CIP Sheet. lt EN HILLS MEMORANDUM DATE: January 28, 2013 TO: Honorable Mayor and City Councilmembers Patrick Klaers, City Administrator FROM: Terry Maurer, Public Works Director SUBJECT: Proposals for Engineering Services South Water Tower Rehabilitation BacklZround In 2012 both of the City's water towers were fully inspected. The recommendations coming from these inspections were that the South Water Tower should be completely rehabilitated inside and out within the next two years. There were also several minor structural items that were noted that need to be addressed. This project was programmed in the 2013 CIP at an estimated cost of$900,000 (attached is the CIP sheet). This type of project needs specialized engineering and inspection services so staff requested proposals from three engineering firms of Bolton and Menk (BMI), SEH, and WSB. All three responded to the request with proposals that reflected an understanding of the project and a team capable of completing the work. After carefully reviewing the fees proposed by each firm to ensure there was an "apples to apples" comparison, the following table reflects the proposed fees from each firm. FIRM TASK BMI WSB SEH Pre-Design Phase $ 1,900 $ 750 $ 1,100 Design Services $ 6,300 $ 7,500 $ 9,250 Construction Services, $35,600 $34,800 $30,100 Management& Inspection Antenna Services $ 5,000 $ 4,000 $ 7,000 Warrantee Inspection Included Above $ 2,800 $ 3,200 $48,800 $49,880 $50,650 City Council Meeting C:\Users\sonja.klingberg\Desktop\1-28-13 South Water Tower Proposals.doc Page 1 of 2 As can be seen from the table above, BMI provided the lowest total fee for the complete project work scope. Staff would recommend entering into a contract with BMI in an amount not to exceed $48,800 for the engineering and inspection work for the rehabilitation of the South Water Tower. A tentative schedule of the project would be as follows: • Pre-design Services February 2013 • Plans/Specifications March 2013 • Bidding April/May 2013 • Start Construction June/July 2013 • Project Complete (14 Weeks) September/October 2013 During the time that the tower is out of service, the City's water pressure and storage will be provided from a tower in Roseville's system. Roseville has already been made aware of our project. They actually have a planned tower work on their system in 2014 when our tower will provide backup to them. Council Action Requested Authorize entering into a contract with Bolton and Menk for the engineering and inspection services for the South Water Tower Rehabilitation Project on an hourly basis not to exceed $48,800.
