Okaloosa County BOCC — March 4, 2014 — Action Item Printout

BOARD OF COUNTY COMMISSIONERS AGENDA REQUEST DATE: March 4, 2014 TO: Honorable Chairman and Members of the Board FROM: Jeff Littrell SUBJECT: Insituform Technologies Change Order #1 DEPARTMENT: Water and Sewer BCC DISTRICT: All STATEMENT OF ISSUE: Approve Change Order #1 to add additional scope of work for the rehabilitation of gravity sewer (Phase II of maintenance contract). BACKGROUND: An annual maintenance contract with a two year initial contract period for the rehabilitation of gravity sanitary sewer was awarded on April 17, 2012. The initial phase was completed in 2012-2013 and consisted of relining over 7,000 feet of main trunk line sewer and 11 point repairs on Okaloosa Island (predominantly, the remaining main sewer line that runs the length of Santa Rosa Blvd). The lines that were repaired are the original sewer lines installed by the former Okaloosa Island Authority in the 1960s and are constructed of terra cotta pipe in 4’ sections. Most of the joints in these sewer lines were found to be leaking groundwater into the sewer system during an inspection program several years ago. The repair of the lines has cut down on the amount of groundwater being unnecessarily treated at the Arbennie Pritchett Water Reclamation Facility (conserving capacity) and will prevent future potential subsidence of the ground surrounding the leaking lines. OCWS staff is satisfied with the quality of work performed on the original phase and is ready to add to the contract, to facilitate the rehab of more gravity sewer. The next phase (Change Order #1) will consist of pre-rehabilitation cleaning and CCTV inspection of an additional 45,000+ LF of gravity sewer previously identified as problematic, primarily on the Island and in the Ocean City/Wright areas. In addition, two heavily corroded cast iron pipe lines (one under Eglin Parkway in Shalimar) will be cleaned with specialty equipment, then relined in this phase. The original contract was awarded to Insituform Technologies LLC in the amount of $288,383. This change order will add $193,820.00 to the original contract, for a revised contract total of $482,203. The Change Order Form and project breakdown spreadsheet are attached for your review. No change in contract time is needed for this change order. Although this is called a "change order", no changes are being made to the contract terms and conditions, time, or unit prices; this change order simply adds scope/quantities, as was originally intended to be Phase II. OPTIONS: Approve or deny. RECOMMENDATION: OCWS requests BCC approval to authorize the Chairman to execute Change Order #1 to Contract # C12-1955-WS with Insituform Technologies LLC, adding $193,820.00 in scope of work for the rehabilitation of gravity sewer (Phase II of maintenance contract). RECOMMENDED BY: APPROVED BY: Ernie Padgett, County Administrator
