801.04 General
Perform seeding work as specified in 209. At the start of permanent seeding operations, prepare, shape, and dress the area to be seeded as specified in 203.08 and 801.05. Unless otherwise directed by the Engineer, do not sow the seed until after placing the topsoil as specified in 203.06. Use topsoil with all permanent seeding activities except where its use would be detrimental to effective erosion and siltation control, as determined by the Engineer . The Contractor may perform Temporary Seeding (with Mulch) or Temporary Seeding (without Mulch) without full preparation of the seedbed as specified in 801.05 , where approved by the Engineer, and application of permanent erosion and siltation control measures is not practicable. Perform all seeding and related operations as continuous operations. A unit in relation to seeding ar ea is 1,000 square feet. For purposes of measuring water, a unit is 1 M.G., which equals 1,000 gallons.
801.05 Preparing the Seedbed
When the soil is in a tillable and workable condition, prepare the seedbed in the following manner and se quence:
1.Scarify, disc, harrow, rake, or otherwise work each area to be seeded until it has been loosened and pulverized to a depth as directed by the Engineer.
2.Incorporate fertilizer, at the rate of not less than 20 pounds of Grade 10-10-10, or equiv alent, per unit (1,000 square feet), and agricultural limestone, at the rate of not less than 100 pounds per unit, uniformly into the soil for a depth of approximately 1/2 inch.
3.If the soil pH is below 5.5, in addition to the required agricultural lime, apply liquid lime selected from the Department’s QPL at a rate of 7.5 gallons per acre (22 ounces per 1,000 square feet). 801.06 871 Incorporating fertilizer into the soil as specified above is not necessary when mixed with seed in water and applied with power s prayer equipment.
801.06 Seeding
The specific seed group will be shown on the Plans or as directed by the Engineer from those specified in 918.01. Sow the seed immediately after preparing the seedbed as specified in 801.05. Sow the seed uniformly using a rotary seeder, hydraulic equipment, or other satisfactory means, at the rate specified in Table 801.06 -1, unless otherwi se specified or directed. Table 801.06 -1: Seed Application Rates Seed Group Application Rate, Pounds per Unit (1,000 square feet) A, B, and C 2.5 B1 0.6 All other groups specified in 918.01 1.5 Before sowing, inoculate Group C seed and seeds of legumes, when sown alone, in accordance with the recommendations of the inoculant manufacturer and as directed by the Engineer. Do not perform any seeding during windy weather or when the ground surface is frozen, wet, o r otherwise non -tillable. Do not perform seeding during December and January unless otherwise allowed.
801.07 Mulching
When seeding with mulch is specified, use hay, straw, or other approved mulch materials. When using hay or straw as th e mulching material, spread it evenly over the seeded area, immediately following the seeding operations, at an approximate rate of 100 pounds per unit for straw and 150 pounds per unit for hay. The Engineer may vary this rate, depending on the texture an d condition of the mulch material and the characteristics of the area seeded. 801.08 872 To hold hay or straw mulch in place, apply an approved tackifier, listed on the QPL, as recommended by the manufacturer. When using wood fiber mulching material , apply it at a rate of 28 to 35 pounds per unit, using hydraulic mulching equipment . Spray the material uniformly on the surface of the prepared seedbed. Adjust the a pplication rate as directed by the Engineer.
801.08 Care During Construction
Maintain all seeded areas to the Engineer’s satisfaction until acceptance of the Work. Repair, as directed by the Engineer, all areas previously seeded and mulched in accordance with this Section but that incurred da mage or failed to successfully establish an acceptable stand of grasses or legumes. Furnish all material and labor required to repair seeded areas damaged due to Contractor negligence at no cost to the Department. The Department will measure and pay for repairs made to seeded areas, except temporary seeding, required through no fault of the Contractor, in accordance with 801.09 and 801.10. If the Engineer directs the Contractor to place additional fer tilizer on the area to be reseeded, apply additional liquid lime at a rate of 5 gallons per acre (15 ounces per 1,000 square feet) if the pH of the soil is below 5.5. After an acceptable stand of grass has been attained, top -dress seeded areas with not less than 10 pounds of fertilizer of Grade 10 -10-10, or equivalent, per unit at approximately 6 -month intervals, unless otherwise specified or directed. COMPENSATION
801.09 Method of Measurement
A.Seeding The Department will measure the seeded area for pay ment by the number of units seeded in accordance with these Specifications and accepted by the Engineer. Each unit shall consist of 1,000 square feet measured along the surface. 801.09 873 B. Mulch The Department will measure mulch for payment complete and in place, including tackifiers used to hold the mulch in place.
C.Water The Department will measure water necessary for seedbed preparation and maintenance by the M.G. (1,000 gallons) using calibrated tanks or distributors, or accurate water meters. The Department wil l not measure water used in applying seed, fertilizer, and mulch binder.
D.Repairs of Seeded Areas The Department will measure supplemental items used to repair seeded areas on which a satisfactory stand of grasses or legumes has not been obtained due to ca uses not attributable to Contractor negligence as provided below. These items will only be used when the reseeding is confined to small areas that would not restrict the Contractor’s operation. If the areas to be reseeded are of substantial size, thereby accommodating the Contractor’s normal operation, the Contractor shall perform the work in accordance with these Specifications, and the Department will pay for such work under the applicable original seeding item.
1.The Department will not pay for seedbe d repair directly but will consider the cost thereof as included in the unit price bid for Seed (Supplemental Application). If additional materials are required to repair the seedbed, the Department will make payment under the appropriate item or items in 203.
2.The quantity of seed measured for payment to repair seeded areas will be the actual number of pounds of seed used, as determined by bag count of standard weight bags or by weighing the seed on approved scales.
3.The quantity of fertilizer measured for payment will be the actual number of tons of dry fertilizer used as determined by bag count of standard weight bags or by weighing the fertilizer on approved scales. If liquid fertilizer is used, the weight will be converted to its equivalent dry weight in tons. 801.10 874 E. Fertilizer The Department will measure f ertilizer applied, as specified or directed, to areas with an acceptable stand of grass as specified in 801.09.D.3 .
F.Lime The Department will measure lime for payment complete and in place by the ton. The Department will make no direct measurement or payment for agricultural limestone or liquid lime used in repairing seeding areas, but will consider the cost to be included in the unit price bid for Fertilizer.
