3. Q: Are there special containment and disposal requirements for drill cuttings, waste grout, and drilling spoils?
a. A: The contractor is responsible to prevent the contamination of any stream or groundwater source. All drill cuttings, excess drilling fluid, grout, or any fluid containing foreign substances shall be contained and shall be prevented from entering any watercourse. All spoils, drilling fluid, and waste grout shall be removed from the project site in accordance with applicable laws and regulations.
4. Q: Would it be allowable to pump water from Red Run to use in drilling operations?

Compressive Strength for the proposed mix design is to be tested prior to producing grout. Grout is to be sampled to test compressive strength, density, and flow when the grout is placed. Density and flow are to be sampled for and tested once per 5 piles. 1 set of 3 samples are to be taken and tested for every five micropiles or from each grout plant per day of operation, whichever occurs more frequently.
9. Q: Is a micropile design required as part of the project work?
