1. BACKGROUND
This ordinance authorizes the Director of Public Utilities to enter into a construction contract via the City’s Invitation For Bid process with Ironsite, Inc. for the Livingston Noe Bixby Culvert Removal project, CIP #611724-100000, in an amount up to $359,139.98 and to encumber funds with the Department of Public Service for prevailing wage services in an amount up to $2,000.00, for a total expenditure of $361,139.98.
