Utility Trench Engineering for Electrical Conduits

I need an experienced engineer to design the construction of a utility trench for electrical conduits. The trench will be located in an industrial site and will be 3' deep and only 220 feet long. Also there is a fiber optic trench approx 75' long and 2' feet deep . I believe this is called Duct Bank Engineering Key Requirements: - Design a safe and efficient trench layout - Ensure compliance with industrial safety regulations Ideal Skills and Experience: - Engineering background with experience in utility trench projects - Knowledge of electrical conduit installation - Experience working in industrial environments Looking forward to your expertise on this project!
