DISCUSSION:
Added or revised line items:
Additive Change Order Number One was added to the contract for $1,010.00 per the
City's request for the installation of 1000 square feet of re -enforcement fabric on the base
of the cross gutter on Plaza Boulevard and Olive Avenue. Out of this 1000 square feet
only 500 square feet was required and it was installed by the contractor for the amount of
$505.00.
Additive Change Order Number Two (CO2) was added to the contract for $5,370.00 per
the City's request to delete the cross gutter located at 8th Street and D Avenue including
all the related items from the scope of work as described in the next paragraph. CO2 also
added the Bid Additive No.1 and Bid Additive No.2 to the scope of work. However city
decided not to perform any of the work included in the CO2 therefore CO2 was declared
void by the City. However, the Contractor performed a portion of this Change Order
before the City's decision was finalized. The amount of work performed was $3,326.00.
The City deleted the cross gutter located at 8th Street and D Avenue including all its
related line items as follows:

FINAL CONTRACT BALANCE
Line Item No. 3 was decreased from 10 pedestrian ramps to 8 pedestrian ramps resulting
in a change of $3,700.00.
Line Item No. 9 was decreased from 5075 Square Feet to 3107.5 Square Feet resulting in
a change of $17,707.50.
Line Item No. 12 was not performed by the contractor resulting in a decrease of $785.00.
Line Item No. 14 was not performed by the contractor resulting in a decrease of
$1,545.00.
Additive Change Order Number Three was added to the contract for $1,207.50 per the
City's request to remove a wider section of asphalt and replace with AC pavements in
order to make a smoother transition between the cross gutter and the street surface at 21st
Street and F Avenue.
Line item No. 5 was increased by 2 linear feet in the amount of $43.00.
Line Item No. 6 was increased because the amount required to replace sub -grade with
wet base was 97.62 Tons. This change added 72.62 Tons of base for a total amount of
$3,340.52.
Line item No. 7 was decreased by 10 square feet because the actual work was less than
the measured quantities resulting in a change of $81.00.
Line item No. 8 was increased by 25 square feet because at 20th Street and Wilson
Avenue the asphalt patching needed to be wider in order to have a smoother transition
between the asphalt and the cross gutter. The nature and price of work at this location
was the same as Line Item No. 8. The amount of increase was $87.50.
Therefore, the construction bid price of $90,993.60 was decreased by $15,308.98. Due to
said actual construction change orders and the net balance of line item changes resulting
in a final construction cost of $75,684.62.
CONTRACT ADJUSTMENT:
As a result of the above change orders, the contract price is adjusted as follows:
1. The final contract price to date is adjusted to $75,684.62.
2. As a result of the satisfactory completion of said project, a retention amount of
$7,568.46. is set for invoice processing and payment upon the receipt of required
signatures and City Council's ratification of this agreement and the Notice of
