SUBMITTALS Seed Certification - Certification shall be submitted from the supplier for each type of seed specified. Certification shall accompany the delivery of the seed and shall indicate that the seed is in accordance with the requirements of the Texas Seed Law. Fertilizer Certification - Certification shall be submitted from the fertilizer manufacturer as to the chemical analysis of the fertilizer, a listing of the elements contained therein and their percentages. Certification shall also indicate that the fertilizer is in accordance with the requirements of the Texas Fertilizer Law. DELIVERY, STORAGE, AND HANDLINGSeed Delivery - Each variety of seed shall be delivered in separate bags or containers, labeled to indicate pure live seed, name and type of seed. Fertilizer Delivery - Fertilizer shall be delivered in the manufacturer's unopened containers, labeled to indicate the manufacturer's name and product identification. Containers shall be stored protected from ground contact and from the elements. GUARANTEE A written guarantee shall be provided guaranteeing to maintain the treated areas in a healthy, vigorous, undamaged condition for a period of 60 days beginning on the date of written acceptance of the work. Contractor shall guarantee a full stand of grass, 95% cover with no bare areas in excess of six inches diameter. Guarantee shall provide for timely filling, leveling and repairing eroded areas, reseeding areas exhibiting lack of healthy growth, and mowing as necessary to maintain a neat appearance. PRODUCTS MATERIALS Turfgrass Seed shall be appropriate to season. Harvested within 1 year prior to planting, free of Johnsongrass, field bind weed, dodder seed, and free of other weed seed to the limits allowable under the Federal Seed Act and applicable seed laws. Extra fancy grade, treated with fungicide, and shall have a germination and purity that will produce, after allowance for Federal Seed Act tolerances, a pure live seed content of not less than 85 percent, using the formula: %Purity x %Germanation = %Pure Live Seed. Labeled in accordance with U.S. Department of Agriculture rules and regulations. Amounts ItemRate Per 1000 Sq. Ft.SeedAs per season, see belowFertilizer7 lbs.WaterAs neededReal Virgin WoodMinimum 50 lbs. to achieveFiber MulchCovering of seeded area Spring/Summer Planting (April 15 to Sept. 15) Hulled Bermuda - 2 lbs./1000 Sq. Ft. Fall/Winter Planting (September 15 to April 15) Winter Rye - 10 lbs./1000 Sq. Ft. If Rye grass is installed, the Contractor shall reseed with Bermuda in the spring (May 1) after removing remaining Rye grass. TOPSOIL Topsoil shall be friable clay loam surface soil reasonably free of clay lumps, stones, weeds, roots and other objectionable material, a product of on site operations. FIRE ANT INSECTICIDE Spot treat fire ant insecticide in the entire area of seeding as Per Section 32 90 00 - Planting. FERTILIZER FOR FERTILIZING (Tank Mix) shall be Magestic Gro (18-5-9) as per section 32 90 00 Planting, grade, pelleted, uniform in composition, free flowing, and suitable for application with approved equipment. delivered to the site in bags or other convenient containers, each fully labeled, conforming to the applicable State fertilizer laws, and bearing the name or trademark and warranty of the producer. WOOD CELLULOSE FIBER MULCH Wood cellulose fiber mulch, for use with the hydraulic application of grass seed and fertilizer, shall consist of specially prepared wood cellulose fiber. It shall be processed in such a manner that it will not contain germination or growth inhibiting factors. It shall be an appropriate color to allow visual metering of its application. The wood cellulose fibers shall have the property of becoming evenly dispersed and suspended when agitated in water. When sprayed uniformly on the surface of the soil, the fibers shall form a blotter-like groundcover that readily absorbs water and allows infiltration to the underlying soil. Weight specifications from suppliers for all applications shall refer only to air-dry weight of the fiber, a standard equivalent to 19 percent moisture. The mulch material shall be supplied in packages having a gross weight not in excess of 100 pounds and be marked by the manufacturer to show the dry weight content. SLURRY MIX COMPONENTS PER ACRE Wood Cellulose Fiber Mulch - 2,000 pounds Grass Seed - As Specified Fertilizer (18-5-9) - As Specified EXECUTION INSPECTIONS Surfaces indicated to be seeded shall be inspected to verify that all preparatory work in the area has been completed. Seeding shall not start until all preparatory work has been completed. Requests for inspections shall be made at least two days prior to anticipate date of inspection. PREPARATION All areas to receive seed shall be stripped and/or treated with a contact herbicide prior to seeding as necessary to remove weeds, unless otherwise noted on drawings. Areas to receive seeding shall be loosened by manual or mechanical means to a depth of 1 1/2 inches, leveled and fine graded by hand raking. All stones (1" in diameter and larger in the top 2" of soil), tree stumps, brush, roots, vegetation, rubbish, and other foreign matter shall be removed from the site. No foreign matter may be buried on the site. All tree stumps must be removed to a depth of two (2) feet below finish subgrade. Weather Limitations Proceed with planting only when existing and forecasted weather conditions permit. APPLICATION Special Mulching Equipment and Procedures: Hydraulic equipment used for the application of fertilizer, seed, and slurry of prepared wood fiber mulch shall have a built-in agitation system with an operating capacity sufficient to agitate, suspend, and homogeneously mix a slurry containing up to forty (40) pounds of fiber plus a combined total of seventy (70) pounds of fertilizer solids for each one hundred (100) gallons of water. The slurry distribution lines shall be large enough to prevent stoppage. The discharge line shall be equipped with a set of hydraulic spray nozzles that provide even distribution of the slurry on the slopes to be seeded. The slurry tank shall have a minimum capacity of eight hundred (800) gallons and shall be mounted on a traveling unit which may be either self-propelled or drawn with a separate unit which will place the slurry tank and spray nozzles within sufficient proximity to the areas to be seeded so as to provide uniform distribution without waste. The Owner's Representative may authorize equipment with smaller tank capacity provided that the equipment has the necessary agitation system and sufficient pump capacity to spray the slurry in a uniform coat. Mixing: Care shall be taken that the slurry preparation takes place on the site of the work. Spraying shall commence immediately when the tank is full. Operators of hydromulching equipment shall be thoroughly experienced in this type of application. Apply specified slurry mix in a motion to form a uniform mat at specified rate. The operator shall spray the area with a uniform, visible coat by using the green color of the wood pulp as a guide. Keep hydromulch within areas designated and keep from contact with other plant material. Slurry mixture, which has not been applied within four (4) hours of mixing, shall not be used and shall be removed from the site. After installation, the Contractor shall not operate any equipment over the covered area. Immediately after application, thoroughly wash off any plant material, planting areas, or paved areas not intended to receive slurry mix. Keep all paved and planting areas clean during maintenance operations. Seeded Areas: If, in the opinion of the Landscape Architect, unplanted skips and areas are noted after hydromulching, the Contractor shall be required to seed the planted areas with the grasses that were to have been planted at no additional cost to the Owner. MAINTENANCE OF HYDROSEEDED AREAS After installation, hydroseeded areas shall be watered in an amount and as often as necessary to keep seed beds moistened to their full depth for a period of two weeks. After initial two weeks of watering, seeded areas shall be watered and maintained to insure a healthy, vigorous growth throughout the installation period and the landscape maintenance period. CLEANUP AND PROTECTION Promptly remove soil and debris created by lawn work from paved areas. MAINTENANCE Seeded areas shall be maintained in good condition throughout the duration of the project and the maintenance period in accordance with the maintenance described in Section 32 91 20.
