214.01 Description . This work consists of furnishing the specified seeds and inoculants
for legume seed, treating the legume seeds, and planting the seeds in a prepared and approved seedbed; covering the seeds and compacting the seedbed; and providing plant establishment on all areas seeded. All the work shall be in accordan ce with the plans and these specifications.
214.02 Materials . Seeds shall meet the requirement s of Subsection 715.03, subject to
the provisions of this subsection. The Contractor shall acquire seed from supplier registered with the MDAC. Except for the germination test as refere nced in Subsection 715.03, bags of seeds properly labeled or tagged according to law and indicati ng characteristics meeting or exceeding the requirements of these specifi cations will be acceptable for planting. The Contractor shall provide adequate dry and otherwise protected and approved storage facilities for seeds, and shall furnish access to the storage for sampling and for the Engineer to inventory stored seed and inspect the suitability of the storage facilities. Seeds that have been sampled and tested by the MDAC shall be acceptable for planting provided (1) that prior to planting, the Contractor furnishes the Engineer two copies of test reports from the MDAC indicating that the seeds meet the germination requirements,
2.not more than nine months have elapsed, exclusive of the calendar month in which the test was completed, between the germination test data and the time of planting, and (3) the seeds were properly stored and handled. Seeds that have not been sampled and tested by the MDAC and test reports furnished prior to planting shall be sampled and tested for germination requirements by the Department. The Contractor may use pre-tested, or post-tested seeds under the conditions stated herein. For seeds to be pre-tested, approximately 35 days from the date of sampling will Section 214 Section 214 be required to obtain the test results. When pre-tested seeds are planted, a minus tolerance of five percent of the specified germination percentage will be allowed without adjustment. Seeds failing to comply by more than five percent may be planted, provided the rate of seeding is increased by 100 percent of the deficiency with the same or approved seeds, without additional compensation. The Engineer may permit the Contractor to plant post-tested seeds, provided the seeds are properly tagged and have indicated characte ristics meeting the requirements of these specifications without applying tolerances. If the seeds are planted, the Contractor shall assume full responsibility for the specified percent germination of the seeds upon subsequent tests. Acceptance or re-sowing will be based on the results of the subsequent tests. A minus tolerance of five percent of the specified germination percentage will be allowed without adjustment. If the tests indicat e a deficiency in excess of five percent;
1.the deficiency shall be corrected by immediately re-sowing an amount of seeds equal to 200 percent of the deficiency with the same or approved seeds without additional compensation, or (2) should it be determined, by inspection, that a sufficient number of seeds have germinated to produce satisfactory growth and coverage, the Engineer will deduct from measured quantities an amount of seeds equal to l00 percent of the deficiency. Otherwise, the area seeded w ill not be considered in reasonably close conformity with the requirem ents of these specifications.
214.03 Construction Requirements .
214.03.1 General . Prior to planting the seeds, topsoil when specified, ground
preparation, and fertilizing shall have been satisfactorily performed and the area approved by the Engineer. Seeding may be required for temporary protection or for establishment of permanent ground cover. The plans will indicate temporary seeding. The rates of application, kinds, and the planting dates of seeds shall be as set out in the vegetation schedule on the plans. The Engineer will determine the actual quantity of seeds to be applied on individual areas of not more than three acres. Legume seeds shall be treat ed in accordance with Subsec tion 715.03.4 immediately before sowing. Seeds shall be uniformly sown over the entire area with approved mechanical seeders. Seeds of different sizes may necessitate separate sowing. Should legume seeds become dry, they shall be re-inoculated. Seeding shall not be done during windy weather or when the ground is frozen, extremely wet, or in a condition that will not allow the soil to be properly tilled. All seeds shall be covered lightly with soil by raking, rolling, or other approved methods, and the area compacted with a cultipacker. When specified, mulching shall be performe d in accordance with th e requirements of Section 215 as soon as practicab le but no later than 24 hours after seeding unless weather conditions are such that mulch cannot be placed. Section 214 Section 214
214.03.2 Plant Establishment. The Contractor shall provide plant establishment on all
areas seeded until release of maintenance. Plant establishment shall be provided for a minimum period of 45 calendar days after completion of seeding. In the event satisfactory growth and coverage has not been attained by the end of the 45-day period, plant establishment shall be continued until the specified growth and coverage is provided for at least one kind of plant as referenced in Section 210. The Contractor shall perform plant establishment on all areas of temporary seeding until the Engineer determines that the temporary seeding has served its purpose. Plant establishment shall consist of preservi ng, protecting, watering, reseeding, mowing, and other work necessary to keep the seeded areas in satisfactory condition. Unless otherwise permitted, areas requiring reseeding shall be prepared and seeded and all other work performed in accordance with th e requirements of the contract as if the reseeding was the initial seeding. The types and application rates of fertilizer will be determined by soil tests or otherwise established. 214.03.3--Growth and Coverage . It shall be the Contractor's responsibility to provide satisfactory growth and coverage of grasses, legumes, or combination produced from the specified seeding. Growth and coverage on seeded areas will be considered to be in reasonably close conformity with the intent of the contract when the type of vegetation specified, exclusive of that from seeds not expected to have germinated and shows growth at that time, has reached a point of maturity wh ere stems or runners overlap adjacent similar growth in each direction over the entire area.
214.04 Method of Measurement . Seeding will be measured by the acre, or by the
pound, as indicated in the contract. Except as provided under Subsection 107.17, no measurement for payment will be made for any materials or work required under Subsections 214.03.2 and 214.03.3. Watering for seeding will not be measured for separate payment.
214.05 Basis of Payment . Seeding, measured as prescribed above, will be paid for at
the contract unit price per acre or per pou nd, as indicated, which price shall be full compensation for co mpleting the work. Payment will be made under: 214-A: Seeding, Kind - per acre or pound 214-B: Seeding, Seed Mixture, Designation - per acre SECTION 215 - MULCHING
