Caisson Rock Sample Clauses

The Caisson Rock clause defines the responsibilities and procedures related to encountering rock formations during caisson drilling operations. Typically, it outlines how the presence of rock is identified, the process for measuring the depth or volume of rock encountered, and the method for compensating the contractor for additional work or equipment required to drill through rock. This clause ensures that both parties understand how unforeseen subsurface conditions, specifically hard rock, are managed and compensated, thereby allocating risk and preventing disputes over extra costs or delays.
Caisson Rock. Caisson Rock is defined as material that must be removed from a shaft which cannot be penetrated faster than two feet per hour (fifteen minute minimum) using a rock auger with bullet-shaped hardened steel teeth (Kennametal bits or equivalent), and the drilling equipment should have the capacity to produce a continuous torque of at least 1,000,000 inch pounds and a downward force of at least 50,000 pounds (a ▇▇▇▇▇▇ LLDH in good working condition) for piers up to seventy two inches in diameter. Use of equipment with greater torque or downward force modifies the definition of refusal to be the point at which the equipment cannot penetrate faster than two feet per hour (fifteen minute minimum). In rare cases, refusal may occur on a rock seam or boulder above the general massive rock surface. The compensation for Caisson Rock should include only material that cannot be penetrated by the rock auger at the specified rate.
