DISCUSSION:
Added or revised line items:
Additive Change Order Number One was added to the contract for $47,232.50 per the
City resolution No. 2011-05 to use the remaining CDBG funds in both concrete and
drainage improvements project accounts. This change order included work such as
removing and replacing pedestrian ramps and cross gutters.
Line Item Change No. 3 was to increase the sidewalk removal and replacement amount to
make up for the contractor's shortage to reach the original contract amount. The shortage
was mainly due to the difference in contractor's bid price and Engineer's estimate. The
increase was 1456.75 square feet of sidewalk in the amount of $9,468.88.
Line Item Change No. 5 was to increase the driveway quantity as more driveways were
required to be removed and replaced during the construction_to_meet -ADA-requirements.
The change amount was $5,237.19.
Line Item Change No. 6 was to decrease the curb and gutter quantity. The decrease in the
amount of $4,760.00 was as the result of Engineer's determination in the necessity of
removal and replacement of curb and gutter at certain locations in the field.
