SODDING Preparation of Area to be Sodded: The ground which is to receive sod shall have been graded to proper elevations (2" below sodded grade) to match pre -construction conditions or proposed grades. All disturbed swales and ditches shall have been restored to their pre -construction condition or better. The pre -construction grade shall be maintained and the prepared soil shall be loose and reasonable smooth. It shall be reasonable free of large clods, roots, patches of existing grass, and other material which will interfere with the sod -laying operations or subsequent mowing and maintenance operations. Laying of Sod: Sod shall be installed in all areas so designated by Engineer. Sod shall be carefully placed so that each piece abuts flush to all surrounding sod, regardless of whether surrounding sod is new or existing. Where new sod is to be placed adjacent to existing sod, the new sod must be cut in to match the elevation of the existinn sod. Uneven sod which might cause mowing problems will be rejected. New sod laid on top of existing sod will also be rejected. All sod placed on steep slopes (greater than 1:1) shall be pinned with a wooden pin to keep it in place. Rolling: immediately after completion of the sod laying, the entire sodded area shall be rolled thoroughly with the equipment specified. At least two trips over the entire area will be required. Watering: Newly -sodded areas are to be watered by Contractor as necessary to keep sod alive until the Contractor is closed out. Dead sod shall be replaced by Contractor prior to contract closeout. SEEDING Sequence of Operations: The operations involved in the work shall proceed in the following sequence: preparation of the ground, seeding, spreading, and cutting in mulch. Preparation of Area to be Seeded: The ground over which the seed is to be sown shall be prepared by disk -harrowing and thoroughly pulverizing the soil to a suitable depth. The prepared soil shall be loose and reasonably smooth. It shall be reasonable free of large clods, roots, and other material which will interfere with the work or subsequent mowing and maintenance operations. Application of Seed: While the soil is still loose, the seed shall be scattered uniformly over the grassing area and immediately mixed into the seed bed to a depth of one-half inch. Unless other types of seed are called for, permanent -type grass seed shall be a mixture of 20 parts of Bermuda seed and 80 parts of Pensacola Bahia seed. Quick -growing type grass seed shall be a species which will provide an early ground cover during the particular season when planting is done and will not later compete with permanent grass. The separate types of seed used shall be thoroughly dry -mixed immediately before sowing. Seed which has become wet shall not be used. Mulching: When mulching is called for, approximately two inches, loose thickness, of the mulch material shall then be applied uniformly over the seeded area, and the mulch material cut into the soil with the equipment specified, so as to produce a loose mulched thickness of three to four inches. Care shall be exercised that the materials are not cut too deeply into the soil. No artificial watering of the mulch shall be done before it is applied. 02.485-3 DADIVISION 2102485 Grassing.doc
