The unit price shall include all the labor, materials, equipment, and incidentals necessary for loading, hauling, weighing, and stockpiling or placing the designated quantities of materials denoted on the line items.

5. Rock Sources

a. General. Gravel, and 1- to 4-inch material shall be obtained from a quarry. The limits of excavation shown on the quarry drawings supplied with contract depicts the Government’s estimate of the volume of materials needed to excavate and process to obtain the material quantities. The Contractor shall develop the quarry’s area, as shown on the drawings, to produce the materials required by the contract unless an alternate area is approved by the Contracting Officer. The actual volume of materials required for excavation and processing to obtain the required quantities of gravel, and 1- to 4-inch material may vary from the limits of excavation shown on the drawings due to the nature of the materials encountered.

The sole purpose of the quarry drawings is to show the location of the quarry and where past work has occurred. It is the contractor’s responsibility to visit the quarry locations to determine the complexity of the work and site working conditions. The contractor will be responsible for determining what area within designated quarry limits will produce the quantity and type of material required for the contract.

The Contractor is responsible for any conclusions as to the nature of the materials to be quarried and the difficulties of performing the quarrying operations. Approval of a deposit (the actual location of the rock as shown on the site plan provided by BOR) is not an approval of all materials taken from the deposit. The Contractor shall be responsible for the specified quality of all such materials used in the work. No payment will be made for any material which does not meet the specification requirements.

The Government reserves the right to change the limits of the work area in the Contractor’s quarrying operations within the general riprap source area in order to obtain suitable materials.

b. Quarry operation. Maintain access roads within the quarry as required for your operations. During the quarrying operation, the height of the working face may exceed 40 feet.

Excess, stripped material, and material that doesn’t meet the specifications remains the property of the BOR. Dispose of waste material in existing small washes at the quarry site, in locations designated by the Contracting Officer. Waste materials shall be graded to a generally uniform surface to blend with adjacent ground surfaces. All suitable material produced in excess of that required shall be left in stockpiles at the quarry site.

c. The Contractor will be responsible for obtaining all of the necessary permits including the ADEQ requirements as determined by the individual management districts.

The Contractor shall notify the appropriate district manager of Mine Safety and Health Administration (MSHA), in accordance with 30 CFR 56.1000, before commencing quarry operations falling within the jurisdiction of MSHA. In the event of conflict between any safety requirement of the Department of Labor and BOR’s Reclamation Safety and Health Standards, the more stringent requirement will prevail.

d. Quote Prices. The cost of reducing any oversized material (existing and produced during the quarrying operations) to designated size, maintaining access roads in the quarry, and adhering to the safety requirements shall be included in the respective unit prices per ton quote in the schedule for processing gravel base and 1- to 4-inch materials.

6. Gravel Base and 1- To 4-Inch Material Source

a. General. Material for the gravel base and 1- to 4-inch stockpile shall be obtained by the Contractor by processing quarry material, including existing material remaining from previous quarry operations. The Contractor’s operation at the material source shall be such as shall result in the best practicable production of the required material and shall at all-time be subject to the approval of the Contracting Officer. The Contractor assumes all responsibility for any conclusions as to the nature of the material to be excavated and the difficulties of the excavation.

Gravel may be the result of sieving or may be 1- to 4-inch material processed through a rock crusher. The means proposed for the production of the material will be shown on the contract.

Approval of a deposit is not an approval of all materials taken from the deposit. The Contractor shall be responsible for the specified quality of all such materials used in the work. No payment will be made for any material which does not meet the specification requirements.

b. Costs. The cost of processing and/or development of gravel sources shall be included in the unit price per ton quote in the schedule for processing of gravel base per the requirements of paragraph 3 (Measurement and Payment for Processing Gravel Base Material). Contractor may seek approval from the Contracting Officer to furnish gravel from sources other than from the quarry designated in the SOW, or from other commercial suppliers as long as the Contractor pays all royalties or other charges required for these materials and the delivered per ton cost does not exceed the cost excavating, processing, loading, weighing, hauling and stockpiling the material from the designated material site.

7. Gravel Stockpile

a. General. The Contractor shall place gravel at the stockpile site(s) designated. The gravel used shall be material obtained from the approved source in accordance with Section 5 (Rock Sources) or 6 (Gravel Base and 1- to 4-Inch Material Sources.)
