• Differing Site Conditions: For pricing Contract Line Item #3, potential unknown problems causing leaks should reference FAR clause 52.236-2, Differing Site Conditions.
• Dam Safety Review: Dam Safety will review the Contractor's work plan to ensure adherence to the approved Drilling and Invasive Program Plan (DIPP). Any deviations require Dam Safety vetting.
