Section 627 — Sod

Description

627.01This work consists of providing and placing living sod of perennial turf- forming grasses.

Material

627.02Conform to the following Subsections: Agricultural limestone 713.02 Fertilizer 713.03 Pegs for sod 713.10 Sod 713.09 Water for vegetation 725.01(b)

Construction Requirements

627.03General. Move and place sod during dry weather and on dry, unfrozen ground. Avoid erosion when watering. 627.04 Delivery. Provide at least 3 days’ notice before cutting sod. Obtain approval of the sod in its original position before cutting. Do not deliver sod until the soil is prepared. 627.05 Preparing the Soil. Clear and grade the surface. Cultivate, disk, harrow, or otherwise loosen the grade to a depth of at least 4 inches. Finish the surface to a smoothness comparable to hand raking. Remove surface stones not passing a 1 -inch sieve. Remove sticks, stumps, and other surface debri s that interfere with sod placement or subsequent growth. Place topsoil according to Section 624 as shown in the plans. Apply fertilizer and agricultural limestone uniformly over the sodding area. Mechanical spreaders or blower equipment may be used. Disk or till the fertilizer and limestone into the soil to a depth of 4 inches. Moisten the prepared soil.

627.06Placing Sod. Place sod within 24 hours after cutting or within 5 days after cutting if the sod is stored in moist stacks, grass- to-grass and roots -to-roots. Protect sod against drying and from freezing.

(a)Solid sod. Place sod perpendicular to drainage flows. Place sections of solid sod edge to edge with staggered joints. Plug openings with sod or fill openings with acceptable loamy seeded topsoil. Roll or tamp sod to eliminate air pockets and provide an even surface. On slopes 1V:2H or steeper and in channels, peg sod on 24 -inch centers after rolling or tamping. Drive pegs flush with the sod bed surface.

(b)Spot sod. Place sod blocks. Roll or tamp the blocks into the soil until the sod surfaces are slightly below the surrounding ground surface. Blend final grades with existing adjacent areas. Leave the entire area drainable and without abrupt changes in slope.

627.07Maintaining Sodded Areas. Water sod to a depth of 4 inches after placing and keep moist. Protect newly sodded areas using approved methods. Do not allow vehicles or equipment on newly sodded areas. Mow sodded areas and repair or replace sodded areas that are damaged or fail to show a uniform growth of grass. Maintain sodded areas and replace nonliving sod until final acceptance of the project.

627.08Acceptance. Material for sod (including lime and fertilizer) will be evaluated under Subsections 106.02 and 106.03. Placing sod will be evaluated under Subsections 106.02 and 106.04. Topsoil will be evaluated under Section 624.

Measurement

627.09Measure the Section 627 pay items listed in the bid schedule according to Subsection 109.02 .

Payment

627.10The accepted quantities will be paid at the contract price per unit of measurement for the Section 627 pay items listed in the bid schedule. Payment will be full compensation for the work prescribed in this Section. See Subsection 109.05 . Progress payments will be paid as follows:

(a)75 percent of the pay item amount will be paid after initial placement of sod.

(b)The remaining 25 percent of the pay item amount price will be paid after the final ac ceptance.
