Plymouth Court Sanitary Sewer Extension ProjectTHE CITY OF Dubuque Au-Am~icaCi111 DUB E 1 Masterpiece on the Mississippi 2007 TO: The Honorable Mayor and City Council Members FROM: Michael C. Van Milligen, City Manager SUBJECT: Plymouth Court Sanitary Sewer Extension Project DATE: October 14, 2008 City Engineer Gus Psihoyos is recommending acceptance of the Plymouth Court Sanitary Sewer Extension Project, as completed by Drew Cook & Sons Excavating Co., Inc., in the final contract amount of $69,792.34, which is a 55% increase from the original contract in the amount of $44,892.34. The cost increase was due to an expansion of the work to be performed above and beyond the sanitary sewer work. While the street appeared to be in fair condition, the construction activity associated with the sanitary sewer project (use of heavy equipment, loaded dump trucks, etc.) accelerated its breakdown. The Engineering Department determined that additional repairs to the existing pavement, as well as the curb and gutter were needed. I concur with the recommendation and respectfully request Mayor and City Council approval. l/ Michael C.

Van Milligen, City Mana FROM: Gus Psihoyos, City Engineer SUBJECT: Plymouth Court Sanitary Sewer Extension Project (CIP 7101798) DATE: October 14, 2008 INTRODUCTION The enclosed resolution provides for the acceptance of the construction contract for the Plymouth Court Sanitary Sewer Extension Project. BACKGROUND The Plymouth Court Sanitary Sewer Extension Project involved the replacement of approximately 525 feet of 6-inch clay pipe with 8-inch PVC from the intersection of Logan and Victoria Streets north 250 feet and then west on Plymouth Court 280 feet. The original 6-inch sanitary clay pipe had many offset and broken joints that proved to be a maintenance problem. The project was awarded based on a competitive quotation process for public improvements in accordance with Iowa Code, Section 26.14. DISCUSSION The Plymouth Court Sanitary Sewer Extension Project was completed by Drew Cook & Sons Excavating Co., Inc., in the final contract amount of $69,792.34, which is a 55% increase from the original contract in the amount of $44,892.34. The cost increase was due to an expansion of the work to be performed above and beyond the sanitary sewer work. While the street appeared to be in fair condition, the construction activity associated with the sanitary sewer project (use of heavy equipment, loaded dump trucks, etc.) accelerated its breakdown. Engineering determined that additional repairs to the existing pavement as well as the curb and gutter were needed. This resulted in an increased quantity of graded stone base, pavement replacement, and 6-inch PCC and additional 3-inch breaker run, 6-inch drain tile, and a catch basin. Only 8 percent (8%) of the overage was related to the sanitary sewer work. RECOMMENDATION I recommend that the City Council accept the improvements and authorize the payment of the contract amount of $69,792.34 to Drew Cook & Sons Excavating Co., Inc., for the Plymouth Court Sanitary Sewer Extension Project. BUDGET IMPACT The project funding summary is as follows: CIP No. Fund Description Fund Amount 7101798 Plymouth Court Sanitary Sewer $47,000.00 7201066 General Storm Sewer Repairs 4,383.50 3001972 Savings from Cleveland Ave Street Reconstruction 27,007.25 Total Project Funding $Z$~~.7.
