PBOT recently updated the specific bid items and unit cost pricing for their Public Works Permit performance guarantee requirements. Values had not been updated for several years and needed to be made consistent with their small capital improvement projects, as the amounts were not adequate to support construction if PBOT needed to collect on the guarantee. The general methodology for calculating the guarantees has not changed otherwise and is based upon the scope of work of improvements triggered by a private development project.
