CONNECTING PIPE OF DIFFERENT MATERIAL
(Mechanical joint couplings, Strongback Fernco or equal and Reducers)
Connecting sewer main pipe of different materials shall be done with either a
Strongback Fernco coupling (or equal) or a dresser style watertight mechanical
joint (MJ) coupling unless that pipe connection is from PVC to DI in which an MJ
coupling shall be used. When a pipe is to be CIPP lined (as shown on the plan
set), a regular rubber Fernco (or equal) type coupling shall be used with stainless
steel straps, which shall be incidental to the cost of the CIPP lining
The contractor shall carefully measure the outside diameter of each pipe to
determine the correct coupling prior to ordering.
A manufacturer's data sheet shall be submitted and approved by the Engineer
prior to construction.
Strongback Fernco (or equal), mechanical joint couplings and reducers shall
measure by each installation completed in place and paid by each installation for
Item 1j.
. Reducer connections will follow the same specifications of section C.1.
The work of connecting a new pipe to an existing brick sewer pipe at a location
where the existing sewer pipe has an existing connection hole will be paid by
Item 1i.
REPLACE OR CONSTRUCT SEWER MANHOLE:
The work of this item shall be paid per vertical foot measured from the lowest
pipe invert elevation to the rim elevation for new or replaced manholes including
a standard 30" frame and cover. Replacing an existing sewer manhole frame and
cover shall be measured by the each, including removing the existing frame and
cover, adjusting to finish grade and reconstructing up to 12 inches of the
supporting brickwork.
The contract unit price per each manhole to be paid shall constitute full
compensation for supplying all material, labor, tools, and equipment required to
remove and dispose of the existing manhole and install a new manhole as
specified in Section 02631, PRECAST MANHOLES & CATCH BASINS.
The unit price for this item shall include excavation, crushed stone bedding, and
