Section 215 Section 215 Whether by use of a mulch stabilizer or by application of bituminous material, anchoring of vegetative mulch will not be measured for separate payment. The cost of anchoring shall be absorbed in the prices bid for other items of work. Acceptable quantities of hydromulch will be measured by the ton. The weight for measurement of hydromulch will be the dry weight of the packaged fibers used in the mixture. No separate payment will be made for water, additives, tackifier, or other liquids used in the mixture.
215.05 Basis of Payment . Vegetative material for mulch will be paid for at the contract
unit price per ton and shall be full compensation for completing the work. Hydromulch, measured as prescribed above, will be paid for at the contract unit price per ton, which price shall be full compensation for all materials, equipment, labor, and incidentals necessary to complete the work. Payment will be made under: 215-A: Vegetative Materials for Mulch - per ton 215-B: Hydromulch - per ton SECTION 216 - SOLID SODDING
216.01 Description . This work consists of furnishing, transporting, and planting
approved grass sod in accordance with the plans and these specifi cations. This work shall also include plant establishment as sp ecified and required to assure satisfactory growth of the solid sod.
216.02 Materials . Unless otherwise specified, solid sod shall be common bermuda,
bahia, or other approved sod species and shall be live, fresh, growing grass, unless in the dormant season, with at least one and one-half inches of soil adhering firmly to the roots when placed. The sod shall be reasonably fr ee from obnoxious weeds or other grasses, and shall not contain any matter deleterious to its growth, or that might affect its subsistence or hardiness when transplanted. The sod shall be in blocks at least eight inches by eight inches and r easonably free from ragged edges. All sod shall be harvested from areas where the topsoil is fertile, and the areas shall have been grazed or mowed sufficiently to form a dense turf. The area from which the solid sod is to be harvested shall be closely mowed, and raked if deemed necessary to remove excessive top growth and debris. When a kind of solid sod is specified, the ma terial shall be nurser y grown, healthy, free from damage, and free from noxious weeds and grasses. The nursery grown sod shall be in blocks at least eight inches by eight inches by one inch and reasonably free of ragged edges. All solid sod materials shall be approved by the Engineer prior to transplanting.
216.03 Construction Requirements .
216.03.1 Procuring and Handling Sod . Approved sod cutters shall be used for cutting
the sod into strips or blocks. Care shall be exercised at all times to retain the native soil on the roots of the sod during the process of excavating, hauling, and planting. The sod shall be transplanted within 24 hour s after arriving on the project, unless it is stacked in a manner satisfactory to the Engin eer. All sod in stacks shall be kept moist and protected from exposure to the wind and sun and from freezing. In no event shall more than three days elap se between the cutting and planting of the sod without approval of the Engineer.
216.03.2 Grading of the A rea to Receive Solid Sodding . Prior to ground preparation
for solid sodding, all excavating, shaping, and dressing shall have been completed in such a manner that the foundation for the sod has th e proper cross section, line, and grade and so that the sod after placement will be flush with or slightly below the adjacent final ground line.
216.03.3 Ground Preparation and Fertilizing . After the area has been graded as
required, the specified types and quantities of fertilizers shall be uniformly spread and incorporated in accordance with Section 21 2 for standard ground preparation. The prepared area shall be at an approved mois ture content and shall present a smooth, uniform surface with reasonably close conform ity to the specified lin e, grade, and cross section. After approval by the Engineer of the prepared and fertilized area, sodding shall follow immediately.
216.03.4 Planting Sod . The sod shall be placed on the prepared surface with edges in
close contact and starting at the lowest point and working upward. Cracks between blocks of sod shall be filled with small pieces of fresh sod, and all cracks too small for sod shall be filled by a light dressing of appr oved soil. The entire sodded area shall then be compacted and watered to the satisfaction of the Engineer. Light rollers, hand tamps, or other approved equipment shall be used for compacting. If the Engineer deems that in a particular ar ea the sodding might slide due to the height and slope of the surface or nature of the soil, the sod shall be "pegged" with wooden pegs driven through the sod blocks into firm earth. Pegs shall be at intervals deemed suitable to hold the sod in place.
216.03.5 Limitations . Solid sodding shall be performed only when weather and soil
conditions are deemed by the Engineer to be suita ble for proper placement.
216.03.6 Plant Establishment. Plant establishment shall consist of preserving, protecting, replacing, watering, mowing, and other work necessary to keep the sod in a
satisfactory condition at all times until final acceptance. A satisfactory growth of solid sodding shall be understood to mean a healthy, living, and growing grass turf, unless in the dormant season, which has been planted on an approved prepared foundation and has been maintained in accordance with the requirements of these specifications.
216.04 Method of Measurement . Solid sodding will be measured by the square yard.
If solid sodding is required by the contract, or ordered by the Engineer, on a section graded under a previous contract, required excavation, exclusive of trenching out and fine grading, will be measured under the appropriate excavation item of the contract, or as extra work. Water ordered will be measured and paid for as prescribed in Subsection 219.04.
216.05 Basis of Payment . Solid sodding will be paid for at the contract unit price per
square yard, which price shall be full compensation for all labor, equipment, materials, tools, ground preparation, fertilization, a nd all incidentals necessary to complete the work. Payment will be made under: 216-A: Solid Sodding - per square yard 216-B: Solid Sodding, Kind - per square yard SECTION 217 - DITCH LINER
217.01 Description . This work consists of furnishing, placing, and maintaining a ditch
liner of jute mesh, excelsior blanket, erosion control blanket or erosion control fabric on seeded, or other designated areas in acco rdance with the plans and specifications. Asphalt-coated fiber glass roving meeting the requirements of Section 218 may be substituted for ditch liner. Any substituted fiber glass roving will be measured by the square yard and paid at the contract bid price for ditch liner.
217.02 Materials . The type of material used for the ditch liner shall be at the option of
the Contractor unless otherwise specified. Jute mesh, excelsior blanket, erosion control blanket and erosion control fabric shall meet the requirements of Subsection 715.09.
217.03 Construction Requirements .
217.03.1 General . The areas to be covered shall be prepared, fertilized, vegetated and
left in a smooth uniform condition, free of stones, lumps, roots or other material that will prevent the ditch liner from being in contact with the underlying soil. Immediately following the planting operation, the ditch liner shall be installed by unrolling it in the direction of water flow and draping it loosely, without folds or stretching, so that continuous ground contact is maintained. The mulch material shall be omitted from areas receiving the ditch liner. When two or more strips are required to cover a ditch area, the longitudinal laps shall be a minimum of four inches with the upgrade width on top. Transverse laps shall be a minimum of 12 inches with the upgrade section on top. The end of the material at the beginning and ending of each area to be covered shall be folded and placed in a vertical anchor trench at least six inches deep, and stapled in the trench on six-inch centers, backfilled, and tamped. When directed, edges subject to scour shall be buried similarly. On the upgrade end, reinforce with a row of staples on six-inch centers about one foot below the anchor trench. All transverse laps shall be stapled on
