Description of work to be done, estimate of quantities and prices to be paid. Segregate between additional work
at contract price, agreed price and force account. Unless otherwise stated, rates for rental of equipment cover only
such time as equipment is actually used and no allowance will be made for idle time.
The anticipated amount of pipe replacement for each individual spot
repair was based on reviewing the TV video taken from inside the line
In some cases the amount of damaged pipe seen from inside the line does
not reflect the total damage as seen after the line is uncovered For
instance a hole in the pipe seen from the inside may be in reality just
part of a lengthy section of cracked pipe, the cracks not having yet pene-
trated to the inside of the pipe to become visible during the TV inspectic
Therefore the contractor must replace the entire damaged section Also
during some excavations unanticipated obstructions are present such as
other utilities or concrete The amount of extra work on each location
was negotiated to reflect the actual circumstances. See attached infor-
mation for a detailed description of each location and the extra work
required
Net Increase ® Decrease O in Contract $ -13,400.00
