604.03 Procedures
a.Preparing Sod Beds: The Contractor shall shape soil on which sod is to be placed to an even surface and grade to such an elevation that sod and adjacent surfaces will have a smooth contour. 604.03 The Contractor shall uniformly apply lime to areas designated to receive sod at the rate of approx - imately 2 tons per acre. The Contractor shall uniformly apply fertilizer to areas designated to receive sod at the rate of 16 1/2 pounds of 15-30-15 fertilizer, or an equivalent quantity of 1-2-1 ratio fertilizer and 10 pounds of ureaformaldehyde per 1,000 square feet. Fertilizer shall have a guaranteed nitrogen, phosphorous, and potassium (N-P-K) analysis as detailed in the plans, with a minimum 30 percent of the nitrogen from a slow release or slowly soluble source. Following application of lime and fertilizer, the Con- tractor shall thoroughly cultivate the soil to a depth of 2 to 3 inches and sprinkle the cultivated area with sufficient water to moisten the cultivated soil.
b.Placing Sod: The Contractor shall not place sod between June 1 and September 1 or at any time the ambient temperature is below 32 degrees F . The Contractor shall not install frozen sod or place sod on frozen soil. Sod shall be placed by hand and joints shall tightly abut without overlapping. Open joints and gaps in sodded areas shall be plugged with sod that has been cut to the size and shape of the opening. The Contractor shall place sod on sloping areas beginning at the bottom of the slope. Sod shall be placed in horizontal strips with the long edges of rectangular pads parallel to the contour. When practicable, horizontal joints shall be reasonably straight and vertical joints shall be staggered. In areas where sod mats may be displaced by foot traffic during sodding operations, ladders or treaded planks shall be used. The Contractor shall anchor sod placed on slopes steeper than 2H:1V with wood stakes driven into the slope and flush with the top of the sod. Stakes shall be at least 8 inches in length with a cross sectional area of approximately 1 square inch. The number and spacing of stakes shall be adequate to hold sod securely in place. The Contractor shall give special attention and care to anchoring sod placed in drainage ditches, channels, and swales. After sod has been placed, any joints and gaps that were too small to be effectively plugged with sod shall be filled with loamy topsoil. The Contractor shall thoroughly water, roll, or tamp sodded areas after installation to press the root system of the sod into full contact with the underlying prepared sod bed. Sodded areas shall be kept watered to promote growth and maintain the life of the sod until final acceptance.
604.04 Measurement and Payment
Sod will be measured in square yards of surface area and will be paid for at the contract unit price per square yard of installed surface area. This price shall include preparing sod beds; furnishing and applying lime, fertilizer, sod, and water; and maintaining sodded areas until final acceptance.
