Iowa Admin. Code r. 591-13.4 - Contracts, change orders and final costs
(1) Contracts shall be negotiated and
finalized by the administrator after award by the board but prior to the
signing of a contract, based on the most accurate scope of work covering
eligible community remediation or packaged community remediation
owner/operators.
(2) Change orders
may be negotiated for:
a. Extraordinary costs,
including:
(1) Extensive rock drilling if not
originally included in the request for proposal.
(2) Unexpected vapor analysis in caverns,
caves and sinkholes.
(3) Confined
space personal protection gear if required.
(4) Additional drilling if the depth to the
aquifer greatly exceeded the estimates in the request for proposals.
(5) The completion of boreholes to monitoring
wells when groundwater contamination is found during the project.
(6) Additional borings or monitoring wells to
define transition zones as requested by the DNR .
(7) Any other situations where approved by
the administrator or the board when authorized to do so.
b. A change in scope of work when:
(1) Additional sites are found to be eligible
for the project.
(2) A site is
found not to be eligible for benefits, except the board may include a site
which was eligible at the start of the project but lost eligibility after the
contract was initiated.
(3) A site
which had previously tested clean or was underwritten as provided in Iowa Code
section 45 5 G. 11 is determined to have contamination and the DNR requires
completion of a site cleanup report.
(4) Free product or abandoned tanks are
discovered during the course of completion of areawide site cleanup
report.
(5) A site requires
additional testing to ascertain the type of contamination present.
(6) A site requires testing different from
the DNR normal testing requirements.
(7) Other situations are approved by the
administrator or the board when authorized to do so.
(3)The request for
proposals defines the scope of work for borings, completed wells, testing, and
areas similar to these. Costs provided by those bidding on the overall scope of
work are on a per unit basis and subject to renegotiation if there has been a
significant change in scope.
(4)
When the amount of time and costs for services are determined by the bidder in
order to meet the requirements included in the request for proposal, the costs
will be paid on a cost-not-to-exceed basis, as outlined in the bidder's
proposal.
(5) The administrator may
approve any single change order not to exceed 15 percent of the negotiated
cost, without prior board approval, as outlined in rule 13.8(455G). If the
cumulative total of all change orders on a given project exceeds 25 percent of
the total initial negotiated cost, board approval is required on all subsequent
change orders for the project. Board approval is not required when an increase
occurs as a result of the addition of an eligible site. Neither is board
approval required when an owner/operator elects to join a community remediation
or packaged community remediation project after the contract is
awarded.
