3. MATERIALS:

3.1 Seed. Shall be state-certified seed of the latest season's crop and shall be delivered in original sealed packages bearing the producer's guaranteed analysis for percentages of mixtures, purity, germination, weed-seed content, and inert material. Seed shall be labeled in conformance with U.S. Department of Agriculture rules and regulations under the Federal Seed Act and applicable state seed laws. Seed that has become wet, moldy, or otherwise damaged will not be acceptable.

3.2 Sod. Shall be predominately Centipede nursery grown or natural field sod.

3.3 Topsoil. Shall be the existing surface soil stripped and stockpiled on the site.

3.4 If additional topsoil is required, it shall be furnished by the Contractor from approved sources off the site and shall be a natural, friable soil representative of productive soils in the vicinity.

It shall be obtained from well-drained areas and shall be free of admixture of subsoil and foreign matter or objects larger than one inch in any dimension, toxic substances, and any material or substance that may be harmful to plant growth. The pH range shall be 5.3 to 6.0.

Topsoil that does not meet this pH range shall be amended by the addition of lime.

3.5 Fertilizer: Shall be commercial grade 8-8-8, free flowing, uniform in composition and shall conform to applicable state and federal regulations.

3.6 Mulch:

1. Straw shall be stalks from oats, wheat, rye, barley, or rice that are free from noxious weeds, mold, or other objectionable material. Straw shall be in an air-dry condition and suitable for placing with blower equipment.

2. Hay shall be of herbaceous mowings, free from noxious weeds, mold, or other objectionable material. Hay shall be in an air-dry condition and suitable for placing with blower equipment.

3. Wood cellulose fiber for use with hydraulic application of grass seed and fertilizer shall consist of specially prepared wood cellulose fiber, processed to contain no growth or germination-inhibiting factors and dyed an appropriate color to facilitate visual metering of the application of materials. On an air-dry weight basis, the wood cellulose fiber shall contain a maximum of 12 percent moisture, plus or minus three percent at the time of manufacture. The pH range shall be from 3.5 to

2. When hydraulically sprayed on the ground the material will form a blotterlike cover impregnated uniformly with grass seed.

3. The cover will allow the absorption of moisture and allow rainfall or applied water to percolate to the underlaying soil.

4. DELIVERY AND STORAGE.

4.1 Delivery. The Contractor shall notify the Engineer of the delivery schedule in advance so material may be inspected upon arrival at the job site. Unacceptable material shall be removed from the job site immediately.

4.2 Fertilizer shall be delivered to the site in the original, unopened containers bearing the manufacturer's guaranteed chemical analysis, name, trade name, trademark, and conformance to state and federal laws.

4.3 Storage. Seed, and fertilizer shall be kept in dry storage away from contaminants.

5. PLACING TOPSOIL.

5.1 Topsoil shall be distributed uniformly and spread evenly to a minimum thickness of 2 inches.

Topsoil shall be spread so that planting can proceed with little additional soil preparation or additional soil preparation or additional tillage. Surface irregularities resulting from topsoiling or other operations shall be leveled to prevent depressions. Grade shall be adjusted to assure that planted grade will be 1 inch below adjoining grade of any surfaced area. Topsoil shall not be placed when the subgrade is frozen, excessively wet, extremely dry, excessively compacted, or in a condition detrimental to the proposed planting or grading. Soil compacted construction equipment or soil on compacted cut slopes of grades shall be pulverized to a minimum depth of 2 inches by disking or plowing before applying topsoil.

6. PREPARATION OF SEED BED.

6.1 The seed bed shall be prepared by breaking, disking, harrowing, blading, dragging or other approved methods. The soil shall be thoroughly pulverized to a minimum depth of approximately 3 inches and leveled as directed. The surface soil shall be firmed by lightly

FA4608-16-R-0011

rolling the area with a cultipacker. If natural firming by rain has occurred, the rolling may be eliminated. All sticks, debris, and other foreign matter must be removed and the soil left in a suitable horticultural condition to receive the seed. Fertilizer shall be spread over the areas and incorporated into the soil during the preparation of the seed bed. Should erosion control measures become necessary, the Contractor shall furnish such protection as is required at his own expense.

7. SEEDING.

7.1 Centipede grass seed shall be broadcast at the rate of 30 pounds per acre either by hand crank seeders or with the approved hydraulic equipment in combination with wood cellulose fiber mulch and fertilizer as specified hereinbefore, or with other approved sowing equipment.

Seed shall be distributed uniformly over designated areas. Half of seed shall be sown with sower moving in one direction, and the remainder with sower moving at right angles to first sowing. Seed shall be covered to an average depth of 1/4 inches by brush harrow, spike-tooth harrow, chain harrow, cultipacker, hand rake with wood tines, or other approved device. Seed shall not be broadcast during windy weather.

8.1 Fertilizer shall be applied at the rate of 1000 pounds per acre based upon the application of type 8-8-8 fertilizer. Fertilizer used shall be in accordance with requirements of the Louisiana Department of Agriculture, Fertilizer Division.

9. MULCHING.

9.1 Mulch shall be spread uniformly in a continuous blanket, using 1-1/2 tons per acre. Mulch shall be spread by hand or by a blower-type mulch spreader or other suitable equipment.

Mulching shall be started at the windward side of relatively flat areas, or at the upper part of a steep slope, and continued uniformly until the area is covered. The mulch shall be anchored to the soil by a V-type-wheel, or other suitable equipment, or by strings and stakes. Asphalt adhesive may be used with approval of the Engineer. Wood cellulose fiber mulch for use with the hydraulic application of seed and fertilizer shall be applied at the rate of 1400 pounds per acre.

10. SODDING.

10.1 Sodding shall be placed where indicated on the drawings. After the sodding operation has been completed, the edges of the sodded area shall blend smoothly into the surrounding area.

11. ESTABLISHMENT OF GRASS GROWTH.

11.1 The Contractor shall be responsible for the establishment of a satisfactory grass growth on the seeded areas and shall protect and maintain such grass growth, including watering and mowing until final acceptance of all the work to be performed under this contract. All watering and any re-seeding necessary to establish a satisfactory grass growth over all areas shall be done by and at the expense of the Contractor. Final acceptance will not be made until a satisfactory grass growth has been established.

11.2 If weeds or other vegetation growth to a height that they threaten to smother the plant species, they shall be mowed, raked, and removed from the area. When the surface of any part of an area which has been planted is gullied or otherwise damaged, the affected portions shall be repaired to re-establish the condition and grade of the soil prior to the injury and then re-seeded by and at the expense of the Contractor.

FA4608-16-R-0011

12. WATERING.

12.1 After the seed has been planted, the area shall be watered immediately with approved watering tanks unless, in the opinion of the engineer, there is sufficient moisture to eliminate watering. After the first watering operation other waterings will follow as directed. These watering operations will continue as necessary until the project is finally accepted. The water for seeding purposes shall be obtained from an approved source.

13. COMPLETION.

13.1 If all other work is completed, with the exception of the establishment of a satisfactory grass growth, partial acceptance of the work will be made with final acceptance delayed until a satisfactory grass growth has been established. Liquidated damages will not be assessed against the Contractor during the interim period between the date of such partial acceptance and the date of final acceptance if such delay is the result of seasonal limitations.
