Tunneling and Trenchless

Tunneling and Trenchless

Our tunneling and trenchless solutions enable us to facilitate infrastructure projects where conventional, open cut methods would disrupt constituents’ quality of life, require lengthy permitting reviews, or would be too expensive. From trenchless road or railway crossings for water lines involving horizontal auger boring or horizontal directional drilling to deep gravity tunnels for stormwater and wastewater involving tunneling or microtunneling boring machines, Freese and Nichols tailors this specialized service to meet your needs for projects of all sizes.
