Specifications include, but are not limited to: The work specified in this contract consists of the replacement and/or conversion of Florida type catch basin tops to Types 16, 17 or 18, in various locations in Richland County and Chapin area of Lexington County. This work shall consist of all materials, labor, equipment, tools, and incidentals necessary to perform the work specified in this contract. It shall also include the proper clean up and disposal of all debris associated with the removal of the damaged catch basin and other materials. The contractor is expected to furnish their own traffic control that must conform to Part V of the South Carolina Manual on Uniform Traffic Control Devices for Streets and Highways (as described below under Work Zone Traffic Control.) Each top shall require a minimum of 10 linear feet of sidewalk and curb and gutter on each side of the new catch basin retrofit to be removed and replaced with the catch basin, if existing. Exceptions can be made for catch basin tops adjacent to ADA ramps and or structures as approved by an SCDOT RME or his/her Representative. All concrete shall conform to the requirements as specified. The removal of the existing top, sidewalk, curb and gutter, and throat shall be performed so as not to damage the existing catch basin brickwork, adjacent pavement edge, adjacent concrete or adjacent structures or property. If pavement must be removed to accommodate the new structure, it will be saw cut to provide an acceptable pavement edge. The amount of removal will be deemed as the amount necessary to successfully convert the catch basin and provide the proper drainage. The new catch basin top and throat shall be formed, graded, placed and finished in accordance with the attached Standard Drawings. All concrete associated with the conversion is to be Class 3000 concrete mix from an SCDOT certified concrete plant. Concrete shall be thoroughly consolidated against the faces of all forms and joints, including concrete previously constructed.
