Whether you need expert design of low-profile steel switch stands and foundations capable of withstanding hurricane force loads, or a maintenance access road crossing a wetland; you can count on Pickett and our client focused team of professionals to provide the deliverables you need to get the job done right.
Major water crossings, mountainous terrain, urban centers, and coastal areas all provide their own unique challenges with comprehensive environmental permitting, construction planning, and coordination with various agencies. Equipped with the latest in technology and decades of experience our clients rely on us to solve their complex engineering problems.
Pickett leads the industry with skilled engineers seasoned with extensive experience. Representative projects in our portfolio include a five (5) mile water crossing composed of direct buried concrete structures and another five (5) mile water crossing consisting of pile-supported steel H-frames.
Pickett’s senior engineering staff has modeled and analyzed over 10,000 miles of transmission lines for NERC FAC-008 and 003 compliance for multiple utilities throughout the Mid-Atlantic and the Southeast. This has allowed us to become industry leaders in the use of PLS-CADD finite element modeling and wire temperature determination for facilities ratings.
We have redefined the as-built process to deliver the most accurate as-built models, by mastering techniques using various finite element fit modes available in PLS-CADD. Using LiDAR acquired and processed by our own team of aerial and LiDAR professionals, we verify the installed sag and tensions. Weather data and line loading information determine the temperature of the wire for accurate tension determination.
Pickett’s engineers deal with existing steel lattice towers every day. With structural analysis and modeling using PLS-Tower, we can confidently move forward with overhead ground wire replacement, re-rates, telecom antenna installations and other projects.
