570-3Construction Methods

570-3.1General: Remove all construction debris in performance turf areas. Install

performance turf at the ea rliest practical time for erosion control and establishment . Shape the areas to be planted to the plan typical sections and lines and grade shown in the Plans. Except in areas where the Contract Documents requires specific types of turf to match adjoining private property, any species of turf designated in Section 981 may be used. All of the permanent performance turf material shall be in place prior to final acceptance. The Department will only pay for replanting as necessary due to factors determine d by the Engineer to be beyond control of the Contractor. Install all performance turf on shoulder areas prior to the placement of the friction course on adjacent pavement.

570-3.2Seeding: At the Contractor’s option, wildflower seed may be included in the

performance turf seeding operation or performed separately from the performance turf seeding. Seed must produce visible seedlings within 45 days of planting. Use of compost meeting the requirements of Section 987 as mulch is acceptabl e unless otherwise specified.

570-3.3Sod: Place the sod on the prepared surface, with edges in close contact. Do not

use sod which has been cut for more than 48 hours. Place the sod to the edge of all landscape areas as shown in the Plans and the Standard Plans. Place rolled sod parallel with the roadway and cut any exposed netting even with the sod edge. Monitor placed sod for growth of exotic or invasive pest plants and noxious weeds. If exotic or invasive pest plants and/or noxious weeds manifest themselves within 30 days of placement of the sod during the months April through October, within 60 days of placement of the sod during the months of November through March treat affected areas by means acceptable to the Department at no expense to the D epartment. If pest plants and/or noxious weeds manifest themselves after the time frames described above from date of placement of sod, the Engineer, at hi s sole option, will determine if treatment is required and 811 FY 2023-24 Return to Table of Contents whether or not the Contractor will be comp ensated for such treatment. If compensation is provided, payment will be made as Unforeseeable Work as described in 4 -4. Remove and replace any sod as directed by the Engineer.

570-3.4Hydroseeding: Use equipment specifically designed for mixing the mulch, seed,

fertilizer, tackifier and dye, and applying the slurry uniformly over the areas to be hydroseeded. Use mulch that does not contain reprocessed wood or paper fibers. Ensure that 50% of the fibers will be retained on a twenty -five mesh screen. Mix fertilizer as required into the hydroseeding slurry. Ensure that the dye does not contain growth or germination inhibiting chemicals. When polyacrylamide is used as part of hydroseeding mix, only anionic polymer formulation with free acrylamide mon omer residual content of less than 0.05% is allowed. Cationic polyacrylamide shall not be used in any concentration. Do not spray polyacrylamide containing mixtures onto pavement. These may include tackifiers, flocculants or moisture - holding compounds.

570-3.5Bonded Fiber Matrix (BFM): Meet the minimum physical and performance

criteria of this Specification for use of BFM in hydroseeding operations or temporary non - vegetative erosion and sediment control methods. Provide evidence of product performance testing, manufacturer’s certification of training and material samples to the Engineer at least 7 calendar days prior to installation. Provide documentation to the Engineer of manufacturer’s testing at an independent laboratory, demonstrating superior pe rformance of BFM as measured by reduced water runoff, reduced soil loss and faster seed germination in comparison to erosion control blankets. Use only BFMs that contain all components pre -packaged by the manufacturer to assure material performance. Deli ver materials in UV and weather resistant factory labeled packaging. Store and handle products in strict compliance with the manufacturer’s directions. When polyacrylamide is used as part of hydroseeding mix, only anionic polymer formulation with free ac rylamide monomer residual content of less than 0.05% is allowed. Cationic polyacrylamide shall not be used in any concentration. Do not spray polyacrylamide containing mixtures onto pavement. These may include tackifiers, flocculants or moisture - holding co mpounds. Meet the following requirements after application of the formed matrix: Ensure that the tackifier does not dissolve or disperse upon re -wetting. Ensure that the matrix has no gaps between the product and the soil and that it provides 100% coverage of all disturbed soil areas after application. Ensure that the matrix has no germination or growth inhibiting properties and does not form a water -repelling crust. Ensure that the matrix is comprised of materials which are 100% biodegradable and 100% beneficial to plant growth. Mix and apply the BFM in strict compliance with the manufacturer’s recommendations. Apply the BFM to geotechnically stable slopes at the manufacturer’s recommended rates. Degradation of BFM will occur naturally a s a result of chemical and biological hydrolysis, UV exposure and temperature fluctuations. Re -application, as determined by the 812 FY 2023-24 Return to Table of Contents Engineer, will be required if BFM -treated soils are disturbed or water quality or turbidity tests show the need for an additional application.

570-3.6Watering: Water all performance turf areas as necessary to produce a healthy

and vigorous stand of turf. Ensure that the water used for turf irrigation meets the requirements of Section 983.

570-3.7Fertilizing: Fertilize as necessary to promote turf growth and establishment

based on soil testing . Refer to Section 982 for fertilizer rates. For bid purposes, base estimated quantities on an initial application of 265 lb/acre and one subsequent application of 135 lb/acre of 16 -0-8.

570-3.8Shoulder Treatment: Provide soil for shoulder treatment in accordance with

Standard Plans, Index 570-010. Soil needed for these purposes will be included in the corresponding Pay Item.

570-4Turf Establishment

Perform all work necessary, including watering and fertilizing, to sustain an established turf, free of noxious weeds , at no additional expense to the Department. Provide the filling, leveling, and repairing of any washed or eroded areas, as necessary. Established turf is defined as follows:

pulled from the soil by hand).

Contractor equipment.

Monitor turf areas and remove all competing vegetation, exotic or invasive pest plants, and noxious weeds (as listed by the Florida Exotic Pest Plant Council, Category I “List of Invasive Species”, Curr ent Edition, https://www.fleppc.org ). Remove such vegetation regularly by manual, mechanical, or chemical control means, as necessary. When selecting herbicides, pay particular attenti on to ensure use of chemicals that will not harm desired turf or wildflower species. Use herbicides in accordance with 7 -1.7. If at the time that all other work on the project is completed, but all turf areas have not met the requirements for established turf set forth in 570 -4, continuously maintain all turf areas until the requirements for established turf set forth in 570 -4 have been met. During establishment and until the performance turf is established in accordance with this Section, continue the inspection , maintenance , and documentation of erosion and sedimentation control items in accordance with Section 104. Remove and dispos e of all erosion and sedimentation control items after the performance turf has been established. Notify the Engineer, with a minimum of seven calendar days advance notice, to conduct inspections of the performance turf at approximate 90 -day intervals during the establishment period to determine establishment . Results of such inspections will be made available to the Contractor within seven calendar days of the date of inspection. Determination of an established turf will be based on the entire project and not in sections. Upon the determination by the Engineer that the requirements of 570 -4 have been met and an established turf has been achieved and all erosion and sedimentation control items have 813 FY 2023-24 Return to Table of Contents been removed, the Engineer will release the Contractor from any further responsibility provided for in this Speci fication.
