Maximum weights are 100 pounds, with 50% greater than 50 pounds.

Stone gradation shall be based on a representative sample of not less than 10.0 cubic yards. Each stone in the sample shall be individually weighed/measured, and a cumulative plot of percent lighter (by weight) versus stone weight in pounds shall be submitted. The CONTRACTOR shall also select ten (10) representative armor stones from the quarry and have each stone weighed. Each weighted stone shall be clearly marked with its weight. The weighted stones that meet the specifications shall be placed in a convenient location in the quarry where the CONTRACTOR can compare future selected stones for possible shipment to the project site.

14.3 Armor Stone Unit Weight. The CONTRACTOR shall provide certified results of laboratory testing conducted by an independent lab to determine the unit weight and specific gravity of the stone. Tests shall be conducted within 90 days of the start of construction. The tests shall be conducted on a minimum of ten (10) samples randomly selected from the quarry proposed for use. The test shall be ASTM C127. The minimum unit weight of the armor stone is 140 pcf (saturated, surface dried) and the minimum specific gravity shall be 2.24. All 10 samples shall meet or exceed these minimum

TS-13

standards. Failure of the test on the first set of 10 samples and a following set of 10 samples will be cause for rejection of the quarry and/or quarrying process. Stones that fail the test shall not be incorporated into the WORK. The initial test and any additional test required because of failure of the initial test sample will be made at no cost to the COUNTY. The CONTRACTOR may not use more than one quarry without prior approval of the ENGINEER. The ENGINEER will require additional tests, at no expense to the COUNTY, if additional quarries are requested.

23 ARMOR STONE INSTALLATION.

23.2 Armor Stone. Armor stones of the quality and size specified shall be placed in such a manner so as to minimize the void spaces between the stones. The finished surface shall be relatively uniform and shall contain the maximum amount of armor stone as can be obtained by performing the WORK as specified. The structures shall be constructed to the lines and grades shown on the drawings. Stones shall be individually placed in a manner that will prevent rolling or sliding of stone down the slope. Armor stones should be oriented with the longest dimension perpendicular to the structure's alignment, where possible. The stones shall be placed within the boundary of the foundation and not overhang or contact the ground surface. Placing the armor stone by dumping into chutes or by similar methods will not be permitted.

23.2.3 Armor stone shall be placed so as to be in contact with adjacent stones and should interlock to form a compact stable mass. Chinking the voids is not permitted.

Both during construction and upon completion, the structure will be inspected for conformance to the design. The COUNTY will not pay for any stone misplaced or lost during placement.

23.2.4 Placement of stone material during periods of wave energy sufficient to cause displacement of material shall be at the CONTRACTOR's risk. All materials lost or displaced during construction as a result of wave displacement shall be replaced at the CONTRACTOR's expense.

23.3 Tolerances. A vertical tolerance of ± 0.5 feet to the design surface of the revetment crest shall be permitted for projections and depressions of the in-place material. A horizontal tolerance of ± 1.0 feet to the design footprint of the revetment toe shall be permitted for projections and depressions of the in-place material. Placed material that is beyond the maximum tolerance stated herein is ineligible for payment. The ENGINEER may request any stone that exceeds the tolerances be removed by CONTRACTOR at the CONTRACTOR’S expense.

23.4 Bid Tonnage. The tonnage of armor stone in the bid assumes that there are no voids and accounts for zero tolerance. Unless changed by the ENGINEER, the bid tonnage is the maximum pay tonnage. The CONTRACTOR shall make his own estimate prior to

TS-17

making his bid. The bid tonnage assumes 140 pcf stone is used to fill the template. If a higher unit weight stone is used, it is possible that the final elevation of the structures will be between the lower tolerance and the template. Regardless of the stone density, the minimum tolerances shall be met.

23.5 Test Section. At the start of the work, the CONTRACTOR shall complete a 50-foot test section of the first revetment section under construction prior to performing WORK on other sections of the revetment. The CONTRACTOR shall notify the ENGINEER that the test section is complete and shall submit a survey consisting of at least two cross-sections to the ENGINEER. The ENGINEER may observe the section to determine compliance with the construction Plans and Specifications. The CONTRACTOR may continue construction of the structure prior to the ENGINEER’s written approval of the test section; however, materials placed prior to the ENGINEER’s approval of the test section are subject to remediation at the CONTRACTOR’s own risk and cost.

23.6 Basis of Payment. The stone will be paid for at the in-place contract unit price per tons of armor stone. Payment shall be based upon the per unit items constructed by the CONTRACTOR and accepted by the ENGINEER on the basis of both suitable documentation provided and observation of the WORK. Documentation of the WORK shall include the survey of the completed work and a certified weight determination of the quantity of material delivered to the site and placed within the lines and grades as described in these Plans and Specifications. Stone shall be measured by the ton, saturated surface-dry. Measurement shall be by railroad scales, truck scales, barge displacement, volume measurements or other method approved by the ENGINEER. The ENGINEER shall approve which of the methods, i.e. railroad scales, truck scales, barge displacement, or volume measurements, is to be used. Duplicates of the sworn certifications of weight shall be furnished with each load of material and presented to the job inspector/superintendent for their signature. Certificates of weight, which do not bear the signature of the job inspector/superintendent, will not be considered for payment. The WORK specified under this Section, upon acceptance by the ENGINEER, shall be paid for under the Bid Item “FURNISH AND INSTALL

ARMORSTONE”.
