719 Construction methods shall conform to the applicable requirements of this Specification. Tests shall be performed as set forth in 675.11. This work shall also include construction and maintenance of temporary lines, as requir ed, to avoid disrupting operation of the existing sanitary sewer system. Temporary service may be maintained by use of pumps and hose lines or in any other manner satisfactory to the Engineer.
675.13 Manhole :
Constr uction of manholes shall conform to the applicable requirements of 605.
675.14 Abandoning Manholes :
Upon completion of the new gravity sewer and placing it in service, or upon abandonment of an existing sewer line, the existing manholes to be abandoned shall be cut down to two ( 2) feet below the proposed finished grade, the inlet and outlet ends of existing pipe plugged with CLSM, Type C, and the manhole backfilled to subg rade elevation with material from the unclassified excavation and compacted.
675.15 Adjusting Manholes :
Construction methods shall conform to the applicable requirements of Section 605.
675.16 Capping Ma Nholes :
The existing manhole shall be removed to a minimum depth of 1.5 f eet below the subgrade elevation. Permanent forms of sheet or corrugated sheet steel shall be used to form over the manhole opening. Side forms may be undisturbed earth. No form work shall be placed inside the manhole which will interfere with the flow of the existing sewer. Steel shall be set and the cap poured to Plan dimensions. No finish is required.
675.17 Junction Boxes :
Construction methods for junction boxes shall conform to the applicable requirements of Section 605.
675.18 Method of Measurement :
675.18 1-Sanitary Sew er Pipe: Pipe of the different types and sizes, both new and
reconstructed, will be measured by the linear foot in place. Measurement will be made along the centerline of each pipe installed. Branch connections, valves, tees, wyes, and elbows will be measu red along their centerlines and these lengths included in the total lengths of the appropriate conduit. Wyes, tees, and other branch connections will be measured along the centerlines to points of intersection. Pipe with sloped or skewed ends will be measu red along the longitudinal axis through the center of the pipe. The portion of pipe extending through to the inside face of manholes, boxes, or other structures will be included in the measurement.
675.18.2 Manholes: Manholes will be measured as a compl ete unit in place, including
frame, cover and cover castings.
675.18.3 Abandoning Manholes, Adjusting Manholes and Capping Manholes:
"Abandoning Manhole", "Adjusting Manhole", and "Capping Manhole" will be measured as a complete unit in place. 720 675.18.4 -Junction Boxes: "Junction Box" will be measured as a complete unit in place, including, if called for, manhole frame and cover casting (ring type).
675.18.5 Steel Casing Pipe: Steel casing pipe will be measured by the linear foot complete
in place.
675.19 Basis of Payment :
The quantities, determined as provided above, will be paid for at the contract unit price bid for the items listed below, which prices and payments shall be full compensation for excavation and bedding, except as otherwise provided. Backfilling, testing, construction and maintenance of temporary service when required, repair and repaving of areas not otherwise provided for in the contract, removal of surplus material and clean -up, furnishing all materials and doing all the work prescribed in a workmanlike and acceptable manner, including all labor, tools, equipment, supplies, and incidentals necessary to complet e work. When boring and jacking of casing pipe is specified in the Contract, the cost of the boring and jacking operations will not be paid for separately but shall be included in the unit price bid for the respective casing pipe pay items. If the Enginee r determines that field conditions necessitate the boring and jacking of casing pipe not so specified, the casing pipe pay item as originally specified will be non -performed and the cost for such boring and jacking operations, including the cost of casing pipe, will be paid for in accordance with 109.4
