Pipe, elbows, risers and trash racks will become the property of the Department upon completion of the project.
236.04 Method of Measurement . Silt basin will be measured per each. Once a silt
basin has been constructed, it shall be paid for at the unit price per each. Maintenance and removal of existing silt ba sin will be measured per each. Once an existing silt basin has been cleaned out, it sh all be paid for at the unit price per each. Additional clean outs or maintenance may need to be performed on that silt basin throughout the length of the project.
236.05 Basis of Payment . Silt basin will be paid for at the contract unit price per each,
which price shall be full compensation for construction, maintaining, removal unless noted otherwise, grassing and any other work required to make the basin function. Maintenance and removal of existing silt basin will be paid for at the contract unit price per each, which price shall be full compensati on for maintaining, removal, grassing and any other work required to complete the work. Payment will be made under: 236-A: Silt Basin, Type - per each 236-B: Maintenance and Removal of Existing Silt Basin * - per each * Type may be specified SECTION 237 - WATTLES
237.01 Description . This work consists of furnishing, constructing and maintaining
wattles for the retention of soil around inlets, swale areas, small ditches, sediment basins and other areas as necessary. Also, the work includes removing and disposing of the wattles and silt accumulations. Measurement and payment for wattles will be made only when a pay item is included in the bid schedule of the proposal. The quantity is estimated for bidding purposes only and will be dependent upon actual conditions that occur during construction of the project.
237.02 Materials . Wattles used around inlets shall have a diameter of twelve inches
(12”) and a length adequate to meet field conditions. Wattles used at other locations shall have a diameter of twenty inches (20”) and a length adequate to meet field conditions. The minimum diameter for the above wattle sizes shall be one inch (1”) less than the specified diameter. The stakes used in securing the wattles in place shall be placed appr oximately three feet (3’) apart throughout the length of the wattle. Stakes shall be wooden and of adequate size to stabilize the wattles to the satisfaction of the Engineer. Wattles shall be one from the Department’s APL.
