120-1.2 Earthwork Categories: Performance of Earthwork Operations will fall into one <br /> of the following Earthwork Categories: <br /> 120-1.2.1 Earthwork Category 1: Includes the earthwork and related <br /> operations associated with the construction of sidewalks and bike paths along with any <br /> drainage structures associated with these facilities. <br /> 120-1.2.2 Earthwork Category 2: Includes the earthwork and related <br /> operations associated with the construction of turn lanes and other non-mainline traffic lanes, <br /> widening, roadway shoulders, concrete box culverts, retaining walls, and other drainage <br /> structures on the non-mainline pavement. <br /> 120-1.2.3 Earthwork Category 3: Includes the earthwork and related <br /> operations associated with the construction of new mainline pavement, along with concrete <br /> box culverts, retaining walls, and other drainage structures on the mainline pavement. <br /> 120-2 Classes of Excavation. <br /> 120-2.1 Excavation of Unsuitable Material: Excavation of unsuitable material <br /> consists of the removal of muck, clay, rock or any other material that is unsuitable in its <br /> original position and that is excavated below the finished grading template. For stabilized <br /> bases and sand bituminous road mixes, the finished grading template is the top of the <br /> finished base, shoulders and slopes. For all other bases and rigid pavement, the finished <br /> grading template is the finished shoulder and slope lines and bottom of completed base or <br /> rigid pavement. <br /> 120-2.2 Lateral Ditch Excavation: Lateral Ditch Excavation consists of all excavation <br /> of inlet and outlet ditches to structures and roadway, changes in channels of streams, and <br /> ditches parallel to the roadway right-of-way. Dress lateral ditches to the grade and cross- <br /> section shown in the plans. <br /> 120-2.3 Channel Excavation: Channel Excavation consists of the excavation and <br /> satisfactory disposal of all materials from the limits of the channel as shown in the plans. <br /> 120-2.4 Excavation for Structures and Pipe: Excavation for Structures consists of <br /> the excavation for bridge foundations, box culverts, pipe culverts, storm sewers and all other <br /> pipe lines, retaining walls, headwalls for pipe culverts and drains, catch basins, drop inlets, <br /> manholes, and similar structures. <br /> 120-3 Excavation Requirements. <br /> 120-3.1 Excavation and Replacement of Unsuitable Materials: Where rock, muck, <br /> clay, or other material within the limits of the roadway is unsuitable in its original position, <br /> excavate such material to the cross-sections shown in the plans or indicated by the Engineer, <br /> and backfill with suitable material. Shape backfill materials to the required cross-sections. <br /> Where the removal of plastic soils below the finished earthwork grade is required, meet a <br /> construction tolerance of ± 0.2 foot in depth and ± 6 inches (each side) in width. <br /> 120-3.2 Lateral Ditch Excavation: Excavate inlet and outlet ditches to structures and <br /> roadway, changes in channels of streams and ditches parallel to the roadway. Dress lateral <br /> ditches to the grade and cross-section shown in the plans. <br /> 120-3.3 Channel Excavation: Excavate and dispose of all materials from the limits of <br /> the channel as shown in the plans. Excavate for bridge foundations, box culverts, pipe <br /> culverts, storm sewers and all other pipe lines, retaining walls, headwalls for pipe culverts and <br /> drains, catch basins, drop inlets, manholes, and similar structures. <br /> 01025-25 Technical Specifications <br /> FAPublic Works\ENGINEERING DIVISION PROJECTS\08456-Old Dixie Hwy Sidewalk(38th Ln-45th St)\Admim\bid <br /> documents\Master Contract Documents\Technical Specifications.doc <br />
