Our team can economically route and design any aerial/underground transmission routing through various types of terrain or right of way limitations. From 69 kV to 500 kV, we have the expertise to meet our client’s needs and expectations. PDS uses PLS-CADD software to create and design our transmission line models. We can create terrain models using survey data from simple paper contours to complex digital LiDAR data. Need a transmission line rating for NERC compliance? We can provide turnkey services or just the engineering reports.
