PhaseI ATKINS <br />INDIAN RIVER COUNTY UTILITIES DEPARTMENT <br />WORK ORDER No. 4 <br />SCOPE OF SERVICES <br />W,est Regional TTP Structural Improvement s Phase I <br />Background <br />In March 2021, Indian River County Utilities Department (11I requested that Atkins, (Consultant) <br />provide technical services to design replacements foi the bridges that cross the oxidation ditches <br />at the West Regional Wastewater Ireatryient Plant (West WWTP),. To determine the scope of <br />services requO-ed, Atkins visited the West WWTP on March 8,, During that site visit, it 'was <br />determined that -there were significant concerns regarding the structural integrity of both the <br />anoxic ditches and associated bridges,, "This culminated in the recommendabon to have Staff <br />maintain 10to 15 feet distancefrorn the oxidation ditches. Due to structural concerns regarding <br />the oxidation ditches, it was determined that the Scope of Services would be broken into two <br />Phases as follows: <br />Phase 1: Evaluate the current structural integrity of the overall oxidaflon ditch structure and <br />associated Ibrid,ges. Perform vIsual condition assessment avid make a record of cliefects observed <br />during inspection, in ting location and size of defects documented. Perform survey of the <br />oxidation ditch under empty and full conditions to determine location and extent of any <br />movement occurring in the walls, bridge and associated piping. Analyze the tanks based on <br />avalHable knowledge. Determine exterst of repairs and/or replacements required. Provide <br />options for addressing the issues that are identified and assist the ou nt iin determirsh-ig the <br />preferred alternative. Provide a rough order of mAgnitude engineer's estimated cost for <br />structural repairs. These decisilons will be affected by the intended use and service IHfe expected <br />from the renovated system,. <br />11 1 11 111 11 <br />LMSE, �i =7 <br />Scope of'Siervices <br />This Scope of Services is for technical services associated with West WWTP Structural <br />lir,pro vements Phase 1. The sciope, consists of structural evaluations and verification <br />calculations that wfll result in generation of options for addressing the structural issues <br />associated with the oxidation ditch aind bridge. These options will include repair and upgrade <br />options. 'These options will be presented at a workshop with IIRC and a final decision on <br />upgrading of the structures will be determined. <br />Task 01 Project Management <br />a.
