O L 5 CLEARING AND GRUBBING SCOPE: The work covered by this section shall include removal of trees, brush and other obstacles from the street right-of-way and from the site proper if so directed by the owner. METHOD: Unless otherwise directed by the owner, all trees, brush, roots, weeds, grass and other obstacles to construction shall be removed from the street right-of-way prior to grading operations. All undesirable soils such as slimes, muck or other unsuitable material shall be completely removed from the proposed street areas and disposed of off -site or as directed by the owner and/or engineer. DISPOSAL- Trees, roots, seeds, and other burnable material may be piled on the site and burned, but only with the Owner's consent, and in the area designated by the Owner. All other materials must be hauled away from site and disposed of at the Contractor's expense. Care should be taken to secure necessary burning permits, etc. Such permits are the sole responsibility of the Contactor and any instructions by the Owner and/or Engineer does not relieve the Contractor of the responsibility for containing the burning in a safe manner. Damages resulting from said burning to the overall site or neighboring lands or property are the Contractor's responsibility. DEPTH OF REMOVAL: All trees, roots, and other obstacles shall be removed to a depth of at least one (1) foot below the subgrade with the exception of slimes, muck or other unsuitable materials which shall be completely removed from road right-of-way. GROUNDWATER: Contractor may be required to dewater to construct improvements. The Contractor shall use waterproof base or underdrains, as required by the Final Authority, to protect the integrity of the construction when high-water tables are within eighteen (18) inches of the roadway base course. When any additional costs are anticipated, the Engineer shall be notified prior to proceeding to verify method(s) to be utilized, change order(s) submitted and approval by the Owner and Engineer. GRADING AND EXCAVATION SCOPE: The work covered by this section shall include all excavation and embankment. Specifically this includes the excavation and embankment required to rough grade the streets, finishing the backslopes from the street to the property line and lot grading, BUT may be extended to Include canals, ditches or lakes when directed by the plans. MATERIALS: The material used for fill shall be approved by the Engineer. Material obtained from on -site shall be used whenever possible. No material shall be hauled from the site without the approval of the Owner and/or Engineer. CONSTRUCTION METHODS GRADING TOLERANCE: Areas, to be graded shall be brought to within one -tenth (0.10) of a foot of elevation shown on the plans or as directed by the Engineer. Material for grading shall be placed in layers not to exceed eight (8) inches. Each layer shall be spread evenly and compacted to an average of 98 % of maximum density In accordance with AASHTO T99. The minimum density acceptable at any location will be 96%. STABILIZATION SCOPE: The work covered by this section consists of stabilizing beneath the entire paved roadway. The limits of stabilization shall be in accordance with the "Typical Roadway Section" shown on the plans. This work shall be done after all subsurface work has been completed. MATERIALS: The material used for stabilization shall consist of suitable roadway materials, such as he local sandy, clay, limerock screenings, in accordance with requirements set forth by the F.D.O.T. Standard Specifications. CONSTRUCTION METHODS: The stabilization material shall be uniformly mixed with the virgin ground to the depth and bearing value indicated in the Typical Roadway Section. Mixing shall be accomplished by use of rotar, t>;lers or other methods approved by the Engineer. Stabilization MAY NOT commence on any area that has not first been cleared and grubbed according to the previous section. The stabilized area shall be compacted throughout it's entire thickness, per "Typical Roadway Section". MAINTENANCE OF STABILIZED AREA: After the stabilization has been completed, the Contractor shall maintain roadway free from damage, ruts, etc., caused by hauling or erosion or other causes. The required Bearing Value MUST be maintained at all times in preparation for the base course. BASE Scope: The work covered by this section consists of the construction of a roadway base which is composed of limerock, shell, asphalt or soil cement as indicated on the "Typical Roadway Section" shown on the plans. The base shall be constructed on a prepared subgrade where applicable in accordance with these specifications and with the lines, grades and typical cross sections shown on the plans and details. MATERIAL& The materials used shall conform to the requirements set by the Florida Department of Transportation "Standard Specifications For Road and Bridge Construction" latest edition. EQUIPMENT: All equipment, necessary for the proper construction of this work shall be on the project in good mechanical condition. TRANSPORTATING BASE MATERIAL; The base material shall be transported to the point where it is to be used, over base previously placed. NO HAULING OVER THE SUBGRADE shall be allowed without the approval of the Engineer. SPREADING BASE MATERIAL; The base material shall be spread uniformly with approved equipment. Ali non -uniform material shall be removed and replaced. Roadway base with specified thickness in excess of 6" shall be constructed in two courses. COMPACTING BASE MATERIAL: After the spreading is completed, the entire surface shall be finished and shaped so as to produce the exact grade and cross section required by the plans after compaction. When applicable base material does not have the proper moisture content to ensure the required density, wetting to drying will be required. If moisture is added, it shall be uniformly mixed for the FULL DEPTH of the base course. During the final compacting operations on limerock or shell base, all areas must be finished to grade before density tests are performed. Diligence shall be used to avoid mixing the subgrade material into the base material. If this occurs, the Contractor shall remove and replace with clean materials at his expense. If cracks or checks appear in the base course, before or after priming, which, in the opinion of the Engineer, would impair the structural efficiency of the base course, the Contractor shall remove such cracks or checks by reworking and the cost of such removal shall be the Contractor's responsibility. 1.
