Enquiry
Table 1 of the Guideline for Foundation Engineering – Tunnelling Specialty for Corridor Encroachment Permit Application, indicates for tunnel diameters between 300 mm and 1000 mm, where the depth of cover is 3 times the tunnel diameter and at least 1.5 m, the complexity rating is Medium for 400 Series Highways. Based on a review of the RCD the largest diameter utility to be relocated is 650 mm. Considering this information, please provide the rationale for the High Complexity Tunnel specialty registration for this project.

Response
The requirement for RAQS Tunnelling – High Complexity shall be maintained for the following reasons: • Trenchless crossings under KWE (a controlled access highway) may involve larger excavation diameters for multiple pipes and/or larger diameter casing (e.g., for a 650 mm Ø utility pipe, a casing with Ø > 1000 mm may be required). • Relocations of sewers and watermains are proposed near the Frederick Street bridge structure abutments and foundations.
