labor, tools, and equipment necessary and for excavation, including the removal
and disposal of the existing pipe material, if applicable, connections to new
sewer, concrete encasement; backfilling; crushed stone bedding; select material,
gravel sub-base, testing; and installation of the pipe, as indicated on the Drawings
or as directed by the Engineer.

pipes entering a manhole with greater than 2-feet of vertical drop shall require an

but only if the vertical drop is greater than 3-feet (unless otherwise directed by
Engineer at a negotiated cost).

tools, and equipment necessary and for excavation, including the removal and
disposal of the existing pipe material, if applicable, connections to new sewer,
concrete encasement; backfilling; crushed stone bedding; select material, gravel
sub-base, testing; and installation of the pipe, as indicated on the Drawings or as
directed by the Engineer.
Work shall conform to the City of Nashua Standard Specifications Sewers &
