Restore bottom of excavation to proper elevation with concrete in areas over excavated. <br /> <br />6. Conform to the requirements of SECTION 02221 <br /> <br />D. Demucking: The CONTRACTOR shall remove all organic soils from areas below structures, piping, <br />and road sub grades to the lines and grades indicated. Materials excavated shall not be used for <br />backfill of structures or pipes and shall be placed in random fill zones only. Organic soils may be <br />used for road construction provided such use meets the requirements of SECTION 120, Article 120- <br />5.2 of the Florida Department of Transportation Standard Specifications for Road and Bridge <br />Construction. <br /> <br />H. Excavation of Existing Embankments: The CONTRACTOR shall perform excavation by any <br />method acceptable to the ENGINEER and meeting the requirements of these specifications and <br />the drawings. All materials removed from embankments shall be suitable for reuse as random fill. <br />Excavation limits shall be clearly identified and approved by the ENGINEER prior to initiation of <br />the work. <br /> <br />3.03 EMBANKMENT: <br /> <br />A. Roadway and Access Berm Embankment: The CONTRACTOR shall construct embankments for <br />roadways and access berms in accordance with the requirements of Section 120 of the FDOT <br />Standard Specifications for Road and Bridge Construction. <br /> <br />B. Final Dressing of Slopes: Following completion of embankment placement and compaction, the <br />CONTRACTOR shall grade embankment slopes and adjacent transition areas reasonably smooth and <br />free from irregular surface changes. The CONTRACTOR shall comply with the following: <br />1. Degree of finish shall be that ordinarily obtained from blade grader or similar operations. <br /> <br />2. Provide roundings at bottom of slopes and other breaks in grade. <br /> <br />C. Cross-Sections: Provide field measured cross-sections (one in each direction) of the final <br />embankments/subgrade to the ENGINEER for record purposes. <br /> <br />3.04 <br />1. Structure backfill shall be constructed using material suitable for use in select fill, except that <br />stones or rocks greater than two inches in any dimension shall not be placed within 12 inches <br />of the structure. Lifts shall not exceed 12 inches. <br />BACKFILLING: <br /> <br />A. Pipe Embedment and Backfill: The CONTRACTOR shall perform pipe embedment and backfill as <br />required, shown and specified in accordance with Section 02221. <br /> <br />B. Structures: The CONTRACTOR shall perform backfilling for structures in accordance with the <br />following: <br /> <br />2. Structure backfill shall be compacted to 95 percent maximum dry density (ASTM D-1557). <br /> <br />3. Backfill only after concrete has attained 70 percent design strength. <br /> <br />4. Backfill adjacent to structures only after a sufficient portion of the structure has been built to <br />resist the imposed load. <br /> <br />5. Remove all debris from excavation prior to placement of material. <br /> <br />6. Place backfill in level layers of thickness within compacting ability of equipment used. <br /> <br />
