The Borough Engineer may direct test holes to
be excavated in advance of setting stakes to determine the location
of existing public utilities. The contractor shall be paid for such
excavation at the unit price bid for extra excavation.
The line or grade may be changed by the Borough
Engineer without additional compensation over the price bid, unless
extra excavation is caused thereby over that indicated on the plans,
or unless such change makes it necessary to replace more pavement
than would have been required on the original line. In such cases
the extra work shall be paid for as follows:
A. Extra excavation shall be paid for at the unit price
bid.
B. The replacing of extra pavement shall be paid for
at the unit price bid, or, if no unit price has been bid, payment
shall be made under a supplementary agreement.
The contractor shall furnish a sufficient pumping
plant, and he shall provide and maintain drainage in the trench satisfactory
to the Borough Engineer. All water from the sewer trench and from
any sewer, drain, or watercourse which may be interfered with shall
be conveyed to a suitable point of discharge in a manner satisfactory
to the Borough Engineer.
When, for any reason, the work is left unfinished,
all trenches and excavations shall be filled up and the roadways and
sidewalks left unobstructed, with their surfaces in a safe and satisfactory
condition.
The method of breaking out any concrete to be
removed must be approved the Borough Engineer. The dropping of a heavy
ball or weight for such purpose will not be permitted.
