Reason/Purpose for this Change Order:
CHANGE ORDER No. 13
June 7, 2010
The original plans show the asphalt to be ground and overlayed adjacent to the pervious paving on the east side
of Cleveland between 23rd and Bay Marina Drive. Due to grade differences between the existing asphalt and
!the adjacent curb surrounding the pervious pavement, there will not be enough asphalt left after grinding it to
match the pervious paving. For proper grades and to construct a sufficiet asphalt section on the east side of
Cleveland along the pervious paving from Bay Marina Drive to 23rd Street, the street must be excavated and
reinstalled lower to provide for a new structural section at the proper grades.
The City of National City and Contractor agree to the following change to the original Contract:
The Contractor shall demolish, remove and dispose of the existing street section, excavate and dispose of soil
:and prepare subgrade necessary for the installation of a new 6" AC on 6" CMB street section on the east side of
Cleveland adjacent to the pervious paving for a width of fifteen feet (15'). The Change Order represents the
'change in the lump sum bid for Demolition and Excavation. The added demolition and excavation area is 3,590
;square feet at $3.91 per square foot (equivalent to the base bid lump sum price calculated to square foot) for a
total of $14,036.90. The 6" AC on 6" CMB street section line item will be extended by approximately 3,590
;square feet at $4.35/sq. ft. totaling $15,616.50, and the AC Overlay line item will be reduced by approximately
2400 square feet at $2.50/sq. ft. totaling $6,000.00 credit. This change in the contract is approximatelly

Reason/Purpose for this Change Order:
During the installation of the sewer main on 23rd, the force main sewer pump was turned on seven separate
'occasions. On each occasion the contractor established a temporary connection, waited for the pumping to
:stop and flow to subside, removed the temporary connection and continued with the sewer main installation.
:City sewer crews stated that they were required to turn on the main do to unexpected flows from docked ships.
Although, this represents unexpected additional costs it is a cost saving from having by-pass pumps set-up
;throughout the sewer main installation.
