SECTION 02312 - SWALE CONSTRUCTION <br />PART 1 - DESCRIPTION: <br />A. Find grading of swaled shall be accomplished after the existing ground has been <br />excavated and compacted to within + 0.2 ft. of the design elevations. Fine grading <br />of the swale areas will be done by motor grader unless otherwise approved or <br />directed by the Engineer. Hand dressing will not be required except where shown <br />on the Drawings or in confined areas where equipment operation is restricted <br />B. The Contractor shall maintain and keep open and free from leaves, sticks, rubble, <br />and other debris, all swaled graded by him until final acceptance of the work. <br />C. The finished grade shall be competed and shaped to a surface which varies no <br />more than 0.1 foot above or below the Plan elevations except that, adjacent to <br />pavement, grates, or sidewalk, the swale shall be graded to match the edge of the <br />pavement, grate or sidewalk. <br />D. In areas where sodding is required, finished soil grade shall be set 0.2 foot below <br />the plan elevation to compensate for sod thickness. <br />E. Compaction to a specific density will not be required unless so directed by the <br />Engineer. However, swales shall be compacted to a firm, even surface true to <br />grade and cross section. All swales must be rolled. <br />F. Fine grading of the swale areas shall preferably be done prior to paving the <br />asphalt wearing course. If the'Contractor chooses to fine grade the swale areas <br />subsequent to paving, he must exercise extreme care when dressing areas adjacent <br />to pavement areas to avoid damage to the pavement. No handling of swale <br />material shall be permitted onthe pavement surface. <br />***END OF SECTION*** <br />02312-1 <br />
