533.05 Basis of Payment.
a.General. The accepted length of a storm sewer pipe, measured as specified above, will be paid for at the respective contract unit price for the sizes and types of pipe provided in the proposal, complete in place, which shall be payment in full for all materials, equipment, labor, and incidentals necessary to complete the work, except that ex cavation and backfill will be paid for as provided in Section 214.

534.01 Description.
This Section shall cover the work of cleaning existing drainage structures including all types of pipes, reinforced box culverts, underdrain outlets and other drainage structures shown on the plans.
534.02 Material s.
There will be no material requirements other than the hardware cloth for the rodent screens on underdrain outlets shown on the plans.
534.03 Construction Requirements.
Pipes, box culverts, catch basins, manholes, drop inlets, pipe underdrain outlets and other drainage structures shown on the plans shall be cleaned of all dirt, leaves, limbs, roots, grass, sludge, grease, trash and other debris. Obstructions within a 5 foot distance outside of the inlet and outlet ends of the drainage structures shall also be removed as a part of cleaning the structures. All materials removed during cleaning shall be disposed off of the right -of-way in accordance with the requirements for disposal given in Section 206. The Contractor shall implement the "Best Management Practices" (BMP's) noted in Section 107 for the control of sediment that will be removed during the cleaning. The Contractor shall perform the work so that there is always adequate drainage of the roadway at all times. The Contractor shall repair all damage to drainage structures that result from cleaning methods and procedures that are used without consideration for the protection of the drainage system. The Engineer will not allow the use of any cleaning method or equi pment that may result in damage to the structure or damage to the areas adjacent to the structure. Rodent screens shall be fabricated and installed as shown on the plans or as directed by the Engineer.
534.04 Method of Measurement.
The cleaning of existi ng pipes, box culverts, catch basins, manholes, drop inlets, pipe underdrain outlets and other drainage structures will be measured per each drainage structure or per foot along the length of the drainage structure. Measurement will be made only once for each item cleaned unless severe conditions result in the need for repeated cleaning and the repeated cleaning is not caused by the activities of the Contractor. All recleaning due to the activities of the Contractor shall be done at no additional cost to th e Department. Pipes, culverts and other drainage structures measured for cleaning along the length of the structure will be classified for payment based on the horizontal opening of the drainage structure. The diameter of round pipe and the span of "span a nd rise" pipe will be shown as a horizontal opening classification for payment. Each pipe will be measured separately for payment regardless of the number of pipes adjacent to each other at one location.
534.05 Basis of Payment.
The horizontal opening of a culvert will also be sho wn as a classification for payment. The horizontal opening of a culvert shall be the horizontal opening in a single barrel culvert or the sum of the horizontal openings in a multiple barrel culvert. Two classifications of horizontal opening will be given f or the purpose of measurement for payment. The first classification of horizontal opening shall be structures with an opening less than or equal to 48 inches. The second classification of horizontal opening shall be structures with an opening greater than 48 inches. If separate pay items are not shown on the plans for cleaning catch basins, manholes, and other appurtenances to the structures measured by linear feet (pipes and culverts), the cleaning of these appurtanancies will be measured for payment by i ncluding the length through the appurtenances in the total number of linear feet of the attached drainage structure. The length through an appurtenance will be added to the length of the largest structure connected to the appurtenance.
534.05 Basis of Pay ment.
a.Unit Price Coverage . The contract unit price for cleaning existing drainage structures shall be full compensation for all materials, tools and labor required for cleaning the structures, disposing of all materials that are removed from the struct ure and installing new rodent screens.
b.Payment will be made under Item No .: 534-A Cleaning Pipe Underdrain Outlets - per each 534-B Cleaning Existing Catch Basin - per each 534-C Cleaning Existing Manhole - per each 534-D Cleaning Existing Drop Inlet - per each 534-E Cleaning Existing * (Less Than Or Equal To 48" Horizontal Opening) - per linear foot 534-F Cleaning Existing * (Greater Than 48" Horizontal Opening) - per linear foot * Pipe, Culvert, etc. SECTION 535 SIDE DRAIN PIPE
535.01 Description.
This Section shall cover the work of furnishing and installing side drain pipe in conformity with these specifications. The word "pipe" in this Section shall include both round and arch pipe. It shall cover only those pipes specifically designated on the plans as side drain; it shall not apply to other pipes laid parallel to the roadway. The kind, type, and size of each side drain pipe will be shown on the plans or in the proposal. The location of each will be shown on the plans or designated. This Section shall include furnishing and constructing such joints and necessary cutting to provide connections to other drainage facilities, and other incidentals necessary for completion of t he work.
535.02 Materials.
a.General Materials furnished for use shall conform to the appropriate requirements of Division 800, Materials, with specific reference made to Sections 831, 846 and 851.
