Specifications include, but are not limited to: 1. Underground Irrigation Systems. Section 201.3, “Sprinkler Systems”, delete the section and replace with the following: Properties within the project may have underground irrigation systems (lawn sprinklers) which conflict with new construction. Contractor shall remove such components as needed during construction of the project, salvaging all sprinkler heads, valves and operators, and pertinent controllers/equipment to the property owner, where possible. Portions of underground irrigation systems not in conflict with new construction shall be protected from damage and shall remain in place. The Contractor shall exercise caution, through communication with the property owner, to insure that work completed as part of the project does not adversely affect the operation of existing irrigation system(s) on private property, behind the right-of-way. The Contractor is to coordinate final site restoration with the property owner, such that they are afforded the opportunity to replace the irrigation system prior to sod/seed installation. All work associated with this item will not be paid for separately, but considered SUBSIDIARY to the “Site Clearing” bid item, or equivalent equal. 2. Tree Removal. Section 202.2, “Hedge and Tree Removal”, delete the second paragraph and replace with the following: Unless otherwise indicated on the plans or in the “Project Specific” Special Provisions, all projects shall include bid items for “Large Tree Removal” and “Small Tree Removal”, if applicable. Any tree 15 inches in diameter or larger, as measured 24 inches above the natural ground level shall be considered a “Large Tree” for payment purposes. Any tree less than 15 inches in diameter, as measured 24 inches above natural ground level shall be considered a “Small Tree” for payment purposes. All tree removal will be approved by the Project Engineer prior to completing the work. Materials to be used for geogrid reinforced base construction shall consist of virgin crushed stone, recycled Portland cement concrete, or a blend of recycled Portland cement concrete and Reclaimed Asphalt Pavement (RAP). This blend is not to exceed 50% RAP and shall be tested by use of an asphalt burn off oven to ensure compliance.
