The successful bidder will be required to furnish a performance bond and a separate payment
bond each in the amount of one hundred percent (100%) of the contract price.
Progress Payments: On not later than the last day of every month, the Contractor shall prepare
and submit an invoice covering the total quantities of work that have been completed from the
start of the job up to and including the last day of the preceding month together with such
supporting evidence as required by the CITY.
Retainage: The CITY shall retain a portion of the progress payments, each month, in accordance
with the following procedures:
1. Until work is 50% complete, as determined by the CITY, retainage shall be 10% of the
monthly payments claimed. The computed amount of retainage shall be deposited in a non-
interest-bearing account established by the CITY.
2. After the work is 50% complete, and provided the Contractor has satisfied the CITY in
quality and timeliness of the work, and provided further that there is no specific cause for
withholding additional retainage no further amount shall be withheld.
3. Upon substantial completion, the amount of retainage shall be reduced to 2% of the total
contract price plus an additional retainage based on the CITY's estimate of the fair value of
the punch list items and the cost of completing and/or correcting such items of work, with
specified amounts for each incomplete or defective item of work. As these items are
completed or corrected, they shall be paid out of the retainage until the entire project is
declared completed. The final 2% retainage shall be held, in the non-interest-bearing
account, during the two-year warranty period and released only after the CITY has accepted
the project.
Liquidated Damages: In the event that the Contractor fails to satisfactorily complete the work
contemplated and provided for under this contract, on or before the date of completion Friday,
November 13, 2026, the CITY shall deduct from the payments due the Contractor each month,
the sum of one thousand dollars ($1,000.00) plus engineering charges per day for each
calendar day of delay, which sum is agreed upon not as a penalty, but as fixed and liquidated
damages for each day of such delay, to be paid in full and subject to no deduction. If the
payments due the Contractor are less than the amount of such liquidated damages said damages
shall be deducted from any other monies due or to become due the Contractor or shall be paid by
the Contractor's surety.
The CITY reserves the right to reject any or all bids or any part thereof, to waive any formality,
informality, information and/or errors in the proposal, to accept the proposal considered to be in
the best interest of the CITY, or to purchase on the open market if it is considered in the best
interest of the CITY to do so.
