SOURCE OF FUNDS:
Funds are available in the following account(s): 134-4497-50216
REASONS FOR CHANGE:
The original plan cross section for the overlay section from station 49+00 to 113+00 would have put the crown
of the roadway in the fast lane of the northbound traffic. Discussions were had with the City and the Contractor
to determine a potential solution to change the cross section to allow the crown of the roadway to be located at
the centerline of the road. After discussing all of the options, it was determined that the final overlay would be
placed thicker than the plan section to allow for an adjustment in the crown location. This was accomplished
by holding the 2" lift at the inside lane line and carrying a 1% cross fall to the centerline of the roadway. This
resulted in a varying depth overlay from 2"to 4" of HMA Type B. Additionally; there were wheel ruts that varied
in depth in the existing asphalt that added to the depth of the overlay. These ruts were typically 1" deep. This
accounts for the contract overage for Item 18, HMA Type B.
This Change Order requires Council approval. The total contingency approved for this project was 10% of the
original bid price. This change order increases the overage to 13.7% of the original bid price.
