624.01 Description. This item shall consist of furnishing and
placing approved Bermuda sod, fertilizer, and water according to these specifications at locations shown on the plan s, or as directed.
624.02 Materials. (a) The Bermuda sod shall be composed of
either field grown grass or approved nursery grown grass and shall consist of a densely rooted growth of grass substan tially free from noxious weeds and undesirable grasses. The sod shall be sufficiently thick to secure a den se stand of live grass. The sod shall be live, fresh, and uninjured at the time of placing. It shall have a soil mat of sufficient th ickness adhering 501 firmly to the roots to withstand all necessary hand ling. It shall be placed as soon as possible after being cut and shal l be kept moist from the time it is cut until it is placed in its f inal position. The source of field grown sod shall be inspected an d approved by the Engineer before being cut for use in the work. After approval, the area from which the sod is to be harvested shal l be closely mowed and raked as necessary to remove excessive to p growth and debris. Approved devices, such as sod cutters, shall be use d for cutting the sod and due care shall be exercised to retain t he native soil intact. The sod shall be cut in uniform strips. T he width of the sod furnished for use on the project shall be satisfact ory to the Engineer. Rolled sod may be backed with a netting material fo r added strength in handling if necessary.
b.Fertilizer shall be in accordance with Subsection 6 20.02(b).
c.Water shall be in accordance with Subsection 620.02 (f).
624.03 Construction Requirements. (a) Preparation o f Bed.
The area to be sodded shall be dressed to the shape and section shown on the plans and the top and bottom of slopes shall be rounded to a radius of approximately 3 ′ (1 m) unless otherwise directed. The finished slopes shall be free of obj ectionable foreign matter and the top 1" (25 mm) of soil shall be loos ened and finely divided. When directed, areas consisting of poor q uality soil shall be loosened roughly and covered with a layer of top soil not less than 2" (50 mm) in depth. Water may be applied before, during, and after slope preparation, as directed by the Engineer, in order to maintain the desired moisture content in the soil.
b.Fertilization. Immediately before placement of sod, fertilizer shall be broadcast at the rate of 250 pounds per ac re (280 kg/ha) (approximately 1 pound per 19 square yards [1 kg/35 sq m]) of 10- 20-10, or the equivalent amount of plant food, and incorporated into the top 1" (25 mm) of soil.
c.Placement of Sod. The bed shall be in a firm but uncompacted condition with a relatively fine textur e at the time of sodding. Sod shall be moist and shall be placed on a moist earth bed. Sod strips shall be laid along contour lines, by hand, commencing at the base of the area to be sodded and working 502 upward. The transverse joints of sod strips shall be broken, and the sod carefully laid to produce tight joints. At the top of slopes the sod shall be turned into the embankment slightly an d a layer of earth placed over it and compacted to conduct surface wat er over and onto the sod. The sod shall be firmed, watered, and ref irmed immediately after it is placed. The firming shall be accomplis hed by use of a lawn roller or approved tamper, with care being tak en to avoid tearing end strips of sod. When sodding is completed, the sodded areas shall b e cleared of loose sod, excess soil, or other foreign material; a thin application of topsoil shall be scattered over the sod as a top dr essing; and the areas thoroughly moistened. Water shall be applied at a minimum rate of 20.4 M Gallons per acre (188 cu m or 188 kL per ha) or as directed by the Engineer for a period of at least 3 weeks. The Engineer will adjust the amount of water required each week to de duct any rainfall received during the 7 calendar day period prior to the weekly watering. The weekly applications of water and ded uctions for failure to water will not be required from January 1 through March
31.The time required for application of water wil l not be included in the computation of contract time for completion of the project provided all other work under the Contract has been completed. Failure to meet this water application requirement will result in a permanent deduction in payment and /or permanent re covery of payments equal to the minimum bid price established in Subsection 620.05(d) for each M.G. (kL) not applied as directe d in accordance with these specifications. Equipment and methods u sed to place the water shall be in accordance with Subsection 620.03 (f)(4).The Contractor shall maintain sodded areas from the tim e of completion until final acceptance of the project by the Engine er.
d.Restoration. Additional work and materials required because of the Contractor's negligence in maintaining the w ork shall be accomplished at no cost to the Department. When sod is other than nursery supplied, the source field shall be finished according to the agreement between the Con tractor and Owner in a condition, after removal of sod, which i s acceptable to the property owner and conducive to re-establishmen t of turf. A copy of the agreement will be provided to the Engin eer before sod is removed. The agreement will stipulate the final co ndition of the 503 source field. All restoration of the source field shall be done at no cost to the Department.
624.04 Method of Measurement. (a) Solid Sodding will be
measured by the square yard (square meter) of actua l area covered.
b.Water will be measured according to Section 620.
624.05 Basis of Payment. (a) Solid sodding completed and
accepted and measured as provided above will be pai d for at the contract unit price bid per square yard (square met er) for Solid Sodding, which price shall be full compensation for bed preparation; for furnishing and applying fertilizer, topsoil, an d sod; and for all labor, equipment, tools, and incidentals necessary to complete the work.
b.Water will be paid for under Section 620. Payment will be made under: Pay Item Pay Unit Solid Sodding Square Yard (Square Meter)
