CAP Rathbun Shoreline Rock Purchase

Page 1 SECTION 35 31 19 PART 1 GENERAL STONE PROTECTION 01/08 Processing, testing, hauling, and stockpiling stone shall meet the requirements of the contract documents. All supplied stone shall be from Corps of Engineers approved sources. For the purpose of this specification, a source will refer to a specific bed at a specific quarry location. Gradation and evaluation testing will be at the expense of the quarry. If the quarry proposes an unapproved source, then the quarry will be responsible for the cost of gradation and evaluation testing. Evaluation testing of unlisted stone sources proposed by the quarry must indicate quality is equivalent or better than the approved sources for approval. 1.1 REFERENCES The publications listed below form a part of this specification to the extent referenced.

Stone protection is placed around structures in slack water or within a dewatered site. Stone protection may also be used to protect channel banks or shoreline when it is placed in the dry or in slack water. 1.2.2 Riprap Riprap is defined as a material having a gradation band similar to those specified in EM 1110-2-1601, Chapter 3, uniform graded material. Riprap is normally produced by mechanical methods, with a jaw crusher and grizzly after the stone has been mined by blasting in a quarry. The terms riprap and stone are used interchangeably in 35 31 19. 1.3 SUBMITTALS Government approval is required for submittals with a "G" designation; submittals not having a "G" designation are for information only. When used, a designation following the "G" designation identifies the office that will review the submittal for the Government. Submittals with the "DO" designation require review and approval by the District Office. Submit the following to the Missouri River Project Office, 790 E HWY 224, Napoleon, MO 64074.

Stone shall be of a suitable quality to ensure permanence in the structure and in the climate in which it is to be used. It shall be free from cracks, blast fractures, bedding, seams and other defects that would tend to increase its deterioration from natural causes. Inspections for cracks, fractures, seams and defects shall be made by visual examination. If, by visual examination, it is determined that 10 percent or more of the stone produced contains hairline cracks, then all stone produced by the means and measures which caused the fractures shall be rejected. A hairline crack that is defined as being detrimental shall have a minimum width of 4 mil and shall be continuous for one-third the dimension of at least two sides of the stone. The stone shall be clean and adequately free from all foreign matter. Any foreign material adhering to or combined with the stone as a result of stockpiling shall be removed prior to delivery. If an unapproved source is to be used, show that an adequate quantity of material is available and provide quality test data. 1.4.1.2 Sources Stone shall be furnished from one or a combination of approved sources. -- 3 of 13 -- Page 4 The quarry will pay all costs for gradation and evaluation tests from the approved source to assure the acceptability of the stone. The quarry will be responsible for sending suitable stone samples to a lab for evaluation testing of stone from sources with an adequate supply of material and submitting test results to the Missouri River Project Office. a. Selection of Source. Designate in writing only one source or one combination of sources from which the quarry proposes to furnish stone. If the quarry proposes to furnish stone from a unapproved source they shall notify the Missouri River Project Office at least 60 workdays before the stone leaves the quarry. It is the quarry's responsibility to determine that the stone source or combination…
