DESCRIPTION
806.01 Description
This work consists of litter/debris removal, mowing, and trimming as specified or as directed by the Engineer for the entire highway right -of-way where accessible (fence -to-fence where applicable), including shoulders for the length of the Project. CONSTRUCTION REQUIREMENTS
806.02 General
Remove litter and debris as directed by the Engineer for the entire construction limits . Dispose of litter and debris in accordance with all applicable permits and s tate and local ordinances. Mowing and vegetation removal work shall consist of m owing and trimming of the right -of-way for vegetation control to maintain a neat aes thetic appearance as directed by the Engineer.
806.03 Definitions
A.Litter Litter refers to a ny object or group of objects foreign to the right -of-way that has been discarded or abandoned and is or may become visible from the edge of the road way or shoulder as a result of mowing, vegetation management, construction, maintenance operations, or traffic. Examples 806.04 897 under this definition include but are not limited to paper, plastic, bottles, cans, wood, tires, portions of tire, and metal products.
B.Mowing Mowing refers to t he work associated with cutting or trimming vegetation , primarily consisting of, but not limited to, grasses, invasive weeds, and small trees or shrubs to provide a consistent and aesthetically pleasing standing vege tation height as directed by the Engineer.
C.Trimming Trimming refers to t he work associated with cutting or trimming vegetation in close proximity to objects or in areas not accessible to conventional mowers in an attempt to prevent damage and provide a consistent vegetation height.
806.04 Time and Frequency
Perform l itter/debris removal a minimum of twice per year or as directed by the Engineer. Perform mowing and trimming a minimum of twice per growing season or as directed by the Engin eer. The Engineer will issue a notice to begin to the Contractor at least 5 days before the date the mowing cycle is to begin. Only perform work during the hours of daylight Monday through Saturday, or as directed by the Engineer. Do not perform this work on Sunday .
806.05 Mowing Operations
Perform all mowing to the satisfaction of the Engineer. Cut standing vegetation to a height of 4 inches while maintaining a consistent vegetation profile within the construction limits. Mow only those areas that are designated as mowable acres, including, if present, a minimum of 5 feet up the back slope from the bo ttom of the ditch, and 5 feet behind all guardrails. To cut vegetation, including small trees, shrubs, and bushes with a stem diameter of up to 1 inch that are inside of and encroaching upon the established mowing limits , use a mower or hand trimming meth ods as directed by the Engineer. Take care not to damage the trees, plants and shrubs that are designated b y the Engineer to remain. Hand t rimming may be required as directed by the Engineer for areas of vegetation inside the designated mowing limits that are not accessible to mechanical mowers. As 806.06 898 work progresses, conduct mowing and trimming to provide a consistent standing vegetation height in all mowing limits adjacent to the roadway. Mow as close as practicable to all fixed objects. Perform h and atop earth berms, within all rip rap areas, and around all fixed objects, including but not limited to earth berms, guardrails, cable rail, utility installations, utility poles, mailboxes, delineators, sign posts, wildflower plots, bridge abutments , and bridge piers. Do not apply chemicals unless authorized by the Engineer. Actual dimensions and mowing limits shall be discussed at the Preconstruction Conference. Mowing for site distance shall be performed as frequently as necessary to provide adequate visib ility and will not be considered as part of a mowing cycle. COMPENSATION
806.06 Method of Measurement
The Department will not measure l itter/debris removal for payment but will consider it incidental to the Work unless otherwise specified in the Contract . The Department will pay for Mowing and Vegetation Removal by the mowing cycle. A mowing cycle includes the mowing of all areas within Project limits with overgrown vegetation one time. The Department will not m easure mowing for site distance but will consider it incidental to the Work.
806.07 Basis of Payment
The Department will pay for accepted quantities at the contract prices as follows: Item Pay Unit Mowing and Vegetation Removal Mowing Cycle All costs asso ciated with mowing and vegetation removal shall be included in the unit bid price for mowing. If the Contract does not contain a pay item for Mowing and Vegetation Removal, it will be incidental to other items of Work.
