Edwards Public Works Director/ Title Public Works Director City Engineer's Report Item Description: 2014 Sanitary Sewer Rehabilitation Project Change Order#1 List of Exhibits A- Change Order Request No.l 1. Purpose. The purpose of this request is to gain council approval for Change order#] which will provide improved Infiltration and Inflow(I&I) protection of especially vulnerable manholes. 2. Background. On June 9, 2014 Council approved the 2014 Sanitary Sewer Rehabilitation Plan with an estimated cost of$250,000. The 2014 Sanitary Sewer Rehabilitation Project consists of Cured In Place Pipe (CIPP) lining approximately 4,000 feet of sanitary sewer pipes, manhole reconstruction, and lid replacement. These sewer lines are located in low lying areas where the pipe is below the groundwater elevation. These lines have significant I&I issues and the City will further reduce the amount of clean water entering the system which is treated by MCES. On August 1 l, 2014 Council awarded the contract to Insituform Technologies in the amount of$230,921.50. 3. Issue. The high water and heavy rains of the summer pointed to additional vulnerabilities in select manholes. Several manholes need to be raised and three were identified as being located in soils with excessively high hydrogen sulfide levels. (See Exhibit A) The contractor is currently installing the Cured in Place Pipe (CIPP)portion of the contract and is scheduled to complete the manhole portions no later than June 2015. 4. Funding. The budgeted amount for this project was $250,000. The contract award amount was $230,921. The Change Order will add $12,268 to the contract. The total contract amount with the change order will be $243,189. This project is funded with existing funds in the Sanitary Sewer Enterprise Fund. The additional amount will be included in our MCES surcharge offset. 5. Recommendation. It is my recommendation that the City council approve the change. COUNCIL ACTION REQUESTED: Consider a motion to accept change order#1 for the 2014 Sanitary Sewer Rehabilitation.
