Text of Legislative File CM -2018-1716
Consider executing Quantity Adjustment/Change Order No. 1 with National Power
Rodding Corporation for the Parkfield Circle Culvert Rehabilitation Project.
The Parkfield Circle Culvert Rehabilitation project provides for rehabilitation at Parkfield
Circle and preventive measures at Hampton Lane to extend the useful life of the
deteriorated corrugated metal pipe culverts that were constructed in the mid -1980's under
these streets in the Windy Park residential neighborhood.
Change Order/Quantity Adjustment No. 1 will add preventive maintenance for culverts
under Breezy Court and for the upstream end of culverts under Gattis School Road to the
Contract. Previous projects, this project, and these additions will complete necessary
rehabilitation and preventive maintenance work for the entire length of concrete -lined
channel traversing through Windy Park from Dell Computer property at the south end of the
neighborhood up to Gattis School Road at the north end.
Change Order/Quantity Adjustment No. 1 also adjusts quantities or deletes items that are
currently known. Concrete curb and gutter and sidewalk anticipated to be removed and
replaced, and an anticipated curb inlet repair, at Parkfield Circle were performed as part
of a concurrent street maintenance project and are to be deleted from this project. The
City o1 Roernd Rock Page 1 Printed on S/f 0/204e
Agenda Item Summary Continued CM -2018-1710
lining thickness for the Parkfield Circle culverts may be reduced and therefore a deletion is
included to account for this reduced thickness. Finally, the quantities of concrete riprap at
Parkfield Circle, and grout needed for void filling at Hampton Lane require increased
adjustment due to actual field conditions that were unknown prior to construction.
Change Order/Quantity Adjustment No. 1 will increase the Contract by $30,656.70 for an
adjusted total of $223,232.10. Of the increase, $18,187.50 is due to the aforementioned
quantities adjustments, and $12,469.20 is due to the aforementioned additions and
deletions through change order.
Staff recommends execution of Change Order/Quantity Adjustment No. 1.
