3.3.2. Placement. Stone for riprap shall be placed on the bedding layer in such manner as to produce a reasonably well graded mass of rock with the minimum practicable percentage of voids, and shall be constructed within the specified tolerance to the line and grades shown on the drawings issued with delivery orders. Riprap shall be placed to its full course thickness at one operation and in such a manner as to avoid displacing the bedding material. Placement shall begin at the lower elevations and proceed up the slope. The larger stones shall be well distributed and the entire mass of stones in their final position shall be roughly graded to conform to the gradation specified in SECTION 2D, 3.3.1. The finished riprap shall be free from objectionable pockets of small stones and clusters of larger stones. Placing riprap by dumping into chutes or by similar methods likely to cause segregation of the various sizes will not be permitted. The desired distribution of the various sizes of stones throughout the mass shall be obtained by selective loading of the material at the quarry or other source; by controlled dumping of successive loads during final placing, or by other methods of placement, which produced the specified results. Rearranging of individual stones by mechanical equipment or by hand will be required to the extent necessary to obtain a reasonably well-graded distribution of stone size as specified above. The Contractor shall maintain the riprap protection until accepted and any material displaced by any cause shall be replaced at his expense to the line and grades shown on delivery order drawings.

3.4. Foundation Preparation. The areas on which bedding layers is to be placed shall be trimmed and dressed to conform to the cross sections shown on delivery order drawings. Where required, the foundation area shall be cleared as specified in SECTION 2A, CLEARING AND GRUBBING. In foundation areas requiring fill, the foundation area shall be filled, graded and compacted as specified in

SECTION 2B EARTHWORK.

3.5. Breakwater Construction. Breakwater construction shall be at the location shown on delivery order drawing. The construction of the breakwater shall conform to the lines and grades indicated on these drawings. Stone for the breakwater shall conform to the gradation requirements of SECTION 2D; 3.3.1 for 500-pound and 150-pound topsize stone and shall meet the requirements of SECTION 2D, 3.1 regarding stone quality. The breakwater shall be constructed by dumping ahead of stone within the limits of the location of the proposed breakwater to form a working platform above the lakes water elevation as described on delivery order drawings. Construction of the working platform shall be continued until a platform has been formed along the entire length of the proposed breakwater to an elevation not more than two (2) feet above the elevation as shown on delivery order drawings.

4. MEASUREMENT AND PAYMENT. Bedding material, riprap, and ditch aggregate will be measured for payment by the ton (2,000 lbs.). Stone used in the construction of the breakwater will be paid for as Riprap Stone. Payment for the placement of riprap will be made at the contract unit price per ton of “ Bedding Material”, “Riprap Placement, 400 pound top size”, “ Riprap Placement, 150 pound top size”, and “Ditch Aggregate, (8-inch maximum)” and placed North of Bruce Findlay Road or South of Bruce Findlay Road.

Prices and payments shall constitute full compensation for all labor, materials, equipment, and supplies and performing all operations necessary for the delivery and placement of bedding material, riprap and ditch aggregate.
