Meeting
REQUEST: Public Works Department Informing the City Commission on the status of the
newly constructed Winter Springs Boulevard pavement
PURPOSE: The purpose of this agenda item is to provide the City Commission information on
the status of the newly constructed Winter Springs Boulevard pavement.
CONSIDERATIONS:
· The pavement on Winter Springs Boulevard was recently reconstructed or milled and
resurfaced from Tuskawilla Road to Arrowhead Court. At the completion of construction,
the ride quality was poor in some locations due to pavement undulations.
· Acceptance testing indicated that there were 30 locations that had smoothness deficiencies in
accordance with the project specifications. A smoothness deficiency is defined as any
location on the final pavement surface that is more than 3/16" above or below level when
measured using a rolling straight edge.
· Possible reasons for the smoothness deficiencies include one or more of the following:
o Poor workmanship (speed of installation, skill and experience of the laborers, etc.)
o Substandard equipment
o Defective materials
o Uneven curb lines
· The contractor, OPC, recently performed corrective measures consisting of the heating and
cross-rolling of the pavement at deficient locations that were too high. This seems to have
smoothed out the high points. However, heating and cross-rolling does not correct low
points.
· At the City's request, OPC will be performing a second rolling straight edge test in the near
future. Deficiencies identified in this test can be handled in one of two ways per the project
specifications:

1. Correct the deficiency by removing and replacing the full-width of the pavement for a
minimum of 50-feet on each side ofthe deficiency.
2. If an engineering determination indicates that the deficiencies are sufficiently separated
so as not to significantly affect the ride quality of the pavement and corrective action
would unnecessarily mar the pavement appearance, a payment reduction can be issued.
The amount of payment reduction would be equal to the quantity of materials the
contractor would have removed and replaced had the corrective action been taken.
· Staff intends to review the results ofthe rolling straight edge test and, as a minimum, have
all smoothness deficiencies 1/4-inch or greater to be corrected by removal and replacement
of the full-width ofthe pavement for 50-feet on each side of the deficiency. Smoothness
deficiencies less than 1/4-inch but greater than the 3116-inch maximum allowable deficiency
will be evaluated on a case-by-case basis.
