collection & sitework a breeze!

Over the years here at H.L. Chapman, we have performed trenching for a multitude of underground collection systems on both solar and wind projects.  With a wide variety of machine sizes, we can handle all your trenching needs for both AC & DC collection utilizing single cut widths from 15” up to 60” wide.  Our milling machines are the perfect fit for removing the rock from your substation pads or access roads as well.  Contact us below for all your renewable project trenching and excavation needs.
