SP for Drilled Shafts Section VII.3. Wet Construction Method and 5. Permanent Casing Construction Method are contradictory and require clarification. Paragraph 3 states “The wet construction method may be used in combination with the dry method and temporary or permanent casing methods.” Paragraph 5 appears to preclude the use of wet construction for permanent casing installation. Please confirm that the installation of the permanent 36 inch casing in a 36 inch slurry filled hole is allowed as stated in Paragraph 3.
