Examine areas to receive plants for compliance with requirements and conditions affecting <br />installation and performance. <br />1. Verify that subgrades are correct prior to spreading topsoil or spreading amendments. <br />2. Conduct water percolation tests to verify that planting depths and drainage will meet the <br />needs of the plants that have been selected. Inform the Architect of any drainage issues. <br />3. Verify that no foreign or deleterious material or liquid such as paint, paint washout, <br />concrete slurry, concrete layers or chunks, cement, plaster, oils, gasoline, diesel fuel, paint <br />thinner, turpentine, tar, roofing compound, or acid has been deposited in soil within a <br />planting area. <br />4. Along roadways and in landscape islands, remove gravel and asphalt from landscape beds. <br />5. Do not mix or place soils and soil amendments in frozen, wet, or muddy conditions. <br />6. Suspend soil spreading, grading, and tilling operations during periods of excessive soil <br />moisture until the moisture content reaches acceptable levels to attain the required results. <br />7. Uniformly moisten excessively dry soil that is not workable and which is too dusty. <br />B. Proceed with installation only after unsatisfactory conditions have been corrected. <br />C. If contamination by foreign or deleterious material or liquid is present in soil within a planting <br />area, remove the soil and contamination as directed by Architect and replace with new planting <br />soil. <br />3.2 PREPARATION <br />A. Protect structures, utilities, sidewalks, pavements, and other facilities and turf areas and existing <br />plants from damage caused by planting operations. <br />B. Install erosion-control measures to prevent erosion or displacement of soils and discharge of soil- <br />bearing water runoff or airborne dust to adjacent properties and walkways. <br />C. Lay out individual tree and shrub locations and areas for multiple plantings. Stake locations, <br />outline areas, adjust locations when requested, and obtain Architect's acceptance of layout before <br />excavating or planting. Make minor adjustments as required. <br />DocuSign Envelope ID: 7D9ACD4F-8F6C-42B6-9ADB-C60032DB6D03
