AGENDA ITEM: Change Order No. 1
Aerated Sludge Holding Tank at Wastewater Treatment Plant No. 2
Bid No. 0102-22 Re-Bid
SUBMITTED BY: Donna Kaluzniak, CEP, Utility Director
DATE: April 18, 2003
BACKGROUND: The contract for the Aerated Sludge Holding Tank at Wastewater
Treatment Plant No. 2 was awarded to Gruhn May, Inc., and the Notice to Proceed date was
scheduled for January 6, 2003. After contract award, it was determined that a building permit
would be required from the City of Jacksonville (COJ). Per a telephone conversation between the
COJ and our engineer, Gannett Fleming, this would only require a "two-set" permit, consisting a
very limited review that could be accomplished quickly.
Unfortunately, upon application, COJ determined that a "ten-set" permit would be needed,
requiring review by multiple departments. The ensuing permit process lasted over three months,
and resulted in requirements for approximately 870 cubic yards of additional excavation to create
on-site ponds for flood attenuation, as well as changes to some of the drainage design.
The contractor has provided a cost for the additional work, in the amount of $22,718. Although
the contractor's bid unit price for excavation was $18 per cubic yard, Gruhn May is only charging
$14 per cubic yard in the change order. In addition, the contractor has been more than generous
by not assessing any charges for contract delays, which could have added a substantial amount of
money.
BUDGET: The contract was awarded in the amount of $512,050, and no contingency was
included in the award. However, sufficient monies are available in the sewer accounts due to
other items that were purchased under budget (computer equipment; software and radios), and
unused funds in professional services.
RECOMMENDATION: Authorize a change order to the contract with Gruhn May, Inc. in the
amount of $22,718 for Bid No. 0102-22 to meet flood attenuation and drainage requirements of
the City of Jacksonville Building Permit.
