MIAMI (AP) - North Miami Beach city officials paid to build 254 manholes, but no one knows whether they were built. An audit shows duplicate purchase orders and no record of where the work was performed.

The Miami Herald also reported Tuesday that the city does not know whether more than four miles of water-and-sewer pipes or 142 shut off valves were installed, even though they were paid for. The construction is part of a $2.2 million project.

Jackson Land Development, the construction company in charge of the project, did not return calls seeking comment.

The city's public service director resigned in May after admitting he approved purchase orders for services and materials that were not performed or delivered.
