c.Agricultural Ground Limestone .......................................................... 1081.07
d.Fertilizer ............................................................................................. 1081.08 CONSTRUCTION REQUIREMENTS
252.03 Ground Preparation. The area to be sodded shall be finished
according to Section 212 before sodding operations are begun. Immediately prior, but not in excess of 24 hours before the sod is placed, the soil surface shall be worked until it is free from debris, washes, gullies, clods and stones. The surface shall be worked to a depth of not less than 3 in. (75 mm) with a disk, tiller or other equipment approved by the Engineer. Prepared surface shall be finished to a fine smooth finish free of irregularities. Finished ground elevations shall allow for the thickness of sod to match grade of existing turf or structures. All soil surfaces shall be moist when the sod is placed. When directed by the Engineer, the Contractor shall be required to apply water to dry soil surfaces at a minimum rate of 1 gal/sq yd (5 L/sq m) immediately prior to placing the sod. When specified, agricultural ground limestone and fertilizer nutrients shall be applied at the designated rates over the areas to be sodded. Art. 252.03 Sodding When fertilizer is specified, 180 lb (210 kg) of fertilizer nutrients per acre (hectare) shall be applied over the areas to be sodded at a 1:1:1 ratio as follows. Nitrogen Fertilizer Nutrients 60 lb/acre (70 kg/ha) Phosphorus Fertilizer Nutrients 60 lb/acre (70 kg/ha) Potassium Fertilizer Nutrients 60 lb/acre (70 kg/ha)
252.04 Sodding Time. Sod shall be placed when the ground is in a workable
condition and temperatures are less than 80 °F (26 °C). Sod shall not be placed when the sod or ground surface is frozen. Sod shall not be placed during the months of July and August.
252.05 Transportation. All sod shall be properly protected during
transportation to maintain it in a live, healthy condition. Sod cut for more than 48 hours shall only be used with the approval of the Engineer. Any sod that has dried out, has heated to over 100 °F (38 °C), or is frozen prior to placing will be rejected and shall be immediately removed from the jobsite by the Contractor.
252.06 Placing Sod. The sod shall be placed on the prepared surface with
the edges in close contact and alternate courses staggered. In ditches, the sod shall be placed with the longer dimension perpendicular to the flow of water in the ditch. On slopes, starting at the bottom of the slope, the sod shall be placed with the longer dimension parallel to the contours of the ground. The exposed edges of sod shall be buried flush with the adjacent soil. On slopes where the sod may be displaced during sodding operations, the workmen shall work from ladders or treaded planks.
252.07 Staking Sod. The sod shall be staked on all slopes of 1:2 (V:H) or
steeper. Sod shall be staked with not less than four stakes per sq yd (sq m) with at least one stake for each piece of sod. Stakes shall be a minimum of 6 in. (150 mm) long. Stakes shall be installed so that they hold the sod firmly in place yet present no danger to pedestrians or mowing crews. The type of stake and the method of installation shall meet the approval of the Engineer.
252.08 Sod Watering. Within two hours after the sod has been placed, water
shall be applied at a rate of 5 gal/sq yd (25 L/sq m). Additional water shall be applied every other day at a rate of 3 gal/sq yd (15 L/sq m) for a total of 15 additional waterings. During periods exceeding 80 °F (26 °C) or subnormal rainfall, the schedule of additional waterings may be altered with the approval of the Engineer. The Contractor shall have on hand enough equipment to completely water all sodded areas in two days at the watering rates specified above. The Engineer will make periodic checks of the Contractor’s watering equipment to determine its adequacy and operating condition. All watering described shall be done with a spray application. An open end hose will not be acceptable. The method of watering shall meet the approval of the Engineer. Sodding Art. 252.13
252.09 Supplemental Watering. During periods exceeding 80 °F (26 °C) or
subnormal rainfall, supplemental watering may be required after the initial and additional waterings. Supplemental watering shall be performed when directed by the Engineer. Water shall be applied at the rate specified by the Engineer within 24 hours of notice.

With every shipment of salt tolerant sod, the Contractor shall provide to the Engineer a letter of certification from an authorized representative of the nursery stating that the seed mixture used in the sod conforms to the specifications.
252.12 Method of Measurement. Sodding will be measured for payment in
place and the area computed in square yards (square meters). To be acceptable for final payment, the sod shall be growing in place for a minimum of 30 days in a live, healthy condition. When directed by the Engineer, any defective or unacceptable sod shall be removed, replaced, and watered. Sod watering will not be measured for payment. Supplemental watering will be measured for payment in units of 1000 gal (1000 L) of water applied on the sodded areas. Waterings performed in addition to those required by Article 252.08 or after the 30 day establishment period will be considered as supplemental watering. Fertilizer and agricultural ground limestone will be measured for payment according to Article 250.09.
