2. Fill section construction shall start at the lowest plane and progress upward. <br /> 3. When the fill material includes stones, no large stones shall be allowed to nest and all <br /> voids must be carefully filled with small stones or earth and properly compacted. <br /> 4. If necessary, the material shall be brought to the proper moisture content as <br /> determined by the Testing Laboratory by either aerating the material if it is too wet <br /> and if weather conditions permit, or spraying or sprinkling with water if it is too dry. <br /> Each lift shall be mixed thoroughly if drying or wetting is required to insure uniform <br /> distribution of the moisture. <br /> 5. Compaction of fill within 3 ft. of foundation walls shall be performed with manually <br /> operated vibrating place compactors to avoid damaging or displacing new walls. <br /> D. Seasonal Limits: <br /> 1. No frozen fill material shall be placed, spread or rolled in the embankment nor shall <br /> any fill material be placed on frozen ground or during unfavorable weather conditions. <br /> When the work is interrupted by unfavorable weather conditions, fill operations shall <br /> not be resumed until the Testing Laboratory indicates that the moisture content and <br /> density of the previously placed fill are as specified. <br /> 3.6 EARTHWORK TOLERANCE <br /> A. Grade and Alignment Tolerances: <br /> 1. Contractor shall check the work during the grading process with devices satisfactory <br /> to the A/E. The completed subgrade shall conform to Drawings with the following <br /> tolerances: <br /> HORIZONTAL VERTICAL <br /> MEASURE+ MEASURE+ <br /> Cut and Fill Slopes(General Grading): 1.0' 0.10' <br /> Ditch Bottom: 0.5' 0.10' <br /> Cut and Fill Areas in Roadbeds: 0.2' 0.05' <br /> Cut and Fill Areas in Buildings: --- 0.05' <br /> Cut and Fill Areas in Aprons, Yards, etc.: 0.2' 0.05' <br /> 2. Where appropriate, the above tolerances, with the A/E's approval, can be exceeded if <br /> drainage is maintained and the grade is relatively uniform. In all cases the areas shall <br /> drain as intended. <br /> 3.7 GRADING <br /> A. Rough Grading: <br /> ADDENDUM#1 <br /> 1607.001 - ORONO ICE ARENA(CP-2) Page 02200- 12 <br />
