1.3 DEFINITIONS

1.3.1 Stone Protection

Stone slope protection is defined as a layer of riprap or river cobbles.

1.3.2 Groins

Groins are defined as an elongated rock structure having one end attached to the bank and the other end protruding into the river flow. Groins act to reduce velocities along the bank and create a backwater upstream of the structure.

1.3.3 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 or as noted in this specification. Riprap is normally produced by mechanical methods, with a jaw crusher and grizzly after the stone has been mined by blasting in a quarry. Riprap gradations have a maximum top size of 3.5 tons.

1.3.4 Grade Control Sill

A grade control sill is defined as a rock grade control structure to include the horizontal crest, the upstream and downstream slopes, and the heal and toe keys, and channel. Rock for the sill will originate from the onsite riprap armoring the SR 24 Cross Dike or other onsite sources with equivalent characteristics.

1.3.5 River Cobble

River Cobble consists on onsite granualar alluvium that includes 50% or more material in excess of 4-inches in diameter and no more than 15% of material finer than 1 to 2 inches. Material originates from channel excvation work and is not mechanically screened but should be mixed in stockpiles to produce an even gradation when placed. Material may include fines and boulders but is predominately gravel and cobble sized materials, similar to what would be found on the surface of the Yakima River bed or gravel bar. River cobble is used as armor stone in areas that have moderate to low velocities during floods. After ground disturbing activities commence submit locations that are suitable for River Cobble borrow.

1.3.6 Anchor Boulders

Anchor Boulders are large stone particles used for ballasting or holding down LWD and are of natural or quarry origin. Rounded to sub-rounded boulders are preferred over quarried boulders. See 35 44 00 for placement requirements.

1.5 QUALITY ASSURANCE

1.5.1 Stone

1.5.1.1 General

All stone shall be durable material as approved by the Contracting Officer and as required by EM 1110-2-2302 . The Contractor shall show that an adequate quantity of material is available and provide quality test data in accordance with this specification, EM 1110-2-2302 , and all other relevant standards and requirements. All stone shall be of a suitable

SECTION 35 31 19 Page 5 quality to ensure permanence in the structure and in the climate in which it is to be used. The stone shall be hard, durable, angular, and free from cracks, blast fractures, bedding, seams, vugs, veins, and other defects or discontinuities 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, or other defects, 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 (0.004 inch)and shall be continuous for one-third the dimension of at least two sides of the stone. The stone shall be clean and free from all foreign matter for inspection. Any foreign material adhering to or combined with the stone as a result of stockpiling shall be removed prior to placement. The selected stone shall match as close as possible the color of the existing riprap on the upstream face of the embankment that shall be left in place adjacent to the work area when tested dry and wet.

1.5.1.2 Sources

The Contractor shall furnish the stone from the source to the Contracting Officer, subject to the conditions herein stated. The Government shall conduct a quarry investigation and evaluate the quality test data provided by the Contractor to determine whether acceptable stone can be produced from the proposed source after the Contractor has completed the Quarry Inspection and report as required in Paragraph Evaluation Testing of Stone

- Investigation and Testing. The Contractor shall be responsible for arranging the quarry inspection site visit and shall provide the Contracting Officer a minimum of 10 days notice of the time and location of the visit.

Satisfactory service records of the stone at other work shall be provided to the Contracting Officer. In order for stone to be acceptable on the basis of service records, stone of a similar size, and from similar formation or ledge, must have been placed in a similar thickness and exposed to weathering under similar conditions as are anticipated for this contract, and must have satisfactorily withstood such weathering for a minimum of 20 years. In addition to an acceptable 20 year service record, the Contracting Officer has the option to elect to have representative samples taken and tested.

a. Selection of Source. The Contractor shall designate in writing only one source for stone. The Contractor shall notify the Contracting Officer at least 60 workdays before the stone leaves the quarry. It is the Contractor's responsibility to determine that the stone source selected is capable of providing the quality, quantities and gradation needed and at the rate needed to maintain the scheduled progress of the work. Samples for acceptance testing shall be provided in accordance with this specification. If a source for stone so designated by the Contractor is not accepted for use by the Contracting Officer, the Contractor shall be required to find another source.

b. Acceptance of Materials. Acceptance of a source of stone is not to be construed as acceptance of all material from that source. The right is reserved to reject materials from certain localized areas, zones, strata, ledges, or channels, when such materials are unsuitable for stone as determined by the Contracting Officer. The Contracting Officer also reserves the right to reject individual units of produced

SECTION 35 31 19 Page 6 specified materials in stockpiles at the quarry, all transfer points, and at the project construction site, when such materials are determined to be unsuitable.

During the course of the work, the stone may be tested by the Government, if the Contracting Officer determines that testing is necessary. If such tests are determined necessary, the testing will be done in commercial laboratory selected by the Government.

Materials produced from a source shall meet all the requirements herein. The cost of testing will be at the Contractor's expense.

During the contract period, both prior to and after materials are delivered to the job site, visual inspections and measurements of the stone materials may be performed by the Contracting Officer. If the Contracting Officer, during the inspections, finds that the stone quality, gradation, or weights of stone being furnished are not as specified or are questionable, re-sampling and re-testing by the Contractor shall be required. Sampling of the delivered stone for testing and the manner in which the testing is to be performed shall be as directed by the Contracting Officer. This additional sampling and testing shall be performed at the Contractor's expense. When test results indicate that materials meet specified requirements, an equitable adjustment in the contract price will be made for the sampling and testing. Rejected material shall be removed from the Project site at no cost to the Government.

