Section 6.01, Item 44
Enquiry
Section 6.01 of the Special Provision for item 44 requires that the lead end of the auger be kept at least one casing diameter behind the end of the casing. This soil plug will prevent the casing from being steered and preclude access to the end of the casing to remove boulders. In addition, the boreholes indicate that jacking the casing in these conditions is unlikely to be feasible and, if successful, would likely result in heave of the pavement. Please clarify how the soil plug is to be dealt with.
