Nawrocki and Members of City Council CC: Sam Azad, City Manager VIA: Gina Dutcher, City Clerk From: Gene Michael, Wastewater Director SUBJECT: A RESOLUTION AWARDING A CONSTRUCTION CONTRACT IN THE AMOUNT OF $13,794.20 TO PARKER EXCAVATING INC., FOR EMERGENCY SANITARY SEWER POINT REPAIR IN THE INTERSECTION OF PRAIRIE AVENUE AND LEE LANE AND AUTHORIZING THE PURCHASING AGENT TO EXECUTE THE SAME SUMMARY: Attached is a resolution awarding a construction contract to Parker Excavating Inc., for emergency sanitary sewer point repair at the intersection of Prairie Avenue and Lee Lane. PREVIOUS COUNCIL ACTION : None BACKGROUND : On August 25, 2014, the Wastewater Department discovered that the 60-inch diameter manhole in the intersection of Prairie Avenue and Lee Lane was approximately five feet below grade. The manhole needed to be surveyed for a future project in which the 38- inch reinforced concrete line will be lined with a cured-in-place liner. This process requires access to the manhole. The 38-inch reinforced concrete sanitary sewer main is deteriorating and by lining it, we essentially create a new pipeline without void, cracks or surface spalling. In addition, a 48-inch manhole feeding into the 38-inch line was found adjacent to the 60-inch diameter manhole whose base was deteriorated to the point that raw sewage would soon be leaving the manhole and entering the groundwater. Therefore, it was determined that both sanitary sewer manholes needed to be replaced. Parker Excavating Inc. was asked to raise the 60-inch diameter manhole to street grade in order to ensure the timely advertisement and bid of the future lining project, and to replace the 48-inch diameter manhole to ensure public health and safety. The quote for the unit prices for the work by Parker Excavating Inc. and the change order for the project are attached. This work was performed under the Sanitary Sewer Point Repair multi-year contract under which nine (9) contractors were qualified via competitive bid. During the project the costs were modified by actual field quantities as noted on the attached change order. The cost breakdown for the project is as follows: Sanitary Sewer Replacement-related Remove & Replace 8" PVC < 12' $1,016.00 Remove & Replace 48" Dia. Manhole $2,950.00 Remove & Replace 60-inch Dia. Manhole $3,500.00 Traffic Control $1,000.00 Mobilization $800.00 67% Subtotal: $9,266.00 Surface Improvement-related Asphalt Patch – 4-inch on 6-inch Class 6 ABC, 21-100 SF $2,552.00 Flowfill $1,976.20 33% Subtotal: $4,528.20 TOTAL: $13,794.20 FINANCIAL IMPLICATIONS : Funding for this project will come from the sanitary sewer rehabilitation budget funded by the Sewer User Fund. Funding was available and had been budgeted, appropriated and allocated to Project No. 13-012 (WWAN03). BOARD/COMMISSION RECOMMENDATION : Not applicable STAKEHOLDER PROCESS : None ALTERNATIVES : Alternative No. 1 – No Action Under this alternative, the City would make no improvements to the existing sanitary system and the lining project on the attached 38-inch reinforced concrete pipe would not be performed. This would cause further decay of the 38-inch reinforced concrete pipe and eventually lead to failure of the sanitary sewer main, allowing raw sewage to exit the main and enter the ground water in close proximity to the Arkansas River. Alternative No. 2 – Put Manhole on the Rehabilitation List Under this alternative, the City would make no immediate improvements to the existing sanitary system. The manholes would be put on a rehabilitation list and prioritized by the level of importance for future rehabilitation projects. Again, there would be a risk that further decay of the 38-inch reinforced concrete pipe would occur and eventually lead to raw sewage exiting the main and entering the ground water in close proximity to the Arkansas River.
