THIS CHANGE ORDER PROVIDES FOR:
During the demo of the existing sewer manhole, the existing 24" sewer main was found to be Spiral Bound
PVC pipe and in order to properly tie-in the new SDR35 PVC pipe, the City directed the contractor to place
a 4' wide concrete field collar over the rubber gaskets at each end of the pipe. The contractor agrees to do
the above mentioned work for the lump sum price of $2,811.81.
During construction it was determined that the approved butterfly check valves were collecting an abundance
of rags and affecting the overall performance of the sewer lift station. The City then directed the contractor
to replace the (3) butterfly check valves between the wet well and the valve vault with (3) flap check valves.
The contractor agrees to accept a lump sum of $3,370.31, which is the difference between the original and
new check valves.
During the installation of the new guide rails, it was discovered that the existing access hatch required
extensive modifications to allow the removal of the pumps during maintenance operations. The contractor
agrees to modify the access hatch as necessary, modify the (3) pump bases, and align the pump bases and
access hatch for the lump sum price of $3,807.34.
