City of Sunny Isles Beach NE 174th Street Roadway Improvements 329200 - 5 Sodding 3.02 PREPARATION: A. Excavation, Backfilling, and Fine Grading: Areas where sod is to be planted shall have the top three inches of material removed and replaced by a two inch blanket of planting soil prior to sodding. Remove stones, sticks, rubbish, and other extraneous matter. All rough areas and voids shall be eliminated during final grading in order to have a smooth and even grade. B. Fertilizer Application: 1. The rate or application for dry fertilizer shall be 16 pounds per 1000 sq. ft. if 6-6-6 is used and 12 pounds per 1000 sq. ft. if 8-8-8 is used. Fertilizer shall be spread uniformly over areas to be sodded, by use of a distribution device calibrated to distribute the specified quantities. 2. Disc-spread the fertilizer into the soil to a depth of three inches. 3.03 INSTALLATION: A. Placement of sod: The sod shall be moist, and shall be placed on a moist bed of planting soil. Pitchforks shall not be used in handling sod, and dumping from vehicles shall not be permitted. The sod shall be carefully placed by hand, edge to edge in rows at right angles to the slope, commencing at the base of the area to be sodded and working upward. The sod shall be immediately pressed firmly into contact with a 500 pound hand roller, or any other equipment approved by the Architect that will produce a 90 pound per square inch compression grading. The rolling operation shall provide a true and even surface and insure knitting without displacement of sod or deformation of the surfaces of the sodded area. Hand tamp those areas inaccessible to the roller. The edges of the sodded area shall be staggered in a corresponding manner, providing the offset along the edge does not exceed 6 inches. All vertical edging adjacent to sodded areas shall be tamped so as to produce a featheredge. B. On slopes having a ratio of one in three or greater, peg the installed sod into place with not less than two stakes per square yard. C. Immediately after completing placement of sod, begin watering operation. Water shall be applied in the amount necessary to keep the sod moistened to the full depth of the root zone for a period of not less than two weeks. D. After the initial two week watering period, apply water as needed, to maintain rooting and growth for the duration of the Contract until beneficial occupancy. E. Clean-up: After the sodding operations have been completed, all debris, fertilizer bags, pallets and other construction debris created by the subcontractor shall be removed from the project. Any paved areas, including curbs and sidewalks which have been strewn with soil, sod waste, or fertilizer shall be thoroughly swept. F. Weeding: In the event that weeds or other undesirable vegetation become prevalent to such an extent that whether cut or uncut they threaten to smother the grass species, they shall be removed as directed by the Landscape Architect. If necessary, replace as needed. G. Sanding: If, in the opinion of the Architect the sod bed, after planting, is in need of an application of sandy top-dressing, for reasons of irregularities or shrinking joints, the subcontractor shall immediately perform this function.
