(the Consultant) completed a Sewer System <br />Evaluation Survey (SSES) of the condition of the existing Ixora Park sewer <br />infrastructure and recommended improvements to rehabilitate or replace <br />components of the system. <br />In response to the recommendations, IRCU has opted to replace the entire Ixora <br />Park gravity sewer system. This amendment to Work Order 15 serves to adjust the <br />scope appropriately. <br />AMENDED SCOPE OF WORK <br />TASK 1 - PHASE 2 SSES <br />The Phase 2 SSES is complete, but additional funds are required for assessing the <br />feasibility of a vacuum sewer system and review of documents provided by AirVac. <br />The Consultant will provide a summary of findings and recommendations to IRCU <br />based on our assessment of the vacuum sewer system. <br />TASK 2 -PIPE LINING AND LATERAL REHABILITATION <br />Approximately 4,100 LF of gravity sewer pipe was recommended to be cleaned and <br />lined using cast -in-place pipe (CIPP) and nine (9) laterals on these pipes were <br />recommended for rehabilitation.
