<br />02480 - 9/12 <br />PART 3 - EXECUTION <br />3.01 The CONTRACTOR shall keep areas free of all trash, debris, loose and excess material, <br />unsecured equipment or tools, etc., which may be subject to theft or vandalism, or which <br />may create a passive or active danger to the safety of the public or an unnecessary <br />eyesore. <br />3.02 The CONTRACTOR shall carefully inspect all plants delivered to the site to verify that they <br />meet the requirements of the Contract as to grading, condition, size, and species. The <br />CONTRACTOR shall reject all plants that do not comply with the requirements. <br />3.03 PREPARATION OF SITE PRIOR TO PLANTING: Before any disturbance of the actual <br />planting areas is performed, the CONTRACTOR and the ENGINEER shall conduct an <br />inspection and evaluation of these sites. Most of the planting areas are sodded to prevent <br />soil erosion on the steep slopes. The CONTRACTOR shall remove a circular area of sod <br />three to four feet in diameter for trees and field-grown shrubs; and two feet in diameter for <br />three-gallon material. All sod shall be removed completely from the area and immediately <br />disposed of off-site. <br />3.04 TREE AND PLANTS PLANTING PITS: The CONTRACTOR shall prepare planting pits as <br />follows. <br />A. Planting pits shall be excavated to the dimensions required to comply with the <br />requirements for soil amendments and to include the following: <br />1. For balled and burlapped trees and shrubs, excavations shall be 24 inches <br />larger in diameter than the root ball. <br />2. For container grown stock, excavate as specified for balled and burlapped <br />stock, adjusted to comply with same diameter dimensions. For three gallon <br />containerized plants, excavate with a hole 12 inches larger in diameter. For <br />one gallon containerized plants, excavate with a hole three inches larger in <br />diameter. <br />3. Stabilize excavations for trees and shrubs with water and allow to percolate out <br />before planting. <br />3.05 TREE AND PLANTS PLANTING: The CONTRACTOR shall plant trees and plants in <br />accordance with industry standards and as follows. <br />A. Set balled and burlapped stock on a six-inch (minimum thickness) layer of <br />compacted planting soil mixture, plumb and in center of pit, with top of ball at same <br />elevation as adjacent finished landscape grades. Remove burlap from sides of balls; <br />retain on bottoms. Set plants in pits at such level that after settlement they bear the <br />same relationship to the finished grade of the surrounding ground as they did in their <br />natural state. Proper turning of all plants to take advantage of the best and most <br />natural growth appearance will be practiced at all times and will be subject to the <br />approval of ENGINEER. Place backfill around base and sides of ball and work each <br />layer to settle backfill and eliminate voids and air pockets. When excavation is <br />approximately one half full, water thoroughly. Repeat watering until no more is <br />absorbed. Water again after placing final layer of backfill. Flush amended soil <br />mixture into place with a slow full hose stream eliminating all air pockets and fill pit to <br />form a broad saucer to surrounding grade. <br />B. Set container grown stock as specified for balled and burlapped stock.
