2.22R Non-Priced Items (NPI) Non-Priced Items (NPI) are defined as those which have not been included as a specific unit price items in this bid document. An allowance for NPI’s has been included in the Bid Proposal, which represents the maximum amount that may be expended for such work during the term of this contract.

NPI work shall be identified by the CONTRACTOR in its proposal at the time a Work Order is being prepared. Once an NPI is approved in a Work Order, it may be incorporated into the contract and thus permit its continued use as a unit priced item for future Work Orders. The NPI work shall be priced as follows:

1. Florida Department of Transportation (FDOT) Construction Cost History cost data books (latest Edition) shall be used for the NPI.

2. If the NPI is not provided in the above-referenced FDOT publication, the price shall be negotiated with the CONTRACTOR utilizing other referenced sources as identified by the COUNTY. An example of such sources would be previous Hillsborough COUNTY bids, bids from other municipalities, etc.

For an individual work order, the value of NPI work shall not exceed 10% of the total work order value without prior approval of the Department Director. Once an NPI is approved in a Work Order, it may be incorporated into the contract and thus permit its continued use as a unit priced item for future Work Order.
