“3.2 RIPRAP PLACEMENT

a. Riprap shall be placed within the limits shown on the drawings.

Riprap stone shall be placed in such manner as to produce a reasonably well-graded mass of rock with the minimum practicable percentage of voids.

b. The placement area shall be free of objectionable material such as tree snags and root wads prior to placement.

c. Riprap shall be placed to its full course thickness in one operation and in such manner as to avoid damage to the bedding material and to minimize segregation of the riprap. Stones shall be selected and keyed in, meaning that stones are set in contact with each other so that the interstices between adjacent stones shall be as small as the character of the stone will permit. All faces of the set armor stone shall be touching adjacent armor stones. Each armor stone shall not rock in place. The maximum dimension for void space between adjacent stones shall be 12" in any dimension in a horizontal plane and not more than the depth of one armor stone layer vertically, unless otherwise accepted by the Contracting Officer. The face of stone having the largest area shall be placed against the surface of the underlying material. 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. The finished riprap shall be free from objectionable pockets of small stones and clusters of larger stones. Placing riprap in layers 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.

d. All stone shall be placed by clam, orange peel or skip box. Maximum drop height shall be zero for stone placed above the water surface, and three feet above the final resting place for stone placed below the water surface. Whatever method is proposed, the contractor shall demonstrate placement to the satisfaction of the Contracting Officer.

e. A tolerance of plus or minus one-half foot will be allowed on the prescribed structure elevations.

f. The side slopes shall be determined by the natural angle of repose of the stone, varying from 1v on 1.25H to 1v on 1.5H, except where specified in the contract drawings. Dumping of stone at the top of slopes and rolling or pushing into place will not be permitted.

g. Manipulating or moving stone at any time prior to placement by means of dozers or other blade equipment will not be permitted. Rearranging of individual stone by mechanical equipment or by hand will be required to the extent necessary to obtain an interlocked and well-graded distribution of stone sizes as specified above.”

b. Specifications (New and/or Revised and Reissued). Delete and substitute or add specification pages or sections as noted below. The substituted pages or sections are revised and reissued with this amendment.
