In most instances, the Port’s internal controls over the review process for Pay Applications
worked well to assure billings pertaining to unit price work items were accurate and supported.
However, our audit identified instances in which Pay Applications were missing supporting
documentation or billed incorrectly, resulting in a potential overbilling of $124,771.
The contract defines “Unit Price Work” as work for which a unit price is established in the Contract’s
Schedule of Prices or by Change Order. The contract defines “Bid Quantity” as the total unit quantity
listed in the Schedule of Prices for an item of Unit Price Work. The Schedule of Prices for this contract
displayed a total of 41 unit price work items, with an estimated cost of $38,551,390. The total amount
incurred (as of December of 2022) is $43,940,232, an overage of $5,388,842. The contract allows the
bid quantity to exceed the estimated bid quantity by one hundred twenty five percent (125%), without
any contractual changes. When exceeding 125%, Section G-05.04.B.2. of the contract states, in part:
If the quantity of an item of Unit Price Work actually performed or to be performed is more than one hundred
twenty five percent (125%) of the bid quantity for that item, the Contractor or the Port may request a Change
Order revising the unit price for that portion of the Work that exceeds 125% of the bid quantity. (See
Appendix B for contract Section G.05.04.B.2)
There were 12 unit price work items whose quantity exceeded 125% of the original bid estimate. We
selected the eight unit price items that exceeded the 125% threshold by at least 1,000 units for our
sample testing, which covered 97.3% of the total items that exceeded 125%. The eight items had a
contract value of $7,394,040, however, as of December of 2022, the Port had paid $22,747,174, since
the quantities exceeded 125% of the bid quantity. Our testing focused on reviewing supporting
documentation for the quantities that exceeded 125% of the bid threshold. Our testing determined there
is a review process in place to assure Pay Applications are supported. Documentation was readily
available for the audit and there were receipts supporting the Pay Applications. We observed written
notes on the Pay Applications and corrections that were made by the reviewer, prior to making
payments. We did, however, find instances in which supporting documentation could not be located, as
listed in Table 2. The five instances total $124,771, which is 0.9% of the sample tested. The Construction
Management (CM) team took immediate action and contacted the contractor to obtain supporting
documentation. Table 2 details the outstanding requests as of the date of this report.