1.5.1.3 Evaluation Testing of Stone Source

The tests to which the stone may be subjected will include petrographic analysis, specific gravity, unit weight, absorption, wetting and drying, freezing and thawing, and such other tests as may be considered necessary to demonstrate that the stone is of a satisfactory quality. All tests shall be performed as described below or in PART 2. If the Contractor proposes a laboratory which is not validated to perform the tests specified (as described in paragraph Laboratory Certificates, all costs and time associated with validating the laboratory shall be borne by the Contractor.

a. Unit Weight, Bulk Specific Gravity, saturated surface dry (SSD) and Absorption.

Stone shall weigh more than 162 pounds per cubic foot shall have a bulk specific gravity, saturated surface dry, (SSD), greater than

2.6. The stone shall have an absorption less than 2 percent. The method of test for unit weight bulk specific gravity (SSD) and absorption will be ASTM C 127 , except the unit weight will be calculated using bulk specific gravity, saturated surface dry.

b. Samples. Samples of stone from a source shall be taken by a representative of the quarry to the approved laboratory under the supervision of the Contracting Officer for testing and acceptance prior to delivery of any stone from this source to the site of the work. The Contractor shall be responsible for arranging sampling and transport and shall notify the Contracting Officer a minimum of 10 days before the activity.

Samples shall consist of at least three pieces of stone, roughly cubical in shape and weighing not less than 150 pounds each from each unit that will be used in the production of the required stone. If the source is an undeveloped quarry, or if the operation has been

SECTION 35 31 19 Page 7 dormant for more than one year, such that fresh samples are not available, the Contractor shall expose fresh rock for 20 feet horizontally and for the full height of the face proposed for production, prior to the field evaluation. The Contracting Officer may also require documentation of subsurface exploration of an undeveloped quarry in order to determine whether or not sufficient reserves are available.

1.5.1.4 Random Sampling

The stone produced by each source may be sampled by the Government for Quality Assurance testing on the basis of a minimum once each year or once during the production of each 25,000 tons of stone produced each year for the Government. The samples will be evaluated based upon petrographic analysis, specific gravity, unit weight, bulk specific gravity (SSD), and absorption. All random sampling and testing costs shall be borne by the Contractor. Random sampling shall comply with Paragraph Evaluation Testing of Stone.

1.5.1.5 Drop Test

A drop test provides an immediate evaluation of the durability of very large stone during handling of the stone including placement into a structure. For comparability, the test stones shall be dropped from a bucket or by other means from a height of not less than half the average diameter of the stone onto a clean, rigid, nondeflecting surface or second stone of comparable size set on a nonyieldinig surface. Dumping from a truck is not acceptable.

The stone shall be examined carefully before as well as after the completion of the test. Failure criteria is the development of new cracks, opening of old cracks, and the loss of piece from the surface of the stone. Each stone shall be dropped a total of five times for evaluation purposes with examination after each drop. The Contractor shall provide all necessary equipment and operating personnel to perform the testing.

The drop test shall be performed in the presence of the Contracting Officer or representative and USACE Seattle District Geotechnical and Geological personnel at the stone production site. The Contractor shall arrange all testing and shall provide the Contracting Officer a minimum of 10 days notice before the tests are to be performed.

The testing shall require the selection of five suitable stones from each weight size listed for aggregate filter (if specified) and riprap by the Contractor and the USACE. Selected stones shall be approved by the USACE before testing. All stones shall be clean of dust, dirt, debris, or other material that may hinder inspection. Material shall be representative of the stone that shall be used for the work.

The Contractor shall record the results of each test and photograph the stone before the test and the resulting impact of each drop test on each stone. The Contractor shall provide this Drop test record to the Contracting Officer within 5 days of the completion of the tests.

Random drop tests of stone selected by the USACE shall be performed during construction. If the stone fails, the placed material shall be closely inspected. All material displaying hairline cracks shall be removed at no cost to the Government. An additional drop testing program shall be

SECTION 35 31 19 Page 8 conducted at the stone production site and the quarry stone source shall be inspected for quality. All costs of this additional testing shall be borne by the Contractor at no additional expense to the Government. All material that is rejected and requires removal at the work site shall be taken off the Project site and disposed of at no cost to the Government.

The Contractor shall provide suitable replacement stone to replace the rejected material at no cost to the Government.

1.6 CONSTRUCTION TOLERANCES

The finished surface and stone layer thickness shall not deviate from the lines and grades shown by more than the tolerances listed below.

Tolerances are measured perpendicular to the indicated neatlines. Extreme limits of the tolerances given shall not be continuous in any direction for more than five times the nominal stone dimension nor for an area greater than 100 square feet of the structure surface.

NEATLINE TOLERANCES

MATERIAL ABOVE NEATLINE (inches) BELOW NEATLINE (inches)

Riprap 2 2

The intention is that the work shall be built generally to the required elevations, slope and grade, and that the outer surfaces shall be even and present a neat appearance. Placed material not meeting these limits shall be removed or reworked as directed by the Contracting Officer. Payment shall not be made for excess material, which the Contracting Officer permits to remain in place.

PART 2 PRODUCTS

Products shall be as specified below. Materials shall not be amended at the quarry or other location with sand, silt, cuttings, or other quarry cleaning or material products to meet a desired weight for hauling. All materials shall be washed to removed fine particles and allow inspection. Loads arriving at the work site that have been amended with excess fines to meet weight or have not been washed shall be reject and returned to the source at no expense to the Government. All products which require Government approval, must be submitted and approved prior to staging or delivery of materials.
