3.2.2 Seed Application Method

Seeding method must be drill seeding or hydroseeding unless otherwise specified.

3.2.2.1 Drill Seeding

Seeding must be drilled at a rate of 100200 pounds pure live seed per acre. Drill seed uniformly to average depth of 1/4 inch.

3.2.2 Hydroseeding

First, mix water and fiber. Wood cellulose fiber, paper fiber, or recycled paper must be applied as part of the hydroseeding operation. Fiber must be added at 1,000 pounds, dry weight, per acre. Then add and mix seed and fertilizer to produce a homogeneous slurry. Seed must be mixed to ensure broadcasting at the rate of 100200 pounds pure live seed per acre. When hydraulically sprayed on the ground, material must form a blotter like cover impregnated uniformly with grass seed. Spread with one application with no second application of mulch.

2.2.2 RIPRAP

The upper table is for “RIPRAP GRADATION FOR UPSTREAM SLOPE” and the lower table is for “RIPRAP GRADATION FOR OUTLET CHANNEL” Delete additional label at the lower table RIPRAP GRADATION FOR UPSTREAM SLOPE

3.8.3.2 Riprap

Gradation tests shall be performed in accordance with ASTM D5519, Test Method A. The Contractor shall perform gradation tests at the quarry. The sample shall be taken by the Contractor in the presence of the COR. The Contractor shall notify the COR not less than 3 days in advance of each test. In the event of the unavailability of the contracting office, the Contractor shall perform the tests and certify to the COR that the material shipped complies with the specifications. At least one gradation test shall be performed per 15,000 tons of riprap placed and shall be collected in a random manner which will provide a sample that accurately reflects the gradation arriving at the jobsite. The sample shall consist of not less than 25 tons of stone and shall be collected in a random manner which will provide a sample which accurately reflects the actual gradation arriving at the jobsite. The gradation tests shall be reported using the attached forms, GRADATION TEST DATA SHEET and ENG FORM 4055. The Contractor shall designate on the test form that portion, in tons, of the lot tested which is applicable to the contract. Any deviation from the reported tonnage shall be corrected and recorded on a revised GRADATION TEST DATA SHEET. Failure of the test on the initial sample and on an additional sample will be considered cause for rejection of the quarry and/or quarry process, and all riprap or bedding represented by the failed tests shall be set aside and not incorporated into the work. Any additional tests required because of the failure of an initial test sample will not be considered as one of the other required tests. If collected by the truckload, each truckload shall be representative of the gradation requirements. Certification and test results shall represent materials shipped from the quarry. Certification and test results must be received by the COR at the jobsite before the riprap is used in the work.

3.1 SHORING

Construct shoring in accordance with the safety requirements of EM 385-1-1. Submit drawings and calculations, certified by a registered professional engineer, describing the methods for shoring and sheeting of excavations at least 30 days prior to installation. Also include sequencing and methods of shoring installation and removal that will facilitate verification that the methods will not leave voids, seepage paths, or other deficiencies. The Contractor is responsible for design and maintenance of all shoring to be installed. Do not negatively impact existing and proposed work during installation. Unless otherwise authorized, remove all sheeting and bracing when backfill is completed. Do not negatively impact completed work during removal.

3.2 EARTHWORK

Bear the reinforced fill zone on undisturbed native soils, or acceptably placed and compacted fill. In the event that it is necessary to remove material or place fill below the excavation lines shown on the drawings, or not otherwise provided for in the contract, notify the Contracting Officer prior to work and an adjustment in the contract price will be considered in accordance with the contract. It is at the Contractor's expense if additional work not authorized by the Contracting Officer is performed.

Excavation

Excavate to contours, elevation, and dimensions indicated. Reuse excavated materials that meet the specified requirements for the material type required at the intended location. Keep excavations free from water. Excavate soil disturbed or weakened by Contractor's operations, soils softened or made unsuitable for subsequent construction due to exposure to weather.

Excavations below indicated depths will not be permitted except to remove unsatisfactory material. Remove as directed unsatisfactory material encountered below the grades shown.

Refill with satisfactory material and compact to 95 percent of ASTM D698 maximum density.

Replace satisfactory material removed below the depths indicated, without specific direction of the Contracting Officer, with satisfactory materials to the indicated excavation grade; except as specified for spread footings. Determination of elevations and measurements of approved overdepth excavation of unsatisfactory material below grades indicated will be done under the direction of the Contracting Officer. Perform excavation and fill in a manner and sequence that will provide proper drainage at all times. The Contractor is responsible for disposal of surplus material, waste material, and material that does not meet specifications, including any soil which is disturbed by the work operations or softened due to exposure to the elements and water.

Stockpiles

Stockpile material for backfilling in a neat and orderly manner at a sufficient distance from the banks of the excavation to avoid overloading and to prevent slides or caving. Keep stockpiles of all material to be incorporated into the work in a neat and well drained condition, giving due consideration to drainage at all times. Clear, grub, and seal the ground surface at stockpile locations. Stockpile topsoil separately from suitable backfill material. Protect stockpiles of aggregates and granular soils from contamination which can destroy the quality and fitness of the stockpiled material. If the Contractor fails to protect the stockpiles, and any material becomes frozen, saturated, intermixed with other materials, or otherwise out of specification or unsatisfactory for the use intended, remove such material and replace with new material from approved sources at no additional cost to the Government.

3.7.4 Testing Schedule

c. Sieve Analysis, (ASTM C136/C136M)

Drainage Aggregate, 1 test for each source.

3.11 SEEDING
