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.

675.18 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.
