Appendix C Quarry Demonstration Form
Quarry Name Minimum Quarry Supply (tons/yr)1
I certify that I have investigated the above quarries sufficiently to determine that the quarry stone meets specifications, that the tabulated minimum stone supply from each quarry (tons/yr) is feasible, and that I am confident the total capability of all tabulated quarries equals or exceeds the minimum required supply of 170,000 tons/yr.
Contractor’s Designated Signatory _____________________________________
1 – While use of the listed quarry and the minimum supply quantity (tons/yr) for each quarry is not contractually binding, the tabulated value represents due diligence on the part of the Contractor to accurately assess quarry quality and capability.
