Casing. Use casings if the elevation of the top of the caissons is at or below the ground or expected high water elevation at any time during construction. If casings are used, set the elevation at the top of the casing a minimum of 2 feet (600 mm) above the ground or 4 feet (1200 mm) above the expected high water elevation at the site, whichever is greater. Cut off any permanent casing used as shown on the Plans. Use casing that is a metal shell of a thickness to withstand handling, internal and external pressures, and that is watertight, smooth and clean. If the elevation of the top of the caisson is below ground level or water level at the time of concrete placement, use an oversize casing from ground elevation to a point below the top of the caisson to prevent soil from caving into the fresh concrete. Do not allow the top of the permanent casing, if required, to extend above the top of the drilled caisson. Use casing in all materials that do not have sufficient strength to safely remain open and stable during and after excavation. When casing is used, do not use casing with an outside diameter less than the specified diameter of the caisson. That portion of the caisson below the casing may be slightly smaller than the normal outside diameter of the caisson. However, use drilling tools to excavate the caisson below the casing that are no smaller than the Plan diameter of the caisson minus 2 inches (50 mm). Do not leave casing in place unless permitted by the Engineer, and cut off any permanent casing as shown on the Plans. Provide adequate equipment during concrete placement to prevent pulling up the reinforcing cage during casing extraction. The casing may be pulled in partial stages. Maintain a sufficient head of concrete above the bottom of the casing to overcome hydrostatic pressure. Extract the casing at a slow uniform rate with pull in line with the center of the caisson. In open-water locations, provide containment at the top of the casing to prevent any material from spilling into the water. Install casing to a depth and in a manner that will produce a positive seal at the bottom of the casing. Do not allow water or other materials, into or out of the excavation area at or below the bottom of the casing. Do not leave casings in place unless permitted by the Engineer. If casings that are to be removed become bound in the caisson excavation and cannot be practically removed, or if the permanent casing is lowered below the proposed tip elevation, drill the...

Casing. Use casing that is a metal shell of a thickness to withstand handling, internal and external pressures, and that is smooth and clean. Use casing in all materials that do not have sufficient strength to safely remain open and stable during and after excavation. Extract the casing at a slow uniform rate with pull in line with the center of the Compacted Aggregate Pier.
Casing. The casing must be securely attached to the book block. The casing must contain a heavy 90# Kraft back line on the spine area. The boards must be Davey Red Label Binder's Board with .097" thickness or an equivalent board as approved by the Agency. The end sheets must be heavy weight. The spine must be loose and rounded. The joints must be uniform and tight and the casing must include adequate gutters.
Casing a. Sinking: Casing shall be driven vertically through earth or other materials to such depth below the surface of the ground as required to maintain the sides of bore holes or as directed by the Engineer. The blows per foot required for the penetration of the casing shall be recorded and included in the Contractor's drill record. Simultaneous washing and driving of the casing will not be permitted, except by order of the Engineer, and where so permitted, the elevations between where water was used in driving the casing must be recorded. It is the Contractor's responsibility when boulders or other obstacles are encountered to carry the drilling through or past such obstacles.
