Water valves have not been located in the field by the City. The Contactor shall

his representative, shall be considered the Contractor's responsibility.
When a water valve is in the sidewalk area being repaired, the Contractor shall
verify that the valve is at, or a maximum of inch below, the finished elevation of
the sidewalk.
If the elevation of the water valve does not meet the proper elevation, the City of
Waterloo shall be contacted as soon as possible. When the valve has to be
raised or lowered by adding or cutting off the pipe, the Contractor will oe paid the
bid price for that work under WATER VALVE REPAIR.
During the placement of concrete where water valves are present, concrete shall
be separated from the water valve in accordance with a method apprcved by the
Engineer. An acceptable method consists of the following:
Placement of ASTM 3034 plastic PVC pipe around the water valve cap before
concrete is placed. This pipe should be cut to the appropriate depth of sidewalk.
After placement and finishing of the concrete, the pipe section shall be removed
and the area under the cap filled with suitable fill material. A maximum space of
one-quarter inch (1/4") between the finished sidewalk and water valve cap will be
acceptable. This work will not be measured for payment, and therefore, will be
considered incidental to applicable bid items.
